摘要/Abstract

摘要： 目的通过MTA封闭根尖,保存颌骨囊性病变受累牙,探索其在颌骨囊性病变保存性外科治疗中的应用价值。方法：回顾2009年1月—2012年1月收治的12例、30颗受累牙的颌骨囊性病变病例,在完成颌骨囊性病变刮治术的同时,采用MTA封闭受累牙根尖,术后1周完善根管治疗,随访分析受累牙以及颌骨囊性病变术后愈合情况,评价其临床疗效。结果：12例患者平均随访3.1 a,30颗受累牙无自发痛和叩痛、无松动、脱落,X线片示牙根周围骨小梁重建,颌骨囊性病变愈合,无1例复发,受累牙保存成功率为100%。结论：MTA具有良好的封闭性能,在颌骨囊性病变治疗中,同期封闭受累牙根尖联合根管治疗,保存牙成功率高,同时不影响颌骨囊性病变的治疗效果。

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.
