[摘要] 目的 探討机用镍钛器械在根管治疗中的应用价值,分析其优缺点。方法 方便收集该院2015年7月—2017年8月期间收治的120例根管治疗患者,根据治疗方式分为2组。对照组60例,通过手用不锈钢锉予以治疗,研究组60例,通过机用镍钛Hero642予以治疗,比较分析2组患者临床治疗效果。结果 比较根管预备时间,研究组为(5.9±0.97)min,对照组为(12.5±1.39)min,比较2组结果,差异有统计学意义(P<0.05)。比较根充情况,研究组适充、欠充、超充所占比例分别为95.0%(57/60),1.6%(1/60)、3.4%(2/60),对照组分别为76.7%(46/60)、8.3%(5/60)、15.0%(9/60),组间数据分析,差异有统计学意义(P<0.05)。另外,比较疼痛程度,研究组,35例1级,21例2级,3例3级,1例4级,对照组,17例1级,28例2级,10例3级,5例4级,研究组3级、4级所占比例低于对照组(P<0.05)。结论 根管治疗中,应用机用镍钛器械,不仅可缩短根管预备时间,而且可确保根充效果,缓解疼痛程度,应用价值高,可在临床推广并使用。

[Abstract] Objective This paper tries to investigate the application value of nickel titanium instruments in root canal therapy, and to analyze their advantages and disadvantages. Methods 120 cases of root canal therapy were convenient collected from July 2015 to August 2017 in this hospital. They were divided into 2 groups according to the treatment methods. The control group, 60 cases, through the hand with stainless steel files, the study group, 60 cases, through the use of nickel titanium Hero642 treatment, comparative analysis of the two groups of patients with clinical treatment effect. Results Compared with the time of root canal preparation, the study group was (5.9±0.97)min, and the control group was (12.5±1.39)min. The results of the two groups were significantly different, with statistical significance (P<0.05). Comparison of root canal filling, in the study group, well under charging, super charging proportion was 95.0%(57/60), 1.6%(1/60), 3.4%(2/60), the control group were 76.7% (46/60), 8.3% (5/60), 15.0% (9/60), there were significant differences(P<0.05). In addition, in the research group, the degree of pain, 35 cases of grade 1, grade 2 in 21 cases, 3 cases of grade 3, grade 4 in 1 case, the control group, 17 cases of grade 1, grade 2 in 28 cases, 10 cases of grade 3, 5 cases of grade 4, grade 3, grade 4 in study group the proportion was lower than the control group(P<0.05). Conclusion The application of nickel titanium instruments in root canal therapy can not only shorten the time of root canal preparation, but also ensure the effect of root canal filling and relieve the pain. It has high application value and can be popularized and used in clinic.

现如今,根管治疗术,在根尖周病、牙髓病治疗中,得到广泛应用,且疗效显著。根管治疗,主要涉及清理根管系统、成形、三维充填步骤,其中,严密充填以根管预备为基础。根管预备阶段,与治疗耗时、术后疼痛等存在密切联系[1]。2015年7月—2017年8月期间,该院以120例患者为研究对象,分为2组,旨在探讨研究机用镍钛器械在根管治疗中的应用价值及优缺点,现报道如下。
1 资料与方法
1.1 一般资料
方便收集该院收治的120例根管治疗患者,根据治疗方式分为2组,每组60例。对照组29例男性,31例女性,最小18岁,最大53岁,平均(34.5±6.91)岁。研究组男性有27例,女性有33例,最小21岁,最大59岁,平均(35.9±5.68)岁。分析比较2组患者性别及年龄等一般资料,差异无统计学意义(P>0.05),存在可比性。
1.2 纳入及排除标准
1.2.1 纳入标准 ①牙髓炎或根尖周炎等,需接受根管治疗的患者。②年龄为18~60岁,性别不限。③患牙牙根完成发育,没有牙髓治疗史。④术前,经X线检查,结果显示,根管没有特殊弯曲,未出现牙内外吸收、牙析现象。……
