In dentistry, as in surgery, there is a risk of cross-infection for both patients and staff The aim of this research was to evaluate procedures and behaviors enacted by dental staff which might engender a risk for themselves and their patients.
A questionnaire was administered to 106 dental workers in Genoa (Italy), both public and private. Whenever personal interviews were conducted, the facilities involved were also inspected and the activities of the dental staff were observed directly.
This research highlighted some critical points in both structural and organizational features and in the management of infective hazards in the sample considered. In some cases, inadequacies were noted with regard to the prevention of cross-infections, such as the lack of disinfection of work surfaces and the handles of chair-set accessories.
The particular nature of dental work, in which aerosols of blood and saliva may be produced by rotating instruments, engenders a risk of infection. Application of the various preventive measures available can significantly reduce microbial contamination and the risk of occupational infection and cross-infections. Furthermore, improvement in the structural and organizational features of dental surgeries and the continuing education of health-care workers is indispensable to the control and prevention of infectious diseases.
在牙科领域，如同外科手术一样，患者和工作人员都面临交叉感染的风险。本研究的目的是评估牙科工作人员的操作程序和行为，这些操作程序和行为可能给他们自己以及患者带来风险。
对意大利热那亚的106名牙科工作人员（包括公立和私立机构的）进行了问卷调查。每当进行个人访谈时，还会对相关设施进行检查，并直接观察牙科工作人员的活动。
本研究突出了所研究样本在结构和组织特征以及感染危害管理方面的一些关键点。在某些情况下，发现了预防交叉感染方面的不足之处，例如工作表面和椅旁附件把手缺乏消毒。
牙科工作的特殊性质，即旋转器械可能产生血液和唾液气溶胶，会带来感染风险。应用现有的各种预防措施可显著减少微生物污染以及职业感染和交叉感染的风险。此外，改善牙科手术室的结构和组织特征以及医护人员的继续教育对于控制和预防传染病是必不可少的。
