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. As variáveis associadas com relato de vacinação, após ajuste para todas as outras, foram: consumo de tabaco (OR = 2,50; IC95% = 1,22-7,13), consumo de bebidas alcoólicas (OR = 2,99; IC95% = 1,16-7,74), satisfação com a profissão (OR = 4,62; IC95% = 1,50-8,25) e conhecimento sobre protocolo pós-exposição ocupacional (OR = 4,28; IC95% = 1,63-9,26). Conclusões: Verificou-se alta prevalência de vacinação completa, sendo maior entre os não fumantes, os que não consumiam bebidas alcoólicas, os mais satisfeitos com a profissão e os que conheciam um protocolo pós-exposição ocupacional. O estudo sugere que os comportamentos negligentes com a própria saúde se repetem. Há necessidade de campanhas educativas sobre a transmissão da hepatite B, contribuindo para o controle e erradicação dessa grave infecção.Palavras-chaves: Hepatite B. Vacinação. Saúde do trabalhador.

IntroductionHepatitis B infection is one of the major public health problems globally and is the tenth leading cause of death. Worldwide, more than two billion of the population have evidence of past or recent HBV infection and there are more than 350 million chronic carriers of this infection [1]. In India, HBsAg prevalence among the general population ranges from 2 to 8%, which places India in an intermediate endemic zone for HBV [1,2].Occupational exposure of HBV is a well recognized risk for health care workers (HCWs). Throughout the world, millions of healthcare professionals work in health institutions and it is estimated that 600,000 to 800,000 cut and puncture injuries occur among them per year, of which approximately 50% are not registered [3]. According to WHO, the proportion of health-care workers in the general population varied substantially by region (0.2%-2.5%), as did the average number of injuries per health-care worker (0.2-4.7 sharps injuries per year). The annual proportion of health-care workers exposed to blood-borne pathogens was 5.9% for HBV, corresponding to about 66,000 HBV infections in health-care workers worldwide [4].In developing regions, 40%-65% of HBV infections in health-care workers occurred due to per-cutaneous occupational exposure. In contrast, the fraction of HBV was less than 10%, in developed regions, largely because of immunization and post-exposure prophylaxis [4]. Risk of HBV infection is primarily related to the degree of contact with blood in the workplace and also to the hepatitis B-e antigen (HBeAg) status of the source person. Studies have shown that of the HCWs who sustained injuries from needles contaminated with blood containing HBV, the risk of developing clinical hepatitis is variable from 1-6% if source is HBeAg negative to 22-31% if source is HBeAg positive [5,6]. Although most of the HBV infections in healthcare workers are attributed to per-cutaneous exposure, in many studies, most infected HCWs could not recall any overt per-cutaneous injury [7]. In addition, HBV has been demonstrated to survive in dried blood, at room temperature, on environmental surfaces, for at least one week. Thus, HBV infections that occur in HCWs with no history of exposure might have resulted from direct or indirect blood or body fluid exposures that inoculated HBV into the mucosal surfaces or cutaneous scratches and other lesions [5,6]. The potential for HBV transmission through contact with environmental surfaces has been demonstrated in investigations of HBV outbreaks among patients and staff of hemo-dialysis units [8,9].Blood contains the highest HBV titres of all body fluids and is the most important vehicle of transmission in the healthcare settings. HBsAg is also found in several other body fluids, including breast milk, bile, cerebrospinal fluid, feces, nasopharyngeal washings, saliva, semen, sweat, and synovial fluid. However, most body fluids are not efficient vehicles of transmission because they contain low quantities of infectious HBV, despite the presence of HBsAg [...

Introduction: Hepatitis B is an infectious viral disease that causes inflammation of the liver. It is transmitted through body secretions and fluids, including genital secretions, saliva and blood. The objective of this study was to assess the attitudes and practices of dental surgeons in the face infection of Hepatitis B. Methods: This was a descriptive, cross-sectional a sample of 171 dental surgeons. Probabilistic multi-stage, stratified, and systematic sampling was used. Using a questionnaire, we gathered variables related to the attitudes and practices of dentists with respect to Hep B. Results: Nearly 22% of dentists were not vaccinated against hepatitis B virus; Compliance with the use of gloves, glasses, professional clothing, and hygiene in dental offices was not systematic. Blood exposure accidents (BEA) were common, with nearly 13% suffering from needle stick injuries, 10% from eye splashes and about 6% from sharp instruments. The majority of the actions to be taken in the event of (BEA) were disinfection in the event of sticks or injuries (52.1%) and rinsing in the event of eye splashes (66.7%). Conclusion: Dentists should be educated and informed about the need for vaccination and hygiene, sterilization, and good behaviour in case of exposure to blood.
