Prevalence of lectures about dental esthetics and female speakers in three Brazilian conferences

Abstract This study analyzed the prevalence of lectures involving esthetics in the scientific program of Brazilian dental conferences and the gender distribution of speakers. All lectures presented in three dental conferences (Bahia, São Paulo, and Goiás states) held from 2016 to 2020 were evaluated. Three investigators individually divided the lectures according to the specialties recognized by the Brazilian Federal Council of Dentistry (FCD) based on their titles. The lectures were also classified as involving or not esthetics, and the speaker`s gender was recorded. Descriptive statistical analyses were performed, and Chi-square tests assessed possible associations between factors. The words most cited in the titles of the lectures were "esthetic" (13.6%), "dentistry" (9.9%), and "treatment" (8.1%). Oral diseases were barely mentioned in the titles (up to 1.3%). The highest number of lectures was observed for the specialty of Restorative Dentistry (22.3%), followed by Prosthodontics (18.5%). Approximately one-third of lectures involved some aesthetic aspect, but this percentage ranged from 71.9 to 78.6% for the two specialties with more lectures. Regarding the speaker`s gender, the inequity was higher for lectures involving esthetics (81.6% of males) than for topics unrelated to esthetics (66.7%). More male speakers than females were observed for all specialties. The highest gender gap was observed for Pediatric Dentistry with 62.4% male speakers, although only 10.6% of FCD registered specialists were men. In conclusion, the Brazilian dental conferences analyzed seemed to favor offering lectures dealing with esthetic topics and male speakers.

Resumo Este estudo analisou a prevalência de palestras envolvendo estética na programação científica de congressos de Odontologia brasileiros, e a distribuição do gênero dos palestrantes. Todas as palestras apresentadas em três congressos de Odontologia (CIOBA, CIOGO, and CIOSP) entre 2016 e 2020 foram avaliadas. Três avaliadores utilizaram os títulos das palestras para dividi-las entre as especialidades reconhecidas pelo Conselho Federal de Odontologia (CFO) do Brasil. As palestras foram também classificadas como envolvendo ou não estética, e o gênero do palestrante foi registrado. Análises estatísticas descritivas foram realizadas, e testes de Qui-quadrado avaliaram possíveis interações entre fatores. A palavra mais citada nos títulos das palestras foi "estética" (13,6%), seguido por "odontologia" (9,9%) e "tratamento" (8,1%). Doenças orais foram raramente mencionadas nos títulos (até 1,3%). O maior número de palestras foi observado para a especialidade de Dentística (22,3%), seguido por Prótese Dental (18,3%). Aproximadamente um terço das palestras envolviam algum aspecto estético, com porcentagens entre 71,9 a 78,6% para as duas especialidades com mais palestras. Em relação ao gênero do palestrante, a inequidade foi maior para palestras envolvendo estética (81,6% de homens) que para tópicos não relacionadas à estética (66,7%). Mais palestrantes do sexo masculino que feminino foram observados para todas as especialidades. A maior discrepância entre os gêneros foi observada para Odontopediatria, uma especialidade com 62,4% dos palestrantes do sexo masculino, embora apenas 10,6% dos especialistas registrados no CFO eram homens. Como conclusão, os congressos de Odontologia Brasileiros parecem preferir palestras abordando tópicos de estética e palestrantes do sexo masculino.

COVID-19 pandemic and impact on dental education: perception of Brazilian dental students

Aim: The aim of the present study is to assess the perception of undergraduate students on the impact of the COVID-19 pandemic on Brazilian dental education. Methods: This crosssectional study was conducted using an online questionnaire hosted in Google Forms platform and publicized on Instagram® and Facebook®. The questionnaire was available between July 8-27, 2020. Absolute and relative frequencies were obtained for variables of interest using Pearson's chi-squared and considering 95% confidence intervals. Prevalence of learning resource variables according to self-reported skin color, educational institution, and Brazilian region were presented using equiplots. Results: A total of 1,050 undergraduate dental students answered the questionnaire. Most students reported being in full-distance learning mode. Among the undergraduate students, 65.4% reported perceiving a very high impact in dental education, and 16.6% of students reported not being able to follow distance learning. In addition, 14% reported not having a personal laptop or desktop to study with, with this condition being more prevalent among non-white than white individuals. Conclusion: We conclude that Brazilian dental students perceived a high impact of COVID-19 on dental education, as well as one-sixth of the students reported not having adequate resources to continue with distance learning. It is important that different policies are developed at the institutional and governmental levels to reduce the impact of the pandemic on dental education

Association among oral health and academic performance: a longitudinal study in a university in Southern Brazil

Abstract This longitudinal study aimed to investigate the association between self-perceived oral health, oral-health-related quality-of-life (OHRQoL), toothache, and university students' academic performance or dropout. A cohort of 2,089 students from 64 different courses at a public university in southern Brazil was interviewed in 2016 regarding their self-perceived oral health (Locker instrument; dichotomized into good/poor), OHRQoL (Oral Impacts on Daily Performances instrument, OIDP) and having had any toothache over the last 6 months (yes/no). After three years (2020), the academic records of 1,870 of these students were assessed, their average grade over all courses evaluated, and their dropout status was determined. Multivariable linear or logistic regression adjusting for gender, skin color, age, family income and maternal education was used to associate oral health variables (self-perceived oral health, OIDP, toothache) and academic performance or dropout. In 2016, 28.6% reported negative self-perceived oral health through the Locker instrument and 31.4% had toothache in the last 6 months. Over the next three years, 36.2% had dropped out. In multivariable regression, toothache in the last 6 months had a decrease of 0.32 (β -0.32, CI95% -0.59; -0.04) points in the final grade and were 35% (OR 1.35 CI95% 1.08; 1.69) more likely to dropout than students without toothache. In conclusion, this study showed that worse oral health conditions may be associated with worse academic performance or dropping out.

