镍钛器械根管预备治疗慢性根尖周炎的术后反应及远期疗效观察

Observation on the Postoperative Reaction and Long-Term Effect of Root Canal Preparation with Ni-Ti Instrument in the Treatment of Chronic Periapical Periodontitis

目的:观察镍钛器械根管预备治疗慢性根尖周炎的术后反应及远期疗效。方法:选取2022年1月~2022年7月本院收治的68例慢性根尖周炎患者为研究对象,以随机数字表法分为对照组与观察组,各34例,分别采用不锈钢器械与镍钛器械实施根管预备治疗,对比两组术后反应与远期疗效。结果:观察组根管预备时间短于对照组,根管弯曲度高于对照组;术后疼痛程度与并发症总发生率均低于对照组,差异有统计学意义(P<0.05);但两组远期疗效对比,差异无统计学意义(P>0.05)。结论:镍钛器械根管预备治疗慢性根尖周炎的远期疗效显著,并且可明显缩短根管预备时间,提高根管弯曲度,减轻患者术后疼痛,降低术后并发症发生风险。

Objective:To observe the postoperative reaction and long-term effect of root canal preparation with nickel-titanium instruments in the treatment of chronic periapical periodontitis.Methods:68 patients with chronic periapical periodontitis admitted to our hospital from January 2022 to July 2022 were selected as the study subjects.They were divided into the control group and the observation group by random number table method,with 34 cases in each group.The root canal preparation treatment was performed with stainless steel instruments and nickel-titanium instruments respectively,and the postoperative reaction and long-term effect of the two groups were compared.Results:The root canal preparation time in the observation group was shorter than that in the control group,and the root canal curvature was higher than that in the control group;The degree of postoperative pain and the total incidence of complications were significantly lower than those in the control group(P<0.05),there was no statistically significant difference between the two groups in long-term efficacy(P>0.05).Conclusion:Ni-Ti instrument root canal preparation has a significant long-term effect in the treatment of chronic periapical periodontitis,and can significantly shorten the root canal preparation time,improve the root canal curvature,reduce postoperative pain,and reduce the risk of postoperative complications.
