in this video, i show you how i usually do access preparation in mandibular molar. some of the guidelines are follows:
1. In 35% of cases, four canals are present.47,81 The distal root contains two canals, one in the buccal and the other in the lingual position
2. The second distal canal is sometimes found in a separate root in the distolingual position. It is slightly smaller and mesial to the distobuccal root
3. Sometimes, the “extra” canal is found in the mesial root, which therefore contains three canals
4. The most salient fact that emerges from an examination of these anatomical variants is that the lower first molar frequently has two canals in the distal root. If it has only one, it is usually ribbonshape, elliptical, or kidney shaped, that is, buccolingually elongated
hope this information helpful,
thanks for watching!
