摘要 目的观察分析慢性根尖周炎患牙用机用镍钛旋转器械ProTaper根管预备的临床疗效。方法临床诊断为慢性根尖周炎的单根管患牙124例,随机分为实验组(ProTaper根管预备组)63例;对照组(不锈钢K锉根管预备组)61例。疗程间用氢氧化钙根管封药,1周后冷侧压法根管充填。观察对比两组根管预备术后疼痛和术后2年X线片和临床评定的治愈率。结果术后患者疼痛率ProTaper根管预备组为17.5%,K锉组为39.3%,两组比较差异有显著性。术后2年治愈率ProTaper根管预备组为68.6%,K锉组为64.0%。两组间治愈率比较差异无显著性。结论 ProTaper机用镍钛器械用于慢性根尖周炎根管预备与传统根管预备的远期治愈率差异无显著性,但ProTaper根管机械预备操作时间短,效率高,术后疼痛少,根管预备成形效果好。
