Persistent gender disparity in leading dental publications across four decades: An observational study.

OBJECTIVE: This observational study assessed the differences in the gender of the first and last authors in the most cited dental articles over the last four decades. STUDY DESIGN AND SETTING: Articles were obtained through an electronic search of the most cited articles in dentistry by decade (total n = 400 articles). The 100 most cited studies in each decade (1980 - 1989, 1990 - 1999, 2000 - 2009, and 2010 - 2019), with any study design, with results in dentistry were eligible. The gender of the first and last authors was determined using the Genderize database. Comparative evaluation of gender distribution in general and across the four decades was performed with the Chi-Square test, and the contribution of variables on the citation rate of articles was performed using Linear Regression. RESULTS: There were statistical differences between the gender distributions, with a predominance of men in the first (83.8%) and the last (86.8%) positions (p<0.001). Over the decades, there was a tendency for an increase in the proportion of women as the last author (p = 0.002; Chi-Square Trend Test). However, no statistically significant differences were observed between the genders for the first author in the last four decades (p = 0.163; Chi-Square Trend Test), with an increase of women from 6% to 22% across the last four decades. CONCLUSION: The findings indicate that men lead a large percentage of the most cited articles in dentistry and that this trend does not show substantial modifications over the last years. Nonetheless, for the position of last authorship, an increase in women's representativity was observed over the last decades.

Self-perception of need to replace dentures and oral health-related quality of life: cross-sectional study nested in a Cohort in Southern Brazil

Aim: With the significant increase in life expectancy over the last decades, it is important to understand how oral health can impact the oral health-related quality of life of older adults. This study aimed to investigate the association between need to replace dentures and oral health-related quality of life (OHRQoL) among older adults belonging to a Cohort in southern Brazil. Methods: This cross-sectional study was conducted with data from the 2019 Pelotas Elderly Cohort. The OHRQoL was assessed using the GOHAI. Need to replace dentures was self-report using a question dichotomized into yes/no. In the statistical analysis, unadjusted and adjusted models estimate from linear regression models were calculated. The significance level adopted was 5%. Results: A total of 493 older adults were included. On the GOHAI questionnaire, the mean score was 32.74 (SD±0.16). Individuals considering need of prosthesis replacement were 47.89%. Report of need to replace dentures was associated to lowest mean on the GOHAI score (ß -1.14; 95%CI - 1.80; -0.478, and on the physical (ß -0.56; 95%CI - 0.94 -0.17) and psychosocial (ß -0.48; 95%CI - 0.74; -0.22) dimensions. Conclusion: Our findings highlight the importance of also considering subjective measures of oral health in the dental care of older adults, since reporting the need for denture replacement, regardless of the reason, was associated with a worse oral health-related quality of life, including physical and psychosocial aspects

Can oral health have an impact on academic performance and school absenteeism?: a systematic review and meta-analysis

Aim: The study aimed to evaluate the association between oral health and academic performance and/or school absenteeism. Methods: Electronic searches were performed of the PubMed, Web of Science, SCOPUS and LILACS/BVS databases. We included observational studies that evaluated the association between dental caries, tooth loss, dental pain or oral health status with school absenteeism or academic performance. The studies had to contain a representative sample of the population: schoolchildren, children or adolescents. After the removal of duplicates, the electronic searches produced 3,789 articles. Of these, 25 studies were included in the systematic review and 13 in the meta-analysis. Results: Considering all the studies evaluated in the meta-analysis, seven articles satisfied 100% of the Joanna Briggs Institute Critical Appraisal checklist, and six contained between 90% and 75% positive answers. The pooled effects showed that the chances of school absenteeism were 31% higher in subjects with dental caries (OR 1.31; 95%CI 1.12-1.54). Students with fair/poor dental health had a 50% higher chance of suffering poor academic performance (OR 1.50; 95%CI 1.22-1.84) and 34% higher chance of having problems at school (OR 1.34; 95%CI 1.06-1.70). Students with a history of toothache had a 3.7 higher chance of being absent from school (OR 6.65; 95%CI 1.60-8.32) and 71% higher chance of missing class due to toothache (OR 1.71; 95%CI 1.15-2.56). Subjects with a history of toothache had a 2.5 times higher chance of suffering poor academic performance (OR 2.58; 95% CI 2.04-3.27). Conclusion: Therefore, students with oral problems were more likely to take time off school and present inferior academic performance

Human venous blood derivatives as fetal bovine serum substitute for fibroblast culture cells in a fibrin construct

