Hi
This patient presented with a massive periapical lesion and lots of pain.

I completed the endo with the help of the Nd:YAG laser in one appointment as there was no drainage and the canals were dried completely with the laser.

The patient did not want as a crown as I wasn’t sure how the lesion would resolve. I sealed the access cavity with a temp. The patient only came back now, six months later with a crack mesiodistal up to the level of the bone loss. If I had placed a crown at the time the tooth would probably still be functional, now it is in the bin…

I found the amount of bone regeneration very interesting. The crack must have been there for a while to cause that much bone loss. With hindsight, a temporary crown would have been the answer?
Take care
Etienne
