Endodontic management of mandibular first molar with 4 roots and 6 canals – A case report

Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Variations in the anatomy are an acknowledged characteristic feature of mandibular permanent molars. Ingle et al. stated that incomplete obturation of the root canal system, is the major cause for failure of the root canal treatments.2 Hence, the correct location, vigorous instrumentation and three dimentional obturation of all canals are important procedures procedures. Fabra–Campos studied 145 first mandibular molars and found that 2.75% of the teeth had five canals.3 This case report describes endodontic therapy on 4-rooted, 6-canaled mandibular first molar.
