Abstract: The aim of this cross-sectional study was to evaluate the factors associated with the search by Brazilian and Portuguese dentists for oral health information on social networks during the COVID-19 pandemic. A total of 597 Brazilian and Portuguese dentists answered an online questionnaire between January 17 and 31, 2021. Respondents were asked about sociodemographic data, weight and height, hours of sleep per night, screen time for work and leisure, and where they sought information about general and/or oral health for themselves and for their loved ones and information about COVID-19. Descriptive statistics and binary regression were used for the statistical analysis. Most participants were Brazilian (62.8%) and 451 (75.5%) were female. Mean age was 42.1 years (± 12.5 years). For every lost hour of sleep, the chances of participants frequently or always searching for information about self-perceived oral health problems on lay websites increased by 1.33 times. For every additional hour spent on social networks or on the Internet, the likelihood of participants frequently searching for self-perceived oral health problems on lay websites increased by 17% (OR = 1.17; 95% CI: 1.06-1.30). Individuals who searched the Internet for information about COVID-19 symptoms before consulting their doctors were 3.85 times more likely (95% CI: 2.22-6.67) to frequently or always search for information about self-perceived oral health problems on lay websites. Dentists used lay websites to search for general and oral health knowledge during the COVID-19 pandemic, and shorter sleep duration favored screen use.

Abstract: The aim of the present study was to evaluate the influence of socioeconomic factors, oral conditions and the impact of OHRQoL as possible risk indicators related to the incidence of untreated dental caries in preschool children two years after an initial examination. A prospective longitudinal study was performed with a sample of 288 preschool children allocated to two groups at baseline (T0): caries free (n = 144) and with untreated dental caries (n = 144). Untreated dental caries was determined through clinical examinations performed by a calibrated dentist at T0 (Kappa > 0,89) and T1 (two years after the baseline) (Kappa > 0,91) using the dmft criteria. Parents/caregivers answered a socioeconomic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) at T0 and T1. Mann-Whitney test and hierarchically adjusted Poisson regression models were used (95%CI, p < 0,05). The incidence of untreated dental caries was 41.3%. Low (RR = 1.63; 95%CI:1.18-2.26; p < 0.001) and high severity of untreated dental caries (RR = 1.92; 95%CI:1.36-2.72; p < 0.001), monthly household income less than two times the Brazilian minimum salary (RR = 1.79; 95%CI:1.04-3.25; p = 0.042) and overall B-ECOHIS score (RR = 1.03; 95%CI:1.02-1.05; p < 0.001) at T0 were risk indicators for the incidence of untreated dental caries among the preschool children. In conclusion, the incidence of untreated dental caries was high and the higher severity of untreated dental caries, the lower monthly income and the higher the B-ECOHIS score (indicating a negative impact on quality of life) were risk indicators to the developing of new lesions of untreated dental caries after 2 years.

Abstract: This study evaluated the association between socioeconomic factors and stages of dental caries in children one to five years of age. A cross-sectional study was conducted involving 759 children enrolled in preschools in Diamantina, Brazil. The parents/caregivers filled out a form addressing socioeconomic factors. Add to the end of this sentence: and categorized in caries free (code 0 and 1), no obvious decay (code 2 and 3) and obvious decay (code 4, 5 and 6). Statistical analysis was performed using the Mann-Whitney test and multinomial regression. The prevalence of "no obvious decay" was higher among children from families with a larger number of income-dependent individuals (OR: 2.47; 95%CI: 1.41-4.31). The higher prevalence of "obvious decay" was associated with the child's age (OR: 1.36; 95%CI: 1.16-1.58), attending a public preschool (OR: 2.38; 95%CI: 1.31-4.34), a larger number of income-dependent individuals (four to five individuals: OR: 1.71; 95%CI: 1.09-2.74; more than five individuals: OR: 3.41; 95%CI: 1.95-5.94), no access to a dentist (OR: 2.14; 95%CI: 1.48-3.09), and lower income (OR: 1.72; 95%CI: 1.19--2.49). It was concluded that the variable of a larger number of income-dependent individuals was associated with both no obvious decay and obvious decay. Child's age, type of preschool, access to a dentist, and income were associated with obvious decay.

This study aimedto assess knowledge related to erosive tooth wear (ETW) among patients, students and facultymembersin a Brazilian dental school and compare it with data from a previous studyconducted ten years earlier in the same academic environment. Acontrolled cross-sectional study involving 289 participants was conducted at a dental school in Belo Horizonte, Southeastern Brazil. Knowledge ofETWwasevaluated through a self-administered questionnaire. Statistical analysis usedchi-square test;z-test adjusted by Bonferroni correction(p≤0.05). Ethical approval and informed consent were obtained.Among the 289 participants, 71.0% had heard about ETWwith a lower percentage among patients (p<0.001). Students and faculty members frequently mentioned eating disorders and acidic diet as the main etiological factors for ETW (p<0.001). However, patientsacknowledged bacteria (p=0.026) and poor oral hygiene (p=0.002) as etiological factors.Comparison between present findings and data from the previous studyshowed no significant increase in participants who had heard about the condition (p>0.499). There was also no improvement in knowledge of ETW among patients(p>0.227), andno significant difference when patients were asked whether they had received preventive recommendations by students (p=0.303).However, there was a significant improvement in all variables regarding students' diagnostic skills (p<0.005) and in the knowledgeof ETW signs and symptoms among faculty members (p=0.030).In conclusion, knowledge of ETW is still not fully incorporated by the sample. However, there was an improvement in students and faculty's diagnostic skillssince the last study conducted in 2010 (AU).