Factors associated with periodontal diseases in pregnancy: Findings of the 2015 Pelotas Birth Cohort Study

Abstract Although periodontal disease is common during pregnancy, little is known about socioeconomic, behavioral, or biological determinants related to clinically assessed periodontal condition during this period. We assessed the prevalence of periodontal disease and associated factors in pregnant women. This population-based survey used data used from the 2015 Pelotas Birth Cohort Study, Brazil. Pregnant women expected to give birth between December 2014 and May 2016 were interviewed and clinically examined by trained dentist, with periodontal measures collected in all teeth, six sites per tooth. Outcomes were periodontitis (using the 2012 Centers for Disease Control and Prevention and the American Academy of Periodontology criteria) and gingivitis (by the 2018 European Federation of Periodontology/ American Academy of Periodontology classification). Multivariate hierarchical Poisson regression was used to assess the associations between socioeconomic, systemic, and clinical oral factors and periodontal disease. A total of 2,474 pregnant women participated in the study. Prevalence of periodontitis and gingivitis was 14.63% and 21.67%, respectively. Lower educational level and calculus were associated with higher prevalence periodontitis and gingivitis (P<0.05). Smoking was also associated with periodontitis (P=0.05), and lower frequency of toothbrushing (P=0.005) with gingivitis. Periodontal disease, especially gingivitis, was prevalent in pregnant women and their determinants were socioeconomic, environmental, and clinical oral health factors.

Deep occlusal carious lesions clinical management by Brazilian dentists: a nationwide e-survey / Manejo clínico de lesões cariosas oclusais profundas por cirurgiões-dentistas brasileiros: uma pesquisa eletrônica nacional

Objective: To investigate the clinical management of deep occlusal carious lesions in permanent teeth by Brazilian dentists. Material and Methods: This cross-sectional study included a sample of 732 Brazilian dentists who responded to an electronic questionnaire composed of 20 questions addressing socio-demographic information, training and professional activity characteristics, and clinical management of deep carious lesions. Descriptive analysis was performed, considering relative and absolute frequencies and 95% confidence intervals. The association between the dentists' variables of interest (age group, type of higher education institution, years in practice, highest academic degree completed and main sector of professional activity) and the mean number of incorrect answers regarding deep carious lesions management was analyzed by Analysis of Variance (ANOVA), followed by the Bonferroni post-test (p<0.005). Results: Stepwise removal was the strategy pointed out by most dentists (42.8%). However, 16% of the dentists selected nonselective carious tissue removal. Furthermore, 45.6% of the dentists disagreed with maintaining carious tissue over the pulp in deep lesions with a risk of pulpal exposure. When using instruments to remove carious dentine, 17% of the dentists chose a diamond burn while 13% preferred tungsten carbide burs. Dentists who graduated from public institutions had a lower mean of non-conservative decisions than those from private institutions. Dentists with master's or doctoral degrees were more conservative, as well as dentists from public service compared to those from the private sector. Conclusion: The dissemination of conservative approaches in the management of deep carious lesions needs to be strengthened and increasingly based on updated scientific literature.(AU)

Objetivo: Investigar o manejo clínico de lesões cariosas oclusais profundas em dentes permanentes por cirurgiões-dentistas brasileiros. Material e Métodos: Este estudo transversal incluiu uma amostra de 732 dentistas brasileiros que responderam a um questionário eletrônico composto por 20 questões abordando informações sociodemográficas, formação, características da atividade profissional e manejo clínico de lesões cariosas profundas. Foi realizada análise descritiva, considerando frequências relativas e absolutas, e intervalos de confiança de 95%. A associação entre as variáveis de interesse (faixa etária, tipo de instituição de ensino superior, anos de prática, maior titulação acadêmica concluída e principal setor de atividade profissional) dos cirurgiões-dentistas e a média de acertos no manejo de lesões cariosas profundas foi analisada pela Análise de Variância (ANOVA), seguida do pós-teste de Bonferroni (p<0,005). Resultados: A remoção seletiva foi a estratégia apontada pela maioria dos cirurgiões-dentistas (42,8%). No entanto, 16% dos dentistas selecionaram a remoção não seletiva do tecido cariado. Além disso, 45,6% dos dentistas discordaram da manutenção de tecido cariado sobre a polpa em lesões profundas com risco de exposição pulpar. Ao usar instrumentos para remover a dentina cariada, 17% dos dentistas escolheram uma broca diamantada, enquanto 13% preferiram brocas de carboneto de tungstênio. Cirurgiões-dentistas formados em instituições públicas apresentaram menor média de decisões não conservadoras do que os de instituições privadas. Os cirurgiões-dentistas com mestrado ou doutorado foram mais conservadores, assim como os cirurgiões-dentistas do serviço público em relação aos do setor privado. Conclusão: A disseminação de abordagens conservadoras no manejo de lesões cariosas profundas precisa ser fortalecida e cada vez mais baseada em literatura científica atualizada (AU)

Analysis of dentistry content on Instagram®and the use of social networks by Brazilian dental students

Aim: The aim of our study was to analyze the content related to dentistry published on Instagram® and to investigate the students' profiles related to the use of social networks in a sample from a Dentistry School. Methods: This study was carried out in two stages. First, research was conducted to analyze content published on Instagram® related to dentistry. The second part investigated the profiles of students' from a dental school in relation to the use of social networks through a questionnaire. A descriptive analysis was performed and associations between the variables were tested using Fisher's exact test. Results: We found a diversified and large amount of content related to dentistry published on Instagram®, and publications that involved advertising were more prevalent in our study. There are also many publications that are violating the Code of Dental Ethics. In addition, in the second part of our study, we observed an enormous use of social networks by dental students (98.4%). Conclusions: As a result, we believe that it is important to update professionals about the ethical infractions related to social networks which could be approached during graduate courses in universities. Finally, the analyzed social network seems to be an interesting alternative for disseminating health information in order to dialogue with greater proximity to the large number of users who participate in it

Pandemia de COVID-19 no Brasil: quais as repercussões no comportamento, qualidade do sono, uso de telas e alimentação de crianças? / COVID-19 pandemic in Brazil: what are the impactson child behavior, sleep quality, screen time and diet?

