An unusual triplication of primary teeth - A rare case report

Odontogenic anomalies can occur as a result of conjoining or twinning defects. This article reports the case of fusion in a 10-year-old boy in relation to the primary maxillary right incisors. Clinicoradiographic examination revealed the presence of triple teeth, ie, fusion between the maxillary right incisors along with a supernumerary tooth on the labial surface. The offending triple tooth was extracted under local anesthesia. The extracted tooth was sectioned using a hard tissue microtome at three levels-the coronal, middle root, and apical levels, respectively-and these sections were visualized under a stereomicroscope. Based on the histologic findings, a final diagnosis of fusion was confirmed. A brief review of the literature on triple teeth is also presented.
