ABSTRACT

Aim: This study aimed to compare the microbiological potential and gustatory perception of essential oils (EO) mouthrinses containing and not containing alcohol. Methods: Twenty healthy adult volunteers rinsed with 10mL of the following test solutions: EO with alcohol, EO without alcohol, or a control solution (saline solution with mint essence). A washout period of at least seven days was adopted after a single-use protocol of the respective solution. All participants used all three tested substances. Antimicrobial potential was assessed by counting salivary total viable bacteria both before and after each rinse. Gustatory perception was evaluated using the Visual Analogue Scale (VAS). Multiple comparisons were performed with the Wilcoxon test, using Bonferroni correction. Results: Both EO solutions presented a higher antimicrobial potential in comparison to the control solution (p<0.017). However, no significant difference in antimicrobial potential was observed between EO containing or not containing alcohol (p=0.218). VAS of EO with alcohol (median: 2.7) was similar to control solution (median: 1.6) (p=0.287). A better gustatory perception was observed of the EO without alcohol (median 7.6) when compared to the control solution (p<0.0001). When EO groups were compared, EO without alcohol also demonstrated a significantly better gustatory perception (p=0.001). Conclusion: Mouthrinse containing EO without alcohol presented a better taste perception when compared to the EO with alcohol, but no difference was observed in the antimicrobial potential of both EO solutions after a single rinse protocol

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Temporomandibular disorders (TMD) are a group of conditions characterized by changes in the movements and function of the orofacial region and one of main reported symptoms is pain. As it has been increasingly described among different age groups, this study aimed to evaluate the presence of symptoms of TMD and their possible associated factors in older people from a city in southern Brazil. METHODS: A cross-sectional household-based study using a per cluster sampling strategy was performed including 282 older adults aged ≥60 years in the city of Veranópolis/RS. A clinical oral examination and a structured questionnaire were applied. TMD symptoms were evaluated with Fonseca Anamnestic Index (FAI) questionnaire and divided into those "without TMD" and "with TMD" (the later including those reporting mild, moderate and severe TMD symptoms). Associations were performed by the chi-square or Mann-Whitney tests based on frequency distribution. Bi and multivariate analyses were performed using Poisson regression with robust variation to verify associations. RESULTS: Prevalence among older adults that reported symptoms of TMD was 30.5% (n=86). In the final multivariate model, female older adults presented higher prevalence ratio (PR) for symptoms of TMD, presenting 62.8% (p=0.040) higher PR to at least mild symptoms of TMD when compared to older adult men. Number of teeth, need for dental prosthesis or other demographic variables were not associated with symptoms of TMD. CONCLUSION: The results demonstrated a prevalence of TMD symptoms in the seniors of approximately 30%, which was most associated with females. Despite its relevance in public health strategies focused on older adults, these findings should be interpreted with caution due to their observational and cross-sectional nature.


RESUMO JUSTIFICATIVA E OBJETIVOS: As disfunções temporomandibulares (DTM) são um grupo de condições caracterizadas por alteração dos movimentos e função da região orofacial e um dos maiores sintomas relatados é a dor. Como estas disfunções têm sido descritas de forma crescente entre diversas faixas etárias, o objetivo deste estudo foi avaliar a presença de sintomas de DTM e seus possíveis fatores associados em idosos de uma cidade do sul do Brasil. MÉTODOS: Estudo transversal de base domiciliar com amostra probabilística por conglomerado incluindo 282 idosos com idade ≥60 anos da cidade de Veranópolis/RS. Um exame clínico de saúde bucal e questionário estruturado foram aplicados. Sintomas de DTM foram avaliados pelo Índice Anamnésico de Fonseca (IAF) e categorizados em "Sem DTM" e "Com DTM", sendo que o último incluiu aqueles com sintomas compatíveis com DTM, moderada ou grave. Associações foram avaliadas pelos testes de Qui-quadrado ou Mann-Whitney por distribuição de frequências. Análises bi e multivariadas foram realizadas utilizando-se regressão de Poisson com variância robusta para verificar associações. RESULTADOS: A prevalência de idosos que relataram sintomas de DTM foi de 30,5% (n=86). No modelo multivariado final, idosas do sexo feminino apresentaram maior razão de prevalência (RP) para sintomas de DTM, apresentando 62,8% maior RP (p=0,040) de ter, pelo menos, sintomas leves de DTM quando comparados a idosos do sexo masculino. O número de dentes presentes, necessidade de prótese ou outras variáveis demográficas não estiveram associadas com a presença de sintomas de DTM. CONCLUSÃO: Os achados do presente estudo demonstraram prevalência de sintomas de DTM em idosos de aproximadamente 30%, com maior associação com o sexo feminino. Apesar de relevantes para delineamento de estratégias de saúde para idosos, os achados do presente estudo devem ser interpretados com cautela por sua natureza observacional e transversal.

ABSTRACT

Abstract This study aimed to evaluate the oral health-related quality of life (OHRQoL) and associated factors in the elderly. A cross-sectional study was conducted with 287 elderly of Cruz Alta, Brazil. The following variables were collected: age, sex, ethnicity, level of education, marital status, retirement, medical/dental history, smoking/alcohol exposure, oral hygiene habits, use and need of dental prosthesis, missing teeth, temporomandibular disorder symptoms (TMD), nutritional status, and halitosis. OHRQoL was assessed by Oral Health Impact Profile-14 (OHIP-14). The sample was categorized into low impact (sum scores ≤6) and high impact (sum scores ≥7). Associations were analyzed by Poisson regression with robust variation. Mean scores of OHIP-14 was 5.92±8.54. Divorced individuals and those who did not use dental floss presented 77% and 54%, respectively, higher prevalence ratio (PR) of having higher OHRQoL impact. Elderly that did not need dental prosthesis demonstrated a lower impact on OHRQoL (P<0.01). Elderly with TMD presented a higher PR of having higher OHRQoL impact (P<0.01). It was concluded that higher impact on OHRQoL was associated with marital status, non-users of dental floss and those with TMD. No need dental prosthesis were associated with lower impact on OHRQoL.


