Infection control of patients with HIV, HBV or HCV in dental care

在病人和保健人员中，感染控制问题正在恶化。我们一直非常关注病原微生物的消毒和灭菌。得到了以下结果：2000年，日本传染病协会提出了感染控制医生（ICD）的工作描述。2004年在东北大学牙科医院成立了感染控制小组，由两名ICD、五名牙医、两名护士、一名药剂师和一名助理警官组成。ICT每月到医院查房两次。从那时起，医疗保健服务发生了变化，现在人们认识到，感染控制需要纳入临床和公司治理流程。硅胶印痕是用主模具制成的。处理组用高压灭菌器灭菌，浸泡在2%戊二醛中。由浸入2%戊二醛的压模制成的铸件可用于镶嵌体的构造。由高压灭菌器灭菌的压模制成的铸件可用于制造诊断铸件和某些镶嵌件。功能水是由电解室中的盐水电解生成的，具有杀菌功能。但随着时间的推移，氯气的排放降低了可用氯的浓度。因此，本研究采用实验非隔膜式电解装置研究其浓度的变化。将水的pH值调整为9.0，从而使水保持较高的有效氯浓度。牙科单位水中大量微生物的存在增加了牙科病人和工作人员感染的风险。机头和空气/水注射器水线标本范围为1,000至1,000,000 CFU/ml。牙医应采取最佳方法，以维持可接受的水质。

The problem of infection control is worsening among patients and health-care personnel. We have been greatly concerned with disinfection and sterilization of pathogenic microbes. The following results were obtained.1.The Japanese Association for Infectious Diseases proposed a job description for an infection control doctor (ICD) in 2000. Infection control team (ICT), which consisted of two ICD, five dentists, two nurses, a pharmacist, and an assistant officer, was established at Tohoku University Dental Hospital in 2004. ICT did the rounds twice a month in the hospital. Since that time there have been changes in healthcare delivery, and it is now recognized that infection control needs to be integrated into clinical and corporate governance processes.2.Silicone impressions were made from a master die. Treatment groups were sterilized by autoclave and immersed in 2% glutaraldehyde. Cast made from impressions immersed in 2% glutaraldehyde are acceptable for use in the construction of inlays. Cast made from impressions sterilized by autoclave can be used for the fabrication of diagnostic casts and some inlays.3.Functional water, which has bactericidal functions, can be electrolytically generated from saline water in electrolysis chamber. But emissions of chlorine gas reduced the available chlorine concentration as time advances. Therefore, in this study, experimental non-diaphragm-type electrolysis apparatuses were made to research changes of the concentration. The water pH was adjusted 9.0, and consequently the water maintained the high level of the available chlorine concentration.4.The presence of large numbers of microorganisms in dental unit water poses an increased risk of infection for dental patient and staff. Handpiece and air/water syringe waterline specimens ranged from 1,000 to 1,000,000 CFU/ml. Dentists should perform the best method for maintaining acceptable water quality.