Objetivo: Descrever as possíveis repercussões que o distan-ciamento social e pandemia de COVID-19 promoveram no comportamento, qualidade do sono, uso de telas e alimentação de crianças brasileiras de 0 a 12 anos. Materiais e Métodos: Este estudo observacional descritivo foi realizado através de um questionário on-line autoaplicado direcionado aos pais, cuidadores ou responsáveis legais de crianças de 0-12 anos. O questionário foi aplicado entre 19 de agosto de 2020 a 19 de setembro de 2020, em dois grupos, um composto por usuários de serviços de saúde e outro pela população em geral. Os da-dos foram analisados descritivamente, considerando α=5%. Resultados: Compuseram a amostra final 271 respondentes. Segundo os cuidadores, 59,4% das crianças tiveram alterações de comportamento e 48% reportou ou demonstrou medo da COVID-19. Além disso, melhora na qualidade do sono foi reportada de forma importante para crianças de até 2 anos e, 33,3% dos cuidadores em ambos os grupos reportaram piora em qualidade do sono entre 9 e 12 anos. Aumento do uso de telas ocorreu para 85% das crianças. O consumo de alimentos considerados saudáveis se manteve igual para grande parte das crianças e o consumo de alimentos ultraprocessados aumentou para mais de 40% das crianças, principalmente entre 3 e 5 anos e 9 e 12 anos de idade. Discussão: Os resultados encontrados devem ser fonte de atenção a fim de garantir o adequado desenvolvimento infantil após um período de pandemia. Conclusão: O distancia-mento social provocado pela pandemia de COVID-19 promoveu repercussões importantes na rotina das crianças avaliadas, impactando negativamente seu comportamento, alimentação e uso de telas. Ainda, a qualidade do sono de crianças maiores foi impactada negativamente, apesar de ter sido observada melhora na qualidade do sono de crianças mais jovens.

Aim: To describe the potential consequences of social distancing and the COVID-19 pandemic on the behavior, sleep quality, screen time, and diet of Brazilian chil-dren aged 0 to 12 years. Materials and methods: This descriptive observational study was conducted using a self-administered online questionnaire distributed to parents, caregivers or guardians of children aged 0-12 years. The same questionnaire was distributed to two groups between August 19, 2020 and September 19, 2020. Users of Pelotas Public Health Services made up one group, while the general Brazilian population made up the other. The data was analyzed descriptively considering α=5%. Results: The total sample consisted of 271 respondents. According to caregivers, 59.4% of children showed behavioral changes and 48% reported or demonstrated COVID-19 fear. Moreover, improve-ment in sleep quality was reported for children up to 2 years, and 33.3% of caregivers in both groups reported a decline in sleep quality among children aged 9 to 12. Eighty-five percent of children increased their screen time. The intake of healthy foods remained the same for most of the children, but the intake of ultra-processed food increased for over 40% of them, primarily between 3 to 5 years old and 9 to 12 years old. Discussion: The results should be a focus of attention in order to maintain proper child development following a pandemic. Conclusion: The social distancing caused by the COVID-19 pandemic had a significant impact on the children's routine, with negative effects on their behavior, diet and screen time. In addition, a decline in sleep quality was observed among older children, while better sleep quality was reported for younger children.

Impact of COVID-19 on gender gap in dental publications: a retrospective cohort with three Brazilian journals

Abstract This was a retrospective cohort study to investigate the impact of COVID-19 pandemic on the gender gap in articles submitted to three international dental journals based in Brazil. All submissions performed to Brazilian Dental Journal, Brazilian Oral Research, and Journal of Applied Oral Science before (2019) and during the pandemic (2020) were assessed. Gender of the first, last, and corresponding authors were collected. Other variables collected were journal, continent studied by authors and stage of their careers (classified according to authors' highest degree), and final decision reached in the article. Absolute and relative frequencies with 95% confidence intervals, Pearson's Chi-square tests, and Fisher's Exact test were used (α = 0.05). In total, 4,726 unique submissions were analyzed. A higher proportion of early-career authors was observed during the pandemic (44.8% to 49.3%, p = 0.021). Most articles were rejected but without association with gender. Increased proportion of male first authors from before to during the pandemic was observed (39% to 42.1%, p = 0.034). Drop in the proportion of articles with women as first authors was observed for researchers in their early- (65.9% to 58.8%, p = 0.02) and mid-career stages (63% to 55.8%, p = 0.014). Reduction in women as first authors was observed during the pandemic in South and Central Americas (66.7% to 61.5%, p = 0.010), and when the last author was a female, or the corresponding author was a male. In conclusion, a disproportionate impact on female dental researchers in submitting articles in the period from before to during the pandemic was observed when considering first authorship, suggesting that the COVID-19 may have increased the gender inequality in dental science.

Are maternal factors predictors of a child's first dental visit? A birth cohort study in Brazil

Abstract The purpose of this study was to investigate the association between maternal factors and dental visits of children within their first year of life. This study used data from the 2015 Pelotas Birth Cohort and included pregnant women and their children at 12 months of age, followed-up between May 2014 and December 2015. Socioeconomic and demographic data, information on the use of dental services during the last year, and information on dental fear were collected by interviewing the mothers. Information regarding dental caries and periodontal disease were collected during the mother's clinical examination. The date of each child's first visit to the dentist was recorded. Crude and adjusted Poisson regression models with robust variance were used. The sample comprised 2,287 mother-child dyads, of which 10.1% of children visited the dentist during the first year of life. Children whose mothers visited the dentist within the last year for preventive reasons (RR: 1.51; 95%CI: 1.12-2.03) or curative reasons (RR: 1.47; 95%CI: 1.08-2.01) were more likely to have visited the dentist during the first year of life compared to those whose mothers had not used dental services during this period. Maternal tooth loss was inversely associated with a child's visit to the dentist during the first year of life (RR: 0.69; 95%CI: 0.54-0.89). Considering the mother's history of using dental services, as well as their dental caries history, is necessary to understand and improve patterns of dental health care utilization and implement public oral health policies for young children.

