Abstract

Objectives: Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infections are known to pose a major threat for dental health workers (DHWs). Previously, we reported that the HBV and HCV infection rates among DHWs in the Oita Prefecture in Japan were higher than those among the general population. The aim of this study was to disseminate knowledge about hepatitis and its prevention among the DHWs.

Materials and methods: Educational booklets were mailed to 2,197 DHWs working in 487 dental clinics. After anonymously responding to online questions about their experience with HBV and HCV testing, Hepatitis B vaccination, and percutaneous injury, the subjects were required to respond to additional questions about their understanding of hepatitis.

Results: A total of 521 DHWs (205 males and 316 females) responded to the questionnaires. Among them, 61.6% had experienced percutaneous injuries, but only 19.4% were fully aware of how to deal with them before reading the booklet, and also 10.6% had sufficient knowledge about hepatitis. The past Hepatitis B vaccination, past HBV testing rate, and past HCV testing rate were 62.4%, 71.8%, and 43.2%, respectively. The DHWs who are not dentists (n = 293) had significantly lower rates of past testing for their own hepatitis virus, knowledge about treatment of percutaneous injuries, and awareness of hepatitis as compared to dentists (n = 228). After reading the booklet, 99.5% of subjects found the booklet useful and 87.3% said it would influence their future hepatitis testing.

Conclusion: The educational booklet was effective way to increase DHWs' knowledge about Hepatitis B and C and how to manage percutaneous injuries.

Keywords: dental healthcare workers; dentist; hepatitis b vaccine; hepatitis b virus; hepatitis c virus; questionnaire.
