超声技术应用于一次性根管治疗92例临床分析

Use of ultrasonics in one-off root canal therapy: A report of 92 cases

摘要: 目的: 观察利用超声技术进行一次性根管治疗的疗效。方法: 用超声法加逐步后退法交替应用进行根管预备,并一次完成治疗。结果: 治疗的104颗患牙随访92例共92颗牙,无症状74例(80。4%),轻中度反应15例(16。3%),重度反应3例(3。3%)。结论: 采用超声技术应用于一次性根管治疗有效地降低了其术后急性反应,亦扩大了适应证范围。

Abstract: Objective: To observe the effect of the one-off root canal therapy using ultrasonic technology.Methods: The ultrasonic technology was used to manage root canal enlargement and the treatment was completed at once.Results: In the 92 cases followed up,74 cases presented no symptom(80.4%),15 cases had light or medium reaction(16.3%)and 3 cases heavy reaction(3.3%).Conclusions: Using ultrasonic technology to treat one-off root canal can greatly reduce the flare-up after operation,and enlarge the scope for the one-off root canal treatment.
