Fusion of maxillary central incisors with mesiodens

Journal of Oral and Maxillofacial Pathology, 2018
Fusion and gemination are developmental anomalies which are quite similar to each other but can be distinguished from each other if properly assessed. Fusion and gemination have been described as a result of developmental anomalies of dental tissues. The exact etiology is still unknown, but a genetic predisposition is suggested. This article highlights
