title: Oral Health-Related Quality of Life and Associated Factors in Brazilian Adolescents.
abstract: This study aimed to assess the impact of oral health on the quality of life of adolescents. A cross-sectional study was performed with students from public and private schools from Passo Fundo, Brazil. All students were aged between 15 and 19 years old. The proportional random sample consisted of 736 adolescents from 20 schools. A structured questionnaire was applied, and an oral examination was performed, counting the number of teeth. Oral health-related quality of life was assessed by OHIP-14. Associations between quality of life and associated factors were analyzed. The mean OHIP-14 score was 7.25. Age, ethnicity and studying in a public school were associated to the OHIP-14 score. Tooth loss (p=0.79) was not associated with quality of life. Additionally, questions related to appearance, such as whether teeth appearance bothers the adolescent (p=0.68) were not associated with quality of life. Attending a public school (OR=1.63; CI95%: 0.98-2.70) and self-reported halitosis (OR=1.48; CI95%: 1.01-2.16) were strongly associated to higher impact on quality of life. It was concluded that socioeconomic conditions and halitosis were associated to higher impact on quality of life of adolescents.