Este estudo teve como objetivo avaliar o conhecimento relacionado ao desgaste dentário erosivo entre pacientes, alunos e docentes deuma faculdade de odontologia brasileira,e compará-lo com um estudo anterior, realizado dez anos antes, no mesmo ambiente acadêmico. Trata-se de um estudo transversal controlado,envolvendo 289 participantes,que foi realizado em uma faculdade de odontologia em Belo Horizonte, sudeste do Brasil. O conhecimento do desgaste erosivo foi avaliado por um questionário autoaplicável. A análise estatística utilizou o teste qui-quadrado e teste Z ajustado pela correção de Bonferroni (p<0,05). Aprovação ética e consentimento informado foram obtidos. Dentre os 289 participantes, 71,0% já ouviram falar sobre o desgaste dentário erosivo,com menor percentual entre os pacientes (p<0,001). Alunos e docentes frequentemente mencionaram transtornos alimentares e dieta ácida como os principais fatores etiológicos para o desgaste erosivo (p<0,001).No entanto, os pacientes relataram bactérias (p=0,026) e má higiene bucal (p=0,002) como fatores etiológicos. A comparação entre os resultados atuais e oestudo anterior não mostrou aumento significativo quantoaos participantes que tinham ouvido falar sobre a essa implicação dentária (p>0,499). Tambémnão houve melhora no conhecimento do desgaste erosivo entre os pacientes (p>0,227), e nenhuma diferença significativa quando elesforam questionados se haviam recebido recomendações preventivas dos alunos (p=0,303). No entanto, houve uma melhora significativa em todas as variáveis em relação às habilidades diagnósticas dos alunos (p<0,005) e no conhecimento dos sinais e sintomas do desgaste erosivo entre os docentes (p=0,030). Em conclusão, o conhecimento do desgaste dentário erosivo ainda não está totalmente incorporado pela amostra. No entanto, houve uma melhoria nas habilidades de diagnóstico dos alunos e docentesdesde o último estudo,realizado em 2010 (AU).

Abstract The objective was assess the influence of untreated caries and socioeconomic status (SES) on school dropout among adolescents. A six-year cohort study was conducted with random sample of adolescents (12 years-old) who had been evaluated initially in 2012 from Santa Maria, Brazil. Sex, socioeconomic status (mother's education and household income), and untreated caries were collected at the baseline. The outcome variable was collected at the follow-up through self-report and was divided into three categories: adolescents who only studied, who studied and employed, and who school dropouts. A multinomial regression model was performed to assess the influence of oral disease and SES on school leaving, through relative risk ratio (RRR) and 95% confidence interval (95% CI). From of 1,134 adolescents evaluated at the baseline, 768 participants with a mean age of 17.5 years were re-evaluated at follow-up (67.8% response rate). Male (RRR: 2.31; 95%CI: 1.19-4.48) and adolescents with untreated caries at the baseline had an increment in school-leaving (RRR: 2.26; 95%CI: 1.12-4.56). Mothers with low education (RRR: 2.24; 95%CI: 1.09-4.61) had a higher probability of having children who leave school. Untreated caries and low SES in early adolescence can influence the tendency to school dropouts.

Resumo O objetivo foi avaliar a influência da cárie dentária não tratada e do status socioeconômico (SES) sobre o abandono escolar dos adolescentes. Foi realizado um estudo de coorte de seis anos de acompanhamento com uma amostra aleatória de adolescentes (12 anos de idade) avaliados inicialmente em 2012 em Santa Maria, Brasil. Sexo, status socioeconômico (educação da mãe e renda familiar) e cárie não tratada foram coletados no início do estudo. A variável de desfecho foi coletada no acompanhamento por meio do autorrelato e foi dividida em três categorias: adolescentes que apenas estudavam, aqueles que estudavam e trabalhavam e quem tinha abandonado a escola. Um modelo de regressão multinomial foi realizado para avaliar a influência da doença bucal e do SES sobre o abandono escolar, por meio da razão de risco relativo (RRR) e intervalo de confiança de 95% (IC95%). Dos 1.134 adolescentes avaliados no início do estudo, 768 participantes com idade média de 17,5 anos foram reavaliados no acompanhamento (taxa de resposta de 67,8%). Meninos (RRR: 2,31; IC 95%: 1,19- 4,48) e adolescentes com cárie não tratada no início do estudo tiveram um incremento no abandono escolar (RRR: 2,26; IC 95%: 1,12-4,56). Mães com baixa escolaridade (RRR: 2,24; IC95%: 1,09-4,61) tiveram maior probabilidade de ter filhos que abandonaram a escola. Cárie dentária não tratada e baixo SES no início da adolescência pode influenciar a tendência de evasão escolar.

Introdução: O possível bruxismo é um comportamento autorrelatado, caracterizado pelo ranger e/ou apertar dos dentes, estando associado a fatores psicológicos. A pandemia da COVID-19 tem afetado o emocional das pessoas, podendo ser associada a este comportamento. Objetivo: Analisar a associação entre o nível de medo da COVID-19, assim como outros fatores associados à prevalência de possível bruxismo entre universitários. Materiais e métodos: Participaram deste estudo transversal 311 universitários de graduação e pós-graduação de faculdades odontológicas públicas e privadas da região sudeste do Brasil. Os participantes foram contatados via WhatsApp e redes sociais através de amostragem em bola de neve para responder um questionário com avaliação sociodemográfica, presença, frequência e severidade de possível bruxismo do sono (PBS) e/ou em vigília (PBV) e a versão brasileira da fear scale of COVID-19. Análises descritivas e bivariadas foram realizadas através dos testes estatísticos de Mann-Whitney e Kruskall-Wallis (p<0,05). Resultados: A prevalência de PBS grave foi de 12,5% e PBV 23,8%. Não houve associação entre escores de medo COVID-19 nem com PBS (p=0,342) nem com PBV (p=0,912). Quando analisado o PBV, observou-se maior prevalência dentre os participantes que não trabalhavam (p=0,008), sendo maior percentual entre os universitários na segunda metade do curso (p=0,021) e, dentre os participantes da pós-graduação, o bruxismo foi mais prevalente entre alunos matriculados em programas stricto sensu comparados àqueles de programas lato sensu (p=0,036). Conclusão: Estar fora do mercado de trabalho, a fase final da graduação e a inserção em uma pós-graduação stricto sensu influenciaram na prevalência de PBV.