Aim: Venous blood derivatives (VBDs) have been suggested as substitutes for Fetal Bovine Serum (FBS) to improve the clinical transition of cell-based therapies. The literature is not clear about which is the best VBDs substitute. The present study aimed to evaluate the influence of VBDs on cell viability and describe a new method to seed these cells in a 3D Platelet-Rich Fibrin (PRF). Methods: Blood was processed to obtain Platelet-Poor Plasma from PRF (P-PRF), Human Serum (HS), Platelet-Poor Plasma from PRP (P-PRP), activated-PRP (a-PRP), and Platelet lysate (PL). Cells were supplemented with each VBD at 10% and FBS at 10% was the control. Cell viability (fibroblast 3T3/NIH) test was evaluated with MTT assay in two ways: i) cell-seeded and expanded with VBD; ii) cell-seed with FBS and expanded with VBD. To seed the Fibrin construct, cells were suspended in PBS and dropped into the blood sample before performing Choukroun's protocol for PRF. Constructs were cultured for 7 days in VBD supplements and FBS. Histological and Immunohistochemical analysis with vimentin was performed. Cell viability was analyzed by one-way ANOVA. Results: VBD's production time was very heterogeneous. Cells expanded in HS and a-PRP has grown faster. VBD-supplemented culture media provided cell culture highly sensible to trypsin/EDTA 0.25%. Cells seeded and expanded with VBD presented viability comparable to FBS in HS, a-PRP, and P-PRP (p>0.05) and lower in P-PRF and PL groups (p<0.05). The viability of cell seed with FBS and expanded with VBD was similar between P-PRF, a-PRP, PL, and FBS (p>0.05) and lower in HS and P-PRP (p<0.005). PRF-seeded cells showed a positive expression of vimentin and were able to maintain all cells supplemented with VBD. Conclusion: VBD supplements were able to maintain fibroblast cells in 2D and 3D cultures. The new method of the fibrin-cell construct was efficient to insert the cells into the fibrin network

Sociodemographic and undergraduate-related variables as predictors of dental students' empathy: an e-survey in a south brazilian dental school / Variáveis sociodemográficas e relacionadas à graduação como preditoras da empatia de estudantes de odontologia: um e-survey em uma faculdade de odontologia do Sul do Brasil

Aim: To assess the associations between sociodemographic and undergraduate-related characteristics and empathy scores among dental students in a school in Southern Brazil. Materials and methods: Cross-sectional study developed from self-administered online questionnaires to undergraduate dental students at the Federal University of Pelotas. Outcomes were the total score of empathy obtained through the Interpersonal Reactivity Index (IRI) and the scores obtained in four domains: perspective-taking (PT), fantasy (FA), empathic concern (EC), and personal distress (PD). In RStudio version 4.1.3 simple and adjusted linear regression models with robust residual standard errors were performed. Results: Eighty-seven students were included (response rate 24.4%). Considering the total IRI score, there was a mean score of 3.62 (SD=0.64) by item, and dental students had a mean score of 94.07 (SD=16.62). In adjusted analysis, being a woman increased the IRI (0.505;95%CI 0.187;0.823), EC (0.494;95%CI 0.168;0.819), and PT (0.822; 95%CI 0.329;1.315) scores compared to men. Adjusted associations were found between the EC domain and skin color and between the PT domain and family income. FA scores increased with age and family income and, decreased with dissatisfaction with undergraduate studies, only in the bivariate analysis. Discussion: Dental professionals' empathy is essential in daily practice, improving the patient-professional relationship in a patient-centered care approach. Thus, it is relevant to recognize predictors of empathy among dental students to promote strategies to increase empathy in dental practice. Conclusion: Gender, skin color, family income, age, and satisfaction with undergraduate studies were associated with empathy scores among dental students.

