摘　　要：目的：观察MTA根尖屏障术治疗根端囊肿中根尖孔未闭合牙的临床疗效。方法：临床确诊为根尖孔未完全闭合伴发根端囊肿24例患者的26颗牙为研究对象,病灶牙均为上颌前牙,术前常规根管预备及消毒,术中刮除囊壁后修整根尖并用超声倒预备根尖部3-5mm,后同时从冠方及根方加压充填MTA于根尖区3-5mm,1周后待MTA完全硬固,完善根管充填及修复治疗。结果：24例患者均取得成功,术后2年无复发,且病灶牙与颌骨均愈合良好。结论：根尖孔未闭合牙伴发根端囊肿患者应用MTA行根尖屏障术取得较好的临床疗效,且操作方便,无不良刺激反应,是一种较理想的治疗方法。Objective：To evaluate the clinical effect of MTA apical barrier technique used in the open apices teeth accompanied with radicular cyst.Methods：Twenty-four patients diagnosed with open apices teeth accompanied by radicular cyst were included in this study.All teeth were the upper anterior teeth.Before the surgery all teeth were cleaned and shaped.In the surgery,the open apices were shaped and pluged with 3-5mm MTA after removing the cyst.Until the MTA completely set about one week later,the root filling was performed in the open apices teeth.The patients were followed-up for at least two years.Results：Good result was achieved in all cases.The two-year postoperative X-ray films showed that the apical radiolucent areas of the teeth with pre-existing radicular cyst completely disappeared.No new radiolucency was found around the roots.Conclusion：MTA apical barrier technique is effective in the treatment of open apices teeth accompanied with radicular cyst.
