Retention of upper incisors. Causes of retention and comparison of treatment possibilities

Abstract

The aim of study is to evaluate the presence of an extra supernumerary tooth in the central position of the upper or lower jaw which is called mesiodens. The prevalence in the general population of 0.15-1.9 %, the shape is conical and mesiodens is smaller than the central or lateral incisor.

Several hypotheses have been suggested for the formation of supernumerary teeth. Early diagnosis and treatment are needed
