Management of root resorption with mineral trioxide aggregate complicated by a luxation injury: report of a case with six-year follow-up.
J Pak Med Assoc Jan ;67(1):134-6.

Trauma to the oral region occurs frequently, comprising 5% of all injuries. The most common dental injuries are lateral luxations which can be seen with a prevalence of up to 27% among dental injuries. Ectopic eruption of maxillary canines can lead to root resorption on maxillary lateral incisors especially on apical and middle thirds of the roots. Half of these resorbed lateral incisors show severe resorption, in which the pulp is exposed. This case report describes non-surgical treatment with mineral trioxide aggregate (MTA) and a six-year follow-up of a maxillary lateral incisor, resorbed by ectopic eruption of the canine and affected by lateral luxation injury. The tooth was asymptomatic, and radiographic examination showed that the resorbed region had been successfully repaired with new hard tissue deposition within the six-year follow-up. MTA can be considered an effective repair material in nonsurgical treatment of this type of root resorption.
