Impaction of mandibular molar by supernumerary tooth: case report.

The occurrence of supernumerary teeth in the lower molar region is rare. A prevalence of less than 2% of cases occurring in this region has been estimated. The aim of this study was to present a clinical case of a 7-year-old female patient who had a supernumerary tubercular tooth between the distal root of the primary mandibular left second molar and the impacted permanent mandibular left first molar. Treatment consisted of surgical removal of the supernumerary tooth and case follow-up until the permanent molar's eruption, which occurred in 13 months. This study emphasizes the importance of: early diagnosis, appropriate intervention, and recommended preservation. Thus, it is possible to prevent or reduce complications, simplifying the case outcome.
