15-17ĬM is a common outcome of trauma frequently associated with anterior teeth of young adults and is characterised by partial or total obliteration of the root canal. Treatment protocols and exact intervention times for the treatment of CM remains controversial and a challenge for even the skilled clinician. 1,9 However, the pulp status within partially obliterated canals may eventually lead to apical pathology requiring treatment. 6-8Īsymptomatic teeth presenting with CM do not initially require treatment other than annual review. 5 CM can be clinically detected as early as three months after injury but remains undetected in most cases for up to a year after trauma. This calcification of the pulp canal space results in a loss of translucency leaving the crown with a yellow discolouration ( Fig. 1,2 Although the exact mechanism by which the canal obliterates is unknown, it is believed to be related to neurovascular damage and deposition of hard tissue within the canal. 1A-C) is a common occurrence following concussion and subluxation injuries.
