Concurrent occurrence of dens evaginatus and dens invaginatus in maxillary incisors: a case report and review

Abstract

Dens evaginatus (DE) and dens invaginatus (DI) are developmental anomalies that affect the shape of the teeth. Although they have been found singly and in association with other developmental anomalies in the same patient, it is uncommon to observe these two anomalies in the same tooth. There are only a few published cases of concurrent DI and DE in the same tooth. The patient in the case reported here was a 27-year-old man who exhibited a novel combination of DE and DI in permanent maxillary incisors. Early diagnosis of this anomaly is necessary. The clinician then can take particular care when performing prophylactic odontoplasty for the DE, keeping in mind that the associated DI presents an increased risk of early pulpal involvement. This article focuses on the management aspects of DE and DI.

Diagnosis and management of a maxillary lateral incisor exhibiting dens invaginatus and dens evaginatus

“…Agrawal et al ., Anthonappa et al ., Gehlot et al ., Kiswani and Marya et al . have subsequently recorded the presence of DE and DI in the same tooth . Hence, if one accepts this trend in recent literature, this case report adds to a scant pool of evidence.…”

Prevalencia de diente invaginado en niñas y niños atendidos en la Facultad de Odontología de la Universidad de Costa Rica

“…La incidencia del DI ha sido reportado en un rango de 0.04 % a 10 % (17), la prevalencia varía sustancialmente, dependiendo del tipo de clasificación (27 Comunmente el incisivo lateral superior permanente es el más afectado y en orden descendente le sigue el incisivo central permanente, incisivos mandibulares, premolares y caninos (7,11) y extremadamente raro en molares (30). La mayor parte de los casos son unilaterales, aunque los casos bilaterales ocurren en un 43% por lo que se recomienda examinar el diente homólogo (31).…”
