Pulp canal obliteration as a trauma sequela is best described as

Pulp canal obliteration is the pulp’s calcific response to trauma, where dentin-like tissue is deposited within the pulp chamber and root canal, progressively narrowing or obliterating the canal. This often occurs after blunt trauma in a developing tooth and the pulp remains alive in many cases, so it is not necrosis with infection. It’s different from arrested root development, which is a halt in root formation, and from dilaceration, which is a curved/root deformity caused by injury. The description, then, is a calcific metamorphosis of the pulp leading to canal obliteration.
