目的评价Antipulp牙髓失活剂的临床失活效果。方法选择2006年1月至2008年1月沈阳市妇幼保健所收治的后牙需行牙髓失活治疗的急、慢性牙髓炎患者115例(120颗患牙),随机分为试验组和对照组,各60颗。试验组开髓后封Antipulp牙髓失活剂14d,对照组开髓后封亚砷酸糊剂48h。观察并比较两组患牙在失活过程中疼痛及失活效果。结果试验组失活有效率和中、重度疼痛发生率为91.67%和10.00%,对照组为75.00%和26.67%,组间差异均有统计学意义(P<0.05)。结论 Antipulp牙髓失活剂可明显减少牙髓炎患者在失活及拔髓过程中的疼痛,且效果优于亚砷酸糊剂。
Objective To evaluate the clinical inactivation effect of Antipulp dental pulp inactivator. Methods A total of 115 patients (120 teeth) with acute and chronic pulpitis who underwent dental pulp inactivation of the posterior teeth admitted to Shenyang MCH from January 2006 to January 2008 were randomly divided into experimental group and control group Group, each 60. The experimental group was treated with Antipulp dental pulp inactivation agent for 14 days after opening the pulp, and the control group was opened and sealed with arsenic acid paste for 48 hours. Observe and compare the pain and inactivation effect of the two groups of teeth during inactivation. Results The effective rate of inactivation and the incidence of moderate and severe pain were 91.67% and 10.00% in the experimental group and 75.00% and 26.67% in the control group, respectively. There was significant difference between the two groups (P <0.05). Conclusion Antipulp dental pulp inactivator can significantly reduce the pain of patients with pulpitis during inactivation and cord retraction, and the effect is better than arsenious acid paste.
