MTA根尖屏障术用于根端囊肿中根尖孔未闭合牙的临床疗效评价
|
Abstract:
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3~5 mm,后同时从冠方及根方加压充填MTA于根尖区3~5 mm,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
