Endodontic Treatment of Permanent Mandibular First Molar with 4 Roots and 5 Canals-Clinical Case Reports

Abstract

Endodontic management of mandibular molars is a challenging task due to its varied morphology of roots and root canals. A mandibular permanent first molar with additional buccal root (Radix paramolaris) and additional distal root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of endodontic therapy. The detail knowledge of the root morphology and canal anatomy allows the clinician for accurate location of the extra roots and canals and accordingly the refinement of the access cavity for the stress free entry of complex anatomy. Hence, for a successful endodontic therapy, clinician must be aware of the external and internal anatomic variations. The aim of these clinical case reports is to present and describe the unusual presence of two separate mesial roots, distal roots and 5 root canals in permanent mandibular first molar diagnosed during routine endodontic therapy.