Resumo O estudo avaliou a qualidade de vida relacionada à saúde bucal (QVRSB) e fatores associados em idosos. Estudo transversal foi realizado em 287 idosos de Cruz Alta, Brasil. As seguintes variáveis foram coletadas: idade, sexo, etnia, nível educacional, estado civil, aposentadoria, histórico médico/odontológico, exposição ao fumo/álcool, hábitos de higiene oral, uso e necessidade de prótese, dentes ausentes, sintomas de desordem temporomandibular (DTM), estado nutricional e halitose. QVRSB foi avaliada pelo OHIP-14 (Perfil de Impacto de Saúde Bucal) e categorizado em baixo impacto (soma dos escores ≤6) e alto impacto (soma dos escores ≥7). Associações foram avaliadas por regressão de Poisson com variância robusta. A média OHIP-14 foi 5,92±8.54. Indivíduos divorciados e aqueles que reportaram não usar fio dental apresentaram 77% e 54%, respectivamente, maior razão de prevalência (RP) de terem maior impacto na QVRSB. Idosos que não necessitam próteses dentárias demonstraram menor impacto na QVRSB (P<0,01). Além disso, idosos com DTM apresentaram maior RP de terem maiores escores de OHIP-14 (P<0,01). Foi concluído que maiores impactos na QVRSB estão associados com estado civil, não uso de fio dental e DTM. Não necessitar de prótese dentária esteve associado com menores impactos na QVRSB.

ABSTRACT

OBJECTIVE: This study aimed to assess the prevalence of concern with oral health and associated factors among older adults. METHODS: Individuals aged >60 years were included from the cities Cruz Alta and Veranopolis, Brazil. Oral health examination and a structured questionnaire were applied in 569 individuals. The main outcome was concern with oral health (yes or no), which was determined by a validated questionnaire. Uni- and multivariate analyses were conducted by Poisson regression with robust variance to assess the association between outcome and independent variables. RESULTS: The prevalence of concern with oral health was 30.58% (n = 174). Non-white individuals presented significantly higher prevalence ratio (PR) of being concerned about their oral health (PR = 1.28; 95% confidence interval [CI] 1.01-1.62). Individuals with medium or high level of education, not retired and without any health problems presented higher PR of being concerned with their oral health when compared to their controls (p < 0.05). Moreover, those that reported toothbrushing frequency > 2 times/day (PR = 1.58; 95%CI 1.01 - 2.48) and non-edentulous (PR = 1.50; 95%CI 1.12 -2.01) also presented higher PR of being concern with their oral health. Older adults that were not concerned with tooth alignment (PR = 0.57; 95%CI 0.44 - 0.74) or tooth color (PR = 0.41; 95%CI 0.31 - 0.54) demonstrated lower concern with their oral health. CONCLUSION: Prevalence of concern with oral health among the older adults was low and associated with non-white individuals, medium and high level of education, individuals not retired, absence of health problems, higher toothbrushing frequency, mild temporomandibular disorder (TMD) and non-edentulism. Additionally, concern with esthetical aspects may be related with this outcome.


OBJETIVO: Esse estudo objetivou verificar a prevalência de preocupação com a saúde bucal e fatores associados em idosos. METODOLOGIA: Idosos com idade ≥60 anos foram incluídos das cidades de Cruz Alta e Veranópolis, Brasil. Exame de saúde bucal e um questionário estruturado foram aplicados em 569 indivíduos. O desfecho primário foi preocupação com saúde bucal (sim ou não), a qual foi determinada por um questionário validado. Análises uni- e multivariadas foram realizadas por meio de regressão de Poisson com variância robusta para verificar a associação entre o desfecho e as variáveis independentes. RESULTADOS: A prevalência de preocupação com a saúde bucal foi de 30,58% (n = 174). Indivíduos não brancos apresentaram razão de prevalência (RP) significativamente maior de serem preocupados com a sua saúde bucal (RP = 1,28 ­ intervalo de confiança [IC] de 95% 1,01 ­ 1,62). Indivíduos com nível educacional médio ou alto, não aposentados e sem qualquer problema de saúde apresentaram maior RP de serem preocupados com sua saúde bucal quando comparados com seus controles (p < 0,05). Além disso, idosos que reportaram escovar os dentes ≥ 2 vezes/dia (RP = 1,58; IC95% 1,01 ­ 2,48) e não edêntulos (RP = 1,50; IC95% 1,12 ­ 2,01) também apresentaram maior RP de serem preocupados com sua saúde bucal. Idosos não preocupados com alinhamento dentário (RP = 0,57; IC95% 0,44 ­ 0,74) ou com a cor dos dentes (RP = 0,41; IC95% 0,31 ­ 0,54) demonstraram menor preocupação com a saúde bucal. CONCLUSÃO: Prevalência de preocupação com a saúde bucal em idosos foi baixa e associada com indivíduos não brancos, com nível educacional médio ou alto, indivíduos não aposentados, ausência de problemas de saúde, alta frequência de escovação, desordem temporomandibular (DTM) leve e não edêntulos. Além disso, preocupação com aspectos estéticos pode estar relacionada com isso.

