Mandibular First Molars with Middle Mesial and Middle Distal Canals – A Report of Two Cases

Meticulous cleaning, shaping and filling of the root canal system are requisites for a successful root canal treatment.. Unfortunately, canal preparation is adversely influenced by the highly complex, intricate and variable root-canal anatomy. Thorough knowledge of root canal morphology and unusual anatomy of the tooth is crucial for the practitioner. Over the years, there have been numerous studies that describe the morphology of teeth, including mandibular first molars. These reports have shown that mandibular first molars have three or four canals. However, unusual root canal anatomy associated with the mandibular first molars has been reported in several studies and case reports. The following article reports the identification and systematic management of a middle mesial canal and middle distal canal in mandibular first molars in two cases.
