220例牙髓病或根尖周患者根管治疗的根管预备和充填质量分析

Analysis of root canal preparation and filling quality in 220 patients with endodontic disease or apical periodontitis

目的:探讨牙髓病或根尖周患者根管治疗的根管预备和充填质量。方法:按照随机数字表法,将220例牙髓病及根尖周患者分为对照组(n=110)和研究组(n=110)。对照组患者予以手持不锈钢K锉进行根管预备,研究组患者予以Protaper机械镍钛锉进行根管预备。观察两组患者临床疗效、术后充填质量及疼痛程度。结果:术后,研究组的临床疗效(94.55%)高于对照组(80.91%),差异有统计学意义(P<0.05);研究组患者的恰填率(92.73%)高于对照组(76.36%),差异有统计学意义(P<0.05);研究组患者疼痛反应率(3.64%)低于对照组(10.91%),差异有统计学意义(P<0.05)。结论:牙髓病或根尖周患者根管治疗中予以Protaper机械镍钛锉进行根管预备效果满意,有效提高临床疗效和充填质量,降低患者术后疼痛反应率,操作简便且安全高效。

Objective:To investigate root canal preparation and filling quality in patients with endodontic disease or apical periodontitis.Methods:A total of 220 cases patients with endodontic disease and apical periodontitis were divided into the control group(n=110)and the study group(n=110)according to the random number table method.Patients in the control group were given a stainless steel K file for root canal preparation,and patients in the study group were treated with protapermechanical nickel-titanium for root canal preparation.The clinical efficacy,postoperative filling quality and pain level of the two groups were observed.Results:The clinical efficacy(94.55%)of the study group was significantly higher than that of the control group(80.91%),and the difference was statistically significant(P<0.05).The rate of postoperative filling(92.73%)in the study group was significantly higher than that in the control group(76.36%),and the difference was statistically significant(P<0.05).The pain response rate(3.64%)of the study group was significantly lower than that of the control group(10.91%),the difference was statistically significant(P<0.05).Conclusion:Protaper mechanical nickel-titanium for root canal preparation is satisfactory in endodontic or apical periodontal root canal therapy,which can effectively improve clinical efficacy and filling quality,and reduce postoperative pain response rate,and it is easy to operate,safe and efficient.
