Research Abstract |
It was presumed that the risk of the hepatitis C virus (HCV) infection of dental health care workers was high rate because the infection route was similar to the Hepatitis B virus. There is a report with a high occupational HCV infection risk of dentist's. On the other hand, the risk also has the report of low. The evaluation concerning the risk is not decided. The purpose of this research is to evaluate the danger of the dental health care worker HCV infection, by the Cohort research. Moreover, it was assumed that it was a purpose of this research to clarify dental health care workers occupational hazard factor. The object : in 833 dental health care workers. The HCV antibody positivity rate was 0.48%. As for this result, the difference was not admitted in the antibody positivity rate of the dental health care worker and the blood donor who considered the average age. Meanwhile, those who changed to positive the antibody were not admitted though the follow-up survey of 889 person age was done. The dental health care worker of 61% experienced the needle stick injury for the pursuit period. However, those who changed to positive the HCV antibody were not seen though such an exposure was received. It was thought that the danger of the HCV infection through the dental treatment was much lower than that of the above-mentioned result.
