Abstract

Objective: To investigate the prevalence, severity, and need for treatment of malocclusions and their impact on the oral health-related quality of life (OHRQoL) in 12-year-old teenagers.

Materials and methods: Cross-sectional study performed with 453 adolescents. Malocclusion was evaluated using the Dental Aesthetics Index (DAI), and Child Perception Questionnaire11-14 (CPQ11-14) was used to assess the OHRQoL. CPQ11-14 scores were compared according to gender and presence of malocclusion using Mann-Whitney test. Analysis according to the severity of malocclusion was performed using Kruskal-Wallis test.

Results: The prevalence of defined or higher malocclusion was 53.86% while very severe or disabling malocclusion with essential need for treatment was observed in 18.76%. There was a positive correlation (r=0.7006; p<0.0001) between the DAI and CPQ11-14 scores. Adolescents with malocclusion had higher total CPQ11-14 scores (p<0.05) as well as emotional and social well-being domains scores than those without malocclusion. The total CPQ11-14 score was higher (p=0.0251) in women (16.91+10.52) than in men (14.61+9.70).

Conclusion: The prevalence of malocclusion was high, with a predominance of defined malocclusion requiring elective treatment. Malocclusion had a negative impact on the OHRQoL, especially regarding the emotional and social aspects.