Is professionally applied topical fluoride effective in treating incipient caries? A systematic review

Abstract The present systematic review aimed to investigate the effectiveness of professionally applied topical fluoride as therapeutic agent for incipient carious lesions in permanent teeth. Randomised clinical trials (RCTs) comparing the effectiveness of professionally applied topical fluoride (varnish or gel) with that of placebo, no intervention, and toothbrushing (control group) in the treatment of incipient carious lesions in permanent dentition were included. An electronic search was performed in the PubMed, Web of Science, Scopus, Virtual Health Library, Embase, and Cochrane databases, in the grey literature, and in clinical trials registered until January 2021. Two reviewers independently screened titles and abstracts and assessed the risk of bias using the Cochrane tool. The certainty of evidence was classified using GRADE. A total of 2,223 articles were screened using titles/abstracts. After full-text reading of the 22 selected studies, nine RCTs were included. Five RCTs found that topical fluoride may be effective in reversing incipient carious lesions in permanent teeth. Overall, five studies were classified as having a low risk of bias and four as having some concerns. Only descriptive analysis was performed because of the heterogeneity of the data. Studies comparing fluoride varnish with usual home care oral hygiene have demonstrated topical fluoride does not appear to be more effective in improving the appearance of incipient carious lesions. Therefore, usual home care oral hygiene with fluoride toothpaste may be sufficient to treat incipient carious lesions in permanent dentition. Further studies with greater methodological rigor are, however, required to reduce bias, to allow a meta-analysis, and to draw well-founded conclusions (CRD42019120406).

Medo odontológico e saúde bucal: avaliação transversal do ciclo do medo entre universitários brasileiros / Dental fear and oral health: cross-sectional evaluation of the cycle of dental fear theory among Brazilian undergraduate students

Objetivo: Avaliar a presença do medo odontológico em universitários brasileiros e observar se a teoria do ciclo vicioso do medo é identificada nesta população. Materiais e métodos: Foi realizado um estudo transversal com universitários ingressantes na Universidade Federal de Pelotas em 2016. Os dados sociodemográficos, medo odontológico, o uso de serviços odontológicos, a percepção de cárie e dor dentária foram coletados através de um questionário auto--administrado. A exposição do estudo foi medo odontológico, e os desfechos incluíram padrão de consulta odontológica, experiência de cárie e dor dentária e autopercepção de saúde bucal. Características sociodemográficas foram incluídas como fatores de confusão. Para testar a associação do medo odontológico com os desfechos, foram utilizados modelos de regressão de Poisson com variância robusta, a fim de estimar as Razões de Prevalência e Intervalos de Confiança. Resultados: Foram avaliados 2.014 universitários, dos quais 22.4% reportaram medo odontológico. Aqueles que reportaram medo odontológico apresentaram uma maior prevalência de não terem ido ao dentista no último ano e, entre os que consultaram, a visita ter sido motivada por dor/problema. Adicionalmente, ter medo aumentou a presença de cárie, dor dentária e autorrelato da saúde bucal negativa. Discussão: Os achados sugerem a presença do ciclo vicioso do medo nesta população de universitários do sul do Brasil. Conclusão: Evidenciou-se a associação entre a presença de medo odontológico e a menor procura por atendimento odontológico, a presença de cárie dentária, dor dentária e saúde bucal autorreportada negativa, corroborando com a teoria do ciclo do medo.

Aim: To evaluate the presence of dental fear among Brazilian undergraduate students and to observe whether the cycle of dental fear theory applies to this population. Materials and methods: A cross-sectional study were conducted with first year students of the Federal University of Pelotas, Brazil, in 2016. Sociodemographic data, dental fear, as well as the use of dental services and perception of caries and dental pain were collected through a self-administered questionnaire. The exposure was dental fear, and the outcomes included dental visit pattern, experience of dental caries and dental fear and self-rated oral health (SROH). Sociodemographic characteristics were included as aconfounding factor. To test the association between dental fear and the outcomes, Poisson regression models with robust variance were used, to estimate Prevalence Rations and Confidence Intervals. Results: 2,014 undergraduate students were evaluated and 22.4% of them reported dental fear. Those who reported dental fear had a higher prevalence of not visiting the dentist in the last year and, among those who visited, to have had only a pain/problem-oriented visit. Additionally, having fear increased the presence of dental caries, dental pain and negative SROH. Discussion: Our findings suggest the presence of the vicious cycle of dental fear in this population of undergraduate students in southern Brazil. Conclusion: This study provided evidence on the association between dental fear and the lower frequency of dental visit, dental caries, dental pain experience and negative SROH, corroborating with the cycle of dental fear theory.

Are stress and symptoms of depression associated with halitosis? A cross-sectional study

Mood disorders such as stress and depression can promote alterations of several hormones Aim: The present study aimed to evaluate if symptoms of depression and stress are associated with halitosis. The hypothesis is that halitosis is associated with stress and depression symptoms. Methods: All university students' entrants in the Federal University of Pelotas (UFPel) were invited to participate. Self-reported halitosis was measured using a visual analog scale. Students were also asked about the presence of halitosis perceived by close individuals. The stress level was measured using a modified version of the Perceived Stress Scale and symptoms of depression were screened by Patient Health Questionnaire-2. Poisson Regression Models were performed. Results: Of a total of 2,058 students who participated in the study, only 16% of them have reported not having any degree of halitosis and 17.6% were informed of closed individuals having halitosis. After adjustments, stress and depression symptoms remained associated with halitosis selfreported. Individuals from the higher stressed quartile presented higher scores of halitosis (RR 1.37 CI95% [1.24­1.53]). Students who presented depressive symptoms showed higher scores of self-perceived halitosis (RR 1.20 CI95% [1.10­1.32]). When the association of stress and halitosis reported by close individuals was tested, symptoms of depression lost the association in the adjusted model, while individuals from the highest quartile from stress remained associated (PR 1.36 CI95% [1.02­1.81]). Conclusion: Halitosis was associated with stress even after control for oral health and socioeconomic variables

