Endodontic Management of Dens Evaginatus of Maxillary Central Incisors: A Rare Case Report

Abstract

Dens evaginatus is a disturbance in tooth development that produces a tubercle of hard tissue on the surface of the tooth. While prophylactic pulp capping is recommended for vital teeth, teeth with necrotic pulps require endodontic therapy or extraction. This rare case of a 24-yr-old Indian male with affected maxillary central incisors demonstrates the clinical consequences of dens evaginatus.

Five root canals in peg lateral incisor with dens invaginatus: A case report with new nomenclature for the five canals

“…[14] Cases of bilateral occurrence[151617] and rare cases are reported in molars,[18] premolars,[19] and maxillary central incisors. [20] An Indian study reported a prevalence of 0.5% of surveyed teeth;[21] however, according to a Chinese study, DI was found in 517 permanent teeth from 67 Chinese individuals, which account for 5% of DI. These authors believe that the prevalence of DI may be related to ethnic origin.…”

Multiple Dens Evaginatus of Premolars and Molars in Chinese Dentition: A Case Report and Literature Review

“…It may be subject to pulpal exposure if the cusp is removed or fractured by occlusal movement. Some researchers point out that the talon cusp should be differentiated from DE according to the location, incidence, and clinical appearance of the abnormality (Vasudev and Goel, 2005). Other scholars suggest the talon cusp and DE are the same type of anomaly (Levitan and Himel, 2006 (Hill and Bellis, 1984).…”

Conventional Treatment of Maxillary Incisor Type III Dens Invaginatus with Periapical Lesion: A Case Report

“…Therefore, in the event that a tooth is affected, its homologous counterpart will need to be investigated. Rare cases are reported for molars [16], premolars [15], and maxillary central incisors [17]. The cause for the appearance of dens invaginatus is unclear, but some evidence suggests familial and hereditary components [18].…”
