Case 30 Crazy canal system

Pre-operative x-ray #18

Symptomatic # 18 Small occlusal composite filling. Apical breakdown noted.

Photo #18 after accessing
Photo #18 note: only 1 mesial

Initial access 3 canals but...

Only one mesial and two distal canals

Immediate post-operative x-ray #18

Just remember when accessing for a root canal, the canals are not always going to be where they "should" be. The floor of the chamber is usually grey, and anything outside the grey is usually a perforation.
