Purpose: to evaluate endodontically treated teeth with root perforations which were repaired exclusively with MTA, in order to determine MTA treatment success
N= 21 teeth
Materials/Methods:
•Root perforation repaired using MTA with at least 1 year between tx and follow up included
•Teeth had been treated using RD and conventional RCT
•Repair process: defect carefully irrigated and dried if necessary, MTA applied to the site when bleeding controlled, obturation (cold lateral, WV and injectable GP)
•Pre- and intraoperative information pertaining to clinical variables were gathered.
•Follow-up examinations performed at different time intervals ranging from 12 to 65 months after treatment, with a median follow-up period of 33 months. PAI score assessed.
•A case was classified as ‘‘healed’’- No indication of apical periodontitis (PAI <2), no radiolucency adjacent to the perforation site, no continuing root resorption, no clinical signs and symptoms, and no loss of function. Outcome was classified as ‘‘diseased’’- clinical signs and symptoms, apical periodontitis (PAI >3), radiolucency adjacent to the perforation site, or signs of continuing root resorption.
•None of the treating dentists were endodontists
Most highlighted Results:
•An overall rate of 86% healed.
•Differences were recorded relating the outcome to the recorded pre, intra, and postoperative variables but were none significant. (Fig.)
Clinical significance:
MTA provide a biocompatible and long- term effective seal for root perforations in all parts of the root.
