Description

ABSTRACT

Objective: To determine predominant face form and tooth form in males and females among Indian population.

Material and methods: A standardized digital photograph of full face and the maxillary central incisors of 200 dental students with 79 males and 121 females in age group between 18 and 28 years were included in the study. The image prints of traced outline form of the face and the right maxillary central incisor tooth were obtained separately to classify the face form and the tooth form according to William’s method. The images prints to classify the face form and the maxillary central incisor tooth form were done by 5 prosthodontists. The means were considered, respective percentages were statistically analyzed by Chi-square test and the results tabulated.

Results: The maxillary central incisor tooth showed considerable asymmetry where as the face were basically symmetric The predominant tooth form is combination tooth form in both males and females and the predominant face form is square in males and ovoid in females.

Conclusion: The predominant face form and tooth form obtained is useful in selection of anterior teeth for edentulous patients among Indian population.

Keywords: Tooth form; Face form; Typal form; Nontypal form; Combination form; William’s method.
