Endodontic management of radix entomolaris: Two case reports

Mandibular first molars show most of the anatomical variations not only in the number of canals but also in the presence of number of roots and their morphology. The presence of additional root either lingually or buccally in addition to two roots is one of the complex morphological variations. Diagnosis, identification, and treatment of these variations need adequate knowledge of root and root canal anatomy and configurations which can contribute to the better outcome. This case report discusses the endodontic treatment of two mandibular first molars with a radix entomolaris (RE), which are rare macrostructures. The prevalence, the external morphological variations, and internal anatomy of the RE are described

A clinical approach to the successful management of variations of middle mesial canals: A case series

The possible variations of anatomical and morphological characteristics of the teeth are very important especially for the endodontic practitioners for successful treatment. Mandibular molars are most commonly affected by dental caries and require endodontic treatment. Mandibular molars exhibit variations in its internal anatomy; one among those is the presence of an extra canal in the mesial root called as middle mesial (MM) canal. Detection of these minute canals requires a proper clinical knowledge and radiographic examination. This article presents the treatment of three cases of mandibular first molars with MM canals without the aid of any magnification devices
