目的:探讨一次法根管治疗牙髓炎的术后急症发生率以及影响因素。方法:随机将2014年5月至2015年5月入选的80例牙髓炎患者分为A1组(K锉一次法根管治疗)、A2组(K锉多次法根管治疗)、B1组(手用Pro Taper一次法根管治疗)、B2组(手用Pro Taper多次法根管治疗),各20例。比较各组术后急症发生率,并对影响因素进行回归性分析。结果:A1组和B1组疼痛发生率的差异比较、A2组和B2组疼痛发生率的比较,差异具有统计学意义(P<0.05)。A1与A2组患者疼痛发生率和B1与B2组患者疼痛发生率的比较,差异均无统计学意义(P>0.05)。Logistic回归性分析结果显示影响急症发生的因素包括根管治疗次数和填充结果。结论:牙髓炎患者采用手用Pro Taper一次法根管进行治疗,术后急症发生率有效降低;同时应注意根管治疗次数和填充结果等影响因素,确保患者治疗效果的提升,并避免术后急症的发生。
Objective: To investigate the incidence and influencing factors of acute postoperative acute pulpitis treated with root canal therapy. Methods: A total of 80 patients with pulpitis who were selected from May 2014 to May 2015 were randomly divided into group A1 (K-file one-time root canal therapy), A2 group (K-file multiple root canal therapy), group B1 (A hand Pro Taper root canal treatment), B2 group (hand Pro Taper multiple root canal treatment), each 20 cases. The incidence of acute postoperative complications in each group was compared and the influencing factors were analyzed retrospectively. Results: The difference in the incidence of pain between groups A1 and B1 was statistically significant (P <0.05). The difference between groups A2 and B2 was statistically significant (P <0.05). There was no significant difference in the incidence of pain between A1 and A2 patients and between B1 and B2 patients (P> 0.05). Logistic regression analysis showed that the factors that affected the emergency were root canal treatment times and filling results. CONCLUSIONS: Pulpitis patients are treated with Pro Taper primary root canal by hand, and the incidence of postoperative emergency is effectively reduced. At the same time, the factors such as the number of root canal treatments and filling results should be paid attention to to ensure the therapeutic effect of patients and to avoid the operation After the emergency occurred.
