Dens Evaginatus involving multiple primary teeth: A rare case report

Abstract

This case report describes the anomalous development of Primary maxillary central incisor and mandibular first molars in a two-year-old Chinese boy. The primary maxillary central incisor radiographically demonstrated anomalous development characteristic of dens evaginatus. Similar findings were evident on Primary right and left mandibular first molars. Dens evaginatus is a condition that most commonly exhibited by protrusion of a tubercle from occlusal surfaces of posterior teeth, and lingual surfaces of anterior teeth. Although often observed, these anomalous teeth present some challenges to the dental practitioner. Morphologically anomalous cusp-like protrusions are susceptible to pulp exposure from wear or fracture because of malocclusion, leading to pulpal complications soon after eruption. This article illustrates a case in which a child demonstrated extra cusp in relation to primary maxillary central 
incisor and mandibular right and left first molars suggestive of dens envaginatus. The many challenges associated with the presence of such teeth are discussed
