两种消毒剂在牙科设施表面消毒效果的比较

目的比较过硫酸氢钾复合盐与含氯消毒剂对牙科设施表面的消毒效果。方法采用随机数字表法将24台牙科治疗椅痰盂分为实验组和对照组各12台。实验组采用过硫酸氢钾复合盐（RelyOn^TM Virkon消毒剂）擦拭消毒,对照组采用含氯消毒剂（“84”消毒液）擦拭消毒。消毒前和消毒后10min分别进行采样,比较两种消毒液的杀菌率。结果硫酸氢钾复合盐与含氯消毒剂的平均杀菌率均大于98％,两者比较差异无统计学意义（Z=-0．347,P〉0．05）。结论硫酸氢钾复合盐与含氯消毒剂消毒效果相当,并且其安全性、易用性和环保性更具有优势,方便在患者密集繁杂的口腔门诊中使用。

Effect of different disinfectants on the surface of dental facilities

Objective To compare the effect of Potassium peroxymonosulfate and disinfectant containing chlorinedisinfecting on the dental facilities surface. Methods The table of random number was used and twenty-four spittoons of dentistry cures chairs were divided into experimental group and control group. The Potassium peroxymonosulfate （RelyOnTM Virkon disinfectant ） was used to disinfect the spittoons in the experimental and the disinfectant containing （ chlorine ＂84＂ disinfectant ） was used in the control group. The samples were collected at 10 minutes before and after disinfection respectively, and the the ratio of disinfection were observed. Results The mean ratio of disinfection of Virkon and ＂84＂ disinfectant was more than 98% , there were no statisticant differences between two groups （ Z = - 0. 347, P 〉 0. 05）. Conclusions The effects of disinfection are similar between Virkon and ＂84＂disinfectant,and Virkon disinfectant is conveniently used in the crowded dental out-patient department for its better security, usability and environment protection.
