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.

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.

Resumo: Quando comparamos temporalmente os marcos no desenvolvimento do futebol feminino e do masculino, podemos notar diferenças com origens para além dos gramados. Na tentativa de compreender melhor o fenômeno do futebol feminino, este artigo descreve e analisa a sua trajetória no Paraná até 1951. Para isso, foram utilizados alguns periódicos da hemeroteca digital brasileira e quatro telegramas encontrados no Arquivo Público do Paraná acerca de um pedido de autorização para realização de uma partida de futebol feminino em Curitiba. Após analisar as fontes, constatou-se que o futebol de mulheres esteve ligado a práticas artísticas a partir de 1934, e que seu ineditismo como esporte no Paraná aconteceu em 1951 no estádio Durival de Britto e Silva com as equipes gaúchas Amazonas e Tiradentes, em um contexto de imposições, contradições e desobediências civis.

Abstract: When we temporally compare the milestones in the development of women's and men's soccer, we can notice differences with origins beyond the fields. In an attempt to better understand the phenomenon of women's soccer, this article describes and analyzes its trajectory in Paraná (Brazil) until 1951. For this, some newspapers of the Brazilian Digital Hemeroteca were used, as well as four telegrams found in the Public Archive of Paraná about a request for authorization to carry out a women's soccer match in Curitiba. After analyzing the sources, it was found that women's soccer was linked to artistic practices from 1934 onwards, and that its beginning as a sport in Paraná occurred in 1951 at the Durival de Britto e Silva stadium with two teams from Rio Grande do Sul — Amazonas and Tiradentes — in a context of impositions, contradictions, and civil disobedience.

Resumen: Al comparar los hitos en el desarrollo del fútbol femenino y masculino a lo largo del tiempo, podemos ver diferencias que se originan más allá del campo de juego. En un intento por comprender mejor el fenómeno del fútbol femenino, este artículo describe y analiza su trayectoria en Paraná (Brasil) hasta 1951. Para ello se utilizaron algunas revistas de la hemeroteca digital brasileña y cuatro telegramas encontrados en el Archivo Público de Paraná sobre una solicitud de autorización para realizar un partido de fútbol femenino en Curitiba. Tras analizar las fuentes, se constató que el fútbol femenino estuvo vinculado a prácticas artísticas desde 1934 y que su inicio como deporte en Paraná se dio en 1951, en el estadio Durival de Britto e Silva con dos equipos de Rio Grande do Sul: Amazonas y Tiradentes, en un contexto de imposiciones, contradicciones y desobediencias civiles.

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.

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

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

Resumo Sistematiza-se estudo sobre a noção de sujeito, suas relações e implicações no trabalho pedagógico dos professores. A produção e a análise dos dados aconteceram por meio da Análise dos Movimentos de Sentidos, fundamento teórico e metodológico que visa ao estudo dos sentidos nos discursos, nas obras e nas produções que integraram o corpus do estudo bibliográfico. O trabalho pedagógico é tratado como um processo em que os professores se reconhecem como integrantes de uma classe trabalhadora e, em tal contexto, produzem, a despeito das contradições sociais, com vistas à superação, conscientes de sua historicidade.

Abstract In this work, we systematize the study of the notion of the subject, its relations, and implications in teachers' pedagogical work. We produced and analyzed data using the Analysis of the Movements of Senses. This theoretical and methodological foundation aims to study the senses in the discourses, works, and productions that constitute the corpus of the bibliographic study. Pedagogical work is seen as a process in which teachers recognize themselves as working-class members. They produce in this context, despite social contradictions, aiming to overcome and be aware of their historicity.

El trabajo pedagógico es tratado como un proceso en el que los docentes se reconocen como miembros de una clase trabajadora y, en este contexto, producen, a pesar de las contradicciones sociales, con miras a la superación, conscientes de su historicidad.

