|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.
