Pyramidal molar roots in primary and permanent dentition along with non syndromic oligodontia in a 11 year old boy.

Primary and permanent molars are usually multi rooted. At times we can encounter cases with a single root, called pyramidal root. Oligodontia is defined as the developmental absence of six teeth or more, excluding third molars. It can be isolated (Oligodontia-I) or as a part of a syndrome (Oligodontia-S) such as in ectodermal dysplasia. The present report describes a case of single-rooted primary and permanent molars associated with oligodontia in an 11 year old boy with no apparent systemic complications.