Abstract: The present study aimed to estimate the impact of the COVID-19 pandemic on dental care procedures in the Public Health System in Brazil. A retrospective, ecological study was carried out, comprising 5,564 Brazilian municipalities. The number of dental procedures (per 100,000 inhabitants) performed in the Brazilian Public Health System (SUS) was the outcome. The impact of the pandemic was estimated by comparing the rate of procedures for each month of 2020 with the rates observed in the equivalent months in 2019, considering the period from March to August. Regulatory legislation regarding restrictions on dental care, issued by the state governments of 27 Brazilian federative units, was used for mediation analysis. A 55% reduction was observed in March for all procedures (IRR = 0.45, 95%CI 0.39–0.51), while in the other months, the rate of reduction remained ≥ 88%. The biggest decrease was observed in collective preventive procedures (reduction ≥99%) between April and August. Procedures that were less likely to generate aerosols (tooth extraction and prosthetic) and emergencies showed the smallest reduction. The reduction was not mediated by the restrictions imposed by state governments (p>0.05). The impact of the COVID-19 pandemic was noteworthy in terms of the decrease in the number of dental procedures carried out in the Brazilian Public Dental Service. The lack of access, the delay of elective procedures and the lack of preventive collective procedures could result in an overburdened system, post-Pandemic.

Resumo: O estudo teve como objetivo testar a acurácia e a confiabilidade de um protocolo parcial (PP) para exame oral, envolvendo os primeiros molares permanentes. O estudo transversal foi realizado em duas etapas. Primeiro, foi feito um estudo transversal em uma amostra representativa de 1.211 crianças, usando o índice CPOD com um protocolo de boca completa (BC). O PP foi simulado a partir de dados de BC, usando apenas os dados dos primeiros molares permanentes. A segunda etapa foi realizada em 202 crianças examinadas por um examinador de padrão de ouro (BC) e três odontólogos usando o PP para avaliar a confiabilidade do mesmo. A acurácia do PP foi avaliada pela sensibilidade, especificidade e valores preditivos positivos e negativos. A confiabilidade inter- examinador, comparada com o examinador de padrão de ouro, foi avaliada através do índice kappa ponderado. A prevalência de cárie dentária, medida pelo índice CPOD, foi 32,4%, comparado com 30,2% para o PP. O PP apresentou sensibilidade alta (93,1%; IC95%: 91,5-94,5), com magnitude semelhante nas medidas de associação dos fatores investigados. Quando comparados com o exame de BC (padrão de ouro), todos os examinadores obtiveram níveis altos de sensibilidade e especificidade (em torno de 90%). Os valores preditivos negativos foram mais altos do que os valores preditivos positivos para os examinadores. O estudo mostrou que o protocolo parcial envolvendo os primeiros molares permanentes é acurado e confiável enquanto ferramenta de triagem para avaliar a prevalência de cárie dentária e fatores associados em escolares.

Abstract: The aim of this study was to test accuracy and reliability of a partial protocol (PP) of oral examination involving the permanent first molars. This cross-sectional study was carried out in two stages. First, a cross-sectional study was performed in a representative sample of 1,211 children using DMFT-index in a full-mouth protocol (FM). A PP was simulated from FM data using only data from the permanent first molars. A second part was performed with 202 children examined by a gold standard examiner (FM) and three dentists using the PP to assess its reliability. Accuracy of PP was assessed by sensitivity/specificity/predictive positive and negative values. Inter-examiner reliability in comparison with gold standard examiner was assessed using weighted kappa. The prevalence of dental caries observed using DMFT index was 32.4% and was 30.2% for PP . The PP presented high sensitivity (93.1%; 95%CI: 91.5-94.5), showing similar magnitude of association’s measures for all associated factors investigated. When compared with the gold standard FM examination, all examiners obtained high parameters of sensitivity and specificity (around 90%). Predictive negative values were higher than predictive positive values for the examiners. This study showed that this partial protocol involving the permanent first molars is accurate and reliable as a screening tool to assess dental caries prevalence and associated factors in schoolchildren.

