This study is aimed at offering basic data about prevention of Hepatitis B virus and infection control to dental hygiene students who will work mostly at dental offices which are characteristically exposed to a high risk of HBV infection. For this study, surveyed were 188 sophomores and juniors of the dental hygiene department who volunteered to undergo the tests of HBsAg and HBsAb. The examination of the blood collected from the samples and analysis of their perception about hygiene resulted in following conclusion: Positive HBsAg Four was found in 4 testees(2.1%) while 118(62.8%) revealed positive HBsAb. Juniors showed higher positive rate in HBsAg whereas sophomores had higher positive rate in HBsAb. But such difference has statistically no significance. Generally, students seemed to pay little attention to HBV, judging from the survey of their perception about the present state of HBsAg and HBsAb(p>0.05), conduct of infection(p<0.05), completion of 3 requested vaccinations(p>0.05), and formation of antibody(p>0.05). With regard to the infection routes of HBV, most students(92.4%) replied "through blood", which is statistically insignificant, though. Next ratio goes to the reply "through contaminated injectors". This reply came more from sophomores than from juniors, a difference which is statistically significant(p<0.05). The lowest rate of possible infection(29.2%) was thought to be "through breast-feeding of a positive mother"(p<0.05). In general, it turned out that sophomores had more knowledge about the infection routes of HBV than juniors. In terms of clinical history among family members, 6(3.1%) reported that some of their family members are currently suffering from a liver complaint, 3(1.6%) replied their family members were once afflicted, and 4(2.1%) said their members died of hepatitis. Except 10(4.7%), all the surveyees replied that their states of health are better than normal. Generally, sophomores are healthier than juniors except for the very health case, a difference which is statistically of no value.
