Abstract The present study aimed to investigate the contextual inequalities of specialized public dental care (SPDC) in Brazil. The outcome was the trajectory of dental specialized production in municipalities with SPDC (from 2015 to 2017) obtained by group-based trajectory modeling. A Poisson regression model was used to analyze the factors associated with the high trajectory of SPDC production. The inequality indicators for SPDC production were the slope index and the concentration index according to contextual factors. The study included 954 SPDC units distributed across 893 municipalities. Among the municipalities evaluated, 62.9% had a low trajectory of SPDC. Large-sized municipalities had the highest production (IRR = 2.84, 95%CI: 1.94–4.14) and the southern region had the lowest production (IRR = 0.73, 95%CI: 0.58–0.92). Municipalities presenting a very high human development index (HDI) showed the greatest SPDC production (IRR = 3.34, 95%CI: 1.09–10.24), as well as municipalities with the highest tertile of schooling rate (IRR = 1.23, 95%CI: 1.00–1.50). The absolute inequality was 52.1 percentage points for the average monthly wage (p < 0.001), 61.0 percentage points for the HDI (p < 0.001), -22.1 for infant mortality rate (p <0.001), and 14.8 for the schooling rate (p = 0.012). Thus, there are contextual inequalities in the Brazilian SPDC. Higher scores for social indicators were associated with better SPDC performance.

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. andor PubMed Science LILACSBVS LILACS BVS databases loss population schoolchildren adolescents duplicates 3789 3 789 3,78 these 2 1 metaanalysis. metaanalysis meta analysis. analysis meta-analysis metaanalysis, analysis, 100 checklist 90 75 answers 31 OR 1.31 131 95CI 95 1.121.54. 112154 1.12 1.54 . 12 54 1.12-1.54) fairpoor fair 50 1.50 150 1.221.84 122184 1.22 1.84 22 84 1.22-1.84 34 1.34 134 1.061.70. 106170 1.06 1.70 06 70 1.06-1.70) 37 7 3. 6.65 665 6 65 1.608.32 160832 1.60 8.32 60 8 32 1.60-8.32 71 1.71 171 1.152.56. 115256 1.15 2.56 15 56 1.15-2.56) 5 2. 2.58 258 58 2.043.27. 204327 2.04 3.27 04 27 2.04-3.27) Therefore 378 78 3,7 10 9 1.3 121 1.121.54 11215 112 1.1 154 1.5 1.12-1.54 221 1.221.8 12218 122 1.2 184 1.8 1.22-1.8 061 1.061.70 10617 106 1.0 170 1.7 0 1.06-1.70 6.6 66 608 1.608.3 16083 160 1.6 832 8.3 1.60-8.3 17 152 1.152.56 11525 115 256 1.15-2.56 043 2.043.27 20432 204 2.0 327 3.2 2.04-3.27 3, 1. 1.121.5 1121 11 1.12-1.5 1.221. 1221 18 1.22-1. 1.061.7 1061 1.06-1.7 6. 1.608. 1608 16 83 8. 1.60-8. 1.152.5 1152 1.15-2.5 2.043.2 2043 20 2.04-3.2 1.121. 1.12-1. 1.221 1.22-1 1.061. 1.06-1. 1.608 1.60-8 1.152. 1.15-2. 2.043. 2.04-3. 1.121 1.12-1 1.22- 1.061 1.06-1 1.60- 1.152 1.15-2 2.043 2.04-3 1.12- 1.06- 1.15- 2.04-

