Identification and clinical management of extra root in mandibular first molars: A series of case reports

The radix entomolaris/paramolaris is the major anatomical variant in mandibular first molars. If present, an awareness and understanding of this unusual root and its root canal morphology can contribute to the successful outcome of root canal treatment. Hence, it is essential to anticipate and find all roots and root canals during root canal treatment with the help of proper angulations and interpretation of intraoral periapical radiographs. This case series discusses the detection and clinical management of five mandibular molars with extra root and root canal anatomy
