Aim: This case report aims to present triple tooth synodontia of primary teeth and its management. Background: Synodontia refers to the fusion of teeth and is a morphological developmental dental aberration. This anomaly is also acknowledged with different terminologies like fusion, germination, and concrescence. Synodontia with two teeth is not uncommon however it is found sporadic in primary dentition. This type of anomaly can include two or more teeth; if the number is two, it is called as double tooth and if three, is called as triple tooth or triplication defect or triploid tooth. Case Description: In this article, we report an unusual case of triplication of primary teeth occurring unilaterally between the upper deciduous right central, lateral incisor and supernumerary tooth. The triple tooth was extracted under local anesthesia and was sectioned at three levels that are coronal, middle, and cervical one-third, and analyzed by Cone-beam Computerized Tomography (CBCT) respectively. The coronal segment revealed three individual pulp chambers, middle third and apical third revealed one single unified pulp chamber. Conclusion: Triple tooth in a triangular configuration with mixture of incomplete fusion at the coronal portion and cervical third and complete fusion at middle and apical third of root is an elusive anomaly. Clinical significance: This aberrant fusion of two deciduous incisors with supernumerary tooth had been documented as rare anomaly, so its early diagnosis and management protocol is imperative to comprehend.
