This study is aimed at providing basic data for measures to prevent dental hygienists who are highly exposed to hepatitis-B virus due to their characteristic working conditions from being infected of it. In order to determine their perception and the extent of their exposure to the risk of infection with hepatitis-B virus, a survey was conducted with questionnaires distributed to 354 dental hygienists who are working at dental offices in Seoul . Gyeongi and Jeolla provincial areas. From the survey, following conclusions could be drawn: 1. Sixty three point seven to 100 percent of them are found to have been vaccinated against hepatitis-B virus as is generally expected from their working environment. 2. Their general characters are found to be statistically significant in terms of vaccinating point of time among those who have been vaccinated. Most respondents are either vaccinated one year or 5 years ago. The completion of 3 requested vaccinations lies in the level of 64.3%~100% depending on the general characters. By age, the best result comes from the age group of 25~29, followed by the groups older than 30 and 20-24 in order (p < 0.05). Formation of antibody belongs to the level of 45%~100% generally. But statistically significant of them is the extremely unhealthy state with 100%, followed by normal, generally healthy, very healthy and not healthy in sequence (p < 0.05). 3. In terms of family's clinical history, it is known that the older (p < 0.01), the more unhealthy (p < 0.01) and the married (p < 0.01), the more possibility of having anamnesis of hepatitis-B virus infection. 4. The level of knowledge about Hepatitis-B virus is shown to be in the extent of 4.39~5.01 out of maximum 8 points in general terms. 5. It is revealed that there are high chances for dental hygienists to get spattered with body matters of patients like blood or sputum on their faces in general characters (87.%~100%). 6. A high rate (75%~100%) of respondents has experienced being shot by needles. The older(p < 0.05) and the longer(p < 0.05) their career, the higher the rate becomes.
