Objective: The aim of the present study is to evaluate dental healthcare workers' knowledge, attitudes, and practices toward hepatitis B infection.
Materials and methods: This study was a cross-sectional self-administered, structured questionnaire survey that was conducted in Khartoum/Sudan. The questionnaire was completed by 177 dental healthcare providers who practice in public dental clinics in Khartoum state. The completion rate was 100%.
Results: The study participants showed relatively acceptable knowledge of hepatitis B virus (HBV) infection. The majority (98.3%) were familiar with hepatitis B infection. About 93% answered correctly that blood, blood products, and needles/sharps are the route of transmission of HBV. About 65.5% completed HBV vaccination. About 59.3% had a history of needle sticks and only 16% reported their injury. Dentists and nurses almost had the same knowledge, but dentists were slightly having better knowledge in some aspects. Statistical Package for Social Sciences (SPSS) version 20 was used. Chi-square test was used to determine the relationship between categorical variables.
Conclusion: Most of the study participants were aware of HBV infection, routes of transmission, prevention, and necessity of vaccination, but they are deficient in some areas, like needle-stick injury protocol and post-exposure prophylaxis (PEP). The study revealed a low level of HBV vaccination coverage rate. Further strategies for preventing workplace exposure, training programs on HBV infection, including PEP, and increasing the vaccination coverage rate of all healthcare workers are highly recommended.
Clinical significance: Dental healthcare workers are at high risk of acquiring hepatitis B infection. The majority of exposure in dentistry is preventable. Understanding the knowledge and awareness of dental health toward hepatitis B is crucial to design and apply preventive measures to control transmission and potential complications.
