Can visual stimuli from media influence perception of dentofacial esthetics? A randomized controlled trial

Objectives: The study explored whether television commercials change the perception of one’s own dentofacial attractiveness and to identify if it is influenced by personality traits. Material and methods: The sample included 83 participants, aged 19-27 years. The experimental group (N=42) watched commercials portraying famous young individuals with high smile esthetics, bright teeth and no visible malocclusions, while the control group (N=41) watched neutral commercials (without people or visible teeth). The perception of subjects` own orofacial esthetics and its psychosocial effects were assessed a month before the exposure and immediately after it. The subjects` malocclusion severity and personality characteristics (extraversion, conscientiousness, agreeableness, neuroticism, in-tellect, self- esteem and perfectionism) were assessed. Results: In their second report, respondents were inclined to report less psychosocial impacts with small differences (ranging from 0-3 scalar points on average) and less significant in the active group compared to neutral group (2 out of 7 vs. 5 out of 7 aspects). Types of visual stimuli were a significant predictor only of changes pertaining to psychological impact of dental esthetics (p=0.045 ; r=0.221). The intellect moderated perception of smile esthetics, after having been exposed to commercials, accentuated beautiful smiles as a suppressor (ΔR 2 =0.076 ; p=0.005 ; total model R 2 =0.347 ; p=0.033). In subjects with higher cognitive abilities, an increase in the self- perceived malocclusion level induced a smaller decrease in psychological impact of dental esthetics as compared to those with lower intellect. Conclusion: Psychosocial influences of malocclusion are not stable and tend to decrease during time. However, the exposure to a high smile esthetic of other individuals can inhibit that process in persons with more severe mallocclusion and higher cognitive abilities.