Iniquidades socioeconômicas na saúde bucal de estudantes universitários do sul do Brasil / Socioeconomic inequities in the oral health of university students in southern Brazi

Objetivo: Identificar a magnitude da associação entre experiência de cárie dentária e autopercepção negativa de saúde bucal com determinantes socioeconômicos. Métodos: Estudo transversal realizado com dados de uma coorte prospectiva com os universitários ingressantes na Universidade Federal de Pelotas (UFPel) no ano de 2016. Os dados foram coletados por meio de questionário autoaplicável, incluindo características demográficas, socioeconômicas e psicossociais. Os desfechos do presente estudo foram a experiência de cárie autorrelatada (histórico de doença cárie) e autopercepção de saúde bucal (positiva versus negativa). Resultados: Um total de 3.237 alunos ingressou, dos quais 2.089 (64,5%) concordaram em participar do estudo. O modelo de regressão de Poisson mostrou que universitários com renda familiar de R$ 1001,00 a 5000,00 e R$ 5001,00 ou mais apresentaram, respectivamente, uma razão de prevalência (RP) 14% (RP = 0,86; IC95% 0,80-0,92) e 18% (RP = 0,82; IC95% 0,74 a 0,90) menor de experiência de cárie, assim como indivíduos cujas mães tinham ensino médio completo apresentaram uma prevalência 14% menor (RP = 0,86; IC95% 0,80 a 0,92) e ensino superior completo 19% (RP = 0,81; IC95% 0,75 a 0,87) menor de experiência de cárie, quando comparados aos grupos de referência. Na autopercepção de saúde bucal, os resultados para renda familiar de R$1001 a 5000,00 e R$ 5001 ou mais apresentaram, respectivamente, uma prevalência 23% (RP = 0,77; IC95% 0,64 a 0,91) e 43% (RP = 0,57; IC95% 0,45 a 0,72) menor de ter autopercepção de saúde bucal negativa e indivíduos cujas mães tinham ensino superior completo reportaram uma prevalência 21% menor de autopercepção de saúde bucal negativa quando comparados à referência (RP = 0,79; IC95% 0,66 a 0,97). Conclusões: Os achados do presente estudo confirmam que os indicadores socioeconômicos influenciam a experiência de cárie autorrelatada e a autopercepção de saúde bucal dos universitários.

Objective: To identify the magnitude of the association between dental caries experience and negative self-per-ception of oral health with socioeconomic determinants. Methods: Cross-sectional study conducted with data from a prospective cohort with university students entering the Federal University of Pelotas (UFPel) in 2016. Data were collected through a self-administered questionnaire, including demographic, socioeconomic and psychosocial characteristics. The outcomes of the present study were experience of self-reported caries (history of caries disease) and self-perceived oral health (positive versus negative). Results: A total of 3,237 students joined, of which 2,089 (64.5%) agreed to participate in the study. The Poisson regression model known that university students with an income of R$ 1001 to 5000.00 and R$ 5001 or more primary, respectively, a prevalence ratio (PR) 14% (PR = 0,86; 95%CI 0,80-0,92) and 18% (PR = 0,82; 95%CI 0,74 a 0,90) lower of caries experience, as well as individualizing mothers had completed high school prevalence a 14% (PR = 0,86; 95%CI 0,80 a 0,92) lower prevalence and complete higher education 19% (PR = 0,81; 95%CI 0,75 a 0,87) less caries experi-ence when compared to reference groups. In the self-perception of oral health, the results for income of R$ 1001 to 5000.00 and R$ 5001 or more dissipated, respectively, a 23% (PR = 0,77; 95%CI 0,64 a 0,91) and 43% (PR = 0,57; 95%CI 0,45 a 0,72) lower prevalence of having negative self-perception of oral health and qualified originating from complete higher education reported a 23% lower prevalence of negative self-perceived oral health when compared to the reference (PR = 0,79; 95%CI 0,66 a 0,97). Conclusions: The findings of the present study confirm that socioeconomic indicators influence the experience of caries and self-perceived oral health among university students

Ensino em saúde LGBTQI+ para alunos de odontologia: uma revisão sistemática / LGBTQI + healtheducation for dental students: a systematic review

Objetivo: investigar, na literatura odontológica, estudos que abordem diferentes aspectos do ensino de temas LGBTQI+ (Lésbicas, Gays, Bissexuais, Transexuais, População Quer, Intersexo e outros) nos cursos de odontologia e quais são as abordagens pedagógicas sugeridas para reduzir preconceitos e discriminação no atendimento odontológico. Metodologia: uma busca foi conduzida nas bases de dados PubMed, Scopus, Web of Science e BVS/Bireme, até julho de 2017. Após a remoção de duplicatas, dois revisores independentes conduziram a seleção dos artigos. Resultados: a busca inicial resultou em 924 títulos. Após leitura completa, apenas oito completaram os critérios de inclusão. Os artigos incluídos nesta revisão demonstraram que alunos, lideranças estudantis e administradores reconhecem medidas de suporte, apoio e inclusão existentes. Algumas instituições apresentaram em seu currículo temas relacionados com a população LGBTQI+, porém, relacionadas frequentemente com doenças. Essa cobertura é apontada como fraca e insuficiente para o atendimento qualificado. Apenas dois estudos apresentaram métodos para o ensino de questões LGBTQI+; entretanto, apenas um avaliou qualitativamente seus resultados. Conclusão: existe uma grande carência de estudos que descrevam abordagens e métodos de ensino de temas LGBTQI+ na odontologia.(AU)

