Abstract The aim of this study was to assess the factors associated with oral health-related quality of life in adolescents (OHRQoL). Individual data on adolescents were collected from a secondary database. OHRQoL was measured using the oral impact on daily performance (OIDP) scale. Individual- and city-level variables were selected to represent the structural and intermediate determinants of health. The individual covariates analyzed were sex, age, skin color, maternal education, household income, number of people per room in the housing unit, dental attendance, self-perception of dental needs, untreated dental caries, and gingival bleeding. The contextual variables included the allocation factor, the Human Development Index (HDI), Gini coefficient, illiteracy, unemployment, income, average number of emergency dental visits per inhabitant, access to a sanitary sewer system, garbage collection, primary health care coverage, oral health team coverage, and number of tooth extractions between selected dental procedures and supervised toothbrushing. Unadjusted and adjusted multilevel Poisson regression analyses were used to evaluate the relationship between contextual and individual variables with overall OIDP scores (STATA version 16.0) - rate ratio (RR) and 95%CI. The mean OIDP score was 0.72 and the prevalence was 31.8%. There was an association between supervised toothbrushing average and the outcome (RR 0.95; 95%CI 0.91–0.99). Moreover, adolescents who lived in municipalities with the highest average number of emergency dental visits per inhabitant showed a higher OIDP. Sex, maternal education, untreated dental caries, and gingival bleeding were associated with OIDP. In addition, intersectoral public policies focusing on the reduction of social inequalities should be on the agenda of policymakers and stakeholders. healthrelated related OHRQoL. .

Abstract The present study aimed to investigate the prevalence of dissatisfaction with dental appearance among 24-year-old Brazilian adults and the associated factors in life course. A subsample (n = 720) of the 1982 Pelotas Birth Cohort in southern Brazil was investigated at the ages of 15 and 24 years using clinical (caries and periodontal) examinations and interviews. The outcome was dissatisfaction with dental appearance at the age of 24 years. Covariate variables included socioeconomic factors, oral health, and dissatisfaction with general appearance collected during different periods of life. Poisson regression models with robust variance were applied. The prevalence of dissatisfaction with dental appearance was 43.5% (95%CI: 39.8–47.1). Individuals with downward income mobility (PR = 1.22, 95%CI: 1.07–1.79) and those always poor (PR = 1.21, 95%CI: 1.00–1.57) presented a higher prevalence of dissatisfaction with their dental appearance even after oral health variables and dissatisfaction with general appearance were controlled for. Moderate/severe malocclusion at 15 years (PR = 1.34, 95%CI: 1.13–1.59), highest experience of untreated dental caries at 24 years (PR = 1.82, 95%CI: 1.46–2.27), and dental pain experience at 24 years (PR = 1.29, 95%CI: 1.22–1.75) were associated with the outcome. Also, the prevalence of dissatisfaction with dental appearance was 20% higher (PR = 1.20, 95%CI: 1.01–1.43) among those dissatisfied with their general appearance. Our findings demonstrated a high prevalence of dissatisfaction with dental appearance among young adults. Lifetime economic disadvantage and dental problems (malocclusion at 15 years, untreated dental caries at 24 years, and dental pain at 24 years) were associated with dissatisfaction with dental appearance among young adults. 24yearold yearold year old course n 720 198 1 2 periodontal interviews applied 435 43 5 43.5 95%CI 95CI CI 95 (95%CI 39.8–47.1. 398471 39.8–47.1 . 39 8 47 39.8–47.1) PR 122 22 1.22 1.07–1.79 107179 07 79 121 21 1.21 1.00–1.57 100157 00 57 for Moderatesevere Moderate severe 134 34 1.34 1.13–1.59, 113159 1.13–1.59 , 13 59 1.13–1.59) 182 82 1.82 1.46–2.27, 146227 1.46–2.27 46 27 1.46–2.27) 129 29 1.29 1.22–1.75 122175 75 Also 20 120 1.20 1.01–1.43 101143 01 72 19 4 43. 9 39847 39.8–47. 3 12 1.2 1.07–1.7 10717 0 7 1.00–1.5 10015 1.3 11315 1.13–1.5 18 1.8 14622 1.46–2.2 1.22–1.7 12217 1.01–1.4 10114 3984 39.8–47 1. 1.07–1. 1071 1.00–1. 1001 1131 1.13–1. 1462 1.46–2. 1.22–1. 1221 1.01–1. 1011 398 39.8–4 1.07–1 107 1.00–1 100 113 1.13–1 146 1.46–2 1.22–1 1.01–1 101 39.8– 1.07– 10 1.00– 11 1.13– 14 1.46– 1.22– 1.01– 39.8 1.07 1.00 1.13 1.46 1.01 39. 1.0 1.1 1.4

