开髓后行开放引流术与封闭治疗对急性牙髓炎的疼痛缓解效果对比

Comparison of the pain relief effects of two emergency methods in acute pulpitis

目的对比分析开髓后行开放引流术与封闭治疗对急性牙髓炎的疼痛缓解效果。方法 144例(共201颗患牙)急性牙髓炎患者分为实验组和对照组,对照组患者开髓后行开放引流术,实验组患者开髓后封入失活剂,观察患者治疗24 h后自发性疼痛情况、7 d后患牙叩痛情况及并发症情况。结果实验组治疗24 h、7 d后镇痛有效率(88.9%,87.5%)均明显高于对照组(69.4%,58.3%),两组差异具有统计学意义(P<0.05);对照组患者治疗7 d后出现明显疼痛的患者(Ⅱ级以上)30例(42.7%),与治疗24 h比较呈上升趋势,镇痛有效率下降,实验组治疗7 d与24 h比较差异无统计学意义(P>0.05)。结论开髓后封入失活剂在缓解自发性疼痛(治疗后24 h)和叩痛(治疗后7d)方面明显优于开髓后行引流术,且无明显并发症发生,安全有效。

Objective Comparative analysis of the pain relief effects of open drainage and closed treatment in acute pulpitis. Methods 144 patients （201 teeth） with acute pulpitis were divided into experimental group and con- trol group. The patients in control group were provided with open drainage, and the patients in experimental group were treated with pulp inactivating agent. Spontaneous pain at 24 h after treatment and concurrent percussion pain at 7 d after treatment were observed in both groups. Results The analgesia efficiencies at 24 h or 7 d after treatment in the experimental group were significantly higher than those in the control group （88.9% vs 69.4% and 87.5% vs. 58.3%, respectively, P〈0.05）. At 7d after treatment, in the control group, the number of patients with obvious pain （stage Ⅱ ） was 30 cases （42.7%）, which is higher than that at 24 h, and the analgesia efficiency decreased with no sig- nificant difference （P〉0.05）. Conclusion The pulp inactivating agent was safe and effective with no obvious compli- cations, which was significantly better than open drainage in alleviating spontaneous pain （24 h after treatment） and percussion pain （7 d after treatment）.
