OBJECTIVE: We calculated the prevalence and studied the factors associated with hepatitis B vaccination. Reasons for non-vaccination among dentists were investigated. METHODS: A cross-sectional study was performed in Montes Claros, Minas Gerais, from 2007 to 2008, to assess hepatitis B vaccination among practicing dental surgeons. Variables were evaluated using a previously tested structured questionnaire. Data underwent descriptive analysis. Non-conditional logistic regression was used to determine the variables associated with hepatitis B vaccination (p < 0.05). RESULTS: There were 333 subjects eligible for the study, 297 (89.2%) participated, and 283 answered the question about vaccination; of these, 258 (91.2%) completed the three-dose schedule vaccination and 25 (8.8%) were not vaccinated or did not complete the vaccination schedule. Lack of information (48%) was stated as the main reason for not being vaccinated. Variables associated with vaccination were: tobacco use (OR = 2.50; IC95% = 1.22-7.13), alcohol consumption (OR = 2.99; IC95% = 1.16-7.74), satisfaction with the profession (OR = 4.62; IC95% = 1.50-8.25) and knowledge on the post-exposure management protocol (OR = 4.28; IC95% = 1.63-9.26). CONCLUSIONS: We found a high prevalence of complete vaccination among dentists in Montes Claros. It is higher among professionals who do not use tobacco and alcohol, are more satisfied with their profession and know the protocol after occupational exposure. The study suggests that the lack of information is the main reason for not being vaccinated.
