“…The etiology of dens invaginatus is controversial, with theories ranging from aggressive proliferation of the inner enamel epithelium or retardation of groups of cells, to pressure on the tooth germ, infection, or trauma 1-5…”

It has been a challenge to establish the accurate diagnosis of developmental tooth anomalies based on periapical radiographs. Recently, three-dimensional imaging by cone beam computed tomography has provided useful information to investigate the complex anatomy of and establish the proper management for tooth anomalies. The most severe variant of dens invaginatus, known as dilated odontome, is a rare occurrence, and the cone beam computed tomographic findings of this anomaly have never been reported for an erupted permanent maxillary central incisor. The occurrence of talon cusp occurring along with dens invaginatus is also unusual. The aim of this report was to show the importance of cone beam computed tomography in contributing to the accurate diagnosis and evaluation of the complex anatomy of this rare anomaly.

“…A dilated odontoma is an extremely rare developmental anomaly that is represented as a dilatation of the crown and root as a consequence of a deep, enamel-lined invagination and is considered a severe variation of dens invaginatus [ 1 ]. Proposed theories for origin of dilated odontoma comprise focal growth retardation theory, restricted external pressure, and focal growth stimulation in selected parts of the tooth bud [ 2 ]. Dilated odontoma originates during the morphodifferentiation stage of tooth bud formation, but its precise aetiology and genesis are unidentified [ 2 ].…”

A dilated odontoma is an extremely rare developmental anomaly represented as a dilatation of the crown and root as a consequence of a deep, enamel-lined invagination and is considered a severe variant of dens invaginatus. An oval shape of the tooth lacking morphological characteristics of a crown or root implies that the invagination happened in the initial stages of morphodifferentiation. Spontaneous eruption of an odontoma is a rare occurrence and the occurrence of a dilated odontoma in a supernumerary tooth is even rarer with only a few case reports documented in the English literature. We present an extremely rare case of erupted dilated odontoma occurring in the supernumerary tooth in anterior maxillary region in an 18-year-old male, which, to the best of our knowledge, is the first ever case reported in English literature.
