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.

病人和保健人员的感染控制问题正在恶化。病原微生物的消毒灭菌一直是我们非常关注的问题。研究结果如下：1.日本传染病协会于2000年提出了感染控制医生（ICD）的工作说明。2004年在东北大学牙科医院成立了由2名ICD、5名牙医、2名护士、1名药剂师和1名助理官员组成的感染控制小组（ICT）。ICT每个月在医院巡视两次。从那时起，医疗保健服务发生了变化，现在人们认识到，感染控制需要融入临床和公司治理过程。2.硅胶印模由主模具制成。处理组采用高压灭菌器灭菌并浸泡在2%戊二醛中。用浸在2%戊二醛中的印模制成的铸件可用于嵌体的构建。印模经高压灭菌后制成的铸件可用于制作诊断铸件和一些嵌体。3.电解槽中的盐水可电解生成具有杀菌功能的功能水。但随着时间的推移，氯气的排放降低了有效氯的浓度。因此，在本研究中，实验非隔膜型电解装置，研究浓度的变化。将水的pH值调节为9.0，因此水保持高水平的有效氯浓度。4.牙科综合治疗台水中存在大量微生物，增加了牙科患者和工作人员感染的风险。手机和空气/水注射器水管样本范围为1，000至1，000，000 CFU/ml。牙医应该采取最好的方法来保持可接受的水质。