Abstract The objective of this study was to evaluate Brazilian dental researchers’ perceptions of research integrity and open science practices, as well as their perceptions of the way researchers are evaluated for promotion, hiring, and receiving grants. In a self-administered online survey, the respondents were presented with 3 questions on researcher evaluation in Brazil. Additionally, for 25 academic activities or characteristics, researchers rated their perceived importance for a) career advancement, b) science advancement, c) personal satisfaction, and d) social impact. The questionnaire was sent to a total of 2,179 dental researchers working in graduate programs in dentistry in Brazil. Multilevel regressions were performed to statistically confirm the differences between the predefined subgroups. Three hundred and fifty-five (16%) researchers completed the survey. Most respondents (96.1%) considered the current evaluation system to be flawed and indicated the need for improvement. Non-traditional activities were considered more important than traditional ones for science advancement (p < 0.01), and social impact (p < 0.01), whereas traditional activities were perceived to be more important only for career advancement (p < 0.01). Although Brazilian dental researchers recognize the value of open science and research integrity practices for science advancement and impact on society, they perceive that the current evaluation system emphasizes traditional activities, such as publishing many papers in well-recognized journals as criteria for advancing their careers. promotion hiring grants selfadministered self administered survey Brazil Additionally 2 characteristics b c satisfaction d 2179 179 2,17 subgroups fiftyfive fifty five 16% 16 (16% 96.1% 961 96 1 (96.1% improvement Nontraditional Non p 0.01, 001 0.01 , 0 01 0.01) 0.01. . society wellrecognized recognized careers 217 17 2,1 (16 96.1 9 (96.1 00 0.0 21 2, (1 96.

Resumo Este estudo analisou a prevalência de palestras envolvendo estética na programação científica de congressos de Odontologia brasileiros, e a distribuição do gênero dos palestrantes. Todas as palestras apresentadas em três congressos de Odontologia (CIOBA, CIOGO, and CIOSP) entre 2016 e 2020 foram avaliadas. Três avaliadores utilizaram os títulos das palestras para dividi-las entre as especialidades reconhecidas pelo Conselho Federal de Odontologia (CFO) do Brasil. As palestras foram também classificadas como envolvendo ou não estética, e o gênero do palestrante foi registrado. Análises estatísticas descritivas foram realizadas, e testes de Qui-quadrado avaliaram possíveis interações entre fatores. A palavra mais citada nos títulos das palestras foi “estética” (13,6%), seguido por “odontologia” (9,9%) e “tratamento” (8,1%). Doenças orais foram raramente mencionadas nos títulos (até 1,3%). O maior número de palestras foi observado para a especialidade de Dentística (22,3%), seguido por Prótese Dental (18,3%). Aproximadamente um terço das palestras envolviam algum aspecto estético, com porcentagens entre 71,9 a 78,6% para as duas especialidades com mais palestras. Em relação ao gênero do palestrante, a inequidade foi maior para palestras envolvendo estética (81,6% de homens) que para tópicos não relacionadas à estética (66,7%). Mais palestrantes do sexo masculino que feminino foram observados para todas as especialidades. A maior discrepância entre os gêneros foi observada para Odontopediatria, uma especialidade com 62,4% dos palestrantes do sexo masculino, embora apenas 10,6% dos especialistas registrados no CFO eram homens. Como conclusão, os congressos de Odontologia Brasileiros parecem preferir palestras abordando tópicos de estética e palestrantes do sexo masculino. brasileiros CIOBA, CIOBA (CIOBA CIOGO CIOSP 201 202 avaliadas dividilas dividi las (CFO Brasil registrado realizadas Quiquadrado Qui quadrado fatores “estética 13,6%, 136 13,6% , 13 6 (13,6%) odontologia “odontologia 9,9% 99 9 (9,9% tratamento “tratamento 8,1%. 81 8,1% . 8 1 (8,1%) até 1,3%. 1,3% 3 1,3%) 22,3%, 223 22,3% 22 (22,3%) 18,3%. 183 18,3% 18 (18,3%) estético 719 71 71, 786 78 78,6 81,6% 816 (81,6 homens 66,7%. 667 66,7% 66 7 (66,7%) Odontopediatria 624 62 4 62,4 106 10 10,6 conclusão 20 13,6 (13,6% 9,9 (9,9 8,1 (8,1% 1,3 22,3 2 (22,3% 18,3 (18,3% 78, 81,6 (81, 66,7 (66,7% 62, 10, 13, (13,6 9, (9, 8, (8,1 1, 22, (22,3 18, (18,3 81, (81 66, (66,7 (13, (9 (8, (22, (18, (8 (66, (13 ( (22 (18 (66 (1 (2 (6

