MTA apical plugs in the treatment of traumatized immature teeth with large periapical lesions

Dent Traumatol. 2011 Feb;27(1):59-62. doi: 10.1111/j.1600-9657.2010.00941.x. Epub 2010 Dec 5.


This case report describes the management of a late-referral case of periapically involved, traumatized immature permanent incisors by endodontic treatment and the use of mineral trioxide aggregate (MTA) apical plugs. A 10-year-old boy was referred to the clinic with a chief complaint of pain in his maxillary central incisors, which had experienced subluxation trauma 2 years earlier. Periapical radiograph of the teeth showed incomplete root development with wide-open apices and large periradicular lesions. The canals were gently debrided using K-files in conjunction with 2.5% NaOCl irrigation and 2% chlorhexidine for final flush. The root canals became asymptomatic after employing the same endodontic regimen for three visits. MTA plugs were placed in the apical area of the root canals, and the rest of the canal space was obturated by warm compaction of gutta-percha and AH Plus sealer. Resolution of the large periapical lesions was observed 2 months after treatment. At 18 months, the periapical areas revealed radiographic evidence of bone healing. Following successful removal of the toxic content of the root canal, placement of MTA plugs resulted in both healing of the periradicular radiolucency and regeneration of the periapical tissue.