Objetivo: Avaliar associações entre as características sociodemográficas e relacionadas à graduação e os escores de empatia entre estudantes de odontologia de uma escola do Sul do Brasil. Materiais e métodos: Estudo transversal desenvolvido com questionários on-line autoadministrados para estudantes de graduação em odontologia da Universidade Federal de Pelotas. Foram considerados desfechos o escore total de empatia medido pelo Índice de Reatividade Interpessoal (IRI) e os escores obtidos em quatro domínios: tomada de perspectiva (TP), fantasia (FA), consideração empática (CE) e angústia pessoal (AP). No RStudio versão 4.1.3 foram realizadas regressões lineares simples e múltiplas com erros residuais robustos. Resultados: Foram incluídos 87 alunos (taxa de resposta=24,4%). Considerando a pontuação total do IRI, houve média de 3,62 (DP=0,64) por item, e de 94,07 (DP=16,62) por estudante. Na análise multivariável, mulheres tiveram maiores pontuações no IRI (0,505; IC95%0,187;0,823), CE (0,494; IC95%0,168;0,819) e AP (0,822; IC95%0,329;1,315) em comparação aos homens. Foram encontradas associações ajustadas entre o domínio CE e cor da pele e entre o domínio PT e renda familiar. Os escores do domínio FA aumentaram com idade e renda familiar e diminuíram com insatisfação com a graduação, somente em análise bivariada. Discussão: A empatia do profissional de odontologia é essencial na prática diária, melhorando a relação paciente-profissional. Assim, é relevante reconhecer os preditores da empatia entre os estudantes de odontologia, visando estratégias para aumentar a empatia na prática odontológica. Conclusão: Gênero, cor da pele, renda familiar, idade e satisfação com a graduação foram associados aos escores de empatia entre estudantes de odontologia.

Notifications of physical, sexual and emotional violence and neglect against children in Brazil, 2011-2019: an ecological time-series study.

OBJECTIVE: To describe the temporal trend of notifications of physical, sexual and emotional violence and neglect against children in Brazil between 2011 and 2019. METHODS: This was an ecological time-series study based on notifications of violence against children aged 0-9 years held on the Brazilian Notifiable Health Conditions Information System. Age-adjusted notification rates were calculated for Brazil as a whole, by national macro-region and by sex. Trends were assessed using Joinpoint Regression. RESULTS: We analyzed 88,820 notifications of physical violence, 87,141 notifications of sexual violence, 52,359 notifications of emotional violence and 166,664 notifications of neglect. A rising trend was identified for notifications of physical, sexual and emotional violence and neglect for Brazil as a whole and for both sexes. Neglect accounted for the highest rate (95.24 notifications per 100,000 children in 2019). The Northeast and Southeast macro-regions had rising trends for all forms of violence. CONCLUSION: Notifications of physical, sexual and emotional violence and neglect showed rising trends in Brazil in the period studied. IMPLICATIONS FOR SERVICES: Increasing trends in notifications of violence against children highlight the continued need for capacity building in health services, crucial for early detection, effective prevention and coordinated intervention, taking regional variations into account. PERSPECTIVES: Notification of violence against children by health services requires greater commitment by health workers. Future studies could combine multiple national databases and surveys to increase the accuracy of rates and trends.

Use of dental services among adults from a birth cohort in the South region of Brazil.

OBJECTIVE: Measure the prevalence of use of dental services in the previous year and associated factors among 31-year-old adults from a birth cohort of 1982. METHODS: This is a cross-sectional study that analyzed a birth cohort of 1982 from the city of Pelotas. In 1997, a systematic sample of 27% of the city's census sectors was defined and all households in these sectors were visited, where 1,076 15-year-old adolescents were interviewed. For the oral health studies, 900 of these individuals were randomly selected and followed up at 24 and 31 years of age. The study used data collected from 523 individuals in 2013 (at 31 years old). The outcome was visit to the dentist (use of dental services) in the previous year. Demographic factors (sex), socioeconomic factors (income, education), and oral health factors (reason and type of service, self-perception of oral health, dental pain and caries experience - DMFT) were used as independent variables. Prevalence ratios were estimated using Poisson regression. RESULTS: The prevalence of use of dental services in the previous year was 55.3% (95%CI: 51.0-59.5%). In the adjusted analysis, the reason and type of service, self-perception of oral health, and DMFT were associated with the outcome. A stronger association was found with use of dental services in individuals who visited for prevention and used the private service, who were satisfied with their oral health, and who had more caries experiences. CONCLUSION: 55.3% of the cohort sample used dental services in the previous year. Individuals who visited the dentist of private service for preventive reasons, who were very satisfied with their oral health, used these services in a higher proportion. In addition, a higher DMFT index also led to higher use of services.

Discriminatory episodes negatively impact the quality of life of Brazilian dental students: A cross-sectional study.

