Nonsurgical endodontic treatment of type III dens invaginatus in maxillary canine: an 18-month follow-up

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. This report presents regenerative endodontic treatment of a necrotic immature tooth with Oehler’s type III dens invaginatus of a nine-year-old female patient. A diagnosis of dens invaginatus (Oehler’s type III) and a large periapical lesion was established with the aid of cone-beam computed tomography (CBCT). In the presented case contrary to the classic revascularization protocol, mechanical instrumentation was performed which apparently did not interfere with the regeneration process. After mechanical instrumentation of the invaginated canal by manual K-files, the invaginated canal space was disinfected by triple antibiotic paste followed by blood clot induction from the periapical tissues and the placement of mineral trioxide aggregate. At one-year follow-up, the tooth remained clinically asymptomatic. Radiographic examination revealed complete healing of the periapical lesion. At the 20-month follow-up, the radiographic examination also showed that the open apex was closed and the walls of the root canal were thickened.

Dens Invaginatus

Endodontic treatment of two maxillaryincisors with dens invaginatus is reported. Invaginated teeth present technical difficulties with respect to their management because of complicated canal morphology. This case was treated by conventional root canal treatment. The signs and symptoms ceased after the treatment. At follow up examination after 18 and 20 month the teeth were asymptomatic and radiographically showed sound periodontal and periapical tissue.
