Sambit Subhas

Background and Objectives: The selection of artificial teeth for edentulous patient is a primary concern in denture aesthetics, especially maxillary central incisors because they are the most prominent teeth in the arch. This study evaluates the correlation between maxillary central incisor form and face form in Indian population. Method: 200 dental student subjects of Indian origin with 79 males and 121 females in age group of 18-28 years studying in Awadh Dental College and Hospital were randomly selected for the study. A standardized photographic procedure was used to obtain images of the face and the maxillary central incisors. The outline form of the face and the right maxillary central incisor tooth were determined by a standardized method. The means were considered as evaluated by 5 postgraduate students with 2 years of experience and results were tabulated. The statistical analysis was done by Chi-square test for the association and Z-test for equality of proportions. Results: Out of total 400 subjects, 3 different face forms: square, ovoid and tapering face forms and 4 different tooth forms: square, ovoid, tapering and combination tooth forms were evaluated. The predominant tooth form was square and combination tooth form in both males and females and the predominant face form was square in males and ovoid in females. Interpretation and Conclusion: Within the population evaluated, greater correlation exhibited between tooth form and face form by visual method than between tooth form and face form by Williamís method. Key words: Tooth form; Face from; Maxillary central incisor.
