Abstract

Partial Dental Agenesis has been shown related to decreased mesiodistal tooth size. The sexual difference in permanent tooth size of 104 normal individuals with congenital absence of one or more secondary teeth has been studied. Males are observed to have more mesiodistal size reduction than females. In only two of 14 tooth types examined was a statistical sex difference in mesiodistal size shown. It is of interest that each of these was in the canine field area.

A sex difference was slightly more apparent when studying the buccolingual dimension; however, several difficulties were encountered in obtaining measurements in this diameter.
