Diagnosis and Management for a Supplemental Mandibular Incisor - A Case Report
下顎前牙區之副型多生牙的診斷及處置－病例報告
摘要
Occurrence of supernumerary teeth in the mandibular anterior region is very rare, accounting for only 2% of supernumerary cases. They are commonly classified as supplemental or rudimentary according to the morphology. Supplemental type refers to supernumerary teeth of normal shape and size, also termed incisor-like, which makes a diagnosis quite challenging. It is necessary to assess the proper sequence and symmetric pattern of permanent tooth eruption patterns at the time of the clinical examination. Asymmetric eruption pattern and over-retention of primary teeth at a specific region can be a sign of supernumerary teeth. Early diagnosis and management of supernumerary teeth is imperative to prevent unfavorable consequences, such as delayed eruption of permanent teeth, dilacerations or delayed root development, displacement of tooth germs, root resorption of adjacent teeth, dental crowding, and formation of odontogenic cysts or tumors. In this report, we presented a rare case of five mandibular incisors and discussed its diagnosis and management.
