Abstract

This paper reports the case of a 3‐year‐old male patient with triple teeth in the right maxillary incisor region and double teeth in the left mandibular incisor region. He had pre‐existing medical conditions. The triple teeth were extracted and examined using micro‐computed tomography. A literature review was performed to discuss this abnormality.

Highlights

Dental abnormalities such as fusion or gemination have been described in both dentitions
Fused teeth correspond to the union of two or three normal tooth germs, or one or two normal tooth germs and one supernumerary tooth
This paper aimed to report a rare case of a young patient presenting large triple teeth in the right maxillary incisor region and double teeth in the left mandibular incisal region, which has not been reported in the literature before, and further discuss it by a comprehensive literature search on triple teeth

Summary

Introduction

Dental abnormalities such as fusion or gemination have been described in both dentitions. Depending on when it happens during tooth development, the fusion can be complete or incomplete; the pulp chamber and root canal may be joined or separated. When fusion occurs after crown completion, the teeth are united only by the cementum; this is called concrescence.[1,2] Gemination is the failure of attempted tooth-germ cleavage with incomplete formation of two teeth, usually with one pulp chamber, a single root, and a common pulp canal. Twinning represents complete formation of two nearly identical teeth, one normal and one supernumerary tooth, but fused as one, usually with a single root and a single pulp canal.[1,2] In the case of three tooth entities, the terms “triple tooth,”“triple teeth,” or
