Background: Aesthetic alterations in the face can be self-perceived and can affect quality of life. For young people,
physical attractiveness is an important factor affecting social relationships. The aim of this study was to estimate the
prevalence of malocclusion, identify the most common types and test its association with oral aesthetic
self-perception in 18 to 21 year-old population of male young adults.
Methods: A cross-sectional study was carried out involving 138 Brazilian Army soldiers. Data collection included
socio demographic profile, malocclusion status through the Dental Aesthetic Index (DAI) and oral aesthetic
self-perception as indicated by the Oral Aesthetic Subjective Impact Scale (OASIS). The chi-square and Fisher’s exact
test were used to test for homogeneity of proportions. The stepwise multivariate logistic regression analysis was
used to test for the relationship between the poorer oral aesthetic self-perception and parental and soldier’s
education, per capita income, history of caries in all teeth and only on anterior teeth, dental trauma, previous
orthodontic treatment and malocclusion.
Results: The prevalence of malocclusion was 45.6%. Incisor teeth crowding and misalignment of lower incisors
were the most common types of malocclusions. A statistically significant and independent association between
malocclusion and poorer oral aesthetic self-perception in the multivariate analysis was observed. Subjects with
severe malocclusion conditions showed 88% higher prevalence [prevalence ratio =1.88 (95% CI, 1.30 – 2.72); p =
0.001] of poorer aesthetic self-perception comparing to those with minor malocclusion.
Conclusions: A high prevalence of malocclusion was observed. The young adults presenting severe malocclusion
had a higher and independent prevalence of poorer oral aesthetic self-perception.