ABSTRACT

Aim: To explore socioeconomic, educational and research factors associated with dental research productivity at the state level in Brazil. Methods: The authors used the Scopus database to identify dental articles published from 2006 to 2016 associated with Brazilian universities at the state level. Several social, economic, educational and research structure variables were obtained from the census and National Research Council to predict the rate of articles per 100 thousand inhabitants among the 27 Brazilian states. Rates were fitted in linear weighted least-squared regression with stepwise technique. Twenty-two variables were grouped in six blocks (social, economic, general education, dental education, research workforce and structure). Results: A total of 21189 articles were published, and the state of São Paulo accounted for 46%, followed by Rio Grande do Sul with 9.4%; four states did not publish any articles. There were an average (± standard deviation) of 2.6 (±1.98) published articles per 100 researchers and 13.4 (±9.6) articles per 100 thousand inhabitants. Research structure and workforce explained 92.4% and 87.2% of state variability, respectively, while the final model explained 94.5%. One extra PhD and one extra undergraduate researcher per 100 thousand inhabitants were associated with 11.3 more and 3.5 fewer articles, respectively, while every 10 points (range 0-100) on the Human Development Index (Education Component) was associated with 3.3 more articles. Conclusion: State scientific output has several associated factors, but research workforce and general education variables seem to be good predictors. Large disparities among state research outputs have been described and must be addressed by research and development policies

ABSTRACT

Aim: This study aimed to evaluate the prevalence of concern with dental appearance (DA) and associated factors among the elderly of two southern Brazilian cities. Methods: A cross-sectional study was conducted in the cities of Cruz Alta and Veranópolis, Brazil. Oral health examination and a structured questionnaire were applied. Questions from the PCATool-SB Brasil tool and the Questionnaire about Teeth Appearance, both validated to Brazilian samples, were used. The collected independent variables were: sex, age, ethnicity, education level, marital status, retirement, health problem, use of medication, smoking exposure, alcohol exposure, access to the dentist, toothbrushing frequency, use of dental floss, edentulism, use of and need for dental prosthesis. Concern with DA was dichotomized into yes/no. Associations between dependent and independent variables were assessed by Chi-square or Mann-Whitney tests. Moreover, uni- and multivariate analyses were conducted by Poisson regression with robust variance. Level of significance was established as p<0.05. Results: The prevalence of concern with DA was 18.8% (n=107). The prevalence ratio (PR) of concern with DA decreased 5.8% for each year increase (PR:0.942; 95% confidence interval [95%CI]:0.911­0.973). Elderly without access to the dentist in the last 12 months presented 62.5% (p=0.006) higher PR of concern with DA when compared to those with access to dental care. Dentate elderly showed 219% higher PR for concern with DA (PR:2.197; 95%CI:1.364­3.539) in comparison to edentulous individuals. Conclusion: Prevalence of concern with DA was low and associated with demographics, access to dental care and edentulism

ABSTRACT

Abstract The precautionary principle is part of evidence-based healthcare and is used both preventively and therapeutically when there is no available evidence about how to manage problems/diseases/conditions that are especially life-threatening. However, since it is not always based in the most qualified evidence, it is frequently questioned. The emergence of a highly contagious disease, with increased levels of morbimortality, an acute respiratory syndrome, the so called Coronavirus Disease 2019 (COVID-19), led health professionals to look for the best alternatives to save lives. In this sense, the precautionary principle was evocated. The aim of this paper is to make a reflection about the precautionary principle, the dental profession and COVID-19. It is important to have in mind that in such a disease, guidelines, protocols and approaches can change very fast, since a continuous evaluation of all policies is mandatory. During the pandemic, elective procedures may be restricted, but international organizations removed the recommendation to postpone elective procedures. Clinicians are advised to be updated about their local current policies. On the other hand, there are cases in which in-office dental care is unavoidable, such as individuals with pain, spontaneous bleeding and dental trauma. Biosafety is upmost importance when seeking patients during pandemic. In this sense, it was concluded that precautionary principle should be, therefore, used. However, caution needs to be taken and continuous surveillance necessary.

ABSTRACT

Abstract This study aimed to assess the effects of low molecular weight heparin (LMWH) on alveolar bone loss (ABL), blood count, and counting of megakaryocytes and adipocytes in male Wistar rats. Forty male 60-day Wistar rats were randomly divided into four groups: Control (C), Periodontal Disease (PD), Heparin (Hp) and Heparin + Periodontal Disease (Hp+PD). LMWH was applied for 60 days at doses of 1 ml/kg/day. Blood samples were collected at baseline, 30 and 60. On day-49, PD and Hp+PD groups were subjected to ligature-induced periodontitis around second upper right molar. The left side was assessed as spontaneous alveolar bone loss. Mean ABL in the side with ligature showed significantly different between C (0.35±0.07 mm) and Hp+DP (0.49±0.09 mm) groups (p<0.001), between PD (0.55±0.11 mm) and Hp (0.32±0.06 mm) groups (p<0.001) and between Hp and Hp+DP groups (p<0.001). No significant differences were found among groups for ABL in the side without ligature. Animal weight, food intake, and water consumption showed no statistically significant difference among groups. Megakaryocytes and adipocytes were counted using optical microscopy and no statistically significant differences were found. Within-groups, there were an increase and a decrease, respectively, in the counting of lymphocytes (p=0.005 for C and p=0.009 for Hp+PD groups only) and leukocytes (p=0.003 for C, p=0.001 for PD, p=0.002 for Hp, and p<0.001 for Hp+PD groups). There was no decrease in the number of platelets in the three collection periods. LMWH was not able to affect ABL, but it may change the blood counting, especially increasing lymphocytes.


