Abstract
Facial esthetics has been the most important objective of orthodontic treatment planning. Smile characteristics are determined
by static and dynamic relationships between hard and soft tissue components of face. The objective of the present study was to
evaluate the balanced smile using different hard and soft tissue parameters.A total of 50 participants equally divided into two goups i.e
males and females, ranging in age from 18–25 years with Angle’s Class 1 molar relation were selected. Photographic records of smile
and rest position were measured and analyzed at rest and during smile, to assess upper lip length, maxillary incisal display, upper
vermillion length, intercommissural width and smile arc. Results obtained from both the groups were subjected to stastical analysis
and correlations between smile variables were investigated. Most of the measured variables showed statistically significant sexual dimorphism. Statistically significant results were seen in relaxed upper lip length, relaxed central incisor display, relaxed vermillion length, smiling upper lip length and smiling vermillion length. Resting inter commissural width, smiling central incisor display and smiling inter commissural width were found to be statistically non-significant. Upper lip length and vermillion length in smiling and resting conditions had same pattern. Increased incisal display was more evident in subjects with short upper lip. Parallel smile arc and flat smile arc distribution was more common in females subjects whereas reverse smile arc was seen in male patients only.