Introduction: The possible bruxism is a self-reported behavior characterized by grinding and/or clenching teeth and is associated with psychological factors. The COVID-19 pandemic has affected people's emotions and can be associated with this behavior. Objective: Analyze the association between level of fear of COVID-19, as well as other factors associated to the prevalence of possible bruxism among university students. Materials and methods: A total of 311 undergraduate and graduate students from public and private dental schools in Southeastern Brazil participated in this cross-sectional study. Participants were contacted via WhatsApp and social networks through snowball sampling to answer an online questionnaire with sociodemographic assessment, presence, frequency and severity of possible sleep bruxism (PSB) and/or awake bruxism (PAB) and Brazilian version of the fear scale of COVID-19. Descriptive and bivariate analyzes were performed using the Mann-Whitney and Kruskall-Wallis statistical tests (p<0.05). Results: The prevalence of severe PSB was 12.5% and PAB 23.8%. There was no association between COVID-19 fear scores or with PSB (p=0.342) or with PAB (p=0.912). When analyzing the PAB, there was a higher prevalence among participants who didn't work (p=0.008), with a higher percentage among university students in the second half of the course (p=0.021). Among graduate participants, possible bruxism was more prevalent among students enrolled in stricto sensu programs compared to those in lato sensu programs (p=0.036). There wasn't association between COVID-19 fear score and possible bruxism. Conclusion: Being out of the job market, final stage of graduation and entry into a stricto sensu graduate program influenced the prevalence of PAB.

ABSTRACT Objective: To evaluate the influence of oral health clinical and non-clinical indicators on adolescents' academic performance. Material and Methods: A longitudinal design was performed with a random sample of 1,134 12-year-old Brazilian adolescents. In 2012, the adolescents were clinically assessed by calibrated dentists and investigated about demographics, socioeconomic factors, dental service use, toothache, and verbal bullying related to oral condition via structured questionnaires. The contextual variable was obtained from the city's official database. After two years, 771 adolescents were reassessed. The outcome adolescent's academic performance (good or poor) was collected through official school's register. Multilevel logistic regression analyses were performed to assess associated factors for adolescents' academic performance. Results: Adolescents with toothache (OR 1.74; CI 95%: 1.05-2.89), who have been a victim of bullying (OR 2.23; CI 95%: 1.21-4.09), and were male (OR 1.92; CI 95%: 1.19-3.09) had a lower academic performance. On the other hand, adolescents whose mothers had higher educational levels (OR 1.79; CI 95%: 1.08-2.97) and belonged to higher-income households (OR 1.95; CI 95%: 1.18-3.23) had higher academic performance when compared to their peers. Conclusion: Adverse oral conditions, as well as subjective and socioeconomic factors, impacted on adolescents' academic performance.

Abstract Mucopolysaccharidosis (MPS) is a group of rare and inherited metabolic disorders caused by the accumulation of macromolecule glycosaminoglycans inside lysosomes. Affected individuals may have dental and craniofacial tissue alterations, facilitating the development of several oral diseases. Objectives To assess, with panoramic radiographic images, the frequency of dental and maxillomandibular incidental findings among MPS individuals and compare them with non-MPS individuals. Methodology A cross-sectional study evaluating a sample of 14 MPS individuals and 28 non-MPS individuals aged from 5 to 26 years was carried out. They were matched for sex and age on a 2:1 proportion. Panoramic radiographs were assessed for the presence/absence of the following dental and maxillomandibular alterations: dental anomalies of number (hypodontia/dental agenesis, supernumerary teeth); anomalies of form (microdontia, macrodontia, conoid teeth, taurodontism, and root dilaceration); anomalies of position (impacted tooth, inverted tooth, tooth migration, partially bony teeth, complete bony teeth); periapical alterations (furcation lesion, circumscribed bone rarefaction); other alterations (radiolucent bone lesions, radiopaque bone lesions, radiopacity in the maxillary sinus, condylar hypoplasia). Differences between groups were tested by the Fisher's exact test and chi-square test (p<0.05). Results For intrarater agreement, Kappa values were 0.76 to 0.85. The presence of supernumerary teeth (p=0.003); conoid teeth (p=0.009); taurodontism (p<0.001); impacted teeth (p<0.001); partial bony teeth (p=0.040); complete bony teeth (p=0.013); and root dilaceration (p=0.047) were statistically more frequent in MPS individuals compared to non-MPS individuals. Bone rarefaction/furcation lesions (p=0.032), condylar hypoplasia (p<0.001), radiolucent bone lesions (p=0.001), and dentigerous cysts (p=0.002) were also more frequent in MPS individuals. Conclusion The presence of specific oral manifestations is more common in MPS individuals than non-MPS individuals.

