Abstract:
A comprehensive knowledge and understanding of root canal anatomical variations are essential for successful root canal treatment. Mandibular molar teeth show considerable variations in their external and internal radicular morphology that require special attention from dental practitioners to provide the best clinical outcomes to the patients. This report aims to present root canal treatment of a mandibular first molar that has six separate root canals (three root canals in the mesial roots and three in the distal roots [236 M3 D3]). This report points out the importance of proper exploration for identifying additional canals in mandibular molars.
