Localização e obturação do canal cavo interradicular: a importância do diagnóstico e da proservação

Abstract

Endodontic treatment is a procedure that is daily performed by dentists. It’s success depends on the anatomical knowledge that the professional has, because there are countless anatomical variations, for example: lateral, accessory, secondary and furcation canals. The furcation canal is one of them, been very important that the professional knows about the possible existence. On this paper, we will report a case of location and sealing of the furcation canal in tooth 37, which was discovered when it shows a furcation lesion after endodontic treatment. M.V.T.P, 22 years old, asymptomatic, attended at the dental clinic of Unicesumar for a routine appointment. After radiographic examinations, was verified a possibility of having a cementoblastoma in the distal root of tooth 37. The chosen treatment was apicectomy of the root and the lesion. Before the surgery, we did an endodontic treatment in the tooth using rotary instrumentation. Months after the procedure, when the patient returned, an extensive lesion in the furcation was verified radiographically, then, it was discovered that the lesion was provenient from the furcation canal. We did a new coronary opening in the tooth, located and seald the canal.