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

Abstract This study aimed to describe different approaches for the evaluation of the Oral health-related quality of life (OHRQoL) of preschool children and to discuss perspectives for future instruments. The OHRQoL is a concept that surpasses an exclusively clinical perception and includes functional, social, emotional, and environmental issues. The measure of OHRQoL represents a holistic approach for researchers and clinicians extending their visions beyond the mouth and understanding the entire context of the patient. Negative impacts of oral conditions on OHRQoL in childhood can reflect on health development, especially in a life stage marked by social and cognitive maturation. Instruments have been developed and cross-culturally adapted to evaluate the impact of oral conditions on the OHRQoL of preschool children and their families. Some features distinguish these instruments and influence their selection, such as: self- or proxy-report; generic- or specific-condition; long- or short-form, and less or more established used in literature. Moreover, theoretical framework, construct validation and availability should also be considered. Nine OHRQoL instruments for preschool children were included in the present literature review. They were created between 2003 and 2017 by developed countries in most cases. The shorter instrument has five items, and the larger has 31 items. Most of them are proxy-reported, generic-condition, and have been relatively well established in the literature. The diversity of instruments indicates the evolution of OHRQoL studies, but there are methodological issues still in need to be improved in future developments or cross-cultural adaptations, according to current psychometric evidence.

Resumo Qualidade de Vida Relacionada à Saúde Bucal (QVRSB) é um conceito que extrapola uma percepção exclusivamente clínica ao incluir questões funcionais, sociais, emocionais e ambientais. A avaliação da QVRSB representa uma abordagem holística para a pesquisa e prática clínica. O impacto negativo das condições bucais na QVRSB durante a infância pode refletir no desenvolvimento saudável, especialmente em um estágio da vida marcado pela maturação social e cognitiva. Instrumentos vêm sendo desenvolvidos e adaptados transculturalmente para avaliar o impacto das condições bucais na QVRSB de pré-escolares e seus familiares. Algumas características distinguem esses instrumentos e influenciam na seleção, tais como: autorrelato ou relato proxy; condição genérica ou específica; formas longas ou curtas, mais ou menos estabelecidos na literatura. Além disso, a base teórica, a avaliação do construto e a disponibilidade do instrumento também devem ser consideradas. A diversidade de instrumentos indica a evolução dos estudos em QVRSB, mas ainda há questões metodológicas que precisam ser avançadas em futuros desenvolvimentos ou adaptações desses instrumentos, seguindo as atuais evidências psicométricas. O presente estudo objetiva descrever as diferentes abordagens para avaliar a QVRSB de pré-escolares e discutir as perspectivas para futuros instrumentos.

Objetivo: Traçar o perfil dos orientadores de Iniciação Científica da Faculdade de Odontologia da Universidade Federal de Minas Gerais durante uma década.Métodos: Foi feita uma avaliação retrospectiva da formação, da carreira e daexperiência de orientações na pós-graduação e na graduação dos professores da Instituição que orientaram alunos como bolsistas do Programa de Iniciação Científica de 2006 a 2016. Com base em informações dos currículos cadastrados na plataforma Lattes do CNPq, a produção intelectual dos docentes foi analisada, quanti e qualitativamente, Qualis 2015. Para avaliar a correlação entre o número de orientações de Iniciação Cientifica e as demais variáveis numéricas, foi usado o coeficiente de correlação de Spearman e para verificar se existia diferença entre o número de orientações de Iniciação Cientifica entre as categorias das variáveis categóricas, foram usados os testes de Mann-Whitney e Kruskal-Wallis. Resultados: Pouco mais de 35% (n = 44) do total de professores da Instituição, com formações, tempo de titulação e níveis de carreira diversos, alocados nos 4 departamentos, orientaram bolsistas no período; dos quais 18 tinham orientações em andamento. Quase 90% destes apresentam vínculo com Programa de pós-graduação. As áreas responsáveis pelo maior número de bolsas vigentes são a Odontopediatria e Odontologia social e preventivas. O número de orientações de Iniciação Científica concluídas e em andamento por orientador apresentou correlação positiva e significante (rs, p < 0,05) com a produção científica qualificada (≥ B3) e com o número de orientações de pós-graduação stricto sensu, mas não esteve correlacionada a outras produções e orientações. Conclusão: O perfil de orientadores de Iniciação Científica entre o período de 2006-2016 foi diversificado, com diferentes áreas de atuação, níveis de carreira e titulação. No entanto, observamos que a participação no Programa é pequena diante do total de docentes com titulação, capacidade de orientação e do número de alunos de graduação da Instituição. Isso se deve principalmente ao número de bolsas de Iniciação Científica não conseguir contemplar todos os professores que se inscrevem no programa.

Aim: To outline the profile of the Scientific Initiation advisors of the School of Dentistry at the Federal University of Minas Gerais over a 10-year period. Methods: A retrospective assessment was made regarding the education, career, and experience of postgraduate and undergraduate guidance rendered by the institution's faculty who advised students who were fellows of the Scientific Initiation Program from 2006 to 2016. Based on information from registered curricula in the CNPq Lattes platform, the intellectual production of teachers was analyzed, both quantitatively and qualitatively, according to Qualis 2015. To evaluate the correlation between the amount of Scientific Initiation guidance rendered and the other numerical variables, the Spearman correlation coefficient was used, and to verify if there was a difference between the amount of Scientific Initiation guidance rendered between the categories of categorical variables, the Mann-Whitney and Kruskal-Wallis tests were used. Results: Just over 35% (n = 44) of the total number of teachers of the institution, with different degrees, tenure, and career levels, allocated in the four departments, advised fellows during this period, of which 18 received ongoing guidance, almost 90% of which were linked to the Postgraduate Program. The areas responsible for the largest number of scholarships in effect cane from the fields of Pediatric Dentistry and Social and Preventive Dentistry. The amount of completed and ongoing Scientific Initiation guidance rendered per advisor showed a significant positive correlation (rs, p < 0.05) with qualified scientific output (≥ B3) and with the amount of stricto sensu postgraduate guidance rendered, but was not correlated with other productions and advice. Conclusion: The profile of Scientific Initiation advisors between 2006-2016 was diverse, with different areas of activity, career levels, and titles. However, we observed that participation in the program is minimal, given the total number of professors with a degree, capacity to provide advice, and the number of undergraduate students registered at the institution. This is mainly due to the number of Scientific Initiation scholarships failing to contemplate all teachers who enrolled in the program.

