Abstract: Objective To evaluate the effect of two different root canal therapy on postoperative pain of root canal preparation. Methods Patients need to do root canal treatment of 118 cases were randomly divided into two groups: group A (59), root canal working length of apical stop point located in the root tester instructions arc baseline on the highest point (Beep 35 times / min); group B (59), root canal working length of apical stop point located in the root tester instructions arc baseline nadir (Beep 65 times/min), pain visual simulation score (visual analogue scale, VAS) scores recorded root of two groups of patients with preoperative preparation and after 12 h, 1 d, 2 d, 3 d, 1 week pain situation tube. Results In 118 cases, the total incidence rate of tooth pain was 18.6%, the A group was 16.9%(10/59), and the B group was 20.3% (12/59), and there was no significant difference between 2 groups (P>0.05 ). VAS of two groups had no statistical significance (P>0.05 ). Conclusion There was no significant difference for postoperative pain of the two kinds of apical stop preparations.

摘要: 目的 评价根管预备中2种不同根管预备终止点对术后疼痛的影响。方法 需做根管治疗的患者118例用Endo Pilot根测仪进行根尖定位,随机分成2组:A组(59例),根管预备终止点位于根测仪指示“弧形基线”上最高点(蜂鸣声35次/min);B组(59例),根管预备终止点位于根测仪指示“弧形基线”下最低点(蜂鸣声65次/min)。用疼痛视觉模拟评分法(visual analogue scale,VAS)的分值,记录2组患者根管预备前和术后12 h、1 d、2 d、3 d、1周疼痛情况。结果 118颗患牙疼痛的总发生率为18.6%,其中A组为16.9%(10/59),B组为20.3%(12/59),2组疼痛发生情况差异无统计学意义(P>0.05);A、B 2组在各时间段VAS疼痛分值差异无统计学意义(P>0.05)。结论 根管预备中2种根管预备终止点对术后疼痛无明显影响。
