牙周洁治术中洗必泰漱口降低气雾污染的临床研究

目的 探讨如何降低牙周洁治术中汽雾污染,并做好医护人员职业防护.方法 选取无口腔及上呼吸道感染、无慢性疾病、无传染病及其他禁忌症的患者30例,随机分为实验组和对照组.实验组患者在牙周洁治术中采用洗必泰漱口,对照组患者采用传统的清水漱口.2组患者分别在洁治术前、术后进行口腔细菌采样;术前、术中10 min、20 min、30 min和手术结束5个时段进行空气采样做细菌培养,并对结果进行分析.结果 实验组患者牙周洁治中空气采样、洁治后口腔采样细菌培养结果远远低于对照组,P<0.01,差异有统计学意义.结论 洗必泰消毒作用好、性质稳定,可广泛用于皮肤黏膜消毒.在牙周洁治过程中采用洗必泰漱口,可随时清除洁治术中口腔内和汽雾中的细菌和微生物,从而达到降低环境污染、加强口腔科医护人员职业防护的目的 .

Clinical research in effect of chlorhexidine to reduce steam contamination in periodontal scaling

Objective This research attempted at prevention of steam contamination and protection of medical staff in periodontal scaling. Methods Thirty sample patients without oral cavity or upper res-piratory tract infection, chronic disease, infectious disease or other contraindication were randomly classified into the experimental group and the control group.The former gargled with chlorhexidine in the process of periodontal scaling while the latter rinsing only. Oral cavity bacteria of both groups were sampled before and after operation;air samples were got at five periods of time(before operation, 10 minutes in operation, 20 minutes in operation, 30 minutes in operation, and end of operation) and germicnltured.The entire data were analyzed.Results Air samphng in periodental scaling and oral sample germiculture after the scaling in the experimental group were lower than those of the control group, P<0.01. Conclusions With effective disinfection and sta-ble characteristics, chlorbexidine can be popularly utilized in skin mucous membrane disinfection. Gargling with chlorhexidine in periodontal scaling eliminates bacteria and microorganism in oral cavity and resulting steam,thus reducing environmental pollution and protecting the health of medical staff.