Abstract Objective: To analyze the difference of socioeconomic factors among mothers of preterm and full-term infants. Material and Methods: A cross-sectional retrospective study was developed with 250 mothers of children aged three to five years. The sample was divided into two groups: 125 mothers of preterm infants from the referral center of a public hospital in the city of Belo Horizonte, Brazil and 125 mothers of children born full-term at a daycare center within the same city. A pre-tested questionnaire was used to collect socioeconomic data and type of breastfeeding. To verify if there was association between the dependent variable gestational age at birth and the independent variables, the chi-square test was used. A final model with multiple Poisson regression estimated prevalence ratio values for each independent variable was developed. Results: The final multiple regression model showed that mothers that have a low monthly income of up to USD 450.28 (PR = 1.979, 95% CI = 1.082-3.620), used drugs, cigarettes, or alcohol during their pregnancy (PR = 4.095, 95% CI = 2.422-6.921), and did not breastfeed (PR = 2.294, 95% CI = 1.205-4.369) were more likely to give birth to preterm infants. Conclusion: Low monthly family income, use of drugs, alcohol, or smoking during pregnancy and absence of breastfeeding were more frequent on mothers of preterm infants.

Abstract Recently, there has been greater interest in adopting a more holistic approach to healthcare. However, this trend should not limit itself merely to the notion that a human being lies behind the mouth being treated. Rather, it should embrace the understanding that this human can actively participate in and contribute to the treatment process. Patient Report Outcome Measures (PROMs) and Patient Report Experience Measures (PREMs) provide means for measuring data from the patient's perspective, and enable health-related feelings and functions to be evaluated. Accordingly, this critical review aims to provide definitions, rationales and applications of patient-centered approaches in dental clinical research. Some patient-centered constructs are especially relevant to dental clinical trials, such as oral health-related quality of life, pain/discomfort, aesthetics and satisfaction concerning treatment and services. The selection and application of patient-reported measures can vary according to condition (generic, disease-specific or treatment-specific) and to the specific population evaluated (age and cognitive impairment). These measures can help weigh risks and benefits, as well as assess the cost effectiveness of treatments, thus influencing treatment recommendations and health policies. The incorporation of these measures into a professional's daily life not only represents an improvement in professional performance, but also addresses a humanitarian concern.

Abstract The purpose of the present study was to compare the perceptions of the parents/ caregivers of young people with and without Mucopolysaccharidosis (MPS) with regards to their oral health-related quality of life (OHRQoL). A cross-sectional study was conducted with 29 individuals with MPS and 29 normotypic individuals aged three to 21 years and their parents/caregivers. All parents/caregivers of young people with MPS in follow-up at two reference hospitals in the city of Belo Horizonte, southeastern Brazil, were invited to participate in the study. Individuals without MPS were recruited from the pediatric clinics of both hospitals. Parents/caregivers answered a structured questionnaire addressing the sociodemographic characteristics, behavioral habits and medical and dental history of the children as well as the Brazilian short-form version of the Parental-Caregiver (P-CPQ). The individuals with and without MPS were examined for malocclusion, dental caries and oral hygiene by an examiner who had undergone training and calibration exercises. Mean age of the subjects was 12.1 years (± 4.2). Comparing total P-CPQ scores and scores on the oral symptoms, functional limitations and wellbeing domains, the parents/caregivers individuos with MPS reported a statistically significant greater negative impact on OS domain than their counterparts. Regarding the clinical variables, malocclusion was also associated a greater negative impact on OHRQoL of young people with MPS when compared to those of young people without MPS. Our findings show the great negative impact caused by the malocclusion of young people with MPS.

Abstract Recent new zoonotic respiratory viruses have infected humans and led to severe acute respiratory syndrome: severe acute respiratory syndrome coronavirus (SARS-CoV), influenza A H5N1, influenza A H1N1 and Middle East respiratory syndrome coronavirus (MERS-CoV). The first SARS-CoV outbreak took place in 2003, in Guangdong, China. A decade later, another pathogenic coronavirus, MERS-CoV caused an endemic in Middle Eastern countries. The latest pandemic coronavirus infectious disease (COVID-19) has been related to the newly isolated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For the first time since the acquired immunodeficiency syndrome (AIDS) in the 1980s. Dentistry is facing a new turning point. This critical review aims to discuss the impact of COVID-19 infection on oral health care. In dental practice COVID-19 patients are the main source of infection and symptomatic patients are more contagious. Dentists can be first line of diagnosis of the disease, as they work in close contact with patients and are at the risk of being affected by COVID-19 and all respiratory infections. Several guidelines for dental practice environments have been published by dental associations and regulatory boards. It is already evident that biological, psychological and social effects of the COVID-19 pandemic have present and future impacts on dental practice. Dental schools, regulatory boards, scientific associations, government authorities, and public and private health care services must join efforts to design enduring answers for severe and long-standing viral challenges.

