【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。
[Abstract]:Objective: to observe the clinical effect of MTA apical barrier in the treatment of patent teeth with apical foramen in root cyst. Methods: twenty-six teeth of 24 patients with apical foramen incomplete closure with root cyst were studied. The focus teeth were all maxillary anterior teeth, and routine root canal preparation and disinfection were performed before operation. After scraping the cystic wall, the apical part of the root was repaired and the root tip was prepared by ultrasound. Then the MTA was filled with pressure from the crown side and the root square at the same time. One week later, MTA was completely rigid to complete the root canal filling and the repair and treatment of the root canal was completed. The root canal was filled with the root canal from the coronal side and the root square at the same time. Results: all the 24 patients were successful, no recurrence was found in 2 years after operation, and the teeth and jaws healed well. Conclusion: MTA for apical foramen unclosed teeth with root cyst has a good clinical effect, and it is easy to operate and has no adverse stimuli. It is an ideal method for the treatment of apical cyst in patients with apical foramen unclosed teeth with root cyst.
