PDF: Dental Gemination in a Permanent Mandibular Central Incisor: an Uncommon Dental Anomaly

Gemination is an anomaly in size, shape, and structure of the teeth. The primary dentition is more frequently affected, but gemination may occur in permanent dentitions, usually in the maxillary-incisal region.

Dental-Gemination


In geminated teeth, incomplete development of two teeth from a single bud results in a larger tooth crown with a single root and canal. In this study, a gemination case in a male patient, 13-year-old, with an ancestry of Aymara, who visited a private clinic in Antofagasta, Chile, for a routine check is presented.

On intra-oral clinical examination of the coronary anatomy, the tooth 4.1 was observed with a large crown, bifurcated in the center of incisal zone. In addition, a groove extending from the bifurcation to the cementoenamel junction was noted.

Radiographic examination revealed the presence of a single root canal and a single root. The pulp cavity was separated in two cavities, in accordance with the division caused by the observed bifurcation. 

This report describes a unique case of dental gemination of mandibular permanent central incisor in a subject with Aymara ancestry and discusses the differential diagnosis and possible future treatment options anticipated for this particular case.
