[ case report; endodontic treatment of 4-rooted mandibular second molar tooth]

ABSTRACT

The knowledge of root canal anatomy and morphology and understanding the cases with variations from the normal anatomy are necessary to achieve success in endodontics. No cases with four separate roots in the mandibular second molars have been reported sofar. The purpose of this study was to report the presence of four separate roots in a mandibular second molar in a patient. A 29 year old male patient was referred for root canal therapy of a mandibular right second molar with a history of emergency treatment. The diagnostic radiograph revealed the presence of four separate roots. The presence of five orifices was confirmed in the pulp chamber after access cavity completion. Conventional root canal treatment was performed in the five root canals of the tooth. The knowledge of common anatomic configurations and possible variations in root canal morphology is one of the important factors for a successful root canal treatment. Report of uncommon cases can motivate the dentist to always perform exact radiographic and clinical evaluations of the teeth and consider the rarities during root canal treatment