Resumo O presente estudo objetivou verificar o efeito da heparina de baixo peso molecular (HBPM) sob a perda óssea alveolar (POA), contagem de células sanguíneas, megacariócitos e adipócitos em ratos Wistar machos. Quarenta ratos Wistar de 60 dias foram randomicamente divididos em quatro grupo: Controle (C), Doença Periodontal (DP), Heparina (Hp) e Heparina + Doença Periodontal (Hp+DP). HBPM foi aplicada durante 60 dias em doses de 1 mL/kg/dia. Coletas sanguíneas foram realizadas nos dias 0, 30 e 60. No dia 49, os grupos DP e Hp+DP receberam indução de doença periodontal por ligadura ao redor do segundo molar superior direito. No lado esquerdo, verificou-se perda óssea alveolar espontânea. A média de POA no lado com ligadura mostrou-se estatisticamente diferente entre os grupos C (0,35±0,07 mm) e Hp+PD (0,49±0,09 mm) (p<0,001), entre os grupos DP (0,55±0,11 mm) e Hp (0,32±0,06 mm) (p<0,001) e entre os grupos Hp e Hp+DP (p<0,001). Nenhuma diferente significativa foi observada entre os grupos no lado sem ligadura. Peso dos animais, consumo de ração e ingestão de água não mostraram diferenças significativas entre os grupos. Megacariócitos e adipócitos foram contados por microscopia óptica e nenhuma diferença significativa foi encontrada. Dentro dos grupos, houve um aumento e uma diminuição, respectivamente, na contagem de linfócitos (p=0,005 no grupo C e p=0,009 no grupo Hp+DP somente) e leucócitos (p=0,003 no grupo C, p=0.001 no grupo DP e p=0,002 no grupo Hp e Hp+DP). Não houve diminuição no número de plaquetas nos três períodos de coleta. HBPM não foi capaz de modificar a POA, porém modificou a contagem de células sanguíneas, especialmente aumentando o número de linfócitos.

ABSTRACT

O objetivo do estudo foi avaliar bem-estar psicológico, saúde geral e fontes de estresse de estudantes de Odontologia de quatro cursos, comparando as fases pré-clínica e clínica e os sexos. Três instrumentos foram aplicados: Dental Environment Stress (DES), Psychological General Well-Being Index (PGWB) e Health Survey (SF-36), respondidos por 203 estudantes, sendo 75 (37%) em fase pré-clínica e 128 (63%) em clínica. Desses, 59 (29%) eram homens e 144 (71%) mulheres. As comparações foram realizadas pelo teste de Mann-Whitney, adotando um nível de significância de 5%. Nos domínios analisados pelo DES (performance acadêmica; dificuldades e inseguranças sobre o futuro profissional; responsabilidade com pacientes; fatores pessoais e institucionais; relações interpessoais), estudantes em fase pré-clínica demonstraram escores significativamente menores quando comparados a estudantes em fase clínica. No escore total de PGWB e em dois domínios (ansiedade e saúde geral), observou-se também escores menores em estudantes em fase pré-clínica. Quatro domínios do SF-36 (dor corporal, funcionamento físico, funcionamento social e papel físico), apresentaram significativa melhor saúde geral dos estudantes em fase pré-clínica. Entre os sexos, dois domínios do DES (performance acadêmica, dificuldade e insegurança sobre o futuro profissional) mostraram menores fatores estressores para o sexo masculino. O PGWB demonstrou diferença significativa em quatro domínios (estado deprimido; autocontrole; saúde geral; vitalidade), com melhor bem-estar psicológico para homens. O sexo masculino apresentou melhor vitalidade no domínio do SF-36. Concluiu-se que estudantes em fase pré-clínica e do sexo masculino demonstraram menores fontes de estresse, melhor bem-estar psicológico e percepção de saúde geral (AU).


The aim of this study was to evaluate psychological well-being, overall health, and sources of stress among dental students from four Doctor of Dental Surgery (DDS) programs, comparing the preclinical and clinical phases and sexes. Three instruments were applied: Dental Environment Stress (DES), Psychological General Well-Being Index (PGWB) and Health Survey (SF-36), answered by 203 students, with 75 (37%) in the preclinical phase and 128 (63%) in the clinical one. Among them, 59 were male (29%) and 144 were female (71%). Comparisons were performed using the Mann-Whitney test, adopting a significance level of 5%. In the domains analyzed using DES (academic performance, difficulties and insecurities about their professional future, responsibilities with patients, personal and institutional factors, interpersonal relationships), preclinical students showed significantly lower scores than students enrolled in the clinical phases. For PGWB total score and in two domains (anxiety and general health), lower scores were also observed in preclinical students. Four domains of SF-36 (bodily pain, physical functioning, social functioning and role-physical) showed significantly better overall health for preclinical students. Among the sexes, two DES domains (academic performance and difficulties and insecurities about their professional future) showed lower stressors for males. PGWB showed a significant difference in four domains (depressed mood, self-control, general health and vitality), with better psychological well-being for males. Males showed better vitality in the SF-36 domain. Concluding, preclinical and male students showed lower sources of stress, better psychological well-being and better perception of their overall health (AU).

