Endodontic management of radix entomolaris: Case reports

Abstract

The root canal treatment of a mandibular molar with aberrant canal configuration can be diagnostically and technically challenging. This report discusses endodontic treatment of three mandibular molars with radix entomolaris (RE). The first case report discusses bilateral radix entomolaris in mandibular first molars. An additional aberrant root canal anatomy of the middle mesial canal, which was confirmed by cone beam computed tomography (CBCT) images, is also described. This case report highlights the usefulness of CBCT imaging for accurate diagnosis and management of the unusual canal morphology. The second case report discusses a mandibular first molar with three roots (one mesial and two distal) and four canals (two in mesial and one in each distobuccal and distolingual root). If present, an awareness of unusual root canal morphology can contribute to the successful outcome of root canal treatment.
