ALVES, Nilton; NASCIMENTO, Carlos Manuel de Oliveira  and  PATRIARCA, Juvenal João. Dental Gemination in the Inferior Canine in Both Dentition: Case Report. Int. J. Morphol. [online]. 2010, vol.28, n.3, pp.873-874. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022010000300033.

Geminate teeth are anomalies arising from the attempt of the division of a only one germ, characterized by invagination and resulting in incomplete formation of two teeth. In general, it presents two crowns, totally or partially separated, with one root and one root canal. Female patient, 8 years old, Asian descent (Chinese), attended a private clinic (Odemira Dental Clinic) in Odemira, Portugal, for a routine consult. At intraoral clinical examination differentiated coronary anatomy, of the tooth 83 was found , with the presence of a bifid crown in which there was a central groove that came from the cemento-enamel junction. The radiographic exam revealed the presence of only one wide root canal, and two separate pulp cavities, each one corresponding to a portion of the bifid crown. There was also, its permanent successor, with similar radiographic features In our case we could observe the alteration in the inferior canine of both dentition with a bifid crown and radiographically only one root as well as only one root canal with two pulp cavities.
