“…A previous study has suggested that eye protection plays a role in the reduction of virus infection ( 25 ). Nevertheless, used dental goggles without effective and timely disinfection may become potential reservoirs for pathogens ( 30 ). Therefore, in order to protect the eyes from the hazards of aerosols and particulate matter generated in dental procedures, dental professionals are required to wear goggles or face shields and replace them in time when they are contaminated by blood, body fluids, secretions, etc.…”

BackgroundAppropriate use of personal protective equipment (PPE) could significantly reduce the risk of viral transmission and infection. This study aimed to assess the use of PPE among dentists during the COVID-19 pandemic in China, explore its influencing factors, and provide some practical recommendations.MethodsAn online cross-sectional survey was conducted among 384 Chinese dentists in September 2022. The questionnaire comprised a series of questions about demographic characteristics, compliance with proper PPE use, personal barriers to use, and exposure risk estimation.ResultsOf the 384 respondents, 57.3% had unacceptable compliance with the proper use of PPE during COVID-19. Medical surgical mask is the most common for dental professionals to wear (93.8%), followed by goggles or face shield (63.8%), and isolation gown (53.1%). Unexpectedly, only 63.3% of respondents always change masks with guidelines. The condition for changing goggles/face shields and isolation gowns is even worse (45.6 and 37.0%, respectively). Visual barriers, physical discomfort, complex procedures, and heavy workload were the most common personal barriers to use. According to the results of Chi-square test and correlation analysis, PPE use compliance was associated with age, years of practice, medical institution type, and exposure risk estimation.ConclusionChinese dental professionals need to improve their compliance with the proper use of PPE, especially those in the 31–40 age group, with 11–15 experience years and working in private dental clinics. Increasing compliance with PPE may be achieved by addressing personal barriers to use, human resource shortages, and perceptions of exposure risk.

“…Microorganisms on a fomite, which may remain viable for days or months, could be transmitted among patients and hospital personnel [3]. Several studies have demonstrated the bacterial contamination of non-critical medical devices (NCMDs), such as otoscopes, white coats, pens, goggles, and other surfaces [3], [4], [5], [6], [7], [8]. In China, the flashlight is a basic NCMD for healthcare workers.…”

Aim This study aims to assess the infection risks of flashlight contamination in a stomatology hospital and compare the disinfection effectiveness of alcohol (75%) and disinfecting wipes. Background The flashlight is a basic non-critical medical device in oral and maxillofacial surgery wards. Wounds are mostly found in oral cavities; therefore, reusable flashlights may be a potential source of nosocomial infections (NIs). However, the microbial flora present in flashlights used in hospitals has not yet been explored. Methods This study investigated the microbial contamination of 41 flashlights used in a stomatology hospital in Guangzhou in March 2016. Results Results indicated that 75.6%(31/41) of the flashlights had microbial contamination. Gram-positive bacteria accounted for 72.7%(24/33)of the microbial groups contaminating the flashlights, and Gram-negative bacteria (21.2%, 7/33), and fungi (6.1%, 2/33) constituted the remaining contaminants. The predominantly isolated species was Staphyloccus (66.7%, 22/33), especially Staphylococcus aureus (24.2%, 8/33). Approximately 77.3% (17/22) of the types of bacteria detected in the hands were same as those in the corresponding flashlights. Both the bacterial overstandard and S. aureus detection rates of doctors' flashlights were higher than those of nurses' flashlights (16/17 vs. 14/23, 7/17 vs. 1/23, respectively) ( P < 0.05). Moreover, both disinfectants performed excellently, and their eligibility rates were not significantly different (17/17 vs. 14/14) ( P > 0.05). Conclusion Flashlights are potential causes of NIs. Disinfecting flashlights could be an effective and practical infection control method.