Our study sought to evaluate the prevalence of binge drinking in adolescents and its association with density of alcohol outlets around schools. This cross-sectional study was conducted in Belo Horizonte, Minas Gerais State, Brazil, with 436 high-school students aged between 17 and 19 and enrolled in 18 public and private schools. The students completed the Alcohol Use Disorder Identification Test (AUDIT-C), consisting of questions about alcohol consumption by parents and siblings, and socioeconomic status (type of school, mother's education level). Data from geographic information systems were used to estimate the density of alcohol outlets around schools participating. The association between exploratory variables and binge drinking was investigated using multilevel logistic regression analysis (p < 0.05) with random intercepts and fixed slopes. A three-step sequential modeling strategy was adopted. The prevalence of binge drinking was 39.9%. The alcohol consumption among adolescents was lower for those studying in areas with low density of alcohol outlets around schools (OR = 0.32; 95%CI: 0.14; 0.73) and the consumption of alcohol by mothers was associated with binge drinking among adolescents (OR = 1.94; 95%CI: 1.14; 3.30). Our study concluded that binge drinking among adolescents was associated with density of alcohol outlets around the schools and mother's alcohol consumption.

O estudo teve como objetivo avaliar a prevalência de consumo excessivo episódico de álcool entre adolescentes e a associação com a densidade de locais de venda de bebidas alcoólicas no entorno das escolas. Um estudo transversal foi realizado em Belo Horizonte, Minas Gerais, Brasil, com 436 estudantes de segundo grau entre 17 e 19 anos de idade matriculados em 18 escolas públicas e privadas. Os estudantes responderam perguntas do Alcohol Use Disorder Identification Test (AUDIT-C) sobre consumo de álcool pelos pais e irmãos, além de características socioeconômicas (tipo de escola, escolaridade materna). Foram utilizados dados de sistemas de informações geográficas para calcular a densidade de locais de venda de bebidas alcoólicas em torno das escolas participantes. A associação entre variáveis independentes e consumo excessivo episódico de álcool foi investigada por análise de regressão logística multivariada (p < 0,05) com interceptos randômicos e inclinações fixas. Foi adotada uma estratégia de modelagem sequencial em três passos. A prevalência de consumo excessivo episódico de álcool foi de 39,9%. O consumo de álcool entre adolescentes foi mais baixo naqueles que estudavam em áreas com baixa densidade de locais de venda de bebidas alcoólicas em torno das escolas (OR = 0,32; IC95%: 0,14; 0,73), e o consumo de álcool pelas mães esteve associado ao consumo excessivo episódico de álcool pelos adolescentes (OR = 1,94; IC95%: 1,14; 3,30), Em conclusão, consumo excessivo episódico de álcool por adolescentes mostrou associação com a densidade de locais de venda de bebidas alcoólicas no entorno das escolas e com o consumo materno de álcool.

El objetivo de este estudio fue evaluar la prevalencia del consumo compulsivo de alcohol por parte de adolescentes y su asociación con la densidad de establecimientos de venta de alcohol próximos a escuelas. Este estudio transversal se realizó en Belo Horizonte, Minas Gerais, Brasil, con 436 estudiantes de escuelas secundarias con edades comprendidas entre los 17-19 años, inscritos en 18 escuelas públicas y privadas. Los estudiantes completaron con Alcohol Use Disorder Identification Test (AUDIT-C) preguntas sobre el consumo de alcohol por parte de padres y hermanos, así como de su estatus socioeconómico (tipo de escuela, nivel de escolarización de la madre). Los datos del sistema de informaciones geográficas se usaron para calcular la densidad de establecimientos de venta de alcohol en los alrededores de las escuelas participantes. La asociación entre las variables exploratorias y el consumo compulsivo de alcohol fue investigado usando un análisis de regresión logística multinivel (p < 0,05) con intersecciones aleatorias y curvas fijas. Se adoptó una estrategia de modelado secuencial en tres pasos. La prevalencia de consumo compulsivo de alcohol fue de 39,9%. El consumo de alcohol entre adolescentes fue más bajo entre quienes estudiaban en áreas con baja densidad de establecimientos de venta de alcohol alrededor de las escuelas (OR = 0,32; IC95%: 0,14; 0,73), además el consumo de alcohol en madres estuvo asociado con el consumo de alcohol en adolescentes (OR = 1,94; IC95%: 1,14; 3,30). La conclusión fue que el consumo compulsivo de alcohol en adolescentes estaba asociado con la densidad de establecimientos de venta de alcohol en los alrededores de las escuelas y el consumo de alcohol por parte de la madre.

Objetivo: este estudo transversal multicêntrico objetivou determinar a proporção de cárie dentária, sua gravidade e atividade em escolares brasileiros e argentinos. Métodos: a amostra foi composta por escolares selecionados por conveniência, 406 do Brasil (Belo Horizonte - MG) e 241 da Argentina (Córdoba-Cba). Os dados foram coletados por seis dentistas previamente treinados e calibrados (kappaintra≥0,63; kappainter≥0,67). A proporção e gravidade da cárie foram medidas pelos índices ceod e CPOD. A alta experiência de cárie foi identificada pelo Significant Caries Index (SiC). A atividade de cárie foi avaliada segundo a reflexão e a textura da superfície (Nyvad et al., 1999) e o Índice de Cuidados (O/CPO*100) foi mensurado. Resultados: a proporção de livres de cárie (ceod e CPOD = 0) no Brasil foi de 45,7% e 19,9% na Argentina. O ceod foi de 1,48 (IC95%: 1,26-1,71) e 2,38 (IC95%: 2,0-2,72) entre escolares do Brasil e da Argentina, respectivamente. Nos dois países, o componente cariado foi o mais frequente. Entre os indivíduos com experiência de cárie (ceod > 1 e/ou CPOD > 1), a atividade de cárie esteve presente em 77,5% das crianças examinadas no Brasil e em 26,4% na Argentina. No grupo SiC, o CPOD foi de 2,20 (IC95%: 1,95-2,20) no Brasil e 2,17 (IC95%: 1,91-2,43) na Argentina, e o ceod no Brasil foi de 3,37 (3,01-3,72) e na Argentina 5,56 (5,04-6,07). O Índice de Cuidados foi baixo. Conclusão: em ambos os países, a proporção de crianças com experiência de cárie foi alta. Concentração de carga e atividade de cárie foi encontrada em grupos de polarização. Cabe ressaltar que a cárie dentária na dentição decídua é um problema relevante que necessita de esforços direcionados em ambos os países.

