Abstract:
Geminated teeth occur more frequently in the deciduous dentition than in the permanent dentition, with prevalence figures of 0.6% and 0.1%, respectively. Bilateral presentation is rare. A survey of the literature showed that the prevalence estimates for bilateral double teeth range from 0.01% to 0.04% in the deciduous dentition, and 0.05% in the permanent dentition. In this article, we report a rare case of bilateral fusion of the maxillary permanent incisors, discuss possible histogenetic mechanisms related to this anomaly, and explain the treatment management.