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

Abstract Although periodontal disease is common during pregnancy, little is known about socioeconomic, behavioral, or biological determinants related to clinically assessed periodontal condition during this period. We assessed the prevalence of periodontal disease and associated factors in pregnant women. This population-based survey used data used from the 2015 Pelotas Birth Cohort Study, Brazil. Pregnant women expected to give birth between December 2014 and May 2016 were interviewed and clinically examined by trained dentist, with periodontal measures collected in all teeth, six sites per tooth. Outcomes were periodontitis (using the 2012 Centers for Disease Control and Prevention and the American Academy of Periodontology criteria) and gingivitis (by the 2018 European Federation of Periodontology/ American Academy of Periodontology classification). Multivariate hierarchical Poisson regression was used to assess the associations between socioeconomic, systemic, and clinical oral factors and periodontal disease. A total of 2,474 pregnant women participated in the study. Prevalence of periodontitis and gingivitis was 14.63% and 21.67%, respectively. Lower educational level and calculus were associated with higher prevalence periodontitis and gingivitis (P<0.05). Smoking was also associated with periodontitis (P=0.05), and lower frequency of toothbrushing (P=0.005) with gingivitis. Periodontal disease, especially gingivitis, was prevalent in pregnant women and their determinants were socioeconomic, environmental, and clinical oral health factors. pregnancy socioeconomic behavioral period populationbased population based 201 Study Brazil dentist teeth tooth using criteria classification. classification . classification) systemic 2474 2 474 2,47 study 1463 14 63 14.63 2167 21 67 21.67% respectively P<0.05.

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 cross-sectional 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.

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

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

O estudo teve como objetivo estimar as desigualdades sociais e raciais na autoavaliação da saúde bucal em adultos de um estudo de coorte de nascimentos no Brasil. O estudo atual faz parte do estudo de coorte de nascimentos de 1982 de Pelotas, Rio Grande do Sul, Brasil. Os dados foram coletados sobre as condições de saúde bucal aos 31 anos (Estudo de Saúde Bucal). A variável de desfecho era a autoavaliação da saúde bucal, dicotomizada em positiva (boa/muito boa) vs. negativa (regular/ruim/muito ruim). As análises foram estratificadas por sexo, grupo étnico-racial, escolaridade e renda. Para a análise estatística, foram utilizados o índice de desigualdade absoluta (SII) e o índice de concentração (CIX). A prevalência de autoavaliação da saúde bucal negativa foi 36,1%. Foram observadas desigualdades na autoavaliação da saúde bucal, em termos tanto absolutos quanto relativos. Foram observados SII de -30,0 (IC95%: -43,6; -16,4) para renda e -27,7 (IC95%: -41,9; -13,4) para escolaridade. Renda individual e escolaridade tiveram CIX negativos (CIXrenda -14,6 [IC95%: -21,2; -8,0] e CIXescolaridade -14,1 [IC95%: -20,7; -7,5]). Além disso, a prevalência de autoavaliação da saúde bucal negativa em indivíduos pretos, pardos e indígenas nas faixas de renda e escolaridade mais altas era comparável à prevalência desse desfecho entre indivíduos brancos pertencentes ao menor nível de renda e escolaridade. Os resultados desse estudo revelam disparidades raciais na saúde bucal, independente de renda e escolaridade. Além disso, foi identificada maior concentração de autoavaliação da saúde bucal negativa entre indivíduos com maior vulnerabilidade socioeconômica. Os achados reforçam a presença de desigualdades raciais e socioeconômica na saúde bucal no Brasil.

This study aimed to estimate social and racial inequalities in self-rated oral health in adults from the Brazilian birth cohort study. This study belongs to 1982 Pelotas (Brazil) birth cohort study. Data from this study was collected for oral health conditions 31 years old (Oral Health Study). The outcome was self-rated oral health, dichotomized into positive (good/very good) and negative (regular/bad/very bad). Analyses were stratified by gender, racial/skin color groups, schooling level and income. For statistical analysis, the slope index of inequality (SII) and the concentration index (CIX) were used. The prevalence of negative self-rated oral health was 36.1%. Social inequalities were observed in self-rated oral health in both absolute and relative terms. A SII of -30.0 (95%CI: -43.6; -16.4) was observed for income, and -27.7 (95%CI: -41.9; -13.4) for schooling level. Both the individuals’ income and the schooling level had negative CIX (CIXincome -14.6 [95%CI: -21.2; -8.0] and CIXschooling level -14.1 [95%CI: -20.7; -7.5]). Furthermore, the prevalence of negative self-rated oral health in black/brown/indigenous individuals from the highest income/schooling level was comparable to prevalence of the outcome in the white individuals belonging to the lowest income/schooling levels. This study results demonstrate racial disparities in oral health regardless of income and schooling levels. Furthermore, a higher concentration of negative self-rated oral health was identified among the most socioeconomically vulnerable individuals. Our findings reinforce the presence of racial and socioeconomic inequalities in oral health.

