The risk of cross-infection in dental clinics and laboratories has attracted the attention of practitioners for the past few years, yet several medical centers have discarded compliance with infection control guidelines, resulting in a non-safe environment for research and medical care. In Jordan, there is lack of known standard infection control programs that are conducted by the Jordanian Dental Technology Association and routinely practiced in commercial dental laboratories. The aim of this study was to examine the knowledge and practices in infection control among dental technicians working in commercial dental laboratories in Jordan. Data were collected from the dental technicians by a mailed questionnaire developed by the author. The questionnaire asked respondents to provide demographic data about age and gender and to answer questions about their knowledge and practice of infection control measures: use of gloves, use of protective eyeglasses and face shields, hepatitis B virus (HBV) vaccination, laboratory work disinfection when sent to or received from dental offices. and regularly changing pot water or pumice slurry. Of the total respondents, 135 were males (67.5 percent) and sixty-five were females (32.5 percent) with a mean age of twenty-seven years. The results showed that 24 percent of laboratory technicians wore gloves when receiving dental impressions, while 16 percent continued to wear them while working. Eyeglasses and protective face shields were regularly worn by 35 percent (70/200) and 40 percent (80/200) of technicians, respectively. Fourteen (14 percent) had received an HBV vaccination, and 17 percent inquired if any disinfection measures were taken in the clinic. Eighty-six percent of the technicians reported that pumice slurry and curing bath water were rarely changed. Only five dental technicians (two males and three females) were considered to be fully compliant with the inventory of infection control measures, a compliance rate of 2.5 percent with no significant difference between males and females (p>0.05). In conclusion, there is lack of compliance with infection control procedures of dental technicians working in commercial laboratories in Jordan.
在过去几年中,牙科诊所和实验室的交叉感染风险引起了从业者的关注,但仍有一些医疗中心未遵守感染控制指南,导致研究和医疗护理环境不安全。在约旦,约旦牙科技术协会并未实施已知的标准感染控制计划,商业牙科实验室也未常规执行这些计划。本研究的目的是调查约旦商业牙科实验室中牙科技术人员的感染控制知识和实践情况。作者通过邮寄问卷从牙科技术人员那里收集数据。问卷要求受访者提供年龄和性别的人口统计学数据,并回答有关他们对感染控制措施的知识和实践的问题:手套的使用、防护眼镜和面罩的使用、乙型肝炎病毒(HBV)疫苗接种、送往或从牙科诊所接收时实验室工作的消毒,以及定期更换罐水或浮石糊剂。在所有受访者中,135人为男性(67.5%),65人为女性(32.5%),平均年龄为27岁。结果显示,24%的实验室技术人员在接收牙齿印模时戴手套,而16%的人在工作时仍继续戴手套。分别有35%(70/200)和40%(80/200)的技术人员经常佩戴眼镜和防护面罩。14人(14%)接种了HBV疫苗,17%的人询问诊所是否采取了任何消毒措施。86%的技术人员报告说浮石糊剂和固化浴水很少更换。只有五名牙科技术人员(两名男性和三名女性)被认为完全符合感染控制措施清单,合规率为2.5%,男女之间无显著差异(p>0.05)。总之,约旦商业实验室中的牙科技术人员缺乏对感染控制程序的遵守情况。
