Clinical management of multiple mesial and distal canals in mandibular first molars - A case report

Thorough cleaning and shaping and followed by three-dimensional obturation is secret to successful clinical endodontics. Therefore, it is imperative that aberrant anatomy should be identified before and during root canal treatment. Multiple case reports of aberrant canals morphology in the mesial root of mandibular first molar have been documented. However, fewer studies have discussed the occurrence of a third distal canal in distal root of mandibular molars. The incidence of middle distal canal is much lower than that of middle mesial canal. This article presents the two rare case reports describing of multiple canals in mandibular first molars i.e 3 distal canals in one case report and 3 mesial canals in another.
