Introduction:

Gemination is the division of a dental follicle that results in a tooth with two crowns, where the number of teeth in the arch does not vary. It constitutes an anomaly that is little diagnosed due to its presentation and therefore little treated, which requires an adequate study.

Objective:

To present an infrequent clinical case of dental gemination of the permanent upper left lateral incisor.

Clinical case:

20-year-old patient with 30 weeks of gestational status treated for periodic review by appointment of her dentist. The intraoral examination revealed: the permanent upper left lateral incisor (tooth 22) with two crowns, one of which had lost the gingival wall and the other had second degree dental caries on the mesial side. Periapical radiography performed 1 year earlier showed tooth 22 with a partially divided pulp chamber and a broad, bifid, well-defined crown. Dental gemination of the permanent maxillary left lateral incisor was diagnosed. The geminated tooth was extracted, and the patient was referred to a dental prosthesis for rehabilitation.

Conclusions:

Dental gemination of the permanent upper left lateral incisor in a pregnant patient, constitutes an anomaly of the shape of the teeth that is infrequent in consultations.