Methods: a search was conducted in the PubMed, Scopus, Web of Science and BVS/Bireme databases, until July 2017. After removing duplicates, two independent reviewers conducted the selection of articles. Results: the initial search resulted in 924 titles. After complete reading, eight studies completed the inclusion criteria. The articles included in this review demonstrated that students, student leaders and administrators recognize support and inclusion measures. Some institutions presented topics related to the LGBTQI+ population in their curriculum, but often related to diseases. This approach was identified as weak and insufficient for a qualified service. Only two studies presented methods for teaching LGBTQI+, but only one assess qualitative results. Conclusions: there is a lack of studies that approach the education of LGBTQI+ topics mainly related to teaching methodologies.(AU)

Racial and regional inequalities of dental pain in adolescents: Brazilian National Survey of School Health (PeNSE), 2009 to 2015 / Desigualdades raciais e regionais na prevalência de dor de dente em adolescentes: Pesquisa Nacional de Saúde do Escolar (PeNSE), 2009 a 2015 / Desigualdades raciales y regionales respecto al dolor dental en adolescentes: Encuesta Nacional de Salud del Escolar (PeNSE), de 2009 a 2015

Abstract: The aim of the study is: (a) investigate the racial inequalities as one specific dimension that affects dental pain in Brazilian adolescents; and (b) investigate the regional variations of dental pain. This cross-sectional study used data from Brazilian National Survey of School Health (PeNSE), carried out with adolescents in 2009, 2012 and 2015. Dental pain was evaluated through the question: "Did you have dental pain in the last six months?". The main exposures were race and Brazilian regions, used to evaluate inequalities related to the outcome. Sex, age, school type and maternal education were used as covariables. The statistical significance of the trends in dental pain was tested using linear regression. The analysis was conducted in Stata 13.0 statistical package using the svy command. The standard prevalence of dental pain was 18.8%, 21.1% and 23.7%, showing an increasing trend over time (p < 0.001). We observed absolute inequalities in dental pain related to race and regions. A higher prevalence was found in non-white girls of public schools and in the Northern Region. The indexes of inequalities increased in the group of black girls, related to an increase of dental pain predominantly in girls whose mothers had lower educational level. It was observed that the prevalence of dental pain in Brazilian adolescents increased over time as well as its inequalities, which remained in marginalized populations and linked to Brazilian regions.

Resumo: O estudo teve dois objetivos: (a) investigar as desigualdades raciais enquanto uma dimensão específica que afeta a prevalência de dor de dente em adolescentes brasileiros, e (b) analisar as variações regionais na prevalência de dor de dente. O estudo transversal usou dados da Pesquisa Nacional de Saúde do Escolar (PeNSE), realizada com adolescentes em 2009, 2012 e 2015. Dor de dente foi avaliada com a pergunta: "Nos últimos seis meses, você teve dor de dente?". As principais exposições foram raça/cor e macrorregiões brasileiras, usadas para avaliar as desigualdades relacionadas ao desfecho. Sexo, idade, tipo de escola e escolaridade materna foram as covariáveis utilizadas. A significância estatística das tendências na prevalência de dor de dente foi testada com regressão linear. As análises foram realizadas com o programa estatístico Stata 13.0, usando o comando svy. A prevalência padrão de dor de dente foi 18,8%, 21,1% e 23,7%, com uma tendência crescente ao longo do tempo (p < 0,001). Foram observadas desigualdades absolutas na prevalência de dor de dente de acordo com raça e macrorregião. A prevalência mais alta esteve associada ao sexo feminino, raça não-branca, escola pública e Região Norte do país. Os índices de desigualdade aumentaram no grupo de meninas negras, refletidos em um aumento na prevalência de dor de dente em meninas cujas mães tinham menos escolaridade. A prevalência de dor de dente em adolescentes brasileiros aumentou ao longo do tempo, e as desigualdades em relação à dor de dente persistiram nas populações marginalizadas e de acordo com a região do país.

Resumen: El objetivo del estudio fue doble: (a) investigar las desigualdades raciales, como una dimensión específica que afecta al dolor dental, en adolescentes brasileños; e (b) investigar las variaciones regionales del dolor dental. Este estudio transversal usó datos de la Encuesta Nacional de Salud del Escolar (PeNSE), llevada a cabo con adolescentes en 2009, 2012 y 2015. El dolor dental fue evaluado por la pregunta: "En los últimos seis meses, ¿sufriste dolor dental?". Los principales factores de exposición fueron raza y regiones brasileñas, y se usaron para evaluar las desigualdades relacionadas con los resultados. Sexo, edad, tipo de escuela y educación maternal fueron las covariables usadas. La significación estadística de las tendencias en el dolor dental fue probada usando regresión lineal. El análisis se realizó con el paquete estadístico Stata 13.0, usando el comando svy. El estándar de prevalencia de dolor dental fue 18,8%, 21,1% y 23,7%, con tendencia a aumentar a lo largo del tiempo (p < 0.001). Se observaron desigualdades absolutas en el dolor dental, relacionadas con raza y regiones. Se encontró una prevalencia más alta en chicas, de raza no blanca, escuelas públicas y Región del Norte. Los índices de desigualdades se incrementaron en el grupo de chicas negras, en detrimento de un incremento en la prevalencia del dolor dental en chicas cuyas madres contaban con menos educación formal. Se observó que la prevalencia de dolor dental en adolescentes brasileñas se incrementó a lo largo del tiempo y las desigualdades, respecto al dolor dental, continuaron manteniéndose en el tiempo en poblaciones marginalizadas y acordes con determinadas regiones brasileñas.