PURPOSE: This study aimed to evaluate whether discriminatory episodes occurring in the university environment were associated with dental students' self-perceived overall quality of life and assess the cumulative effect of perceived discriminatory experiences on the overall quality of life. METHODS: In this cross-sectional study, all students enrolled in three Brazilian dental schools were invited to participate in a survey between August and October 2019. The outcome was students' self-perceived quality of life, measured through the overall quality of life item of the World Health Organization-Quality of Life Abbreviated Version (WHOQOL-BREF). Descriptive, bivariate, and multivariable logistic regression analyses (95% confidence intervals and α of 5%) were conducted using RStudio software. RESULTS: The sample was composed of 732 students (70.2% response rate). The great part was female (66.9%), white or yellow skin color (67.9%), and were children of highly educated mothers. About 68% of the students reported having experienced at least one of the seven discriminatory experiences presented in the questionnaire and 18.1% reported neutral or negative quality of life. In multivariable analyses, it was estimated that students who experienced at least one episode of discrimination were 2.54 times (95% CI: 1.47-4.34) more likely to report worse quality of life than their counterparts who reported no experience of discrimination. There was also a 25% (95% CI: 1.10-1.42) increase in the odds of reporting poorer quality of life for each additional discriminatory experience reported. CONCLUSION: Reporting at least one discriminatory situation in the academic environment was associated with worse quality of life among dental students, and a cumulative effect was also noted.

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

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

Socioeconomic inequalities related to maternal perception of children's oral health at age 4: Results of a birth cohort.

OBJECTIVES: To estimate socioeconomic inequalities in the maternal perception of children's oral health from a birth cohort study in Brazil. METHODS: The data from this study were collected through perinatal interviews and at the 48-month follow-up from the 2015 Pelotas Birth Cohort Study. The main outcome was the maternal perception of children's oral health, dichotomized into positive (good/very good) and negative (fair/bad/very bad). The secondary outcome was untreated dental caries (absence and presence, according to the ICDAS index - International Caries Detection and Assessment System). For the statistical analysis, the absolute inequality index (Slope Index of Inequality - SII) and the relative concentration index (Concentration Index - CIX) were used. Analyses were stratified by maternal educational level, family income and wealth index. RESULTS: The prevalence of outcomes was 19.4% (95% CI 18.2; 20.7) for the negative maternal perception of children's oral health and 15.6% (95% CI 14.4; 16.8) for untreated dental caries. Socioeconomics inequalities were observed in negative maternal perception of children's oral health in both absolute and relative terms. A SII of -16.6 (95% CI -20.8; -12.5) was observed for family income, with higher prevalence in poor families. A higher prevalence of the negative maternal perception of children's oral health was observed in mothers without any educational level or a few years of study (CIX -21.1 [95% CI -24.5; -17.7]). CONCLUSIONS: This study demonstrates socioeconomics disparities in the maternal perception of children's oral health and in the prevalence of untreated caries in children. A higher concentration of negative maternal perception of children's oral health was identified among the most socioeconomically vulnerable individuals. The findings reinforce the presence of socioeconomic inequalities in subjective measures about children's oral health.

Two decades of socioeconomic inequalities in the prevalence of untreated dental caries in early childhood: Results from three birth cohorts in southern Brazil.

OBJECTIVES: To estimate the socioeconomic disparities in untreated dental caries in early childhood according to socioeconomic characteristics in three birth cohorts in Southern Brazil. METHODS: The socioeconomic data to this study were collected at the 48-month follow-up and oral health studies of 1993, 2004 and 2015 Pelotas birth cohort studies. The outcome was untreated dental caries in children aged 6 (1993 cohort), 5 (2004 cohort) and 4 years (2015 cohort), dichotomized into absence/presence. Analyses were stratified by maternal skin colour/race, maternal education and family income. For statistical purposes, the prevalence difference, relative risk and absolute and relative indices of health inequality (Slope Index of Inequality-SII and Concentration Index-CIX) were used. RESULTS: The prevalence of untreated dental caries in primary dentition was 63.4%, 45.5% and 15.6%, in 1993, 2004 and 2015 cohorts, respectively. The prevalence of untreated dental caries was concentrated in the poorest quintile and lower maternal education group in both absolute (SII) and relative (CIX) measures of inequality, being characterized as a pro-poor event. A higher risk of untreated caries was found in the poorest quintile of family income compared with the richest quintile in the 1993 cohort (RR 1.44 [95% CI 1.05; 1.98]). That risk was higher considering the 2004 Cohort (RR 1.78 [95% CI 1.42; 2.23]) and 2015 cohort (RR 4.20 [95% CI 2.97; 5.94]) data. CONCLUSIONS: Over the course of two decades, a higher prevalence of untreated dental caries is concentrated among the most socioeconomically deprived children.

Association Involving Possible Sleep Bruxism, Stress, and Depressive Symptoms in Brazilian University Students: A Cross-sectional Study.

