摘要
目的 观察超声冲洗在死髓牙根管预备中的效果。方法 将 14 4例患者的 14 4颗患牙 ,随机分为 2组 ,在根管预备时分别采用超声冲洗和注射器冲洗 ,观察 1周内的术后反应。结果 超声治疗组术后反应的发生率为 18 0 6 % ,轻度反应占13 89% ,中度反应占 4 17% ,无重度反应发生 ;对照组术后反应的发生率为 4 0 2 8% ,轻度反应占 2 5 0 0 % ,中度反应占12 5 0 % ,重度反应占 2 78%。
Objective To investigate the effects of ultrasonic irrigation in root canal preparation of necrotic teeth.Methods 144 teeth of 144 patients were equally divided into two groups at random. Ultrasonic irrigation and syringe irrigation were used separately during the canal rinsing.Results 18.06% of patients in ulatrasonic group felt uncomfortable or painful and 40.28% of the patients in the control group felt comfortable or painful. Conclusion Root canal irrigation with ultrasonic might greatly decrease or lighten the periapical reaction in the root canal therapy of necrotic teeth.
