Prevalence of Middle Mesial Canals and Isthmi in the Mesial Root of Mandibular Molars: An In Vivo Cone-beam Computed Tomographic Stud

3.75 (4 votes)

Many studies have investigated the morphology of the mandibular molar, but the prevalence of the middle mesial (MM) canal in the mesial root of the mandibular molar is still the subject of controversy. In addition, in previous literature, a true MM canal has not been clearly distinguished from an isthmus between the mesiobuccal and mesiolingual canals. 

At the conclusion, participants should be able to:

  • Describe the importance of detecting and cleaning the mid mesial canals and isthmus in mandibular molars.
  • Discuss the use of CBCT in detection of mid-mesial canals and isthmus in mandibular molars.
  • Discuss the prevalence and configuration of mid- mesial canals and isthmus in the mesial roots of mandibular molars.
