Mandibular molars can have an additional root located I ingually (the radix entomolaris) or buccally (the radix paramolari s). If present, an awareness and understanding ofthis unusual mot and its root canal morphology can con tribute to the soutcome of voot cunal treatment. This report discusses endodontic treatment ofmandibu lar molars With Oiboth Of which in the Indian population. The prevalence, the external morphological variations and internal anatomy of the radix cntomolaris and paramolaris arc described.
