MARTINS, Andréa Maria Eleutério de Barros Lima  and  BARRETO, Sandhi Maria. Hepatitis B vaccination among dentists. Rev. Saúde Pública [online]. 2003, vol.37, n.3, pp.333-338. ISSN 1518-8787.

OBJECTIVE: Serological studies in several countries have found a higher prevalence of hepatitis B virus (HBV) among dentists when compared to the general population, especially among surgical specialties. The present study was carried out to determine the prevalence of hepatitis B (HB) vaccination and factors associated with no vaccination and incomplete vaccination among dentists. METHODS: A survey was conducted among 299 dentists living in Montes Claros, southeast Brazil, using a self-administered questionnaire. HBV vaccination prevalence was determined according to the number of doses of vaccine and factors associated with no vaccination or incomplete HBV vaccination were investigated using multinomial logistic regression analysis. RESULTS: Participation rate in the study was very high (296/299). Of the participants, 74.9% received three doses of HBV vaccine, 14% two doses, 2% a single dosis and 10% were not vaccinated. Complete vaccination rate was higher among surgeons and periodontists (89%). The main reason reported for not being vaccinated or incomplete vaccination was the need of more information. No vaccination was significantly higher among dentists aged 40 years and over (OR=8.62; 95%CI: 1.88-39.41) and those who did not attend refreshment courses in the last two years prior to the survey (OR=2.72; 95%CI: 1.02-7.22). Incomplete vaccination was positively associated with non-use of gloves during work (OR=2.32; 95%CI: 1.08-4.97). CONCLUSIONS: Lack of information, possibly associated to lower attendance to refreshment courses, seems to be one of the main factors affecting the vaccination rate.
