目的:探讨应用显微镜联合超声、三氧化矿物凝聚体的根尖手术在难治性慢性根尖周病治疗中的临床疗效。方法:选取15例患者17颗慢性根尖周炎的患牙,经常规根管治疗无效,进行根尖切除术和根尖倒充填术,进行术前、术中、术后护理及随诊观察。结果:本组17颗患牙,其中16颗手术治疗后无自觉症状且完全恢复功能,组织附着紧密;1颗经治疗后咀嚼基本正常,疼痛消失,根尖阴影缩小。结论:应用显微镜联合超声、三氧化矿物凝聚体的根尖手术在难治性慢性根尖周病治疗中,具有满意的疗效。护士在整个过程中应有较强无菌观念,熟练地掌握操作步骤,迅速、准确地配合医生,减少感染机会,提高手术成功率。
Objective: To investigate the clinical effect of microsurgical combined ultrasound and apical surgery of trioxide mineral aggregates in the treatment of refractory chronic apical periodontitis. Methods: Twenty-seven patients with chronic periapical periodontitis were selected from 15 patients. After conventional root canal therapy, root apical resection and apical filling were performed. Preoperative, intraoperative and postoperative care and follow-up were observed . Results: The group of 17 teeth, including 16 after surgery without symptoms and fully restored function, tissue adhesion; a chewing after treatment was normal, the pain disappeared, the narrowing of the apical shadow. Conclusion: Microscope combined with ultrasound, apical three oxide mineral aggregate in the treatment of refractory chronic apical week, with satisfactory results. Nurses in the whole process should have a strong concept of sterilization, proficiency in operating steps, quickly and accurately with the doctor, reduce infection opportunities and improve the success rate of surgery.
