Hepatitis B and C infections among Japanese dental health workers: Insights from vaccination rates and screening results in the Oita prefecture
Objective
This study examined the hepatitis B virus (HBV) and hepatitis C virus (HCV) infection rates and vaccination rates for hepatitis B (HB) among dental healthcare workers (DHCWs) in the Oita prefecture, Japan.
Methods
Hepatitis virus testing was conducted on 1920 participants (486 dentists and 1434 dental staff). Anonymous data on age, gender, occupation, hepatitis B surface antigen (HBsAg), antibodies to hepatitis B surface antigen (anti-HBs), antibodies to HCV (anti-HCV), history of HB vaccination, and antiviral treatment for individuals with positive anti-HCV were collected.
Results
The positivity rates for HBsAg, anti-HBs, and anti-HCV were 0.5%, 39.7%, and 0.6%, respectively. Dentists had significantly higher rates of anti-HBs positivity (53.9% vs. 34.9%; p < .0001) and anti-HCV positivity (1.4% vs. 0.3%; p = .0080) compared to dental staff. The vaccination and non-vaccination rates among 1395 with a known HB vaccination history were 59.1% and 40.9%, respectively. Dentists had a significantly higher HB vaccine vaccination rate than the dental staff (73.6% vs. 54.0%; p < .0001). Those in the vaccination group were younger (p < .0001), had a higher proportion of males (p = .0022) and dentists (p < .0001), a lower HBsAg positivity rate (p < .0097), and a higher anti-HBs positivity rate (p < .0001) compared to those in the non-vaccination group. The positivity rate of HBsAg and anti-HBs in the unvaccinated group increased with age, with HBsAg positivity reaching 3.8% in the 70s and anti-HBs positivity reaching 40.4% in the 70s and 66.7% in the 80s.
Conclusions
This study highlights the need to raise awareness about hepatitis prevention vaccination, particularly among dental staff, due to differences in HB vaccination rates across occupations. In particular, they indicated that elderly DHCWs may be more vulnerable to HBV infection. Regular monitoring of the vaccination rate and infection risk is crucial.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
