Objective: The propose of this study was to estimate the prevalence of malocclusion
among adolescents and to assess the differences of this prevalence according to sex, experience
of caries, gingival bleeding, and smile dissatisfaction. Methods: A cross-sectional study was
conducted with 600 adolescents from 10 to 16 years old, who were identified and selected from
public schools’ records. Intraoral and extraoral examinations were performed following World
Health Organization recommendations and included: number of decayed, missing and filled
teeth, presence of gingival bleeding, and occlusal condition. The latter was assessed based on
information of Dental Aesthetic Index, and Foster and Hamilton Index, in addition to the
evaluation of dental midline, facial and smile pleasantness according to Capelozza Filho
classification. Smile dissatisfaction was also evaluated. Bivariate Poisson regression with robust variance was used to compare prevalence rates. Results: The prevalence of
malocclusion, caries experience, gingival bleeding and smile dissatisfaction were 96.0%,
52.3%, 55.8%, and 49.4%, respectively. The prevalence of malocclusion was higher among
adolescents with gingival bleeding. Statistically significant associations were noticed between
crowding of the upper and lower anterior teeth and gingival bleeding, as well as among Class
III molar relationship, deviation of the dental midline, anterior open bite, anterior crossbite, and
caries experience. Smiles classified as acceptable or unpleasant were associated with
dissatisfaction. Conclusion: These findings have evidenced a higher prevalence of
malocclusion among adolescents and its association with caries experience, gingival bleeding,
and smile dissatisfaction.
