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.

Cleft lip and cleft palate are birth defects of complex etiology. The aim of this study was to evaluate the occurrence of cleft lip and palate in Brazilian children. An ecological and descriptive study, based on data from the Live Birth Information System (SINASC / DATASUS) between years 2011 and 2015 in the cities of João Pessoa, Campina Grande, Patos, Cajazeiras, and Sousa (State of Paraíba) was developed. Information on the presence of congenital anomalies and cleft lip and palate, gender of neonate, birth-weight (<2.5kg and ≥2.5kg) and mother's age were collected. Data were tabulated with Microsoft Excel software and presented through descriptive statistics (absolute and percentage distributions). In the study period, there were 206367 cases of live birth, with 1916 cases of children with congenital anomalies of which 109 (5.7%) had cleft lip and palate, predominantly males (66%). Regarding birth-weight, 27.5% had <2.5kg. The majority of mothers aged 20-29 years (45.9%). The city of Campina Grande concentrated the highest number of cases (50.5%), with prevalence of 7.36 cases per ten thousand live births. The frequency of cleft lip and palate was 5.2 per 10000 live births. Male children with normal birth-weight are the most affected by cleft lip and palate.

To estimate the prevalence of dental fear in schoolchildren and verify its association with gender, age group and oral health habits. Cross-sectional study with 44 elementary students from public schools. Data on sociodemographic issues and children's oral health habits were collected and the Children’s Fear Survey Schedule - Dental Subscale (CFSS-DS) questionnaire was applied. Descriptive analysis of the data was performed, Fisher's Exact and U Mann-Whitney tests (p <0.05). The prevalence of dental fear was 6.8% and the average of the total score of the CFSS-DS was 26.43 ± 7.20, median of 24.50, IQR25-75 21-33, minimum score of 16 and a maximum of 42. Most children had a low level of dental fear (95.5%). The levels of dental fear did not show statistically significant associations between sex (p = 0.162), age group (p = 0.181), having visited the dentist once in life (p = 0.201), complaints of tooth pain (p = 0.522) and complaints of tooth sensitivity (p = 0.181). The prevalence of dental fear was low and most children had a low level of dental fear. There was no association between dental fear and the variables sex, age, having visited the dentist at any time in life, complaints of pain and complaints of dental sensitivity.

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 (p<0.001), strict diet (p<0.001), fasting for 24 hours (p<0.001), self-induced vomiting (p<0.001), and BMI (p<0.001). There was also a statistically significant difference between behavioral risk and the presence of dental caries (p<0.05) and erosion (p<0.001). 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.

Objective: To assess the relationship between the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) questionnaire’s items and sex and age in children with moderate and high dental fear levels. Methods: Cross-sectional study carried out in a municipality in the Northeastern region of Brazil with 185 children aged 8-10 years of both sexes, who had a minimum score of 32 on the CFSS-DS questionnaire, corresponding to dental fear. Descriptive statistical analysis and the Kolmogorov-Smirnov, Mann-Whitney U, and Kruskal-Wallis tests were performed. The significance level adopted was 5%. Results: Most children were female (59.5%) and 9 years old (37.3%). The average of the total CFSS-DS score was 40.44 ± 6.81 (with a minimum of 32 and a maximum of 75). According to the CFSS-DS, 53.5% of children had high dental fear. Items “Injections,” “Having a stranger touch you,” “The dentist drilling,” “Having somebody put instruments in your mouth,” “Choking,” and “Having to go to the hospital” had the highest median values. A significant difference was observed between ages for the item “Having a stranger touch you” (p=0.001). Conclusion: The item “Having a stranger touch you” in the CFSS-DS questionnaire showed a statistically significant difference with age, while no differences were found regarding sex.
