Abstract

Background
Dental hygienists are crucial in managing infection control within dental clinical settings. This study focused on examining the pre-treatment infection control practices (PT-PRF_IC) of Korean dental hygienists in the context of coronavirus disease (COVID-19) and identifying factors influencing their implementation levels.
Methods
An online, self-administered survey was conducted with 263 dental hygienists working in dental hospitals or clinics. The survey explored various aspects such as the experience with infection control education (Edu _IC), PT-PRF IC, and the types of surface disinfectants used. Additionally, data from previous studies on the knowledge level of COVID-19 (KNW_CO), infection control awareness level (AWR_IC), infection control performance level (PRF_IC), and infection control organizational factor (OFW_IC) were utilized. Statistical analyses included t-tests, one-way ANOVA, chi-square tests, Pearson correlation, and multiple linear regression.
Results
The study identified variations in PT-PRF IC based on the number of dental hygienists within an organization. Differences in Edu IC were observed concerning age, number of years worked, and monthly pay. The OFW IC had the most substantial impact on PT-PRF IC, followed by PRF IC, and AWR_IC.
Conclusion
To improve compliance with PT-PRF IC, it is essential to consider a combination of factors including OFW IC, PRF IC, and AWR_IC. Strengthening organizational factors and awareness can enhance infection control practices and prevent COVID-19 transmission during dental care.
