This observational, cross-sectional study compared 2 groups (experimental vs control) of patients recruited at an outpatient orthodontic clinic. Oral health-related quality of life was assessed using a short form of the Oral Health Impact Profile, self-esteem was evaluated with the Rosenberg Self-Esteem Scale, and depression symptoms were assessed using the General Hospital Depression Scale (outcome variables). The presence of dentofacial deformities (ie, group allocation) was the primary predictor variable. The ¦Ö<sup>2sup> test and Spearman correlation coefficient were used to analyze data.
The total sample was composed of 68 individuals (34 in each group). In the experimental group, 55.9 % of patients were women, and 88.2 % presented a Class III occlusal relation. The mean age in the experimental group was 27.56 years. Significant differences were observed between the 2 groups in oral health-related quality of life (P < .001) and self-esteem (P < .019), but no differences were found for depression (P = .161).
Patients with dentofacial deformities had a more negative oral health-related quality of life and a lower self-esteem compared with controls. No association was observed between dentofacial deformities and depression.
