Traços de personalidade, impacto psicossocial,qualidade de vida e auto percepção de estética de pacientes submetidos ao clareamento dentário

Abstract

The objectives of this study were to determine whether is there influence of personality in the choice of aesthetic treatments, measure the perception of orofacial aesthetics, verify if tooth whitening can promote changes in quality of life and changes in personality traits, perform a Portuguese version of the Oral Esthetic Scale (OES) and evaluate its psychometric properties. In first study, 128 patients were selected for performing dental bleaching, however, 70 accepted while 58 of these refused treatment. Patients of both groups were evaluated through NEO-FFI, to evaluate their personality traits. For each domain comparison, Mann-Whitney test was used and for comparison between domains before and after bleaching was it used Wilcoxon. There was prevalence of Extraversion domain in patients who accepted treatment (p = 0.01), among the evaluations there was no statistically significant difference (P> 0.01). In study 2, 63 patients received dental bleaching and were evaluated for their personality traits (NEO-FFI-R), aesthetic perception (PIDAQ) and quality of life (WHOQOL-bref). All questionnaires were applied previously and after treatment. A descriptive analysis was performed about demographics characteristics and Pearson correlation was performed to evaluate any statistically significant difference between the group data. The internal consistency of the test was assessed by Cronbach's Alpha. The domain data changes of the tests were evaluated by Wilcoxon Signed Rank (α = 0.05). There was no statistically significant difference between personality traits before and after treatment and quality of life, however, it was found predominance of patients with higher scores in Extraversion domain. In study 3, an instrument for evaluating aesthetic perception (OES) was translated into Portuguese. The OES was translated, adapted and a new version was called EEO. At this stage, 151 patients participated. The reliability was assessed by Cronbach's alpha, the intraclass correlation was assessed (α = 0.05) and the size of the effect was evaluated (Cohen´s d). Convergent, discriminant, and factorial validity were also checked. The EEO showed similar characteristics to the original questionnaire and has satisfactory psychometric properties for evaluation of orofacial aesthetics.