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: To assess the prevalence of temporomandibular dysfunction symptoms and the associated factors in the elderly of a city in southern Brazil. METHODS: A cross-sectional observational study performed in residential homes, with probabilistic cluster sample, interviewed and examined 287 seniors aged from 65 to 74 years in the city of Cruz Alta, state of Rio Grande do Sul, Brazil. The Fonseca Anamnestic Index was used for temporomandibular dysfunction analysis, as well as a structured questionnaire for socioeconomic conditions and an oral health clinical examination. Either Chi-square or Mann-Whitney tests assessed associations between the dependent and independent variables and presented by frequency distribution. Uni- and multivariate analyses were performed to verify the association between temporomandibular dysfunction risk and explanatory variables. For all statistical analyses, a 5% significance level was adopted. RESULTS: The prevalence of temporomandibular dysfunction symptoms was 55.1%. In the final multivariate model, age ≥70 years (RP=0.674; 95% CI: 0.516 - 0.881) showed as a protection factor against temporomandibular dysfunction, and the average of tooth loss (RP=1.022; 95% CI: 1.004 - 1.039) showed as a risk factor for temporomandibular dysfunction in relation to their respective controls. CONCLUSION: The findings of the present study showed a high prevalence of temporomandibular dysfunction symptoms. Age and tooth loss were associated with higher risk of temporomandibular dysfunction. The results suggested the need for improvement in oral health conditions of the elderly and the importance of further epidemiological studies about temporomandibular dysfunction in this population.


RESUMO JUSTIFICATIVA E OBJETIVOS: Avaliar a gravidade dos sintomas de disfunção temporomandibular e seus fatores em idosos de uma cidade do sul do Brasil. MÉTODOS: Estudo observacional transversal de domicílios residenciais, com amostra probabilística por conglomerado, entrevistou e examinou 287 idosos, com idade entre 65 e 74 anos da cidade Cruz Alta, estado do Rio Grande do Sul, Brasil. O Índice Anamnésico de Fonseca foi utilizado para avaliação da disfunção temporomandibular, além de um questionário estruturado para condições socioeconômicas e um exame clínico de saúde bucal. As associações entre a variável dependente e a independente foram avaliadas pelos testes de Qui-quadrado ou Mann-Whitney, apresentadas por meio da distribuição de frequências. As análises uni e multivariada foram realizadas para verificar a associação entre a disfunção temporomandibular e as variáveis exploratórias. Para todas as análises, o nível de significância foi de 5%. RESULTADOS: A prevalência de sintomas de disfunção temporomandibular foi de 55,1%. No modelo multivariado final, a idade ≥70 anos (RP=0,674; 95% IC: 0,516 - 0,881) apresentou-se como fator de proteção para disfunção temporomandibular e a média de perda dentária (RP=1,022; 95% IC: 1,004 - 1,039) apresentou-se como fator de risco para disfunção temporomandibular em relação a seus respectivos controles. CONCLUSÃO: Os resultados demonstraram alta prevalência de sintomas de disfunção temporomandibular. A idade e a média de perda dentária foram associadas à disfunção temporomandibular. Os resultados sugerem melhorias nas condições de saúde bucal dos idosos e a importância de estudos epidemiológicos sobre disfunção temporomandibular nessa população.

ABSTRACT

Aim: This study aimed to correlate stressors with psychological well-being and health factors in dental students from public and private schools. Methods: From February to May 2015, three different instruments (Dental Environment Stress ­ DES ­ Psychological General Well-Being ­ PGWB ­ and SF-36 Health Survey) were applied to students from two public and two private dental schools from the State of Ceará, Brazil. Mann-Whitney test or t test for independent samples were used in order to compare the stressors between private and public dental schools students. Correlations to each DES domain were performed using Kendall's Tau C test. Results: A total of 92 (45.32%) and 111 (56.68%) students from public and private schools, respectively, answered the questionnaire. Students from public schools demonstrated significantly higher scores in DES/academic performance and DES/personal and institutional factors (p<0.05). Significant negative correlations were detected between PGWB/anxiety and PGWB/general with all DES domains for both public and private schools (p<0.05). Additionally, DES/academic performance was significantly correlated with several SF-36 domains, such as physical function, vitality, and social functioning, to both public and private schools (p<0.05). However, DES/academic performance and SF-36/role physical was only significantly correlated in private school students (r=-0.171, p=0.039), while SF-36/bodily pain (r=-0.274, p<0.001), general health (r=-0.245, p=0.001), and mental health (r=-0.286, p<0.001) were significantly correlated with DES/academic performance only in public school students. Conclusion: Students from public and private dental schools presented different stressor patterns. Additionally, most of DES domains were significantly associated with PGWB and SF-36 to both public and private schools

ABSTRACT

Aim: To investigate tooth loss and its determinants in adolescents, considering the effect of extractions due to orthodontics reasons. Methods: This cross-sectional study was performed in students from public and private schools aged 15-19 years old from Passo Fundo, Brazil. The proportional randomly chosen sample included 736 adolescents. Clinical examinations and interviews were performed. Associations between prevalence of tooth loss and exposure variables studied were analysed by Poisson Regression with uni- and multivariate robust variance in two models. One model comprised students who had experienced tooth loss without orthodontic reasons and the other with all of the subjects presenting tooth loss. Results: Prevalence of tooth loss was 21.1% (mean of 0.42). Higher chances for tooth loss were found in the following features: non-whites (PR=1.72; CI95%:1.15-2.60), poorly schooling mothers (PR=2.2; CI95%:0.96-5.02), from public schools (PR=4.16; CI95%:0.98-17.59), smokers (PR=1.91; CI95%:1.15-3.17). Conclusion: Demographic, socioeconomic and behavioural conditions were strongly associated with tooth loss. These associations were more evident when extractions for orthodontic reasons were not included in the analytical models

ABSTRACT

Este relato de caso objetivou descrever as técnicas de preservação e aumento de rebordo alveolar após perda de um implante osseointegrado. Paciente com 54 anos de idade, do sexo feminino, procurou o serviço odontológico da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul, pois um implante instalado há cincos anos na região do dente 25 encontrava-se com mobilidade. Ao exame clínico e radiográfico, constatou-se perda da osseointegração e extensa perda óssea da região vestibular. Realizou-se a remoção do implante, preservação e aumento de rebordo alveolar com enxerto de osso bovino desproteinizado e membrana de colágeno. Além do aumento da densidade óssea da região, observou-se aumento em espessura gengival, o que favoreceu a estética da área. Nove meses após esses procedimentos, um implante do tipo hexágono externo foi instalado. Posteriormente, uma nova prótese foi confeccionada. Concluiu-se que a preservação de rebordo alveolar é uma técnica de fundamental importância para a adequada instalação de implantes osseointegrados, pois favorece aspectos funcionais e estéticos, podendo ser aplicada em casos de perda de implantes e de dentes.


