Background: Smile, a personís ability to express a range of emotions with the structure and movement of the teeth and lips, can often determine how well a person can function in society. Hence; the present study was taken for assessing the Perception of Acceptable Range of Smiles by Specialists, General Dentists and Lay Persons. Materials & methods: A total of 120 subjects were enrolled. Inclusion criteria included: Two photographs of each individual were clicked; one of the smile and another of the smile in conjunction with the frontal view of face. Impression was taken and casts were made. Three study groups were made as follows: Group A: Five Evaluators with post graduate degrees in the field of conservative dentistry, prosthodontics, and orthodontics or aesthetic dentistry, Group B: Five Evaluators were general dentists, and Group C: Five Evaluators were lay persons. All the photographs of smiles were distributed randomly among the evaluators of different study groups. Results: Significant results were obtained while assessing the individual smile analysis in between different study groups. In the present study, mean percentage of smiles in conjugation with face among subjects of group A, Group B and Group C was 54.23, 63.85 and 72.49 respectively. Mean width: height ratio was 0.693. Mean RED proportion and lateral incisor position was 73.12% and 0.936 mm respectively. Conclusion: Analysis of the smile should be done in addition with the face as it is impossible to dissociate the smile from the individualís other facial components. Key words: Smile, Acceptable, Perception.