El objetivo fue estimar las inequidades sociales y raciales en la salud oral autoinformada de adultos, mediante el estudio de una cohorte de nacimientos en Brasil. Este trabajo pertenece al estudio de la cohorte de nacimientos de 1982 en Pelotas (Rio Grande do Sul, Brasil). Los datos que se recogieron en este estudio estaban relacionados con las condiciones de salud oral durante 31 años (Estudio de Salud Oral). El resultado fue la salud oral autoinformada, dicotomizada en positiva (buena/muy buena) y negativa (regular/mala/muy mala). Los análisis se estratificaron por sexo, grupos raciales/étnicos, nivel educacional e ingresos. Para el análisis estadístico se usaron el índice de inequidad absoluto (SII) y el índice de concentración (CIX). La prevalencia de salud oral autoinformada negativa fue 36,1%. Se observaron inequidades sociales en salud oral autoinformada tanto en términos absolutos como relativos. Se observó un SII de -30,0 (IC95%: -43,6; -16,4) en ingresos, y de -27,7 (IC95%: -41,9; -13,4) en la escolaridad alcanzada. Tanto los ingresos individuales, como la escolaridad alcanzada, tuvieron un CIX negativo (ingreso CIX -14,6 [IC95%: -21,2; -8,0] y un nivel CIXeducacional -14,1 [IC95%: -20,7; -7,5]). Asimismo, la prevalencia de una salud oral autoinformada negativa en individuos negros/mestizos/indígenas del nivel más alto de ingresos/educación fue comparable a la prevalencia del resultado en los individuos blancos que pertenecen a los niveles más bajos de ingresos/educacionales. Los resultados de este estudio demuestran disparidades raciales en la salud oral, independientemente de los ingresos y educación. Además, se identificó una concentración más alta de salud oral autoinformada negativa entre los individuos más vulnerables socioeconómicamente. Estos hallazgos refuerzan la presencia de inequidades raciales y socioeconómicas en la salud oral.

O estudo teve como objetivo estimar as desigualdades sociais e raciais na autoavaliação da saúde bucal em adultos de um estudo de coorte de nascimentos no Brasil. O estudo atual faz parte do estudo de coorte de nascimentos de 1982 de Pelotas, Rio Grande do Sul, Brasil. Os dados foram coletados sobre as condições de saúde bucal aos 31 anos (Estudo de Saúde Bucal). A variável de desfecho era a autoavaliação da saúde bucal, dicotomizada em positiva (boa/muito boa) vs. negativa (regular/ruim/muito ruim). As análises foram estratificadas por sexo, grupo étnico-racial, escolaridade e renda. Para a análise estatística, foram utilizados o índice de desigualdade absoluta (SII) e o índice de concentração (CIX). A prevalência de autoavaliação da saúde bucal negativa foi 36,1%. Foram observadas desigualdades na autoavaliação da saúde bucal, em termos tanto absolutos quanto relativos. Foram observados SII de -30,0 (IC95%: -43,6; -16,4) para renda e -27,7 (IC95%: -41,9; -13,4) para escolaridade. Renda individual e escolaridade tiveram CIX negativos (CIXrenda -14,6 [IC95%: -21,2; -8,0] e CIXescolaridade -14,1 [IC95%: -20,7; -7,5]). Além disso, a prevalência de autoavaliação da saúde bucal negativa em indivíduos pretos, pardos e indígenas nas faixas de renda e escolaridade mais altas era comparável à prevalência desse desfecho entre indivíduos brancos pertencentes ao menor nível de renda e escolaridade. Os resultados desse estudo revelam disparidades raciais na saúde bucal, independente de renda e escolaridade. Além disso, foi identificada maior concentração de autoavaliação da saúde bucal negativa entre indivíduos com maior vulnerabilidade socioeconômica. Os achados reforçam a presença de desigualdades raciais e socioeconômica na saúde bucal no Brasil.

