The objective of this research was to verify the association between verbal bullying and untreated dental caries. The present cross-sectional study had a representative sample of 1,589 children, aged 8-10 years, from public schools. Information on verbal bullying related to the oral condition was obtained through a questionnaire directed to the students. Clinical data were collected by 4 calibrated examiners (kappa > 0.70) using the DMFT/dmft and PUFA/pufa indexes for caries. Socioeconomic issues were answered by those responsible. The prevalence of verbal bullying related to the oral condition was 27%. The results of the Poisson regression, in an adjusted multiple model, showed a significant association between bullying and untreated caries lesions (prevalence ratio, PR: 1.27; 95% CI: 1.07-1.52), PUFA/pufa index (PR: 1.34; 95% CI: 1.11-1.61), pulp involvement (PR: 1.35; 95% CI: 1.09-1.67), and abscess (PR: 1.74; 95% CI: 1.18-2.56). It was concluded that children with untreated dental caries had a higher prevalence of verbal bullying when compared to caries-free or disease-treated children.

Aim To assess the prevalence of self-reported dental pain and its association with sociodemographic, clinical and behavioral/psychosocial indicators among 8- to 10-year-old Brazilian schoolchildren. Design A cross-sectional study was carried out with 1,589 eight- to ten-year-old children randomly selected from public schools of Florianopolis, Brazil. Self-reports of dental pain were collected through a single question as follows: “In the last month, how many times have you had pain in your teeth?” Caries experience was determined by the DMFT/dmft index and its clinical consequences by the PUFA/pufa index. Dental trauma, dental fluorosis and molar-incisor hypomineralization were assessed through the Andreasen, Dean and European Academy of Pediatric Dentistry classifications, respectively. Clinical signs of dental erosion were also observed. Sociodemographic indicators were obtained through a questionnaire answered by the children’s caregivers. Information about behavioral/psychosocial indicators was collected through questions from the Brazilian version of the Child Perception Questionnaire 8–10 years (CPQ 8–10 ). Descriptive analysis, chi-square test, and hierarchically adjusted Poisson regression models were performed. Results 819 children (51.5%) reported episodes of dental pain in the last month prior to the study, whereas 55.6% (n = 509) were girls. The presence of dental pain was significantly associated with sex, trouble sleeping, difficulty eating, school absenteeism, difficulty with paying attention in class, difficulty doing homework, staying away from recreational activities, caries experience, PUFA/pufa index and ulceration (p<0.05). Conclusion The prevalence of self-reported dental pain in 8- to 10- year-old Brazilian schoolchildren was high and was associated with sociodemographic, clinical and behavioral/psychosocial indicators.

Enamel fracture had no significant impact on children's quality of life, while enamel-dentin fracture did have an impact on quality of life.

Objective: To evaluate the impact of dental trauma and impaired esthetics on the quality of life (QoL) of preschool children and their relatives.Methods: Study conducted with 192 children aged 2 to 5 years in 11 preschools in Florianópolis, Santa Catarina, South of Brazil. Parents/caregivers completed a questionnaire on quality of life (Brazilian version of the Early Childhood Oral Health Impact Scales - B-ECOHIS), a socioeconomic survey, and then answered specific questions related to dental trauma. The subjects were examined by three accordant examiners (Kappa>0.7). Dental trauma was evaluated on the basis of indexes adopted by the World Health Organization, and esthetic impairment was then classified. Data were descriptively analyzed and put to bivariate analysis by chi-square and Fisher tests, with significance level at 5%.Results: The prevalence of dental trauma was 62.5% with 15.6% of esthetic impairment. Almost 12% of parents reported impact on the quality of life of their children. Dental trauma was not significantly associated with gender, age or QoL. Crown color change by trauma was associated with esthetic impairment. Also esthetic impairment had a negative impact on QoL (p<0.05) and was associated with oral limitations (p<0.05). Conclusions: Esthetic impairment had a negative impact on children’s quality of life, while dental trauma was not associated to it.
