Morphology of tooth varies among individual patient.It is an important consideration in evaluating occlusion and esthetics.The incisor teeth have different shapes namely triangular, rhomboid, square. Shape of incisors also plays a major role in esthetics.It is important for proper finishing of the dentition at the end of orthodontic treatment.The aim of this study is to determine the incisal tooth morphology of the patients visiting the orthodontic treatment.This study was conducted as a hospital based study localised to the Chennai population. Data was systematically reviewed and retrieved from the archived database.The data was grouped into two groups. Group 1 patients had class I malocclusion and Group 2 Patients had class II and Class III malocclusion. Shape of incisors were evaluated for all the patients of both the groups. On analysing the results, among the patients of Group1, 84.21% of the males and 91.30% of the females had triangular incisors.Among the patients of Group 2, 70.59% of males and 68.42% of the females had triangular incisors, irrespective of the type of malocclusion. On chi square analysis, the value was found to be 0.356 ( p value > 0.005), does not have significant association.It was concluded that the most predominant shape of the incisors was found to be triangular.
