Abstract:

One of the teeth with the most complex root system and root channel anatomy are maxillary first molars. Maxillary molars having three separate mesiobuccal canals ending with three separate foramen are extremely rare. When planning endodontic treatment in these teeth, the clinical and radiographical anatomy should be considered. In clinical practice, cone-beam computed tomography is one of the most important diagnostic tools for fully assessing this rarely encountered morphology. The aim of this report is to present a case of a left maxillary first molar with three separate mesiobuccal channels ending with three separate foramen and to emphasize the importance of thorough assessment of the anatomy of the root channel before treatment.
