Objective: A survey was conducted of 206 students in dental hygiene departments in some areas who experienced clinical practice to find out their knowledge and performance of infection prevention.
Methods: The general characteristics of those surveyed, the experience of stabbing the instrument during practice, knowledge of infection prevention, and practices were self-populated, and statistical analysis of the data was conducted using the IBM SPSS Statistics program.
Results: Out of 89 students (43.20%) who had been stabbed by a device during clinical practice, 40 (44.94%) were found to be the highest when cleaning the instrument after treatment, and 36 (40.45%) especially when cleaning the explorer. Wearing a mask at all times was the highest for dental care at 76.21% (p < 0.05), and 63.59% for school experience in prevention of infection (p < 0.05). The highest rates were 72.33% for washing hands after treatment, 72.81% for wearing new gloves every time a patient changed, and 73.79% for always wearing gloves when cleaning a device, but it has no significance.
Conclusion: Recognizing the importance of education in dental hygiene and infection management of students, further development of programs that can improve the performance of wearing personal protective gear and preventing infection in clinical practice is deemed necessary.
