目的探讨一次性根管治疗慢性根尖周炎疗效。方法 96例慢性根尖周炎按照随机抛硬币法分组为对照组与观察组各48例。通过采用视觉模拟法(VAS)评价治疗前、后疼痛情况,并统计根尖周治愈情况。结果治疗后,两组VAS评分较治疗前显著下降,然观察组下降较对照组显著,P<0.05;观察组治疗有效率为97.92%(47/48)略低于对照组100.00%(48/48),P>0.05。结论一次性根管治疗可显著减轻患者疼痛,易被患者所接受。
Objective To investigate the curative effect of disposable root canal therapy on chronic apical periodontitis. Methods 96 cases of chronic apical periodontitis were randomly divided into the control group and the observation group according to the random coin method in 48 cases. Visual acuity (VAS) was used to evaluate the pain before and after treatment, and the healing of periapical period was statistically analyzed. Results After treatment, VAS score decreased significantly in both groups, however, the decrease in observation group was more significant than that in control group (P <0.05); the effective rate in observation group was 97.92% (47/48), slightly lower than that in control group (100.00%, 48 / 48), P> 0.05. Conclusion One-time root canal therapy can significantly reduce the patient’s pain, easily accepted by the patients.
