Comparing Dental Students' Knowledge of and Attitudes Toward Hepatitis B Virus-,Hepatitis C Virus-,and HIV-Infected Patients in Taiwan

This study investigated and compared Taiwanese dental students′ knowledge of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV infection, attitudes toward infected patients, and important factors associated with the willingness to treat infected patients. In 2001, a selfadministered questionnaire survey was conducted on all 1930 dental students enrolled from seven dental schools in Taiwan, with a response rate of 54.4%. Multiple logistic regression analysis was applied to assess the relationship between multiple factors and willingness to treat. Multivariate analysis was used to compare knowledge levels and the willingness. Of the respondents, 80%, 75%, and 49% were willing to treat HBV-, HCV-, and HIV-infected patients, respectively, and differences among the percentages were statistically significant. Students were less knowledgeable about HCV infection compared to HBV and HIV infection. Factors significantly associated with willingness to treat HBV- or HCV-infected patients were: feeling morally responsible and being able to treat infected patients safely. Those feeling morally responsible (odds ratio [OR] = 33.0, 95% confidence interval [CI] = 15.2, 71.8) and those being able to treat infected patients safely (OR = 4.1, 95% CI = 1.7, 9.9) were more willing to treat HIV patients. Taiwanese dental students were more willing to treat HBV- and HCV-infected patients than to treat HIV-infected patients.
