Proper diagnosis of tooth size for each patient is critical in treatment planning for aesthetic restorative dentistry. The goal of this study was to determine the clinically relevant range and mean distribution frequency of individual tooth width of the maxillary anterior dentition within a given population of patients. Mean values for restoration of tooth size were not interchangeable for the different group size of patients or respective tooth groups. The results of this study suggest that there exists a range value of maxillary anterior tooth width for both males and females. Gender differences are a critical factor in restoring an aesthetically pleasing smile.

Learning Objectives:

This article will discuss the clinical significance of tooth biometry and distribution frequency, in which size for tooth restoration may vary among patients of different age, race, or sex. Upon reading this article, the reader should:

• Become more familiar with the range of individual tooth width of the maxillary anterior dentition and their mean distribution frequencies.
• Understand that gender differences may exist affecting the width of maxillary anterior teeth.
