Overlooking this hidden canal can lead to root canal treatment failure.

A cause of endodontic failure: failure to locate of the Middle Mesial Canal MMC. During root canal treatment—particularly on upper and lower first molars—an additional canal is often present; in the case of lower molars, this canal is located in one of the roots and is known as the "middle-mesial canal". This canal must be located and disinfected before being obturated to ensure the success of the endodontic treatment. Join me as we look at a case study, covering everything from caries removal to the complete restoration of the tooth. Importance of Middle Mesial Canal 🦷 -Prevalence: Reported in roughly 1% to 28% of mandibular first and second molars depending on the detection methods and population studied. -Detection: Often hidden beneath a small wall of dentin. Dentists use advanced tools like Cone-Beam Computed Tomography (CBCT) and surgical microscopes to spot them. -Risk: Missing this hidden canal during root canal therapy can leave bacteria behind and lead to treatment failure.
