Abstract

Congenital missing of one or more teeth, excluding the third molars is relatively common, but anodontia or oligodontia is rare and may be associated with ectodermal dysplasia. In this study, it was found that among (379) prosthodontic patients, one patient had anodontia representing (0.26 %) of the cases and need complete denture for esthetic and functional demands, and two patients had oligodontia representing (0.52 %). These percentages were higher than other studies in the world, may be due to environmental and / or congenital causes.