Objective: This multicentric cross-sectional study aimed to determine the proportion of dental caries, its' severity and activity among Brazilian and Argentines schoolchildren. Methods: The sample was selected by convenience and comprised of 406 schoolchildren from Brazil (Belo Horizonte-MG) and 241 in Argentina (Córdoba-Cba). Data were collected by six previously trained and calibrated dentists (kappaintra≥0.63; kappainter≥0.67). The proportion and severity of dental caries were measured by dmft and DMFT index. The high caries experiences was identified using Significant Caries Index (SiC). The caries activity was evaluated according to the reflection and texture of the surface (Nyvad et al., 1999) and the Care Index (O/CPO * 100) was measured. Results: The caries free (dmft and DMFT = 0) in Brazil was 45.7% and 19.9% in Argentina. The dmft was 1.48 (95% CI: 1.26-1.71) and 2.38 (95% CI: 2.0-2.72) among schoolchildren in Brazil and Argentina, respectively. In both countries, decayed component was the most frequent observed. Among subjects with caries experience (dmft > 1 and / or DMFT > 1) the caries activity was present in 77.5% of the children examined in Brazil and 26.4% in Argentina. In SiC group, DMFT was 2.20 (95% CI: 1.95-2.20) in Brazil and 2.17 (95% CI: 1.91-2.43) in Argentina and dmft in Brazil was 3.37 (3.01-3.72) and in Argentina was 5.56 (5.04-6.07). The Care Index was low. Conclusions: In both countries, the proportion of children with caries experience was high. Concentration of burden and caries activity was found in polarization' groups. It is noteworthy that caries in the primary dentition is a relevant problem that needs targeted efforts in both countries.

Objective: To evaluate the prevalence of self-reported awake and sleep bruxism and its association to sleep characteristics among dental students. Methods: A cross-sectional study was conducted with 153 students of a Brazilian Dental School. Students who accepted to participate answered a questionnaire evaluating their sex, age, place of living, paid work, nocturnal paid work, hours of sleep per night, time to fall asleep, sleep quality, if participant had a bedroom partner, if participant is quiet on bed while sleeping and intake of sleep medication. Information on intake of energy drink, if participant wake up overnight, if participant wake up tired and it has been difficult to concentrate on daily activities was also collected. Awake and sleep bruxism was based on self-report. Descriptive analysis and chi-square test were carried out. Results: Most students were female (73%) and mean age was 21 years old (±3.25). The prevalence of self-reported awake and sleep bruxism was 36.5% and 11.3%, respectively. Most participants rated their sleep quality as good (57.2%) and reported that they woke up feeling tired (52.6%). Intake of sleep medication in the last 30 days (P=0.002), waking up overnight and taking over an hour to sleep again in the last 30 days (P=0.005) and waking up feeling tired (p=0.012) were associated factors to self-reported awake bruxism. Conclusion: The prevalence of self-reported awake bruxism was higher than the prevalence of sleep bruxism among dental students. Intake of sleep medication, waking up overnight and taking over an hour to sleep again and waking up tired were can be indicators of the presence of awake bruxism in dental students.

Objetivo: Avaliar a prevalência de bruxismo em vigília e do sono e sua associação com características do sono em estudantes de odontologia. Métodos: Ao todo 153 estudantes de uma Faculdade de Odontologia brasileira foram convidados a participar desse estudo transversal, respondendo a um questionário avaliando sexo, idade, endereço, realização de trabalho remunerado e/ou trabalho noturno remunerado, horas de sono por noite, tempo para adormecer, qualidade do sono, sono agitado e a presença de um colega de quarto. A ingestão de bebida energética e pílulas para dormir, o histórico de acordar durante a noite, acordar sentindo-se cansado e dificuldades de concentração nas atividades diárias também foram avaliadas. O diagnóstico de bruxismo baseou-se no auto-relato. Foi realizada a análise descritiva e teste qui-quadrado. Resultados: A média de idade dos participantes foi de 21 anos (±3,25) e 73% eram do sexo feminino. A prevalência do bruxismo em vigília foi de 36,8% e bruxismo do sono foi de 11,3%. A maioria dos participantes, 57,2%, classificou a qualidade do sono como boa, porém 52,6% relataram que acordavam cansados. O uso de medicamento para dormir nos últimos 30 dias (P=0.002), acordar durante a noite e demorar mais de uma hora para dormir novamente nos últimos 30 dias (P=0.005) e acordar sentindo-se cansado (P=0.012) foram fatores associados ao bruxismo em vigília auto-relatado. Conclusão: A prevalência de bruxismo em vigília foi maior que a prevalência do bruxismo do sono em estudantes de odontologia. O uso de medicamento para dormir, acordar durante a noite e demorar mais de uma hora para dormir e acordar sentindo-se cansado podem ser fatores indicadores da presença de bruxismo em vigília em estudantes de odontologia.

