Objectives: To evaluate the efficacy of resin infiltrants (RIs) in controlling non-cavitated occlusal carious lesions (NCOCLs) in primary and permanent teeth. Methods: This systematic review followed PRISMA guidelines. Randomized clinical trials (RCTs) and in vitro/ex vivo studies comparing RI with placebo or other materials were included. Searches were conducted in five databases and gray literature up to December 2025. Risk of bias was assessed using the RoB 2.0 tool for RCT and an adapted instrument for in vitro/ex vivo studies. Certainty of evidence was evaluated using the GRADE tool, and data were synthesized qualitatively. Results: Eight studies were included, of which only two were RCTs, and six were in vitro and ex vivo studies. RCTs showed reduced caries progression in infiltrant-treated groups compared with controls, with efficacy comparable to conventional sealants. In vitro studies demonstrated improved resin penetration and sealing ability with optimized protocols. Risk of bias ranged from low to moderate. Certainty of clinical evidence was low, primarily due to the limited number of RCTs and methodological limitations. Conclusions: RIs may be effective in managing NCOCLs, with performance comparable to conventional preventive approaches. However, the limited number of clinical trials and short follow-up periods reduce the strength of the evidence. Long-term clinical studies are needed to confirm the sustained effectiveness and durability of RIs.

Objective: To evaluate the psychometric properties of a self-administered oral health literacy (OHL) questionnaire for adolescents, titled the Brazilian Oral Health Literacy-Youngs Questionnaire (BOHL-YQ). Methods: The study included adolescents aged 15 to 19 years enrolled in public schools in the municipality of Araruna, Paraíba, Brazil. Data on demographic, socioeconomic characteristics, and oral health-related behaviors were collected from 360 participants. The internal consistency of the BOHL-YQ was evaluated. To examine the dimensional structure of the instrument, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. Convergent validity was investigated through associations between BOHL-YQ scores and demographic, socioeconomic, and oral health-related behavioral variables. Results: A total of 348 questionnaires were analyzed. One item showed inadequate loading in the EFA of the 15-item version. The EFA of the 14-item version demonstrated good internal consistency (Cronbach’s alpha=0.71; McDonald’s omega=0.72), a Kaiser-Meyer-Olkin value of 0.77, and adequate fit for two domains: Cognitive and Comprehension/Decision-Making. The CFA indicated the model explained 84% of the variance. Higher OHL scores were found among female adolescents (p=0.006), urban residents (p9 years of schooling (p=0.014), did not receive government benefits (p<0.001), had a dental visit within the last year (p<0.001), and in private dental services (p=0.043). Conclusion: In this context, the BOHL-YQ demonstrated good internal consistency and convergent validity, indicating that it is a valid and easily applicable instrument for measuring oral health literacy among Brazilian adolescents.

Objetivo: Analisar e mapear índices do flúor em águas in natura do município de Igaracy-PB. Método: As amostras foram coletadas em recipientes de plástico num volume de 500ml. Após a coleta as amostras foram armazenadas em recipientes térmicos até seu transporte para o Laboratório de Biologia do Meio Bucal (LABIAL) e o Laboratório de Química e Bioquímica da UEPB. Um eletrodo flúor-íon-específico e um potenciômetro foram usados para medições de flúor. Curvas de calibração foram executadas, usando amostras padrão conhecidas, contendo entre 0,4 a 6,4 mg / L de flúor. Tanto as soluções-padrão como as amostras de águas foram adicionadas ao Total Ionic Strength Adjusting Buffer II. As leituras em milivolts foram convertidas para concentração iônica de flúor por meio de uma curva padrão de correlação. Resultados: Os teores de flúor encontrado nas amostras variaram de 0,12 mg/L a 1,13 mg/L, onde aproximadamente 10% das amostras testadas apresentaram valor superior a 1mg/L. E o pH das amostras variaram de 5 a 9. Embora, os valores encontrados estejam abaixo da portaria vigente 2914/2011 do Ministério da Saúde, há uma preocupação do valor próximo ao limite. Conclusão: Com base nos resultados, todos os pontos testados apresentavam-se dentro dos valores normativos, porém 10% da amostra apresenta-se próximo do limítrofe, sugere-se então novos experimentos nesse local próximo ao limite, para possível averiguação.

To analyze the impact of oral health conditions on quality of life and daily activities among adolescents according to the Oral Impacts on Daily Performances (OIDP) and its domains. This cross-sectional study was based on data from the Brazilian National Oral Health Survey (SB Brasil 2023) and included 8,054 adolescents aged 15 to 19 years from all regions of the country. The outcome was oral health-related quality of life assessed using the OIDP instrument. Associations between OIDP and its domains with the presence of untreated caries, tooth loss, odontalgia, need for prostheses, gingival bleeding, and dental calculus were analyzed. Statistical analyses were performed considering the complex sample design, using the Rao-Scott adjusted F-test and multiple logistic regression considering a 95% confidence interval (CI). A negative impact of oral health on quality of life was observed in 37.2% of adolescents, with a higher frequency among those with lower family income and education level. All oral health problems analyzed showed a significant association with an OIDP≥1. After adjusting for sociodemographic factors, dental pain in the last 6 months was the condition most strongly associated with a negative impact on quality of life (OR=9.06; 95%CI 6.32-13.0), followed by the need for a prosthesis (OR=3.86; 95%CI 2.31-6.43), untreated dental caries (OR=2.39; 95%CI 1.87-3.05), tooth loss (OR=1.56; 95%CI 1.07-2.26), gum bleeding (OR=1.62; 95%CI 1.14-2.29), and dental calculus (OR=1.33; 95%CI 1.03-1.71). Oral health problems represent a limiting factor in the quality of life and daily activities of Brazilian adolescents.

Objective To describe the distribution profile of untreated dental caries in Brazilian adolescents, using the PUFA index, and identify the main associated factors. Methods: This is a cross-sectional study based on data from the 2023 National Survey of Oral Health. The sample consisted of 8,053 adolescents aged 15 to 19 years. The dependent variable was the presence of untreated caries, measured by the PUFA index. Independent variables included sociodemographic and oral health-related factors such as impacts on quality of life and access to dental services. Descriptive and bivariate analyses were performed using the Rao-Scott test and multiple logistic regression, considering a significance level of 5% (p<0.05). Results: We verified that 12.5% of Brazilian adolescents had at least one tooth affected by some repercussion of untreated caries. There were statistically significant associations between PUFA≥1 and the adolescents’ socioeconomic conditions, such as lower level of education, low family income, being beneficiary of government cash transfer programs, in addition to Black skin color/race. We observed a negative impact on the quality of life of 22.4% of adolescents with PUFA index ≥1, and 19.1% had never had a dental appointment. Low family income, presence of pain in the last six months, and self-perceived need for dental treatment were factors strongly associated with PUFA≥1. Conclusion: Social determinants influenced the progression of dental caries in adolescents. Therefore, social policies targeting Black adolescents and expanded access to dental services are essential to reduce oral health problems in this more vulnerable population.
