The mass media to some extent influence the perception. The aim of this study was to investigate the extent to which advertisements are changing the perception of their own aesthetics. In addition to what extent the relationship is determined by clinical state and whether this influence personality traits, sex and age. By design the research was a randomized controlled trial. The study included 83 patients (61% women), students of dental medicine, age 19-27 years. The experimental group (N = 42) was exposed to television commercials with a smile, and a control group (n = 41) to neutral television commercials. A month before exposure to these visual stimuli, and immediately after the exposure respondents answered the questionnaire which assessed the perception of their own orofacial aesthetics and its psychosocial effects Psychosocial impact of dental aesthetics, Orofacial aesthetic scale and Oral health impact profile. Personality dimensions were estimated using the Self-esteem scale,Big Five Inventory and Multidimensional perfectionism scale. Subjects' disruption of aesthetic smile was clinically assessed by the Index of orthodontic treatment need and the Index of complexity, outcome and need . The statistical analysis used the t-test for dependent and independent samples, Pearson correlation and hierarchical multiple linear regression analysis. For the second time, respondents were more satisfied with their appearance and reported fewer and lesser psychosocial effects regardless of the type of visual stimuli. Regression indicates that the types of visual stimuli is significant predictor only of the changes of the psychological impact of dental aesthetics. In people with higher benefits, watching commercials with a smile will reduce less the psychological impact (p = 0.009). Age, sex, clinical condition, preexperimental satisfaction of teeth appearance and other personality traits do not affect this relationship. The content of advertisements to a lesser extent, changes the perception of orofacial aesthetic.