Resumen: El objetivo de este estudio fue probar la precisión y fiabilidad de un protocolo parcial (PP) de exámenes orales, incluyendo los primeros molares permanentes. Este estudio transversal se llevó a cabo en dos etapas. En primer lugar, se desarrolló un estudio transversal con una muestra representativa de 1.211 niños, usando el DMFT-index en un protocolo para toda la boca (FM por sus siglas en inglés). El PP se simuló con datos del FM, usando solo información de los primeros molares permanentes. La segunda parte se realizó con 202 niños examinados por un examinador ideal (FM) y tres dentistas, usando el PP para evaluar su fiabilidad. La precisión del PP se evaluaron por sensibilidad/especificidad/valores predictivos positivos y negativos. La fiabilidad interexaminadores, en comparación con el examinador ideal, fue evaluada usando un índice kappa ponderado. La prevalencia de caries dental observada, usando el índice DMFT fue de un 32,4% y un 30,2% respecto al PP. El PP presentó una alta sensibilidad (93,1%; IC95%: 91,5-94,5), mostrando una magnitud similar de medidas de asociación para todos los factores asociados investigados. Cuando se comparó con el estándar ideal de examen para la FM, todos los examinadores obtuvieron parámetros altos de sensibilidad y especificidad (sobre un 90%). Los valores predictivos negativos eran más altos que los valores predictivos positivos para los examinadores. Este estudio mostró que este protocolo parcial, incluyendo los primeros molares permanentes, es preciso y fiable como herramienta de detección para evaluar la prevalencia de caries dental y sus factores asociados en niños con edad escolar.

Abstract This cross-sectional study aimed to determine the association between dental caries and weight status, and between dental caries and physical activity in Brazilian schoolchildren aged 8 to 12 years. A multi-stage sample of children enrolled in 20 private and public schools in 2010 in Pelotas, Southern Brazil, were invited to participate in the study. Socioeconomic data were collected from parents, and data regarding children characteristics were collected from children using a questionnaire and anthropometric measures. The Body Mass Index was obtained, and children were classified as overweight/obese considering age and sex. Dental examinations were performed to assess the presence of gingival inflammation, dental caries prevalence (DMFT≥1) and dental caries experience (mean DMFT). Multivariate Poisson Regression was used to assess factors associated with dental caries prevalence and experience. A total of 1,210 children were included in the study. Dental caries prevalence was 32.4% (95% CI 29.7-35.2), while the mean DMFT was 0.64 (± SD 1.00). Children who practiced less than 300 minutes per week of physical activity and overweigh/obese children had lower prevalence of dental caries, while children with obesity or overweight presented lower dental caries experience. Obesity/overweight and physical activity level presented an inverse relationship with dental caries. Longitudinal studies investigating the complexity of this relationship are required.

O objetivo deste estudo foi avaliar o efeito da aplicação de clorexidina (CRX) em dentina condicionada na retenção de restaurações confeccionadas em lesões cervicais não-cariosas (LCNC) após 6 meses. Ensaio clínico randomizado triplo cego do tipo boca dividida foi conduzido. Pacientes (n=42) com no mínimo duas LCNC foram incluídos. LCNC foram randomizadas em dois grupos: controle (solução placebo) ou grupo teste (aplicação de CRX 2% por 60 s após o condicionamento e antes da aplicação do adesivo). Restaurações Classe V (n=169) foram realizadas com adesivo de condicionamento ácido total e resina composta, por 10 operadores treinados. Um examinador calibrado avaliou as restaurações após 1 semana (base) e 6 meses usando os critérios da FDI. O desfecho primário foi retenção das restaurações. A análise dos fatores associados à falha das restaurações foi conduzida com Teste Exato de Fisher (α=0,05). Após 6 meses de acompanhamento, 3,4% (IC 95% 1,3-7,3) das restaurações falharam. Não houve diferença estatística entre os grupos CRX e controle (p=0,920). Com relação às variáveis das cavidades, cavidades mais profundas (p=0,024), largas (p=0,004) e em formato de cunha (p=0,033) falharam mais. Ambos os tratamentos (CRX e controle) proporcionaram performance clínica aceitável das restaurações. O uso de CRX como coadjuvante na adesão à dentina não influenciou a retenção das restaurações Classe V após 6 meses de acompanhamento.

