Results: Among of 223 participants were retained for the study out of 304 in dental students, the mean age was 23.6(SD 3.5) year and 60.1% were female. 102(45.7%) of dental students had good level of knowledge of HBV infection, the women were 1.17time (95%CI:1.03-1.33, P= .01). more likely to had a good knowledge than man. Participants with 4th year students level were more (95%CI: 0.04(0.00-0.31) P< .001) likely have good level knowledge than another students level. with 96.4% were recognized that dentist and health care worker are at risk of contracting, with 71.8% agree that HBV is the most wide spread. About 63.2%of the students agree that all health care worker should receive the B virus vaccination before working in the dental clinic.
