How to identify the number of accessory canals while doing RCT?
(Content under development)
The following question was submitted by a practising dentist: How to identify the number of accessory canals while doing RCT?
Dr. Mary Dabuleanu from Dabuleanu Dental provided these initial comments for consideration:
One never quite knows exactly how many accessory canals are present when you embark in a case. The pre-operative X-Ray may show an area of widened periodontal ligament space along the side of a root, which proves to be a lateral canal on the final X-Ray.
If the root anatomy is tortuous, one can suspect some accessory canals around the sharp bend of the root. Also, bulbous roots tend to have apical ramifications. When irrigants are left to soak in the canal system for an adequate amount of time, you can better fill the accessory canals.
