【摘要】：【目的】探讨机用镍钛器械对牙根管治疗患儿应激反应及治疗效果的影响,分析其可能作用机制。【方法】选择2015年3月-2017年3月行根管治疗术乳牙牙髓病或根尖病患儿60例(60颗牙)为研究对象,采用随机数字表法分为观察组和对照组各30例(30颗牙),对照组采用手用镍钛扩大挫,观察组采用机用镍钛器械,比较两组患儿根管预备效果、应激反应、疼痛程度、填充效果及远期疗效等指标。【结果】观察组根管根治术患儿根管预备时间明显短于对照组(P0.01),根管偏移等根管形态变化发生率6.67%,明显低于对照组26.67%(P0.05);龈沟液肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)等含量明显低于对照组(P0.05,P0.01);根管预备中、根管预备后疼痛率均明显低于对照组(10.00%vs 33.33%,3.33%vs 23.33%,P0.05);术后1周,观察组患儿恰填率93.33%,明显高于对照组70.00%(P0.05);随访6个月,观察组根管术成功率90.00%,明显高于对照组66.67%(P0.05)。【结论】机用镍钛器械有助于缓解牙根管治疗患儿疼痛程度,提高临床疗效,可能与抑制手术应激反应有关。
[Abstract]:[objective] to investigate the effect of machine nickel titanium instrument on stress response and therapeutic effect of children with root canal therapy. [methods] 60 children with primary dental pulp or apical disease underwent root canal therapy from March 2015 to March 2017. The experimental group was randomly divided into two groups: the observation group (n = 30) and the control group (n = 30). The patients in the control group were divided into two groups: the control group (n = 30) and the control group (n = 30), and the control group (n = 30) were divided into two groups: the control group (n = 30) and the control group (n = 30). [results] the preparation time of root canal in the observation group was significantly shorter than that in the control group (P 0.01), and the incidence of root canal deviation was 6.67, which was significantly lower than that in the control group (26.67%, P 0.05), and the gingival crevicular fluid tumor was bad. In root canal preparation, the contents of dead factor- 伪 TNF- 伪, interleukin-6, interleukin-1 尾 and interleukin-1 尾 IL-1 尾 were significantly lower than those in control group. The rate of pain after root canal preparation was significantly lower than that in the control group (10.00 vs 33.333.33 vs 23.33P0.05), and at one week after operation, the accurate filling rate in the observation group was 93.33 and was significantly higher than that in the control group. The success rate of root canal operation in the observation group was 90.00g, which was significantly higher than that in the control group (66.67). [conclusion] Nickel-titanium instrument can relieve the pain and improve the clinical efficacy of root canal therapy, which may be related to the inhibition of stress response.