This case report aimed to describe a case of ridge preservation after loss of an osseointegrated implant. A 54 years-old female sought the dental service of the Federal University of Rio Grande do Sul because her implant, installed five years prior the initial exam, in the region of the element 25, presented mobility. Clinical and tomographic exams showed loss of osseointegration and extensive bone loss in the buccal surface. The implant was removed and the ridge preservation and augmentation was performed with deproteinized bovine bone graft and collagen membrane. In addition to the increased bone density in the region, the gingival thickness were increased in the region, favoring the aesthetics. After nine months, an external hexagon implant was installed. Aftwerwards, a new prosthesis was placed. It was concluded that the ridge preservation is extremely important for proper installation of osseointegrated dental implants, providing better functional and aesthetics aspects and can be applicable to cases where dental implants or tooth were lost.

ABSTRACT

Abstract This study aimed to assess the impact of oral health on the quality of life of adolescents. A cross-sectional study was performed with students from public and private schools from Passo Fundo, Brazil. All students were aged between 15 and 19 years old. The proportional random sample consisted of 736 adolescents from 20 schools. A structured questionnaire was applied, and an oral examination was performed, counting the number of teeth. Oral health-related quality of life was assessed by OHIP-14. Associations between quality of life and associated factors were analyzed. The mean OHIP-14 score was 7.25. Age, ethnicity and studying in a public school were associated to the OHIP-14 score. Tooth loss (p=0.79) was not associated with quality of life. Additionally, questions related to appearance, such as whether teeth appearance bothers the adolescent (p=0.68) were not associated with quality of life. Attending a public school (OR=1.63; CI95%: 0.98-2.70) and self-reported halitosis (OR=1.48; CI95%: 1.01-2.16) were strongly associated to higher impact on quality of life. It was concluded that socioeconomic conditions and halitosis were associated to higher impact on quality of life of adolescents


Resumo Esse estudo objetivou verificar o impacto da saúde bucal na qualidade de vida de adolescentes. Um estudo transversal foi realizado com estudantes de escolas públicas e privadas da cidade de Passo Fundo, Brasil. Todos os estudantes tinham idades entre 15 e 19 anos. Uma amostragem proporcional randômica consistiu em 736 adolescentes de 20 escolas. Um questionário estruturado foi aplicado e exames da cavidade oral foram realizados, contando-se o número de dentes presentes. Qualidade de vida associada à saúde bucal foi verificada pelo OHIP-14. Associações entre qualidade de vida e fatores associados foram analisadas. A média do OHIP-14 foi 7,25. Idade, etnia e estudar em escola pública estiveram associados com escores do OHIP-14. Perda dentária (p=0,79) não esteve associada com qualidade de vida. Além disso, questões relacionadas com a aparência, como, por exemplo, se a aparência do dente incomoda o adolescente (p=0,68), não estiveram associadas com qualidade de vida. Frequentar uma escola pública (OR=1,63; IC95%: 0,98 - 2,70) e halitose autorreportada (OR= 1,48; IC95%: 1,01 - 2,16) estiveram fortemente associadas com altos impactos na qualidade de vida. Concluiu-se que condições socioeconômicas e halitose estão associadas com altos impactos na qualidade de vida de adolescentes.

ABSTRACT

Abstract This study aimed to evaluate the anti-plaque and anti-gingivitis effects of two mouthwashes containing cetylpyridinium chloride (CPC), in comparison to negative control mouthwash. One hundred and twenty subjects were randomly assigned to study groups: test (0.075% CPC and 0.28% zinc lactate), positive control (0.07% CPC) and negative control mouthwash without CPC. All volunteers were examined by a calibrated examiner for the Quigley-Hein Plaque Index (Turesky modification) and Löe-Silness Gingival Index (GI). Gingival severity was also measured by the percentage of sites with positive gingival bleeding. During six weeks, oral hygiene consisted of brushing twice daily with a toothbrush and toothpaste and rising with their assigned mouthwash. Plaque and gingival parameters were assessed at baseline, after four and six weeks of product use. Statistical analyses were performed separately for plaque and gingival indices, by ANOVA, paired t-test and ANCOVA (α < 0.05). After 4 and 6 weeks, all mouthwashes groups presented statistically significant reductions in plaque and gingival parameters as compared to baseline. In comparison to the positive control, the test group presented additional reductions in dental plaque of 19.8% and 16.8%, after 4 and 6 weeks, respectively. For GI, the additional reductions in the test group were 9.7% and 14.3%, at 4 and 6 weeks, respectively. The test group showed additional reduction of 35.3% and 54.5% in the gingival severity, at week 4 and 6, respectively. It is concluded that the mouthwash containing CPC and zinc lactate presents significant anti-plaque and anti-gingivitis effects as compared to positive and negative control mouthwashes.

