RESUMO

INTRODUCTION: The morphogenic complexities of dens invaginatus (DI) Oehlers type 3 in maxillary canines offer significant endodontic challenges. METHODS: A case report is provided of a 14-year-old female patient who presented with an anomalous-looking permanent maxillary canine associated with a sinus tract. Pulp testing revealed a normal response on the distal aspect of the tooth, whereas the mesial segment tested nonresponsive. A radiolucent lesion was seen on the mesiolateral radicular area adjacent to the severely distended pulp chamber. A gutta-percha point inserted into the sinus tract traced to this same region. The diagnosis was normal pulp coincident with DI Oehlers type 3 with pulp necrosis and chronic apical abscess. RESULTS: Despite a concerted effort to limit the root canal therapy to only the necrotic canal, its proximity to the normal canal obviated this possibility, entailing endodontic treatment of the entire root canal system. The necrotic pulp space was subjected to sustained irrigation with 5.25% sodium hypochlorite and then completed with 17% ethylenediaminetetraacetic acid. A bolus of gutta-percha was used to create an apical barrier, and then the remainder of the enlarged pulp space was obturated with injectable thermoplasticized gutta-percha. At a 4.5-year recall, there was no clinical and radiographic evidence of infection. CONCLUSIONS: Endodontic success was accomplished with meticulous efforts of disinfection. Thermoplasticized gutta-percha can offer utility for obturation of anatomically complicated pulp spaces. The use of the dental operating microscope is an invaluable aid for discernment of the intricacies of teeth affected with DI type 3 variant and can enhance clinical outcomes.

RESUMO

Ameloblastomas are benign aggressive odontogentic tumors that exhibit insidious growth rates with attainment of extensive dimesions. Because ameloblastomas are not usually symptomatic until late in their clinical course, few are detected early. This article reports an atypical case of a small, painful ameloblastoma arising between the roots of the mandibular left canine and lateral incisor in a 66-year-old female. The patient underwent an en bloc resection of the mandible, and no recurrence was demonstrated on an 11-month recall examination. Histopathology revealed a "hybrid" ameloblastoma with a pronounced desmoplastic pattern and acanthomatous changes. Practitioners should be vigilant for diminutive radiolucent lesions of the jaws with poorly defined borders. Timely recognition and intervention of ameloblastomas may improve treatment outcomes.

RESUMO

Five examples of radiographic oddities, culled from the records of private dental practitioners, are presented. Two cases feature radiographic manifestations of systemic disease, and three cases display anomalous oral findings. Each illustration is furnished with a short narrative and interpretation.
