Dens in dente is characterised as a developmental anomaly resulting from invagination of the enamel organ into the dental papilla. It is a rare malformation of teeth, showing a wide spectrum of morphological variations such as gemination, microdontia, taurodontism, dentinogenesis imperfecta, supernumerary tooth and hyperplasias, resulting frequently in early pulp necrosis. Maxillary lateral incisors are the commonest teeth to be affected by dental malformations—supernumerary tooth, talon cusp, congenitally missing tooth and dens in dente. We describe the management of a case of dens in dente in a maxillary lateral incisor with a periradicular lesion.
