초록
Ambiguity in the root morphology of the mandibular second molars is quite common. The most common root canal configuration is 2 roots and 3 canals, nonetheless otherpossibilities may still exist. The presence of accessory roots is an interesting exampleof anatomic root variation. While the presence of radix entomolaris or radix paramolarisis regarded as a typical clinical finding of a three-rooted mandibular second permanentmolar, the occurrence of an additional mesial root is rather uncommon and representsa possibility of deviation from the regular norms. This case report describes successfulendodontic management of a three-rooted mandibular second molar presenting withan unusual accessory mesial root, which was identified with the aid of multiangledradiographs and cone-beam computed tomography imaging. This article also discussesthe prevalence, etiology, morphological variations, clinical approach to diagnosis, andsignificance of supernumerary roots in contemporary clinical dentistry.
