Clinical Course and Treatment of a Triplication Defect: A Case Report

Fusion is an anomaly manifested in both deciduous and permanent dentitions. Fusion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. Triple tooth refers to the union of three separate tooth entities. It can occur by fusion, germination, concrescence or a combination of both fusion and germination. Triplication is rarely encountered in the deciduous dentition. The case presented herein describes triplication of deciduous incisors and a supernumerary tooth. The diagnosis was confirmed with the help of radiographs, computed tomography (CT) imaging and histological examination. Retention of the triple tooth had led to crossbite. Extraction was performed for the triple tooth and crossbite was corrected using a composite inclined plane.
