“…This theme will be approached together with others that promote self-care and life improvement, including smoking prevention and alcohol use, among others. In addition to preventing HBV infection, vaccination is also aimed at eliminating the group of chronically infected individuals 23 , which restricts transmission to susceptible individuals, thus contributing to the eradication of this serious infection.…”

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.

“…Chronic HBV infection is the primary risk factor for the development of HCC (Mahboobi et al, 2010). After decades of chronic hepatitis, about 30-40% of patients progress into liver cirrhosis, and of them, around 1-5% subsequently develop HCC (Liu and Kao, 2007).…”

Summary. -Hepatocellular carcinoma (HCC) is one of the most common malignant diseases and has the fourth highest mortality rate worldwide. Chronic hepatitis B virus (HBV) infection has been identified as a major risk factor in HCC. Currently available evidence support a critical role of hepatitis B virus x (HBx) gene and protein in the pathogenesis of HBV-induced HCC. HBx protein is a multifunctional regulator that modulates cellular signal transduction pathways, transcriptional regulations, cell cycle progress, DNA repair, apoptosis, and genetic stability by interacting with different host factors. This review describes the current state of knowledge about the biological roles of this protein in the development of HCC. Abbreviations: DNMTs = DNA methyltransferases; HBV = hepatitis B virus; HBx = hepatitis B x protein; HCC = hepatocellular carcinoma; MMP = matrix metalloproteinase; MTA = metastasisassociated protein; RAR-β2 = retinoic acid receptor β2; TSGs = tumor suppressor genes; XPB = xeroderma pigmentosum B

“…While dentists and oral surgeons are in the first rank, dental students are ranked sixth (9). Hepatitis B can transmit from dentist to patient or patient to dentist, even from one patient to another in the dental office.…”

“…Similarly, clinical training begin at the end of 3 rd year in Turkey. But, in the preclinical training started at the 1st year, the dental students are also at risk of infection, as the virus remains viable for more than 24 hours under natural circumstances and for more than one week in plastery casts which students use in their preclinical training (9). Therefore, all students in the faculty were included in our study.…”

Aim: Dentists are at high risk of hepatitis B infection. The aim of this study was to evaluate the knowledge of students from Ordu univeriyt, faculty of dentistry on hepatitis Materials and Methods: Questionnaires consisting of 76 questions related to students' socio-demographic status, knowledge of hepatitis infection about the ways of transmission, prevention and risk groups, and vaccination status were distributed to all dental students. Results: Total of 155 students participated in the study and completed the questionairre. The level of knowledge of the 4 th and 5 th year students was significantly higher than the other students (p=0.001). Fifth year students had significantly better knowledge about the transmission and prevention ways of the hepatitis when compared with the 1st year students B (p=0.001). Although, only 60% percent of the students have been vaccinated, the vaccination rates were higher in both 4 th and 5 th year-students when compared to the other classes. Fourty-one percent of the students did not know that HBV is contagious during asymptomatic period. Conclusion: There was a lack of knowledge about the hepatitis B infection especially among the 1 st and 2 nd year students. Therefore, the continuous education of infectious diseases is required starting from the first year of the dental school.