ABSTRACT

ABSTRACT Periodontal diseases are infecto-inflammatory diseases. Literature, has tried to elucidate the infections component of gingivitis and periodontitis, for several years. In recent years, much has been discussed about the role of the host response modulators to periodontal therapeutic procedures. The aim of the present literature review was to evaluate the effect of host response modulating agents (anti-inflammatories) on the pathogenesis of gingivitis and periodontitis. A search in the main databases was performed and human and animal studies were selected. The majority of studies was performed in humans and non-steroidal anti-inflammatory drugs in different dosages were used. The results have shown a potential benefit of the non-steroidal anti-inflammatory drugs concerning the microbial challenge. However, this benefit seems not to occur in the long term, thus not supporting it as a periodontal therapeutic approach. Few studies evaluated the effect of steroidal anti-inflammatory drugs on the pathogenesis of periodontal diseases. Moreover, the results in humans and animals are controversial, pointing to a possible deleterious effect of steroidal anti-inflammatory drugs on periodontal structures.


RESUMO Doenças periodontais são doenças de natureza infecto-inflamatória. A literatura, por muitos anos, preocupou-se em elucidar somente o aspecto infeccioso de gengivites e periodontites. Nos últimos anos, muito tem-se debatido quanto ao papel da modulação da resposta do organismo como medida terapêutica periodontal. Nesse sentido, o objetivo da presente revisão de literatura foi avaliar o efeito de agentes moduladores da resposta inflamatória (antiinflamatórios) na patogênese de gengivites e periodontites. Foi realizada uma busca nas principais bases de dados sendo selecionados estudos em humanos e em modelo animal. Observou-se que a maioria dos estudos foi realizada em humanos e utilizou antiinflamatórios não-esteróides) em diferentes posologias. Os resultados dos estudos apontam para um potencial efeito benéfico dos antiinflamatórios não-esteróides frente ao desafio microbiano. Entretanto, esse benefício parece não ocorrer a longo prazo não sendo justificado seu uso como medida terapêutica periodontal. Poucos estudos avaliaram o efeito dos antiinflamatórios esteróides na patogênese das doenças periodontais. Além disso, os resultados dos estudos tanto em humanos quanto em animais são controversos, mas apontam para um possível efeito deletério dos antiinflamatórios esteróides sobre as estruturas periodontais.

ABSTRACT

O presente estudo analisou a percepção e o nível de conhecimento de estudantes e pacientes sobre halitose. Dois grupos de voluntários de ambos os gêneros, entre 18 e 60 anos, totalizando 225 participantes, responderam a um questionário que continha oito questões relativas à percepção, às causas e ao tratamento da halitose. O grupo de pacientes (P) consistiu-se de 150 indivíduos que procuraram os serviços odontológicos da Faculdade de Farmácia, Odontologia e Enfermagem da Universidade Federal do Ceará, Brasil, e o grupo de estudantes (S), de 75 alunos de Odontologia da mesma Universidade. No grupo P, 45,3% dos participantes acreditava ter halitose, já no grupo S, esse percentual foi de apenas 16,2%. Em relação às causas e aos tratamentos da halitose, encontrou-se que o grupo P assinalou mais opções relacionadas com o correto conhecimento sobre halitose quando comparados com o grupo S. É possível concluir que os pacientes relataram maior percepção da halitose do que os estudantes, bem como têm demonstrado maior conhecimento sobre a origem e tratamento da halitose.


This study aimed to assess individual perception and level of knowledge of students and patients about halitosis. Two groups of volunteers of both genders between 18 and 60 years old, totaling 225 subjects, answered a questionnaire containing eight questions relating to perception, causes, and treatment of halitosis. The group of patients (P) consisted of 150 individuals seeking dental services at the School of Pharmacy, Dentistry and Nursing, Federal University of Ceará, Brazil, and the Group of students (S) consisted of 75 students of Dentistry at the same University. In Group P, 45.3% of participants believed they had halitosis, while in Group S, this percentage was only 16.2%. In matters relating to the causes and treatment of halitosis, it was found that the Group P marked more options related to the correct knowledge about halitosis when compared to Group S. It is possible to conclude that patients reported greater halitosis perception than students, and also that they showed a better knowledge about the halitosis etiology and treatment.

ABSTRACT

Abstract The aim of this study was to compare the efficacy in supragingival plaque removal of two soft-bristle toothbrushes. Seventy volunteers were allocated randomly to the Colgate Slim Soft or Curaprox CS5460 toothbrush grourps. At baseline appointment, volunteers underwent plaque examination using the Rustogi Modification of the Navy Plaque Index. Under supervision, they then brushed their teeth for 1minute with their assigned toothbrushes and the plaque examination was repeated. Volunteers performed daily oral hygiene with their assigned toothbrush and a regular dentifrice provided by the researchers for 7 days. The baseline experimental procedures were then repeated. Separate analyses of variance were performed for the whole-mouth, interproximal, and gumline plaque scores (p < 0.05). No difference in baseline pre-brushing scores was found between groups. After a single toothbrushing, the mean plaque score was significantly reduced in both groups (p < 0.05), with greater reduction of whole-mouth and interproximal plaque scores observed in the SlimSoft group compared with the Curaprox group (p < 0.05). After 7 days, the SlimSoft group showed greater reduction of the whole-mouth and interproximal plaque scores compared with the Curaprox group (p < 0.05). In conclusion, the SlimSoft toothbrush presented greater efficacy in supragingival plaque removal than did the Curaprox CS5460 toothbrush, as reflected by whole-mouth and interproximal plaque scores.

