Continued root formation after replantation and root canal treatment in an avulsed immature permanent tooth: a case report

Dent Traumatol. 2010 Apr;26(2):182-5. doi: 10.1111/j.1600-9657.2010.00864.x.

Abstract

This case report describes the continued root formation following replantation and conventional root canal therapy of a traumatically avulsed open-apex tooth with suppurative apical periodontitis. A 7-year-old male patient had an avulsed upper left central incisor (tooth 21) replanted approximately 50 min after traumatic avulsion. A root canal procedure was initiated due to pulp necrosis and periapical abscess detected in the follow-up period. After endodontic treatment with calcium hydroxide (Ca(OH)(2)) dressing, a normal root length developed including an apical segment beyond the hard tissue barrier. Regeneration of the root occurred without pathology or ankylosis at 1-year of follow up.
