A radicular variant of dens invaginatus ( DI ) is a rare form of dens invaginatus which develops in the root of the tooth after the crown development is completed. This report involves successful management of a case with guided tissue regeneration and describes the cone beam computed tomography ( CBCT ) characteristics of true radicular DI . A 20‐year‐old woman reported with recurrent swelling and pus discharge associated with her maxillary left central incisor (#21). Cone beam computed tomography ( CBCT ) of the region revealed #21 had an invagination in the mesial aspect of the coronal third of the root with a para radicular low‐density region perforating both the cortices. A diagnosis of true radicular variant of DI was made by exclusion. The case was managed with Biodentine ® , platelet‐rich fibrin and freeze‐dried demineralised bone graft. A 2‐year review showed that the tooth was functional with normal periodontal parameters and normal response to electric pulp sensibility test.
