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.

Management of three fused primary teeth.

Fusion is a dental anomaly in which two dental germs have developed separately and then become united. It is often confused with germination, unless until carefully evaluated clinically and radiographically. This paper describes a case of a six year old boy who presented with pain and swelling in right lower back tooth region. Intra oral examination revealed three fused primary teeth, which were confirmed radiographically. Radiographs also revealed missing permanent tooth buds associated with them. Since all the fused teeth were pulpally involved they were managed by pulpectomy. The incidence, prevalence, complications and treatment modalities are also discussed in this case report.