This study aimed to evaluate the effect of chlorhexidine (CHX) application on etched dentin on the 6-month retention of restorations placed on non-carious cervical lesions (NCCLs). A randomized controlled split-mouth and triple blind trial was carried out. Patients (n=42) with at least two non-carious cervical lesions were included. NCCLs were randomly assigned to two groups: control (placebo solution) or test group (2% CHX solution for 60 s after acid etching and before the adhesive application). Class V restorations (n=169) were performed with an etch-and-rinse adhesive system and composite resin by 10 trained operators. A calibrated examiner evaluated the restorations at 1 week (baseline) and at 6 months using the FDI criteria. The primary outcome was retention of the restorations. The analysis of factors associated to failure of restorations was carried out by Fisher's exact test (α=0.05). After 6 months of follow-up, 3.4% (CI 95% 1.3-7.3) of the restorations failed. There was no statistically significant difference between control and CHX (p=0.920). Regarding the cavity variables, deeper (p=0.04), wider (p=0.004) and wedge-shaped (p=0.033) cavities failed more. Both treatments provided acceptable clinical performance of the restorations. The use of CHX as a adjuvant in dentin adhesion did not influence the retention of Class V restorations after 6 months of follow-up.

Instrumentos de medida da catastrofização da dor para indivíduos de meia-idade e idosos são necessários para compreensão do impacto na dor lombar nessa população. Os objetivos foram adaptar transculturalmente a Escala de Catastrofização da Dor, avaliar a validade de construto pela análise Rasch, verificar a confiabilidade e a validade convergente da catastrofização da dor com fatores psicossociais. Participaram 131 indivíduos comunitários com 55 anos e mais com dor lombar aguda. A confiabilidade intra-examinadores foi de Kp = 0,80 e inter-examinadores Kp = 0,75. A análise Rasch, detectou adequados coeficientes de confiabilidade (0,95 para itens e 0,90 para indivíduos). O índice de separação dos idosos foi de 2,95 e dos itens 4,59. Dos 13 itens, um não se enquadrou no modelo, o que se justificou na amostra avaliada. A catastrofização da dor se correlacionou com a maioria dos fatores psicossociais. O instrumento mostrou-se clinicamente útil. Estudos subsequentes devem proceder às mesmas análises em diferentes populações.

Measurement instruments of pain catastrophizing for middle-aged and elderly individuals are needed to understand its impact on low back pain. The goals were to cross-culturally adapt the Pain Catastrophizing Scale, assess the construct validity through Rasch analysis, and verify reliability and convergent validity of pain catastrophizing with psychosocial factors. 131 individuals aged 55 years and older with acute low back pain were interviewed . The intra-rater reliability was Kp = 0.80 and interrater Kp = 0.75. The Rasch analysis found adequate reliability coefficients (0.95 for items and 0.90 for individuals ). The separation index for the elderly was 2.95 and 4.59 items. Of the 13 items, one did not fit the model, which was justified in the sample evaluated. The pain catastrophizing correlated with most psychosocial factors. The instrument proved to be clinically useful. Subsequent studies should carry out the same analysis in different populations.

OBJETIVO : Analisar a associação entre ser beneficiário do Programa Bolsa Família e condições de saúde bucal entre escolares. MÉTODOS : Estudo transversal com 1.107 escolares entre oito e 12 anos de idade, provenientes de 20 escolas públicas e particulares da cidade de Pelotas, RS, em 2010. Os beneficiários do Programa Bolsa Família foram verificados por meio de lista fornecida pelas escolas participantes do estudo. Informações demográficas, socioeconômicas, de uso de serviço odontológico e de higiene bucal foram obtidas por meio de questionários respondidos pelos escolares e por seus pais. O exame clínico avaliou a presença de placa dental e experiência de cárie. Os dados foram analisados por meio dos testes do Qui-quadrado e Qui-quadrado de tendência linear e por regressão de Poisson (razão de prevalência; intervalo de confiança de 95%). RESULTADOS : Crianças de família não nuclear, que apresentavam CPOD ≥ 1 e que nunca haviam feito uso de serviço odontológico na vida estiveram associadas ao recebimento do Programa Bolsa Família. O modelo final mostrou que a prevalência de cárie foi duas vezes maior (RP 2,00; IC95% 1,47;2,69) em alunos beneficiários do Programa que também apresentaram maior severidade da doença, quando comparados aos alunos de escolas particulares (RM 1,53; IC95% 1,18;2,00). A prevalência de escolares que nunca haviam ido ao dentista foi mais de seis vezes maior em beneficiários do Programa Bolsa Família (RP 6,18; IC95% 3,07;12,45), em comparação com aqueles das escolas privadas, após ajustes. CONCLUSÕES : Escolares beneficiários do Programa Bolsa Família possuem maior carga de cárie e são os que menos acessam os serviços odontológicos. Esses achados sugerem a necessidade de incorporação da saúde bucal nas condicionalidades do Programa Bolsa Família.

