Locating Middle Mesial Canals
Avoid Missing a Canal in Hiding
The mandibular molar is traditionally described as a tooth with two canals in the mesial root. However, studies have shown that their anatomy can vary significantly, and a third canal is found in 15-25% of all cases. When working without magnification, it is likely that the middle mesial canal will be missed. However, the application of magnification and ultrasonics to trough between the mesiobuccal and mesiolingual canals with a diamond coated insert (E2D or E6D) can increase the probability of finding the middle mesial canal by up to 50%.
Step-by-Step Calcified Canal Location
2 – The dentin covering the pulp chamber floor and its mesial wall must be completely removed.
3 – Using a square section file, negotiate the middle mesial canal penetration, taking advantage of the sturdiness of these instruments.
1. Create a groove connecting the mesiobuccal and mesiolingual canals.
2. Locate the middle mesial canal orifice along the groove.
3. Use an appropriate file to negotiate and prepare the canal.
