Determination of dental caries, molar-incisor hypomineralization, and oral health-related quality of life in schoolchildren: A structural equation modeling approach.

Background: Some oral conditions can have psychosocial consequences that affect children's daily life and well-being.

Aim: To create a structural model for the determination of dental caries, molar-incisor hypomineralization (MIH), and the impact of these conditions and socioeconomic status on schoolchildren's oral health-related quality of life (OHRQoL).

Design: A representative cross-sectional study was conducted in Lavras, Brazil, with 1181 female and male schoolchildren 8-9 years of age.

Association Between Probable Awake Bruxism and School Bullying in Children and Adolescents: A Case-Control Study.

The purpose of this study was to evaluate the association between probable awake bruxism (PAB) and school bullying in children and adolescents. A total of 380 children and adolescents enrolled in public and private schools in the city of Lavras, Minas Gerais, Brazil, participated in this case-control study. The case group (190 children with PAB) and the control group (190 children without PAB) were matched for sex and age.

Association between possible awake bruxism and bullying among 8- to 11-year-old children/adolescents.

Background: Bruxism is characterized by tooth grinding and/or clenching.

Aim: To evaluate the association between possible awake bruxism (PAB) and bullying among individuals aged 8-11 years.

Design: A representative cross-sectional study was conducted with 434 eight- to eleven-year-old children/adolescents.

Association between Molar Incisor Hypomineralization in Schoolchildren and Both Prenatal and Postnatal Factors: A Population-Based Study.

Background: Although studies throughout the world have investigated potential factors involved in the occurrence of molar incisor hypomineralization (MIH), the findings are varied and inconclusive.

Objective: The aim of the present study was to evaluate the prevalence of MIH and identify associated prenatal, perinatal and postnatal factors among Brazilian schoolchildren aged 8 and 9 years.

Methods: A cross-sectional study was conducted with a randomly selected population-based sample of 1181 schoolchildren.
