| Popis: | This historical cohort study follows on a previously reported trial, with the aim of assessing the outcome for teeth with root perforations managed by the orthograde placement of mineral trioxide aggregate (MTA) and identifying potential outcome factors for such treatment with a larger sample size and longer follow-up periods than in the first phase of the project.The treatment outcomes of 64 root perforations repaired between 2000 and 2012 with MTA were investigated. The root perforations were located in different areas of the root. Calibrated examiners assessed clinical and radiographic outcomes by using standardized follow-up protocols 12-107 months after treatment (median, 27.5 months). Preoperative, intraoperative, and postoperative information was evaluated. The outcomes were dichotomized as healed or diseased.Of the 64 teeth examined (85% recall rate), 86% were healed. The univariate analyses (χ(2) tests) identified 2 potential prognostic factors, experience of the treatment providers (odds ratio, 2.14; 95% confidence interval, 0.39-11.74; P.01) and placement of a post after treatment (odds ratio, 0.06; 95% confidence interval, 0.01-0.27; P.01). In the multivariate stepwise logistic Cox regression, none of the potential prognostic factors displayed a significant effect on the outcome at the 5% level.MTA appears to have good long-term sealing ability for root perforations regardless of the location. The results of this historical cohort study confirm the results of the first phase of this project. |
