Abstract

Dens in dente is a rare structural abnormality arising during tooth development. It is also called dens invaginatus or dilated odontoma, which develops following inward folding (invagination) of the enamel organ into the dental papilla. Maxillary lateral incisors are the most frequently affected teeth. Dens in dente often leads to pulp necrosis and development of a periapical lesion. Also, impacted teeth are one of the reasons for development of odontogenic cysts and tumors. A dentigerous cyst, classified as an odontogenic cyst, develops around the crown of an unerupted tooth. These cysts most frequently involve mandibular third molars; they are also commonly associated with maxillary canines and mandibular second premolars. This report describes a dens in dente in a maxillary lateral incisor, and impacted maxillary canine teeth with extended periodontitis and their management by a combination of root canal and surgical treatments.
