摘　　要：目的评价无砷失活剂对急性牙髓炎或慢性牙髓炎的失活效果及术后疼痛缓解程度。方法将212例临床诊断为急性牙髓炎或慢性牙髓炎的磨牙随机分为二组,实验组104例采用无砷失活剂(PD,瑞士产)失活;对照组108例采用金属砷失活剂(本院自制)失活。采用国际通用的VAS直观疼痛标尺法由患者和医师共同评价患者术后疼痛缓解程度及拔髓时的疼痛程度,对量化的结果进行统计学分析。结果无砷失活剂组失活效果满意率为84.5%,略高于金属砷失活剂组的78.7%,χ2检验两组无显著性差异(P>0.05)。无砷失活剂组的临床疼痛有效缓解率为87.5%,略低于金属砷失活剂组的92.6%,统计学比较无明显差异(P>0.05)。结论无砷失活剂对急性牙髓炎或慢性牙髓炎的失活效果和术后疼痛缓解程度与金属砷失活剂无明显差异,牙髓完全摘除是控制牙髓炎性疼痛的最佳方法,条件允许时最好放弃使用失活技术。Objective To evaluate the devitalizing effects and postoperation reaction on acute pulpitis or chronic pulpitis in molars by <PD> devitalizing paste without Arsenic.Methods A total of 212 molars were diagnosed as acute pulpitis or chronic pulpitis,and randomized block designed into two groups.The experimental group: 104 cases were devitalized by <PD> devitalizing paste without Arsenic.The control group: 108 cases were devitalized by Arsenic material.VAS(Vital analogue scale) was adopted to evalu...
