The root canal treatment of a mandibular molar with additional root can be technically and diagnostically challenging. Mandibualr molars can have an additional root located buccally (radix paramolaris) or lingually (radix entomolaris). If present, knowledge and understanding of this unusual root and it´s root canal morphology can contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of three mandibular molars with radix entomolaris (RE). The prevalence, the external morphological variations and internal anatomy of the paramolaris and entomolaris are explained. Clinicians must be aware of these unusual root morphological variations of radix entomomolaris (RE) in terms of root inclination and root canal curvature. Preoperative radiological assessment from different angles, clinical evaluation of a root canal number and morphology using various diagnostic methodologies, a proper access preparation, and thorough examination of the pulp chamber to locate and debride all the canals are important.
