Abstract

Abstract: PURPOSE: To evaluate the usefulness of mineral trioxide aggregate (MTA) in sealing affected roots within the cystic cavity. METHODS: A retrospective study of 12 patients treated between January 2009 and January 2012 was performed. Criteria of inclusion was simultaneous application of MTA in affected roots during curettage of jaw cystic lesions, root canal therapy completed within one week after curettage of jaw cystic lesions. All of the included subjects were strictly followed up, the lesion and involved teeth were evaluated accordingly. RESULTS: A total of 30 teeth in 12 patients were included. None of them reported with tender to percussion or mobile teeth. Dental periapical films revealed periapical bone healing with bizarre trabeculae formation. None of them had relapse. Tooth preservation rate was 100%. CONCLUSIONS: MTA is very good in achieving perfect apical sealing. The apical sealing turned out to be better if retrograde sealing was performed simultaneously with curettage of cystic lesion. The involved teeth are more likely to be preserved yet allowing a complete curettage with no relapse.
