目的研究并探讨一次性根管治疗在隐裂性牙髓炎中的临床价值。方法 100例隐裂性牙髓炎患者作为研究对象,采取计算机随机序列分组法分为对照组及观察组,各50例。对照组患者实施传统多次根管治疗,观察组患者实施一次性根管治疗。比较两组患者的临床疗效、牙周菌斑指数、牙龈出血指数、疼痛评分、随访1年治疗成功率。结果观察组患者的临床总有效率为94%,高于对照组的78%,差异具有统计学意义(P<0.05)。观察组患者的术后牙周菌斑指数、牙龈出血指数、疼痛评分均低于对照组,差异均具有统计学意义(t=6.246、5.112、5.868,P<0.05)。随访1年,观察组患者的治疗成功率为90%,高于对照组的74%,差异具有统计学意义(P<0.05)。结论采取一次性根管治疗法对隐裂性牙髓炎患者进行治疗的近期疗效显著,可有效减轻疼痛及牙龈出血情况,且具有显著的远期疗效,可在隐裂性牙髓炎的临床治疗中推广应用。
Objective To study and discuss the clinical value of disposable root canal therapy in the treatment of cryptogenic pulpitis. Methods One hundred cases of patients with cryptogenic pulpitis were divided into control group and observation group by computer randomized sequential grouping method, 50 cases each. Patients in the control group were treated with traditional root canal therapy, while those in observation group were treated with one-time root canal therapy. The clinical efficacy, periodontal plaque index, gingival bleeding index, pain score and success rate of 1-year follow-up were compared between the two groups. Results The total clinical effective rate in the observation group was 94%, which was higher than that in the control group (78%), the difference was statistically significant (P <0.05). The postoperative periodontal plaque index, gingival bleeding index and pain score in the observation group were lower than those in the control group, the differences were statistically significant (t = 6.246,5.112,5.868, P <0.05). The follow-up of 1 year, the observation group patients treatment success rate was 90%, higher than 74% of the control group, the difference was statistically significant (P <0.05). Conclusion One-time root canal therapy for patients with cryptogenic pulpitis has a significant short-term curative effect, which can effectively relieve the pain and gingival bleeding and has significant long-term curative effect. It can be used in clinical treatment of cryptogenic pulpitis Treatment of the promotion and application.
