Abstract

Supernumerary tooth describes an excess of tooth number, which are found in primary dentition with 0.3-0.8%, permanent dentition with 1.0-3.5% prevalence. Their frequency is about 2:1 (male vs female) and 9:1 (maxilla vs mandible). However, occurrence is very rare in the incisor region of the mandible. We need a early diagnosis and appropriate treatment plan because of possibility of diastema, eruption failure, displacement, rotation of the associated permanent teeth, root resorption, dentigerous cyst with presence of the supernumerary teeth. This is a case report about two impacted supernumerary teeth found in madibular anterior region of 6 years old girl. One was extracted and another was retained because of fusion with permanent central incisor on the labial surface.