Normative and subjective need for dental prosthesis: accuracy and agreement in a population based-study / Necessidade normativa e subjetiva de próteses dentárias: acurácia e concordância em um estudo populacional / Necesidad normativa y subjetiva de prótesis dentales: precisión y concordancia en un estudio poblacional

Abstract: The aim of our study was to compare normative need for dental prosthesis (estimated by dentists) with subjective need (self-reported) by testing the accuracy and agreement and comparing direction and magnitude of associations with independent variables using both as outcomes. A representative sample of a birth cohort study (n = 900) was assessed at 31 years of age. Subjective need was obtained from questionnaire. Both normative and subjective need variables were dichotomized in (a) individuals with need for dental prosthesis and (b) without need for dental prosthesis. Accuracy was assessed by sensitivity (SE), specificity (SP), positive (PPV) and negative (NPV) predictive values. Agreement of normative and subjective need was assessed estimating kappa index. Sex, income, educational level, use of dental services and self-reported oral health were used to compare the associations with normative and subjective need. Prevalence of normative need was 48.9% and subjective need was 34.9%. Agreement (kappa: 0.43) and accuracy between normative and subjective need for dental prosthesis was low (SE: 56.5, 95%CI: 50.3-62.6; SP: 85.8, 95%CI: 81.1-89.7; PPV: 79.1, 95%CI: 72.6-84.7; NPV: 67.3, 95%CI: 62.1-72.2). When considering individuals with loss in anterior teeth, results showed a good agreement (kappa: 0.82) and accuracy between normative and subjective need (SE: 93.3, 95%CI: 68.1-99.8; SP: 88.9, 95%CI: 51.8-99.7; PPV: 93.3, 95%CI: 68.1-99.8; NPV: 88.9, 95%CI: 51.8-99.7). Direction and magnitude of associations with normative and subjective need were similar. Thus, normative need for dental prosthesis differs from subjective need in adults, except when anterior losses are present.

Resumo: O estudo teve como objetivo comparar a necessidade normativa de prótese dentária (estimada por dentista) com a necessidade subjetiva (autorrelatada), testando a acurácia e concordância e comparando a direção e magnitude das associações com variáveis independentes, usando necessidade normativa e subjetiva como os desfechos. Foi avaliada uma amostra representativa de uma coorte de nascimentos (n = 900), aos 31 anos de idade. A necessidade subjetiva foi obtida com um questionário. As variáveis necessidade normativa e subjetiva foram analisadas dicotomicamente como: (a) com necessidade de prótese dentária e (b) sem necessidade de prótese dentária. A acurácia foi avaliada enquanto sensibilidade (SE), especificidade (SP), valor preditivo positivo (VPP) e valor preditivo negativo (VPN). A concordância entre necessidade normativa e subjetiva foi avaliada com a estimativa do índice kappa. Sexo, renda, escolaridade, uso de serviços de odontologia e percepção da própria saúde oral foram usados para comparar as associações entre necessidade normativa e subjetiva. A prevalência de necessidade normativa era 48,9% e de necessidade subjetiva, 34,9%. A concordância (kappa: 0,43) e acurácia entre as necessidades normativa e subjetiva de prótese dentária eram baixas (SE: 56,5, IC95%: 50,3-62,6; SP: 85,8, IC95%: 81,1-89,7; VPP: 79,1, IC95%: 72,6-84,7; VPN: 67,3, IC95%: 62,1-72,2). Nos indivíduos com perda de dentes anteriores, os resultados mostraram boa concordância (kappa: 0,82) e acurácia entre necessidade normativa e subjetiva (SE: 93,3, IC95%: 68,1-99,8; SP: 88,9, IC95%: 51,8-99,7; VPP: 93,3, IC95%: 68,1-99,8; VPN: 88,9, IC95%: 51,8-99,7). A direção e magnitude das associações com necessidade normativa e subjetiva eram semelhantes. Portanto, a necessidade normativa de prótese dentária difere da necessidade subjetiva em adultos, exceto quando há perda de dentes anteriores.

Resumen: El objetivo de este estudio fue comparar la necesidad normativa de prótesis detal -estimada por los dentistas- con la necesidad subjetiva -autoinformada-, probando la precisión y concordancia, así como comparando la dirección y magnitud de asociaciones con variables independientes, usando ambas como resultados. Se evaluó una muestra representativa de un estudio de cohorte de nacimientos (n = 900) a los 31 años de edad. La necesidad subjetiva procede de un cuestionario. Ambas variables necesidad normativa y subjetiva fueron dicotomizadas en (a) individuos con necesidad de una prótesis dental y (b) sin necesidad de una prótesis dental. La precisión se evaluó por sensibilidad (SE), especificidad (SP), valores predictivos positivos (PPV) y negativos (NPV). La concordancia entre necesidad normativa y subjetiva se evaluó estimando el índice de kappa. Sexo, ingresos, nivel educacional, uso de servicios dentales y autoinformados de salud oral se usaron para comparar las asociaciones con necesidad normativa y subjetiva. La prevalencia de necesidad normativa fue 48,9% y la de necesidad subjetiva fue 34,9%. Concordancia (kappa: 0,43) y precisión entre la necesidad normativa y subjetiva de prótesis dental fue baja (SE: 56,5, IC95%: 50,3-62,6; SP: 85,8, IC95%: 81,1-89,7; PPV: 79,1, IC95%: 72,6-84,7; NPV: 67,3, IC95%: 62,1- 72,2). Cuando consideramos a individuos con pérdidas de dientes anteriores, los resultados mostraron una buena concordancia (kappa: 0,82) y precisión entre necesidad normativa y subjetiva (SE: 93,3, IC95%: 68,1-99,8; SP: 88,9, IC95%: 51,8-99,7; PPV: 93,3, IC95%: 68,1-99,8); NPV: 88,9, IC95%: 51,8-99,7). La dirección y magnitud de las asociaciones con necesidad normativa y subjetiva fueron similares. Por lo tanto, la necesidad normativa de prótesis dentales difiere de la necesidad subjetiva en adultos, excepto cuando están presentes las pérdidas de dientes anteriores.

