Conservative Treatment of Fused Teeth in Permanent Dentition

Dental fusion is a rare developmental anomaly which is included in the anomalies of tooth size. Fusion can occur at the level of enamel or enamel and dentin which results in the formation of a single tooth with enlarged clinical crown. Etiology of fusion is not fully clarified. According to the available literature, the incidence of fusion ranges from 0.2 to 2.5% and is more common in decidious dentition. In the case report presented, fused incisors were treated endodontically and reconstructed by composite materials.