The aim of the present study was to examine the association regarding sleep bruxism (SB), depression, and stress in Brazilian university students. We conducted a cross-sectional study with a large-sample of university students ( n = 2,089) in the city of Pelotas, Rio Grande do Sul, Southern Brazil. A self-administered questionnaire was sent to classrooms to evaluate socioeconomic and demographic characteristics. Possible SB was detected by self-report according to the International Consensus on The Assessment of Bruxism Criteria (2018). The Patient Health Questionnaire-9 and the Perceived Stress Scale were used to assess depression and stress symptoms respectively. Crude and adjusted Poisson regression analyses were performed. The prevalence of possible SB, high level of stress, and depressive symptoms in the sample were of 20.4%, 16.6%, and 16.6% respectively. Stress in female students was significantly associated with an increased prevalence of possible SB, but not in male students. Regarding depression, the prevalence of SB was 28% higher in students with depressive symptoms. Students with stress or depression had a 35% higher prevalence of SB than those without any symptoms. Conclusion The findings have shown that university students with stress and depressive symptoms were more likely to be detected with possible SB.

Use of dental services among adults from a birth cohort in the South region of Brazil / Uso de serviços odontológicos em adultos de uma coorte de nascimentos no sul do Brasil

ABSTRACT OBJECTIVE Measure the prevalence of use of dental services in the previous year and associated factors among 31-year-old adults from a birth cohort of 1982. METHODS This is a cross-sectional study that analyzed a birth cohort of 1982 from the city of Pelotas. In 1997, a systematic sample of 27% of the city's census sectors was defined and all households in these sectors were visited, where 1,076 15-year-old adolescents were interviewed. For the oral health studies, 900 of these individuals were randomly selected and followed up at 24 and 31 years of age. The study used data collected from 523 individuals in 2013 (at 31 years old). The outcome was visit to the dentist (use of dental services) in the previous year. Demographic factors (sex), socioeconomic factors (income, education), and oral health factors (reason and type of service, self-perception of oral health, dental pain and caries experience - DMFT) were used as independent variables. Prevalence ratios were estimated using Poisson regression. RESULTS The prevalence of use of dental services in the previous year was 55.3% (95%CI: 51.0-59.5%). In the adjusted analysis, the reason and type of service, self-perception of oral health, and DMFT were associated with the outcome. A stronger association was found with use of dental services in individuals who visited for prevention and used the private service, who were satisfied with their oral health, and who had more caries experiences. CONCLUSION 55.3% of the cohort sample used dental services in the previous year. Individuals who visited the dentist of private service for preventive reasons, who were very satisfied with their oral health, used these services in a higher proportion. In addition, a higher DMFT index also led to higher use of services.

RESUMO OBJETIVO Mensurar a prevalência de uso de serviços odontológicos no último ano e os fatores associados em adultos de 31 anos pertencentes à coorte de nascimentos de 1982. MÉTODOS Estudo transversal, aninhado na coorte de nascimentos de Pelotas de 1982. Em 1997, uma amostra sistemática de 27% dos setores censitários da cidade foi realizada e todos os domicílios desses setores foram visitados, onde 1.076 adolescentes de 15 anos foram entrevistados. Para os estudos de saúde bucal foram sorteados aleatoriamente 900 desses indivíduos, que foram acompanhados também aos 24 e 31 anos. O estudo utilizou dados coletados de 523 indivíduos em 2013 (aos 31 anos). O desfecho foi a ida ao dentista (uso do serviço) no último ano. Fatores demográficos, (sexo), socioeconômicos (renda, escolaridade) e de saúde bucal (motivo e tipo de serviço da consulta, autopercepção de saúde bucal, dor e experiência de cárie - CPOD) foram utilizados como variáveis independentes. As razões de prevalência foram estimadas usando a regressão de Poisson. RESULTADOS A prevalência de uso de serviços odontológicos no último ano foi de 55,3% (IC95%: 51,0 -59,5%). Na análise ajustada, o motivo e tipo de serviço da consulta, a autopercepção de saúde bucal e o CPOD foram associados ao desfecho. Foi encontrada maior associação com a utilização de serviços odontológicos em indivíduos que visitaram por prevenção e usaram o serviço privado, satisfeitos com a sua saúde bucal e que tinham maior experiência de cárie. CONCLUSÃO 55,3% da amostra da coorte utilizaram os seviços odontológicos no último ano. Os indivíduos que visitaram o dentista por motivo preventivo, em consulta privada, que estavam muito satisfeitos ou satisfeitos com sua saúde bucal utilizaram em maior proporção esses serviços. Além disso, o maior índice de CPOD também levou ao maior uso.

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

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

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

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