The study assessed the Global Quality Score (GQS) and informational engagement of users with YouTube videos on the Brazilian public health system (SUS). The YouTube video search tool was used with the Portuguese keywords ‘unified health system’ and ‘SUS’. The first 100 videos returned in the search were studied, using the GQS to measure their educational value, usefulness, and information quality. Users’ engagement with the videos was calculated based on their number of likes/reactions and comments. Other data collected were authorship, year of publication, topic approached, target audience, video length, and use of references. Two trained and calibrated researchers collected the data. Multiple analysis was performed with Logistic Regression, using a 95% confidence interval and significance of p<0.05. There were no poor or generally poor GQS scores (scores 1 and 2) and most videos (58%) achieved moderate or good scores (scores 3 and 4). Videos published after the onset of COVID-19 had a 70% lower chance of engagement than those published in pre-pandemic years (OR: 0.30; 95%CI: 0.12–0.74). Videos that targeted healthcare professionals were 72% less likely to achieve higher GQS scores, than those with an unidentified target audience (OR: 0.28; 95%CI: 0.10–0.75). The informational engagement of the videos showed fewer comments than likes/reactions. Most YouTube videos about the SUS had moderate or good global quality, which was associated with their period of publication and choice of target audience. (GQS SUS. .

Abstract: This cross-sectional study evaluated factors associated with toothache in 12-year-old adolescents from the state of Minas Gerais in Brazil. Secondary data were collected from the SB Minas Gerais 2012 epidemiological survey. The dependent variable was toothache in the past 6 months. The independent variables were grouped into two levels: individual (sex, ethnic group, family income, periodontal condition, dental caries, dental treatment needs, and type of service used) and contextual (allocation factor, Human Development Index, Gini coefficient, gross domestic product, unemployment, illiteracy, basic sanitation, garbage collection, family income, half or a quarter of a minimum wage, primary healthcare coverage, primary oral healthcare team coverage, oral health technician, access to individual dental care, and supervised tooth brushing). A multilevel analysis was performed using the Hierarchical Linear and Nonlinear Modeling Software Program to assess the association of individual and contextual variables with toothache in the last 6 months. The prevalence of toothache in the last six months among the adolescents of this study was 19.1%. An association was found with family income (p <0.001), dental caries (p <0.001), primary oral healthcare team coverage (p = 0.015) and oral health technician (p = 0.008). Socioeconomic conditions and the most prevalent oral diseases, such as dental caries, as well as the use of public services, were related to toothache in adolescents aged 12 years. These findings reinforce the need to develop and implement public policies to address the oral health problems of this population.

RESUMEN Objetivo El objetivo del trabajo fue evaluar la tasa de mujeres embarazadas satisfechas con la consulta odontológica que realiza el Sistema Único de Salud-Brasil (SUS-Brasil) y factores asociados. Metodología Estudio de tipo transversal. Para colección de los dados se elaboró un cuestionario que abordaba las variables sociodemográficas y relacionadas con la gestación. La colección de los datos fue realizada por medio de entrevistas cara a cara en un hospital de maternidad de la región metropolitana del Porto Alegre, Brasil. Para comprobar la asociación de los factores con la satisfacción de las mujeres embarazadas con la consulta odontológica se usó el test de chi-cuadrado y la regresión del Poisson, con varianza robusta (p<0,05). Resultados De las 302 mujeres entrevistadas, 50% (n=151) realizaron consulta odontológica durante de la gestación y estas 86%(n=131) manifestaron estar satisfechas con la consulta. En el análisis multivariado se encontró que la variable que evaluaba las consultas prenatales como buenas aumentaba en un 14% [Razón de Prevalencia (RP)=1,14; Intervalo de Confianza (IC) del 95%:1,01-1,27] la probabilidad de que las mujeres expresaran satisfacción con la variable de resultado. Conclusiones Se concluyó que un alto índice de satisfacción con las consultas odontológicas realizadas en el SUS por parte de las embarazadas y la evaluación de las consultas prenatales como buenas fue un factor asociado. Estos resultados podrían ser considerados durante la planificación estratégica, ejecución y evaluación de las políticas de la salud pública direccionadas para este grupo operativo.

