FARINHA, Inês et al. Nonsurgical endodontic treatment of a mandibular canine presenting with dens invaginatus type IIIb: Case report. Rev Port Estomatol Med Dent Cir Maxilofac [online]. 2020, vol.61, n.4, pp.181-186.  Epub 30-Dez-2020. ISSN 1646-2890.  https://doi.org/10.24873/j.rpemd.2020.12.722.

Dens invaginatus consists of a malformation that occurs during the tooth development phase. More-severe cases may affect both the crown and the root. The endodontic treatment is more complex and challenging. The purpose of this article is to report the nonsurgical endodontic treatment of a mandibular canine diagnosed with an Oehler’s dens invaginatus type IIIb with an acute periapical abscess. The treatment consisted of treating the invagination while maintaining the vitality of the pulp tissue. A radiographic six-month follow-up confirmed the apical pathosis’s resolution, while the clinical evaluation confirmed the maintenance of a healthy pulp. The endodontic treatment can be successfully performed when an early and correct diagnosis is established. Cone-beam computerized tomography and magnification are extremely useful when approaching such cases.
