Anonymous data on age, gender, occupation, hepatitis B surface antigen (HBsAg), antibodies to hepatitis B surface antigen (anti\u2010HBs), antibodies to HCV (anti\u2010HCV), history of HB vaccination, and antiviral treatment for individuals with positive anti\u2010HCV were collected.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The positivity rates for HBsAg, anti\u2010HBs, and anti\u2010HCV were 0.5%, 39.7%, and 0.6%, respectively. Dentists had significantly higher rates of anti\u2010HBs positivity (53.9% vs. 34.9%; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001) and anti\u2010HCV positivity (1.4% vs. 0.3%; <jats:italic>p<\/jats:italic>\u2009=\u2009.0080) compared to dental staff. The vaccination and non\u2010vaccination 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%; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001). Those in the vaccination group were younger (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001), had a higher proportion of males (<jats:italic>p<\/jats:italic>\u2009=\u2009.0022) and dentists (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001), a lower HBsAg positivity rate (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0097), and a higher anti\u2010HBs positivity rate (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001) compared to those in the non\u2010vaccination group. The positivity rate of HBsAg and anti\u2010HBs in the unvaccinated group increased with age, with HBsAg positivity reaching 3.8% in the 70s and anti\u2010HBs positivity reaching 40.4% in the 70s and 66.7% in the 80s.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>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.
