Signs and symptoms of obliteration may include Yellow tooth discoloration, Lack or response to pulp sensibility test (e.g. ethyl chloride, electric pulp test.(1) Pulp necrosis has also been reported as a complication with ranges varying from 1% to 16%(2). Periapical lesion develops in a range of 7.3% to 24% in these cases up to 4 years after initial traumatic injury, especially in completely calcified teeth(2).
