I think you transported the canal. You should've PreFlared at the Coronal & Middle parts of the root before starting Apical preparation.
Try to Pre-Bend the file (Size 15 or 10) & Re-negotiate the Canal.
Good Luck :)

I think this iatrogenesis should not make you lose confident in yourself...instead it should make you determined to prevent it from happening again...I think the lesson is : if you are using hand files....you have to recapitulate with #15 between files...and this problem will be almost nil if you use RNTFs.....I wounder why did not you do that? I am expecting you all to be using them in the 5th year.
