Among health care professionals, dentists are more prone to infection due to their direct contact with blood and saliva. This study highlights the level of compliance with infection control measures among dental students; and linked this to their knowledge and attitudes regarding infection control measures and proper vaccinations. The study is a multi-centre analytical cross-sectional survey. The sample size was 969 clinical years' students from governmental and private dental colleges in Sudan and Saudi Arabia. A pre-coded, pre-tested, and anonymous questionnaire consisted of seven categories of knowledge, attitude, awareness, and practices, including 40 questions, was answered. The study has linked knowledge, attitude, and practice in dental clinics with possible COVID-19 transmission in dental clinics. The results showed that the use of some Personal Protective Equipment was low in Sudan and moderate in Saudi Arabia (statistically significant, p < 0.001). Moderate percentage of Hepatitis B vaccination status, with low percentage of Post HBV serology, was reported (p < 0.001). The percentages of major causes of percutaneous and/or eye exposure/injury, for examples, were as follows: anesthesia (33.3-62.7%, p 0.006) and suture needle (17.5-39.4%, p 0.037). In conclusion, dental students in the present study had good knowledge and positive attitudes regarding infection control in general, but showed moderate compliance with the recommended infection control guidelines.
