Sažetak
Objective - The aim of this study was to determine the psychosocial influence of elements of smile esthetics. Materials and methods - The study was cross-sectional with convinient sample that included orthodontic patients, pupils, students and faculty staff. A total of 155 subjects (36% males) aged 12-39 (mean age 21, Interquartile range 19-23) were included. Occlusal characteristics were recorded by the Index of Complexity, Outcome and Need, and smiling frontal view photographs were obtained (photographed in natural head position with calibration device). Fourteen variables were measured using photogrammetric analysis in AudaxCeph software (Audax, Slovenia) : smile width, visibility of buccal corridors, maximum teeth exposure, total gingiva display, lip thickness, degree of occlusal cant and deviation from golden proportion of the teeth in maxillary intercanine sector. Psychometric instruments included validated Croatian version of the Psychosocial Impact of Dental Aesthetics Questionnaire and the Rosenberg Self-Esteem Scale. Multiple linear regression was used in statistical analyses. Results - Malocclusion severity is the most important predictor of psychosocial influence of smile esthetics and self-esteem, the unique contribution of which accounts for a total of 4-27% of variability. Female gender, less incisor exposure and decreased visibility of lateral incisor width than golden proportion standard are additional predictors of higher level of esthetic concern. Female gender is associated with higher psychological influence of dental esthetics while male gender and older age with self-esteem. Conclusion - Malocclusions have higher psychosocial impact than parametres of mini and microesthetics of smile related to visibility of buccal corridors, amount of teeth exposure, gingival display, lip thickness, presence of occlusal cant and deviation from golden proportion of the teeth. It appears that people are not as focused on details of their smile as they are on distinctive malposition of teeth.