This study aimed to estimate social and racial inequalities in self-rated oral health in adults from the Brazilian birth cohort study. This study belongs to 1982 Pelotas (Brazil) birth cohort study. Data from this study was collected for oral health conditions 31 years old (Oral Health Study). The outcome was self-rated oral health, dichotomized into positive (good/very good) and negative (regular/bad/very bad). Analyses were stratified by gender, racial/skin color groups, schooling level and income. For statistical analysis, the slope index of inequality (SII) and the concentration index (CIX) were used. The prevalence of negative self-rated oral health was 36.1%. Social inequalities were observed in self-rated oral health in both absolute and relative terms. A SII of -30.0 (95%CI: -43.6; -16.4) was observed for income, and -27.7 (95%CI: -41.9; -13.4) for schooling level. Both the individuals’ income and the schooling level had negative CIX (CIXincome -14.6 [95%CI: -21.2; -8.0] and CIXschooling level -14.1 [95%CI: -20.7; -7.5]). Furthermore, the prevalence of negative self-rated oral health in black/brown/indigenous individuals from the highest income/schooling level was comparable to prevalence of the outcome in the white individuals belonging to the lowest income/schooling levels. This study results demonstrate racial disparities in oral health regardless of income and schooling levels. Furthermore, a higher concentration of negative self-rated oral health was identified among the most socioeconomically vulnerable individuals. Our findings reinforce the presence of racial and socioeconomic inequalities in oral health.

El objetivo fue estimar las inequidades sociales y raciales en la salud oral autoinformada de adultos, mediante el estudio de una cohorte de nacimientos en Brasil. Este trabajo pertenece al estudio de la cohorte de nacimientos de 1982 en Pelotas (Rio Grande do Sul, Brasil). Los datos que se recogieron en este estudio estaban relacionados con las condiciones de salud oral durante 31 años (Estudio de Salud Oral). El resultado fue la salud oral autoinformada, dicotomizada en positiva (buena/muy buena) y negativa (regular/mala/muy mala). Los análisis se estratificaron por sexo, grupos raciales/étnicos, nivel educacional e ingresos. Para el análisis estadístico se usaron el índice de inequidad absoluto (SII) y el índice de concentración (CIX). La prevalencia de salud oral autoinformada negativa fue 36,1%. Se observaron inequidades sociales en salud oral autoinformada tanto en términos absolutos como relativos. Se observó un SII de -30,0 (IC95%: -43,6; -16,4) en ingresos, y de -27,7 (IC95%: -41,9; -13,4) en la escolaridad alcanzada. Tanto los ingresos individuales, como la escolaridad alcanzada, tuvieron un CIX negativo (ingreso CIX -14,6 [IC95%: -21,2; -8,0] y un nivel CIXeducacional -14,1 [IC95%: -20,7; -7,5]). Asimismo, la prevalencia de una salud oral autoinformada negativa en individuos negros/mestizos/indígenas del nivel más alto de ingresos/educación fue comparable a la prevalencia del resultado en los individuos blancos que pertenecen a los niveles más bajos de ingresos/educacionales. Los resultados de este estudio demuestran disparidades raciales en la salud oral, independientemente de los ingresos y educación. Además, se identificó una concentración más alta de salud oral autoinformada negativa entre los individuos más vulnerables socioeconómicamente. Estos hallazgos refuerzan la presencia de inequidades raciales y socioeconómicas en la salud oral.

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

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

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

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

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

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

Cuando consideramos a individuos con pérdidas de dientes anteriores, los resultados mostraron una buena concordancia (kappa: 0,82) y precisión entre necesidad normativa y subjetiva (SE: 93,3, IC95%: 68,1-99,8; SP: 88,9, IC95%: 51,8-99,7; PPV: 93,3, IC95%: 68,1-99,8); NPV: 88,9, IC95%: 51,8-99,7). La dirección y magnitud de las asociaciones con necesidad normativa y subjetiva fueron similares. Por lo tanto, la necesidad normativa de prótesis dentales difiere de la necesidad subjetiva en adultos, excepto cuando están presentes las pérdidas de dientes anteriores.