ABSTRACT

Obesidade é o acúmulo excessivo ou anormal de gordura em relação à massa magra, podendo ser modificada por fatores ambientais, genéticos e comportamentais. Na literatura, é bem estabelecida a associação entre diabetes, tabagismo e, mais recentemente, obesidade e periodontite. Entretanto, estudos de prevalência e de associação entre obesidade e gengivite ainda são bastante escassos, especialmente em indivíduos adultos. O presente estudo objetivou verificar a associação entre obesidade e diferentes fatores sociodemográficos, médico-odontológicos e comportamentais em uma amostra de indivíduos adultos da cidade de Porto Alegre, Brasil. Esse estudo, de caráter epidemiológico transversal, avaliou 614 indivíduos maiores de 18 anos. Foram incluídos apenas os indivíduos com pelo menos quatro dentes em boca e que não utilizem aparelhos ortodônticos fixos. Os participantes foram identificados por meio de uma amostragem probabilística multi-estágios, considerando também a distribuição de acordo com o gênero e faixa etária. Dez setores censitários foram visitados. Uma entrevista estruturada foi realizada por pesquisadores treinados, obtendo-se informação de gênero, idade, hábitos comportamentais e estado de saúde sistêmica. Um examinador treinado e calibrado realizou exames de Índice de Placa Visível, Índice gengival de Lõe-Silness, modificado por Lõe, e cálculo. Além disso, peso, altura e percentual de gordura, obtido através de um aparelho portátil de microcorrente elétrica, também foram coletados. Regressão multivariada de Poisson foi utilizada para avaliar a associação entre obesidade e os diferentes fatores médico-odontológicos e sociodemográficos. Dos indivíduos examinados, 33,89% foram classificados como obesos por apresentarem índice de massa corporal pelo menos de 30 kg/m²...


Obesity is the excessive or abnormal accumulation of fat in relation to lean body mass that may be modified by environmental, genetic and behavioral factors. It is well established the relationship between diabetes, smoking and, more recently, obesity and periodontitis. However, studies regarding the association between obesity and gingivitis are quite scarce, especially in adults. This study aimed to verify the association between obesity and different sociodemographic, medical, dental and behavioral factors in a sample of adults in the city of Porto Alegre, Brazil. This is as an epidemiological cross-sectional study that evaluated 614 subjects with at least 18 years old. Only subjects with the minimum of four teeth and those who did not use fixed orthodontic appliances were included. Participants were identified through a multi-stage probability sampling, considering the distribution according to gender and age. Ten census tracts were visited. A structured interview was conducted by trained researchers to collect information about gender, age, behavioral habits and systemic impaired conditions. A trained and calibrated examiner performed the Plaque Visible Index, Lõe-Sillness Gingival Index modified by Lõe and calculus. Additionally, weight, height and body fat percentage, obtained through a portable electrical microcurrent, were collected. Multivariate Poisson regression was used to evaluate the association between obesity and the sociodemographic, medical, dental and behavioral factors. Obesity, defined as body mass index ≥30kg/m2, were found in 33.89% of the examined subjects. It was showed that females, self-reported hypertension, no smoking, higher visible plaque percentage, and bigger number of teeth were significantly associated with obesity compared to non-obese subjects...

ABSTRACT

Apesar do controle mecânico ser tido como o melhor método para remoção do biofilme das superfícies dentárias, a utilização de agentes antimicrobianos presentes em soluções para bochechos e em dentifrícios é, muitas vezes, requerida. O presente estudo teve como objetivo revisar a literatura acerca da composição dos dentifrícios atuais, seus princípios ativos e suas indicações clínicas. Para tanto, revisou-se a literatura compreendida entre o período de 1989 a 2011, utilizando-se a combinação das seguintes palavras-chaves: dentifrícios, composição química e flúor, nas línguas inglesa e portuguesa, nas bases de dados Pubmed, BVS, Bireme, SciELO e Portal da Capes. Foram incluídos também livros-texto de referência. Observou-se que os dentifrícios são utilizados para levar várias substâncias à cavidade bucal, objetivando a redução da cárie, das doenças gengivais e periodontais, do cálculo dentário, da hipersensibilidade dentinária e da halitose. Atualmente, os dentifrícios são compostos por: sistemas abrasivos, detergentes, flavorizantes, solventes, umectantes, aglutinantes, edulcorantes, conservantes e princípio ativo. A variedade de substâncias presentes nos dentifrícios é muito grande, sendo essa uma das razões para a grande dificuldade em identificar o dentifrício mais apropriado para cada situação clínica. No intuito de facilitar a aquisição desses produtos, é de suma importância que a composição química e a sua indicação sejam informadas adequadamente.


Although mechanical control is considered the best method to remove dental surfaces biofilm, the use of antimicrobial agents contained in mouthwashes and toothpaste is required. This study aimed to review the literature about the current composition of dentifrices, their active ingredients and clinical indications. Thus the literature between 1989 and 2011 was reviewed, using the following keyword combinations: dentifrice, chemical composition and fluoride, in English and Portuguese languages, in Pubmed, BVS, Bireme, SciELO, and Portal Capes databases. It was also included reference textbooks. It was observed that dentifrices are used to carry out a lot of substances to oral cavity, aiming to reduce caries, gingival and periodontal diseases, dental calculus, dentin hypersensitivity and also halitosis. Nowadays, dentifrices are composed of: abrasive systems, detergents, flavorings, solvents, humectants, binders, sweeteners, preservatives and active ingredient.The variety of substances found in dentifrices is huge, and this is one of the reasons that makes harder to identify the most appropriate dentifrice for each clinical situation. In order to facilitate the acquisition of these products, is quite important that the chemical composition and its indication are informed properly.