ABSTRACT Objective The study aimed to verify the rate of satisfaction among pregnant women with dental consults performed in the Brazilian Unified Health System (BUHS), and associated factors. Methodology The design of the study was cross-sectional. To collect data a questionnaire approaching variables sociodemographic and relationship whit pregnancy were used. The data gathering was realized across interviews face to face in a maternity hospital in the metropolitan region of Porto Alegre-RS-Brazil. The chi-square test and Poisson regression with robust variance (p<0.05) were used for the bivariate and multivariate analyses. Results A total of 302 pregnant women were interviewed, 50% (n=151) performed dental consults, and 86% (131) related that they were satisfied with the consult. In the multivariate analysis it was found that the variable evaluating prenatal visits as good increased the likelihood of women expressing satisfaction with the outcome variable by 14% [Prevalence Ratio (PR) =1.14; 95% Confidence Interval (CI): 1.01-1.27]. Conclusions The present study suggests that a high satisfaction rate with dental consult could be due to the highest satisfaction in prenatal consults performed in primary health care units, materializing the relationship of trust/connection between professional and user. This variable can be considered by workers and health managers during estrategic planning, performance, and evaluation of health policies.

Abstract The aim of this study was to assess the use and need of conventional removable prostheses (total and partial) and their associated factors among institutionalized elders. A cross-sectional study was conducted with 1003 elderly people living in non-profit private long-term care institutions in Belo Horizonte, Brazil. Inclusion criteria required a minimum Mini Mental State of Examination (MMSE) score of 21. After the test, 191 individuals were included. Oral examination and interviews were conducted to identify participants’ use (throughout the day/every day) and need (do not have/have but do not use) of removable dental prostheses. Socioeconomic health indicators and behaviours were collected from institutional records and via interviews. Bivariate analysis was performed using chi-square test (p<0.05). Poisson regression with robust variance was used in multivariate analysis. Most elders were female (76.4%) and independent in their daily activities (56.5%). Elderly men (PR 1.26) and those whose dental visit was more than one year ago (PR 1.38) showed higher need of dental prostheses. Elderly women (PR 1.68) and individuals with morbidities (PR 1.33) had higher prostheses use. This study demonstrates how socio-demographic characteristics, health indicators, and oral health services impact the use and need of dental prostheses among elders and how these can contribute to public oral health policy development.

Abstract The aim of this study was to assess the factors associated with dental pain in adolescents from the state of Minas Gerais, Brazil. Individual data on adolescents aged 15 to 19 years were collected from the SB Minas survey secondary database. Dental pain over the past 6 months, assessed by a questionnaire, was used as the dependent variable. Sex, income, skin color, prevalence of untreated dental caries, periodontal health, dental treatment needs, and time of last dental appointment were analyzed as individual covariates. Allocation factor, Human Development Index (HDI), Gini coefficient, illiteracy rate, unemployment, 50% and 25% of the Brazilian monthly minimum wage, primary healthcare coverage, oral health team coverage, access to individual healthcare, and supervised toothbrushing average rate were the analyzed contextual variables. A multilevel analysis was conducted for the individual and contextual variables. Statistical analyses used hierarchical linear and nonlinear modeling to infer an association between the different levels. Male adolescents had a lower prevalence of dental pain (OR = 0.53; 95%CI = 0.37–0.75). There was an association between dental pain and low income (OR = 1.58; 95%CI = 1.07–2.33), prevalence of untreated dental caries (OR = 1.25; 95%CI = 1.11–1.40), periodontal health (OR = 1.80; 95%CI = 1.04–3.09), and dental treatment needs (OR = 6.93; 95%CI = 3.96–12.14). Sociodemographic and clinical factors at the individual level were associated with the outcome but not with contextual variables. These findings reinforce the need to address these factors for effective community health actions.

