ABSTRACT According to the available literature its value ranges from 0.2 -2.5% and is more common in primary dentition. 5-11 This case report presents a rare case of bilateral fusion of permanent lateral incisor and canine. The purpose of this article is to highlight the rarity of the condition and to evaluate the presence of any associated pathology. Case report A 12 year-old girl reported to the Department of Orthodontics and Pediatric Dentistry with the complaint of having large teeth within her lower jaw. Her medical history was irrelevant with her condition. Intraoral examination revealed bilateral presence of unusually large teeth in the lower right and left lateral incisor and canine region. The two sites were strongly suggestive of conjoined permanent lateral incisors and canine teeth [Figure 1]. Deep labio-lingual groove was associated with the enlarged teeth. Radiographic evaluation of the side revealed fused 32, 33, 42 and 43 and two distinct roots and single pulp chamber and root canal were evident. [Figure 2]. Abstract Fusion is described as the union of two or more tooth buds. It is characterized by a reduced number of teeth , when fused tooth is counted as one . The prevalence of fused teeth in primary dentition is below 1% and even more less in permanent dentition. The occurrence of fusion in primary dentition may be followed by dental anomalies in permanent dentition. This case report presents a case of bilateral fusion of lateral incisor and canine in primary dentition which was followed by similar fusion in permanent dentition. The aim of this report is to highlight the rarity of such condition by virtue of the number of such cases reported in literature and to evaluate their pulpal morphologies to understand the type of fusion and presence of any other associated pathologies.