Abstract In the last decades, several instruments have been used to evaluate the impact of oral health problems on the oral health-related quality of life (OHRQoL) of individuals. However, some instruments lack thorough methodological validation or present conceptual differences that hinder comparisons with instruments. Thus, it can be difficult to clinicians and researchers to select a questionnaire that accurately reflect what are really meaningful to individuals. This short communication aimed to discuss the importance of use an appropriate checklist to select an instrument with a good methodological quality. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was developed to provide tools for evidence-based instrument selection. The COSMIN checklist comprises ten boxes that evaluate whether a study meets the standard for good methodological quality and two additional boxes to meet studies that use the Item Response Theory method and general requirements for results generalization, resulting in four steps to be followed. In this way, it is required at least some expertise in psychometrics or clinimetrics to a wide-ranging use of this checklist. The COSMIN applications include its use to ensure the standardization of cross-cultural adaptations and safer comparisons between measurement studies and evaluation of methodological quality of systematic reviews of measurement properties. Also, it can be used by students when training about measurement properties and by editors and reviewers when revising manuscripts on this topic. The popularization of COSMIN checklist is therefore necessary to improve the selection and evaluation of health measurement instruments.

Resumo Nas últimas décadas, vários instrumentos tem sido utilizados para avaliar o impacto dos problemas de saúde bucal na qualidade de vida relacionada à saúde bucal (OHRQoL) dos indivíduos. No entanto, alguns instrumentos não possuem validação metodológica completa ou apresentam diferenças conceituais que dificultam as comparações com instrumentos. Assim, pode ser difícil para clínicos e pesquisadores selecionar um questionário que reflita com precisão o que é realmente significativo para os indivíduos. Esta comunicação rápida teve como objetivo discutir a importância de usar um checklist apropriado para selecionar um instrumento com boa qualidade metodológica. O COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist foi desenvolvido para fornecer ferramentas para a seleção de instrumentos baseados em evidências. O COSMIN checklist compreende dez quadros que avaliam se um estudo atende o padrão para uma boa qualidade metodológica e dois quadros adicionais para atender a estudos que usam o método Item Response Theory e os requisitos gerais para a generalização de resultados, resultando em quatro etapas a serem seguidas. Desta forma, é necessário pelo menos alguma experiência em psicometria ou clinimetria para um amplo uso deste checklist. As aplicações do COSMIN incluem seu uso para garantir a padronização de adaptações transculturais e comparações mais seguras entre estudos de mensuração e avaliação de qualidade metodológica de revisões sistemáticas de propriedades de mensuração. Além disso, ele pode ser usado por estudantes ao treinar sobre propriedades de mensuração e por editores e revisores ao revisar manuscritos sobre este tópico. A divulgação do COSMIN checklist é, portanto, necessária para melhorar a seleção e avaliação dos instrumentos de medição da saúde.

Abstract Adolescence is a vulnerable period for risk-taking tendencies, including binge drinking. The aim of this study was to examined the prevalence of binge drinking and its association with factors related to the consumption of alcoholic beverages by best friend, familial factors, socioeconomic status and religiosity. A Census of 633 students from public and private schools in Diamantina-MG was conducted. Participants completed a self-administered questionnaire, the Alcohol Use Disorders Identification Test-C (AUDIT-C) and, another on the consumption of alcohol by family and friends. Surveys inquiring about socioeconomic conditions were sent to parents/guardians. Descriptive and bivariate analyzes were performed (p < 0.05). The log-binomial model was used to calculate PR and 95% CI. The prevalence of binge drinking was 23.1%. The average age of onset of alcohol consumption was 10,8 years. Binge drinking was more prevalent among adolescents whose best friend [OR = 4.72 (95% CI 2.78-8.03)] and brother [PR = 1.46 (95% CI 1.10-1.92)] drink alcohol. Religiosity [PR = 0.40 (95% CI 0.27-0.62)] appeared as a possible protective factor. Our findings indicate that peer effects are important determinants of drinking and could be utilized as a potential target for interventions to reduce alcohol consumption rates.

Resumo A adolescência é um período vulnerável da tendência em assumir riscos, incluindo consumo excessivo de álcool. Avaliou-se a prevalência de "binge drinking" e sua associação com o consumo de bebidas alcoólicas pelo melhor amigo, fatores familiares, condição socioeconômica e religiosidade. Foi conduzido um censo de 633 alunos de escolas públicas e privadas em Diamantina-MG. Os participantes preencheram o Alcohol Use Disorders Identification Test-C (AUDIT-C) e um questionário sobre o consumo de álcool por familiares e amigos. Questionários com perguntas sobre condições socioeconômicas foram enviados aos pais/responsáveis. Foram realizadas análises descritivas e bivariadas (p < 0,05). O modelo log-binomial foi usado para calcular RP e 95% IC. A prevalência de consumo excessivo de álcool foi de 23,1%. A idade média de início do consumo de álcool foi de 10,8 anos. O "binge drinking" foi mais prevalente entre adolescentes cujo melhor amigo [OR = 4,72 (95% IC 2,78-8,03)] e irmão [RP = 01.46 (IC 95% 1,10-1,92)] consumiam álcool. A religiosidade [RP = 0,40 (IC 95% 0,27-0,62)] apareceu como um possível fator de proteção. Os efeitos de pares são importantes determinantes do consumo de álcool e poderiam ser utilizados como um alvo potencial em intervenções para reduzir as taxas deste.
