Type III dens invaginatus in a mandibular incisor: a case report of a conventional endodontic treatment.
This article presents one of the few reported cases of endodontic treatment of class III dens invaginatus involving mandibular incisor. Due to invagination extending through the root, supposedly communicating laterally with the periodontal ligament space through the pseudoforamen, this case was classified as Oehlers type IIIA. The periradicular radiolucency was evident around the root apex with 5.0 × 3.0 mm diameter. The conventional chemical and mechanical preparation with hand files and 2.5% sodium hypochlorite combined with intracanal dressing with calcium hydroxide for 6 weeks was able to promote the regression of lesion noted at 1-year follow-up. This case reinforces the precept that knowledge about the biologic aspects of endodontics combined with adherence to technical standards are able to resolve complex cases without the need of additional resources.
