摘要
背景:口腔印模消毒的方法较多,有紫外线消毒法,喷涂、浸泡消毒法,氩等离子流及射频辉光放电对氩气电离消毒法等,目前国内外尚缺乏口腔含漱液含漱后对口腔印模消毒效果的研究。目的:观察含漱西吡氯铵和稳定性二氧化氯含漱液后对所取口腔印模上细菌及真菌的杀灭效果。方法:将100例患者抽签随机分为西吡氯铵含漱液组和稳定性二氧化氯含漱液组,分别做自身对照试验,嘱两组患者先用清水漱口1 min,吐出后用藻酸盐印模材取模,取出模型后用无菌棉拭子采样,放入中和剂中送实验室做细菌及真菌培养。1 h后再分别用各组含漱液漱口1 min,取印模后在印模相同位置用无菌棉拭子采样,同样做细菌及真菌培养,记录含漱前后培养出菌落的个数,观察用含漱液漱口后取模对所取印模上细菌及真菌的杀灭效果。结果与结论:两组含漱前口腔细菌及真菌数量比较差异无显著性意义。两组含漱后取模模型上的细菌及真菌数量均明显低于含漱前(P<0.001)。两组含漱未出现任何不良反应,患者主观感觉含漱后口腔清爽,比较舒适。试验证实取模前用含漱液漱口可有效减少藻酸盐印模上细菌及真菌的数量,有效防止医生和患者之间的交叉感染。
BACKGROUND：There are many methods for dental impression disinfection, including ultraviolet disinfection method, spraying, immerses disinfection method, argon plasma jet and radio frequency glow discharge on the argon gas ionization disinfection method. At present, there is stil lack of studies addressing the disinfection effect after gargling with mouthwash.
OBJECTIVE：To detect the kil ing effect on bacteria and fungi from the dental impressions, which are taken after gargling with cetylpyridinium chloride gargle and stable chlorine dioxide gargle, respectively.
METHODS：One hundred patients were randomly divided into cetylpyridinium chloride gargle group and stable chlorine dioxide gargle group. They were told to gargle with clean water for 1 minute, and then impressions were taken to remove the models with sterile cotton swab sampling in neutralizing agent which were sent to laboratory for bacteria and fungi culture. After 1 hour, the patients were asked to gargle with the different mouthwashes for 1 minute again, and then sterile cotton swab sampling was done at the same position for bacteria and fungi culture. The number of colonies was recorded, and the kil ing effects on kil ing bacteria and fungi on the surface of the impressions before and after gargling with different mouthwashes were observed.
RESULTS AND CONCLUSION：The number of bacteria and fungi before gargal had no significance difference before gargling. After gargling, the number of bacteria and fungi on the model was significantly lower than before （P〈0.001）. Two groups did not appear with any adverse reactions, and patients felt refreshed and comfortable after gargling with mouthwash. To gargle with mouthwash before taking impressions can control the number of bacteria and fungi on the samples effectively, thereby achieving the aim of control ing the mutual infections between the doctor and the patients effectively.
