摘　　要：目的:探讨无砷牙髓失活剂Depulpin和三氧化二砷用于牙髓失活的临床效果。方法:将768例恒牙深龋所致的急性牙髓炎的患者随机均分为2组:试验组384例,对照组384例。其中120例为颈部近龈缘深龋所致急性牙髓炎患者,也随机均分为2组:试验组60列,对照组60例。各例临床检查均为深龋,探痛明显并有轻微叩痛。试验组患者用Depulpin,对照组用三氧化二砷。对失活效果进行量化分类,量化结果进行统计分析。结果:Depulpin的失活有效率为93.7%,三氧化二砷的有效率为92.3%。对近龈缘颈部深龋因失活治疗并发的牙周损伤:试验组为0例,对照组为5例。结论:Depulpin作为一种新型无砷失活剂,失活作用明显,与临床传统用的三氧化二砷相比,对牙周无创伤作用,失活效果优于三氧化二砷。Objective：To study the devitalizing effects on pulpitis by Depulpin devitalizing paste.Methods：A total of 768 permanent tooth were diagnosed as acute pulpitis because of serious detal carvies and randomied block designed into two groups. The study group 384 cases were divitalized by Depulpin devitalizing paste,include 60 cases detal neck carves.The control group 384 cases were devitalized by As_2O_3 devitalizing paste induding 60 cases detal neck carves.The data was analyzed with spss10.0 software package.Results：The rate of devitalizing effect of study group was 93.7%,the control group was 92.3%,Depulpin do no harm to periodontal in detal neck caves.But there were 5 cases peridental gums harmed in control group.Conclusions： The effect of devitalizing on Depulpin is preceded to As_2O_3 and do no harm to gums.
