“…The soft tissue contents of the invagination, though predominantly connective tissue, may also contain osseous deposits. Apart from this case, the only other CBCT based description of a true radicular DI was an incidental finding reported by Neves, where no treatment was provided . Both in this case and the one reported by Neves did not have any enamel lining in the invagination, and the soft tissue within the invagination was devoid of calcifications.…”

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.

“…In this case, the CT has contributed to diagnosing radicular dens invaginatus, as reported by other authors. 9,12,14 However, confirmation of the diagnosis of type IIIb dens invaginatus could be completed only after histopathological analysis, which revealed the presence of an irregular central cavity that corresponded to the pulp cavity, containing remnants of pulp tissue, and at the periphery we observed a narrow channel with faulty walls circumventing the root dentin.…”

Dens invaginatus is a dental anomaly caused by an invagination of enamel that affects in most of the cases the crown of the tooth. The treatment depends on the degree of invagination and morphological involvement. This report describes a dental anomaly affecting the permanent lower lateral incisor of a 13-yearold patient, which resulted in swelling, pain, and dental impaction. The initial radiographic examination suggested a gemination, a fusion with a supernumerary tooth or a dens invaginatus extending to the root. For more accurate diagnosis and treatment plan of this anomaly, computed tomography scan was performed, which revealed the presence of enamel in the root. Due to pain and the impossibility of performing an orthodontic traction, the treatment of choice in this case was dental extraction. The final diagnosis was confirmed by histopathological examination and revealed the rare occurrence of a radicular dens invaginatus.

“…For DI diagnosis, although orthopantomography and periapical radiographs may be sufficient, they may be insufficient for some cases requiring detailed examination. Neves et al (27) specified that conventional radiographs were insufficient in the case report in which they examined radicular DI with CBCT.…”

Wilson's disease (WD) is a rare autosomal recessive genetic disease that affects copper metabolism. Anomalies can be seen in the dento-maxillofacial structures of WD patients. Dens invaginatus (DI) is an uncommon tooth anomaly, and its incidence in decidious and permanent molars is even lower. This case report primarily explored the multiple DI of a patient with WD. A 9-year-old boy was admitted to our clinic with complaints of pain and swelling in the right lower molar area. It was learnt that the patient was diagnosed with WD after he was born. Fistula, submandibular lymphadenopathy and diffuse swelling were detected. Using cone-beam computed tomography (CBCT), multiple DIs were observed in bilateral bimaxillary four first molars and deciduous molars. When the patient's systemic condition was considered, extraction was planned under oral antibiotic therapy and was performed. During the 6-month follow-up, uneventful healing was observed.
