title: Hemisection of a fused tooth.
abstract: Fusion is a developmental anomaly which occurs due to a union of 1 or more adjacent teeth during morphodifferentiation of the dental germs. The present case report presents the hemisection of a maxillary central incisor fused with a supernumerary tooth. A 10-year-old boy was referred to clinic with the chief complaint of the presence of a large anterior tooth. Intraoral and radiographic investigations indicated fusion between the left central incisor and a supernumerary tooth. The fused tooth was separated with a diamond bur, and the supernumerary tooth was extracted. The left central incisor was restored with composite resin and the diastema between the maxillary central incisors was closed with orthodontic treatment. The left central incisor was still healthy after a follow-up examination period of 24 months. An ideal overjet and overbite relation was achieved at the end of the orthodontic treatment. Hemisection can be considered as an appropriate treatment alternative for a permanent tooth fused with a supernumerary tooth.