Abstract This study aimed to identify the prevalence of molar-incisor hypomineralization (MIH) in schoolchildren and its association with dental caries experience. This was a cross-sectional study with a sample of 471 children aged 8 to 10 years. Data were collected via a sociodemographic questionnaire. Intra-oral clinical examination was done to identify and diagnose MIH (EAPD Criteria) as well as dental caries (ICDAS Index). Statistical analyses were performed with Person’s Chi-square, Fisher’s exact, and Mann-Whitney tests, and Poisson regression models were built. Statistical significance was set at an alpha-level of 0.05. The prevalence of MIH in our participants was 9.8%, with lesions being mostly of the mild form (65.2%) and affecting the first permanent molars but not the incisors in 54.2% of the children. Dental caries was observed in 88.1% of subjects. We observed a significant association between dental caries and the following variables: presence of MIH (p < 0.01; PR = 1.13), dental visit (p < 0.02; PR=0.92), and parents or legal guardians’ education level (p < 0.05; PR = 1.07). A MIH diagnosis was also significantly associated with family income (p < 0.05; PR = 4.09). Children with MIH had more caries lesions on molar surfaces (p < 0.01; PR = 4.05). The prevalence of MIH was found to be moderate, based on previous studies, and the presence of enamel defect was associated with dental caries. The teeth most affected by MIH lesions were the first permanent molars.

Abstract The aim of this study was to investigate the intraoral distribution of untreated caries and tooth loss and estimate the impact of different socioeconomic factors on the occurrence of these outcomes. A cross-sectional study was conducted with 652 18-year-old male adolescents from the city of Sapucaia do Sul, Brazil, who conscripted for military service. The participants answered a questionnaire addressing sociodemographic variables. Two trained and calibrated examiners performed the clinical examinations for the diagnosis of dental caries using the criteria of the World Health Organization. Tooth group and adolescent were the units of analysis for the primary outcomes of the study. Poisson regression analysis with robust variance was performed, with the calculation of crude and adjusted prevalence ratios (PR) and 95% confidence intervals (CI). The prevalence of caries experience and untreated caries was 70.2% and 39.3%, respectively, and 9.4% of the adolescents had missing teeth. Sixty-seven percent of the untreated caries and 98.8% of missing teeth were in first molars. The probability of dental caries and tooth loss was significantly higher among adolescents with less schooling (PR = 2.56; 95%CI: 1.97–3.32 and PR = 3.28; 95%CI: 1.61–6.65, respectively) and those whose mothers had less schooling (PR = 1.31; 95%CI: 1.03–1.67 and PR = 2.30; 95%CI: 1.18–4.50, respectively). In conclusion, the occurrence of untreated dental caries and tooth loss was concentrated in the first molars of adolescents. Moreover, the prevalence of both conditions was higher among adolescents with low schooling and whose mothers had low schooling, reflecting the strong intraoral and socioeconomic polarization of these outcomes.

AIM: To identify a possible association between the occurrence of dental caries and tooth erosion and to correlate the dietary factor with an increased risk of dental caries. METHODS: A cross-sectional study in a multistage random sample of 1,211, 8 to 12-years-old Brazilian schoolchildren in private and public schools was conducted in Pelotas, Brazil. The prevalence of dental caries and tooth erosion was assessed. Dietary habits data were collected by a structured questionnaire. Data were analyzed using Poisson regression model taking into account the cluster sample (Prevalence ratio - PR; 95% Confidence Interval - CI). RESULTS: The prevalence of dental caries and tooth erosion was 32.4% (95% CI: 30.0; 35.2) and 25.0% (95% CI: 23.4; 29.0), respectively. Most children had high consumption of sweets (65%). Consumption of fruits, such as oranges (31%), strawberries (23.6%), pineapple (12%), and natural fruit juices (oranges, lemon) was low. Soft drinks consumption, 3 or more times a week was observed in 40% of the children. CONCLUSIONS: Dental caries was not statistically associated with tooth erosion. The consumption of acidic fruits/drinks was not associated with dental caries. Dental caries and dental erosion were not associated with each other and with acidic fruits or drinks consumption.

