INFECTED ROOT CANAL TREATMENT OF MAXILLARY MOLARS USING A MICROSCOPE AND CONE-BEAM COMPUTED TOMOGRAPHY

Abstract

It is well known that root canal treatment of maxillary molars is made difficult by root fusion and complicated root morphology. In addition, the root apices of maxillary molars are in close proximity to the maxillary sinus, often causing odontogenic maxillary sinusitis. Two cases of this type of molar, in which a microscope and cone-beam computed tomography (CBCT) were needed for proper root canal treatment, are reported. Satisfactory results were obtained in both cases.
