Prevalence of supernumerary teeth in deciduous and mixed dentition.

ABSTRACT

Supernumerary teeth are the extra teeth which may have either erupted or unerupted in addition to normal dentition and are seen both in deciduous as well as permanent dentition. The incidence of supernumerary teeth shows more frequent occurrence in permanent dentition than deciduous dentition, affecting both the sexes. The etiology of supernumerary teeth is still unknown and not well understood, but thought to be the result from disturbance during the initiation and proliferation stages of tooth development. In the present study an attempt has been made to asses, its prevalence in deciduous and mixed dentition phase.
