Pulp canal obliteration (original) (raw)

Pulp canal obliteration (also termed pulp chamber obliteration or root canal obliteration) is a condition which can occur in teeth where hard tissue is deposited along the internal walls of the root canal and fills most of the pulp system leaving it narrowed and restricted. Signs and symptoms of obliteration include: * Yellow tooth discoloration * Lack or response to pulp sensibility test (e.g. ethyl chloride, electric pulp test) * Lack of visible radiolucency where pulp system should be on radiographs (x-rays)