As crianças foram entrevistadas, fornecendo informações demográficas, comportamentos de saúde bucal e prática de atividade física. Exame de saúde bucal foi realizado e medidas antropométricas aferidas para avaliação da condição nutricional. Diretores das escolas forneceram informações sobre o ambiente físico e social das escolas. Das 1.744 crianças elegíveis, a taxa de resposta foi 69,4% sem diferenças entre escolas. A metodologia proposta permitiu a obtenção de dados sobre diversos desfechos de saúde bem como sobre possíveis fatores de risco. Esta estratégia otimiza recursos financeiros de pesquisa e favorece a colaboração interprofissional.

This paper describes the methods of a multidisciplinary epidemiological survey conducted in schools in Pelotas, in the Southern Region of Brazil. This cross-sectional study evaluated a representative sample (n = 1,211) of eight to 12-year-old children attending public (15) and private (5) schools. Questionnaires were applied to parents to obtain information about socioeconomic and sociocultural characteristics. Children were interviewed to provide information on demographic characteristics, oral health behavior and physical activity habits. Oral health examinations were performed on the children and anthropometric data was collected to assess nutritional status. School principals responded a questionnaire about the social and physical environment of the school. A total of 1,744 children were eligible for the study; a response rate of 69.4% was achieved, with no significant differences between schools. The method used allowed investigators to obtain data on several health outcomes as well as on possible risk factors. This strategy optimizes the use of financial resources for research and promotes interprofessional collaboration.

O carcinoma espinocelular (CEC) de boca é o quinto mais comum no mundo. O efeito de alguns fatores etiológicos está bem estabelecido na literatura, como o fumo e o consumo de álcool. No entanto, aproximadamente 15 a 20% dos casos de câncer bucal acometem pacientes sem os tradicionais fatores de risco e isso se traduz em inúmeros casos de CEC bucais em indivíduos não fumantes e não etilistas. Além disso, dados da literatura têm sugerido uma possível associação entre o vírus papiloma humano (HPV) e o carcinoma espinocelular de boca. Em virtude desse aspecto, desenvolveu-se este trabalho na perspectiva de revisar as características mais associadas a esse grupo de pacientes, contribuindo assim para a melhoria no diagnóstico e no acompanhamento dos mesmos. Os artigos que serviram de apoio para o estudo foram localizados por meio da base de dados Pubmed, utilizando os descritores "epidemiologia", "carcinoma espinocelular de boca", "fatores de risco" e "vírus papiloma humano". É importante avaliar pacientes sem tais fatores de risco, uma vez que o conhecimento pode auxiliar na análise de outras características associadas com a ocorrência de carcinoma. Além disso, possibilita melhorar o manejo clínico e monitoramento.

Oral squamous cell carcinoma (OSCC) is the fifth most common type of cancer in the world. The effect of some etiological factors is well established in the literature, such as consumption of tobacco and alcohol. However, approximately 15 to 20% of all oral cancer cases occur in patients without the traditional risk factors, reflecting in numerous cases of OSCC in non-smokers and non-alcoholic drinkers. Also, several studies have suggested a possible association between human papillomavirus and OSCC. Under these aspects, the purpose of this study is to address cases of oral cancer in non-smokers and non-drinkers focusing on the role of HPV, thus contributing to improve the diagnosis and monitoring of OSCC. A computer database search was performed using the Pubmed database. The search key words were: epidemiology, oral squamous cell carcinoma, risk factors and human papillomavirus. It is important to assess patients without the potential risk factors, since this knowledge may help identifying other features associated with the occurrence of oral cancer, enabling an appropriate clinical management and monitoring.
