ROLE OF DYNAMIC SMILE ON OVERALL FACIAL ESTHETICS : A VIDEOGRAPHIC EVALUATION

Abstract

Introduction: Various studies have been done to analyze the posed smile with full facial features. But very scanty literature is present which establish the importance of dynamic smile in overall facial esthetics. Therefore this study was designed to capture smile in both static and dynamic form using photographic and videographic methods respectively; and assess the role of dynamic smile on overall facial esthetics. Method: The study was carried out on 166 subjects from the local population. Both static and dynamic smile were recorded. Three static parameters that are non-smiling full face, smiling full face, smiling focus on nose and mouth and two dynamic parameters that smiling full face, smiling focus on nose and mouth. The screening was done by the panel of 5 judges comprising of an Orthodontist, a Dentist, a Photographer, a Beautician and a Layperson using visual analog scale. Result: Among Males (Group I), score was highest with respect to (Group ID) “Dynamic smiling focus full face” followed by (Group IB) “Static smiling focus on full face” then (Group IA) “Static non smiling focus on full face” then (Group IC) “Static smiling Focus on nose and chin” (Group IE) “Dynamic smiling focus on nose and chin” respectively. Mean VAS scores of all the 5 parameters among Females (Group II), highest Mean scores was found with respect to (Group IID) “Dynamic smiling focus full face” followed by (Group IIA) “Static non smiling focus on full face” then (Group IIB) “Static smiling focus on full” face then (Group IIE) “Dynamic focus on nose and chin”) and lastly (Group IIC) “Static smiling Focus on nose and chin”. Conclusion: Dynamic smile plays a very important role in overall facial esthetics thus can be used as an important clinical tool, as it allows not only to capture the best frame of smile for smile analysis