OBJECTIVE : To evaluate the association between being a recipient of the Bolsa Família program and oral health conditions in Brazilian schoolchildren. METHODS : A cross-sectional study was conducted with 1,107 schoolchildren aged between eight and 12 years from 20 public and private schools in Pelotas, RS, Southern Brazil. A list of all children receiving the Bolsa Família program was provided by the participant schools. Demographic, socioeconomic and oral hygiene information were assessed using a questionnaire completed by the schoolchildren and their parents. Dental exams were performed to assess the presence of dental plaque and prevalence of dental caries. Data were analyzed by Chi-square test, Chi-square test for linear trend and multivariate Poisson Regression (prevalence ratio; 95% confidence interval). RESULTS : Schoolchildren from non-nuclear families, with a DMFT ≥ 1 and who had never visited a dentist were associated with receiving the Bolsa Família. Final model showed that caries prevalence was twice as high (PR 2.00; 95%CI 1.47;2.69) in schoolchildren benefiting from the Bolsa Família . It was also showed that schoolchildren benefiting from the program presented greater severity of dental caries compared to school children from private schools (RR 1.53; 95%CI 1.18;2.00). After final adjustments, the prevalence of schoolchildren who have never visited a dentist was six times higher in children who received the government benefit (PR 6.18; 95%CI 3.07;12.45) compared to those from private schools. CONCLUSIONS : Schoolchildren benefiting from the Bolsa Família program experienced more caries lesions and have less frequently accessed dental care services, which suggest the need to include oral health in the program.

OBJETIVO : Analizar la asociación entre ser beneficiario del Programa Beca Familia y condiciones de salud bucal entre escolares. MÉTODOS : Estudio transversal con 1.107 escolares entre ocho y 12 años de edad, provenientes de 20 escuelas públicas y privadas de la ciudad de Pelotas, RS, Brasil, en 2010. El beneficiario del Programa Beca Familia fue verificado por medio de lista suministrada por las escuelas participantes del estudio. Informaciones demográficas, socioeconómicas, de uso de servicio odontológico y de higiene bucal fueron obtenidas por medio de cuestionarios respondidos por los escolares y por sus padres. El examen clínico evaluó la presencia de placa dental y experiencia de caries. Los datos fueron analizados por medio de las pruebas de Chi-cuadrado y Chi-cuadrado de tendencia linear y por regresión de Poisson (cociente de prevalencia; intervalo de confianza de 95%). RESULTADOS : Niños de familia no nuclear, que presentaban COPD ≥1 y que nunca habían hecho uso de servicio odontológico en la vida estuvieron asociados al recibimiento en el Programa Beca Familia. El modelo final mostró que la prevalencia de caries fue dos veces mayor (RP 2,00; IC95% 1,47;2,69) en alumnos beneficiarios del Programa que también presentaron mayor severidad de la enfermedad, al ser comparados con los alumnos de escuelas privadas (RR 1,53; IC95% 1,18;2,00). La prevalencia de escolares que nunca habían ido al dentista fue más de seis veces mayor en beneficiarios del Programa Beca Familia (RP 6,18; IC95% 3,07;12,45), en comparación con aquellos de escuelas privadas, posterior a los ajustes. CONCLUSIONES : Escolares beneficiarios del Programa Beca Familia poseen mayor carga de caries y son los que menos tienen hacen uso de los servicios odontológicos. Estos resultados sugieren la necesidad de incorporar salud bucal en las condiciones del Programa Beca Familia.
