A Fused Supernumerary Tooth Associated with Dilated Odontoma

Supernumerary teeth are denoted as those in addition to the normal number of permanent or deciduous dentitions.They may occur anywhere in the dental arch and lead to many aesthetic and functional problems.Dilated odontoma is the most severe form of dens invaginatus.Dens invaginatus is a developmental malformation that occurs due to infolding the enamel into dentine.This invagination can cause pulp necrosis and periapical lesion.In this rare case there is a fused supernumerary tooth associated with dilated odontoma in the anterior mandible, which is detected accurately by clinical features and radiographs, particularly Cone-Beam Computed Tomography (CBCT).
