Cone beam CT and stereolithographic model in primary dentition

There are many recognized dental anomalies, among the least common being the “triple tooth”, with a prevalence of 0.02% in the primary dentition. However, such malformation can more easily lead not only to carious pathology, due to dental dysmorphisms, and pulpal lesions, but also to rhizalysis and agenesis of the permanent elements, causing eruption alterations and malocclusions. Therefore, techniques such as CBCT and 3D anatomical replicas have been proposed to be able to study complex clinical situations such as the triple tooth in its entirety, in order to analyze anatomical structures and identify the best treatment plan. In this paper we propose a clinical case of a triple tooth in a 6-year-old child in the left mandible with fusion of incisor with a supernumerary tooth associated with the lateral incisor fusion.
