Case 38 2 canals often in distal root

Pre-operative x-ray #30

Patient was symptomatic and swollen.

File film #30

Second distal canal was located. 

Immediate post-operative x-ray #30

Retreatment was completed. Mesial canals were also retreated.

10 month check-up x-ray #30

Complete healing after ten months. 

Comments:  Always a choice between a surgical approach and retreatment on any root canal that is failing, if one is assured that a fracture is not the problem. Generally retreatment will confirm that either the canals have been poorly cleaned or other canals that have never been negotiated are present, as in this case of the distal root.
