In developing countries such as Egypt, the risk of blood-borne diseases such as human immunodeficiency virus, hepatitis B virus, and hepatitis C virus is high for healthcare workers. To evaluate infection control knowledge, attitudes and practices, as well as the associated risk of percutaneous infection among dental students, a cross-sectional study was conducted in four Egyptian public dental schools in 2016. A total of 1776 students received an anonymous questionnaire on infection control knowledge, attitudes, and practices and the occurrence of needle and sharps injuries; 1067 (60.1%) completed the questionnaire. Third- (pre-clinical), fourth- (junior-clinical), and fifth-year (senior-clinical) students comprised 44.2%, 15.6%, and 40.2%, respectively. Although the majority of the students reported good attitudes and practices for infection control, knowledge scores were generally low. Female students scored higher on self-protection and sterilization practices than did male students, and the fourth-year students showed significantly higher scores for infection control practice than did the fifth-year students. In multivariate analysis, higher scores for all infection control practices were associated with higher scores for attitudes towards infection control and fewer (1-3) needle injury experiences. Although an alarming proportion had experienced needle or sharps injuries during clinical training, around 30% of the students had not received a complete hepatitis B vaccination. Future infection control education should introduce refresher training before graduation that focuses on injury prevention and post-exposure protocols. Additionally, introducing safer products and clinical procedures is highly recommended to minimize the risk of injuries during clinical practice for dental students in Egypt.
