Supplemental Permanent Mandibular Incisor- A Rare Case Report

Anomaly in the number of teeth may manifest as a supernumerary tooth. Occurrence of a supernumerary tooth in the mandibular incisor region is uncommon. This report presents a rare case of five mandibular permanent incisors in a nine year old non-syndrome healthy male child. Clinical and radiographic examination revealed the presence of a supplemental (type of supernumerary) permanent incisor in the mandibular arch. Recognition of tooth anomalies is important during routine examination. Detection of supernumerary teeth is best achieved by thorough clinical and radiographic evaluation.  Dentists should be aware of this condition when unusual crowding and displacement is seen in the mandibular incisor region. Early diagnosis may provide a better opportunity for optimal treatment outcome.