Objetivo: Analisar a associação entre dor dentária, uso de serviços odontológicos e absenteísmo escolar em adolescentes brasileiros. Métodos: Estudo transversal, sobre dados da Pesquisa Nacional de Saúde do Escolar (PeNSE 2015). A variável dependente do estudo foi o absenteísmo escolar por motivo de saúde nos últimos 12 meses. Características socioeconômicas, dor dentária e utilização de serviços odontológicos foram as variáveis independentes avaliadas. Empregou-se regressão logística, para estimar odds ratio (OR) e respectivos intervalos de confiança de 95% (IC95%). Resultados: Foram incluídos 102.072 escolares. A prevalência de absenteísmo por motivo de saúde foi de 53,7% (IC95% 53,2;54,3). Pela análise ajustada, houve associação entre dor dentária e absenteísmo (OR=1,35 - IC95% 1,26;1,45), e aumento na ocorrência de absenteísmo conforme o maior número de consultas odontológicas. Conclusão: Os resultados sugerem que a dor dentária e a frequência de consultas odontológicas podem estar relacionadas ao absenteísmo escolar.

Objetivo: Analizar la asociación entre dolor dental, el uso de servicios dentales y el absentismo escolar en adolescentes brasileños. Métodos: Estudio transversal con datos de la Encuesta Nacional de Salud Escolar (PeNSE 2015). La variable dependiente del estudio fue el absentismo escolar por razones de salud en los últimos 12 meses. Características socioeconómicas, dolor dental y frecuencia del uso de los servicios dentales fueron las variables independientes evaluadas. La regresión logística se usó para estimar los odds ratio (OR) e intervalos de confianza del 95% (IC95%). Resultados: Se incluyeron datos de 102.072 estudiantes. La prevalencia de absentismo por razones de salud fue del 53,7% (IC95% 53,2; 54,3). En el análisis ajustado, hubo una asociación entre el dolor dental y el absentismo escolar (OR=1,35; - IC95% 1,26; 1,45), y un aumento del absentismo según el mayor número de consultas dentales. Conclusión: Los resultados sugieren que el dolor dental y la frecuencia de las visitas al dentista pueden estar relacionados con el absentismo escolar.

Objective: To analyze association between dental pain, use of dental services and school absenteeism in Brazilian adolescents. Methods: This was a cross-sectional study with data from the National School Health Survey (PeNSE 2015). The study's dependent variable was school absenteeism due to health reasons in the last 12 months. Socioeconomic characteristics, dental pain and use of dental services were the independent variables evaluated. Logistic regression was used to estimate odds ratios (OR) and respective 95% confidence intervals (95%CI). Results: Data on 102,072 schoolchildren were included. Absenteeism prevalence due to health reasons was 53.7% (95%CI 53.2;54.3). In the adjusted analysis, there was association between dental pain and school absenteeism (OR=1.35 - 95%CI 1.26;1.45), and an increase in absenteeism occurrence the greater the number of dental visits. Conclusion: The results suggest that dental pain and frequency of dental visits may be related to school absenteeism.

Triple-blinded randomized clinical trial comparing efficacy and tooth sensitivity of in-office and at-home bleaching techniques

Abstract Objective Our study aims to compare the efficacy and tooth sensitivity following in-office (35% hydrogen peroxide) or at-home (10% carbamide peroxide) bleaching treatments both preceded by 2% potassium nitrate (2%KF) desensitizing gel. Methodology 130 volunteers were randomly allocated to a) in-office bleaching and a placebo at-home protocol; or b) in-office placebo and at-home bleaching treatment. 2% KF was applied for 10 min before both treatments. Objective color evaluation was performed (spectrophotometer CIEL*a*b* system and CIEDE2000) to calculate the color change (ΔE00). Subjective evaluation was performed using the VITA classical shade guide followed by shade variation (ΔSGU) at the beginning and end of bleaching treatment and 2 weeks post-bleaching. Tooth sensitivity was daily recorded using a Likert scale varying from 1 (no sensitivity) to 5 (severe sensitivity). Analysis was carried out using non-parametric tests. Results Regarding the color change, at-home bleaching resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.003) and Δa* (p=0.014). Two weeks post-bleaching, the at-home treatment resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.037) and ΔE00 (p=0.033). No differences were observed in either ΔSGU parameters. Concerning sensitivity, patients treated with in-office bleaching reported more tooth sensitivity than the at-home group only on the first day after bleaching started, without significant differences in the other periods evaluated (p>0.05). Conclusions At-home and in-office bleaching, preceded by a desensitizing agent, were effective for vital teeth bleaching and 10% carbamide peroxide produced a higher whitening effect than 35% hydrogen peroxide in the short time evaluation. Tooth sensitivity rates were similar for the two techniques tested.

A Bibliometric analysis of articles published in Brazilian Dental Journal over 30 years

Abstract This study assessed bibliometric characteristics of all articles published in Brazilian Dental Journal (BDJ) in its 30 years of existence (1990-2019) and factors associated with citation rates. A document search was carried out in Scopus in December, 2019 and information about the articles were exported, including citations. Type of study and main subject in each article were categorized. Number of citations was categorized in tertiles. Logistic regression models were used to assess the association between variables related to articles' characteristics and number of citations. In 30 years, 1705 articles were published and 18507 citations received, with average 57 articles and 334 pages published yearly and 10.9 cites/doc. The most frequent types of study were laboratorial (63%), clinical (18.5%), and case reports (11%); the main subjects were dental materials (21.6%), endodontics (19.3%), and oral pathology/stomatology (13.1%). Most articles had origin in Brazil (90%), followed by USA (4.6%) and UK (1.5%). Aside from BDJ, Journal of Endodontics (3.5%) and International Endodontic Journal (2.2%) were journals that most often cited BDJ. Main origins of citations were Brazil (36.7%), USA (10.6%), and India (9%). Older articles had higher odds to be highly cited (12% increase/year), longer articles had lower odds (9% decrease/page). Narrative reviews and epidemiological studies were associated with more citations and systematic reviews with less citations. In conclusion, BDJ covered many subjects and study types in 30 years, showing increased growth in international audience. The journal may be regarded as one of the leading Brazilian journals in dentistry published in English.
