Unique case of a geminated supernumerary tooth with trifid crown

Abstract

Gemination, a relatively uncommon dental anomaly, is characterized by its peculiar representation as a tooth with a bifid crown and a common root and root canal. It usually occurs in primary dentition. To come across gemination in a supernumerary tooth is a rare phenomenon. The purpose of this paper is to present a unique case of hyperdontia wherein gemination in an impacted supernumerary tooth resulted in a trifid crown unlike the usual bifid crown. The role of conventional radiographs as well as computed tomography, to accurately determine the morphology and spatial location, and to arrive at a diagnosis, is also emphasized in this paper.

“…Only two cases were evaluated with using tomography. 16,17 Pain, swelling, and food lodgement were the chief complaint when geminated premolar teeth are symptomatic. Table 1.…”

Multiple Geminated Supernumerary Premolars: A Rare Case Report

“…The possibility of fused supernumerary premolars in the present case report was unlikely as there was an obvious bifid crown along with a single root in all three observed supernumerary premolars. The occurrence of gemination in a supernumerary tooth is very rare as only three cases of gemination in supernumerary premolars have been documented ( Table 1 ) [ 4 , 7 , 8 ]. The present case is extremely rare and interesting as there was gemination of multiple supernumerary premolars in a nonsyndromic patient.…”

“…Gemination is a developmental disturbance of the shape of teeth and is usually recognized as a partial cleavage of a single tooth germ resulting in one root and one pulp space with two partially or totally separated crowns [ 4 ]. Though it occurs in both dentitions, it has a higher prevalence in deciduous teeth, with a higher frequency in anterior maxillary region.…”

Diagnosis and management of mandibular hyperdontia in a non-syndromic patient: A rare case report

“…The term supplemental tooth is used when the teeth are extra but have the shape and size of normal teeth. [4] Several treatment modalities have been described in the literature for the management of geminated teeth. They are generally asymptomatic but are unesthetic.…”

“…[4] In fusion, the crowns are united by enamel and/or dentine, but there are two roots or two root canals in a single root. In contrast, in gemination, the structure most often presents two crowns, either totally or partially separated, with a single root and one root canal.…”
