The aim of the present study was to examine factors associated to the self-reporting of hepatitis B vaccination and immunization status among dentists working in the city of Belo Horizonte, Brazil.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional survey was carried out with 1302 dentists in Belo Horizonte, Brazil. After signing a term of informed consent, the participants answered a structured questionnaire on their knowledge regarding their vaccination and immunization status against hepatitis B. Data on demographic, behavioural and occupational exposure aspects were also collected through questionnaires.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results revealed that 73.8% of the dentists reported having received three doses of the vaccine. Multivariate analysis revealed that gender (p = 0.006), use of individual protective equipment (p = 0.021), history of blood transfusion (p = 0.024) and history of illicit drug use (p = 0.013) were independently associated with vaccination against hepatitis B. Only 14.8% had performed a post-vaccination test. The use of individual protective equipment (p = 0.038), dentists who asked patients about hepatitis during dental treatment (p &lt; 0.001), a family history of hepatitis B (p = 0.003) and work experience (p &lt; 0.05) were independently associated with the post-vaccination test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Although there were a large number of vaccinated dentists in Belo Horizonte, the percentage was less than what was expected, as Brazil offers the National Program of Viral Hepatitis Vaccination, which provides free hepatitis B vaccinations to all healthcare workers. Despite being part of a high risk group for contamination, most of the dentists did not know their immunization status.<\/jats:p><\/jats:sec>","DOI":"10.1186\/1743-422x-7-154","type":"journal-article","created":{"date-parts":[[2010,7,14]],"date-time":"2010-07-14T06:13:52Z","timestamp":1279088032000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Concerns regarding hepatitis B vaccination and post-vaccination test among Brazilian dentists"],"prefix":"10.1186","volume":"7","author":[{"given":"Vera L\u00facia S","family":"Resende","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauro Henrique G","family":"Abreu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saul M","family":"Paiva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ros\u00e2ngela","family":"Teixeira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabela A","family":"Pordeus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2010,7,13]]},"reference":[{"key":"899_CR1","doi-asserted-by":"publisher","first-page":"407","DOI":"10.1017\/S0950268899004537","volume":"125","author":"A Ammon","year":"2000","unstructured":"Ammon A, Reichart PA, Pauli G: Hepatitis B and C among Berlin dental personnel: incidence, risk factors, and effectiveness of barrier prevention measures.
