Background: Eating disorders are complex conditions that cause serious emotional and physical problems. Aim: The aim of the study was to evaluate the behavioral risk for eating disorders in Brazilian female adolescents and their association with dental caries and erosion. Materials and Methods: This cross-sectional study included 200 students from public and private schools aged 15-18 years divided into two groups according to behavioral risk: Group 1 - adolescents without risk and Group 2 - adolescents at risk / disorder situation. Sociodemographic information (age and type of school), use of dental services, eating habits, and Body Mass Index (BMI) was obtained. The Bulimic Investigatory Test of Edinburgh (BITE) was used to identify behavioral risk. Caries experience was assessed using the DMFT index, while dental erosion was evaluated using the O'Sullivan index. Data were analyzed using descriptive and inferential statistics, with a significance level of 5%. Results: The highest overweight and obesity percentages were verified among adolescents at risk / disorder, respectively, 33% and 16%. There was a statistically significant association between behavioral risk and variables standard dietary pattern (ppppppp Conclusion: Behavioral risk for eating disorders in female adolescents was associated with standard dietary patterns, strict diet and, self-induced vomiting. Adolescents at risk / eating disorders for bulimia were related to dental caries and erosion.

Aim. To assess the impact of incisor molar hypomineralization (MIH) on oral health-related quality of life (OHRQoL) according to the perception of students and their parents/caregivers. Materials and Methods. This is a cross-sectional population-based study with 463 Brazilian students aged 11–14 years. OHRQoL was measured using the Child Perceptions Questionnaire (B-CPQ11-14ISF: 16) applied to students and the short version of the Parental-Caregiver Perceptions Questionnaire (B-P-CPQ) applied to parents/caregivers. The diagnosis of MIH followed the European Academy of Paediatric Dentistry criteria modified in 2019. Caries experience (ICDAS II), malocclusion (DAI), and socioeconomic and demographic factors were assessed as confounding factors for impact on OHRQoL. Cluster analysis was carried out to dichotomize the negative impact into greater and lesser impact. The chi-square test and Poisson regression were performed ( p < 0.05 ) to verify associations between quality of life and MIH, adjusted for confounding variables. Results. The prevalence of MIH was 10.8%. Multivariate regression demonstrated that caries experience was the only oral disease that impacted OHRQoL according to students’ self-perception in the functional limitation domain (PR = 1.82; 95% CI = 1.20–2.77) and in the total questionnaire score (PR = 1.59; 95% CI = 1.00–2.51). However, according to the perception of parents/caregivers, in addition to caries experience, which affected OHRQoL in the oral symptoms (PR = 3.57; 95% CI = 1.71–7.414) and emotional well-being domains (PR = 1.71; 95% CI = 1.08–2.69), as well as in the total B-P-CPQ score (PR = 1.67; 95% CI = 1.01–2.76), malocclusion also affected OHRQoL in the social well-being domain (PR = 1.50; 95% CI = 1.07–2.10) and in the total questionnaire score (PR = 1.54; 95% CI = 1.11–2.15). Conclusion. According to students and their parents/caregivers’ perception, incisor molar hypomineralization did not influence OHRQoL of the studied sample.
