Case 25 Lateral canals - many times the key to success

Pre-operative x-ray tooth #5 


Patient presented with symptomatic #5.  X-ray shows lateral lesions on both roots, one to the distal and one to the mesial.


Post-operative x-ray #5

Note: both lateral radiolucensies


Lateral canals in both roots


14 month post-operative x-ray #5

Tooth is asymptomatic and lateral radiolucensies are healed.







Comment: Lateral lesions on teeth with no evidence of fracture usually indicate a lateral canal system. If root canals are done and the lesions fail to heal, I would generally retreat before contemplating other options, i.e. surgery or extraction.
