Abstract

Background:  Evaluation of different smile types in males and females of south Rajasthan population on posed smile by clinical measurements and facial photographic methods on basis of upper incisor exposure parameter. Materials and Method: Samples were obtained from 224 participants from south rajasthan, kota analyzed. Three Facial photographs (at rest, at posed smile and with cheek retractor) of the subjects were taken. Two linear measurements upper incisor exposure on smile (UIES), upper incisor crown length (actual) (UICL), were measured with vernier caliper in clinical study and on photo paper on photographic study. Result: Clinically, the Upper incisor crown length, upper incisor exposure during a smile is greater than what in visible photographically (p<0.05). Upper incisor exposure on smile is higher in female in respect to male.  While Upper incisor crown length is higher in male study in respect to female. Upper incisor exposure on smile is higher in female in respect to male.  Conclusion: Males have higher tendency to increase crown length while exposure upon smile is very less compared to females’ incisors. On a posed smile there is an average to high smile in females (more than 100%), while males have average to low smiles(less than 75%).
