The threat of hepatitis B from dental school patients. A one-year study
Abstract:
A study was conducted at the Louisiana State University School of Dentistry using the radioimmunoassay technique of serum analysis for presence of hepatitis B surface antigen (HBsAg) in all new patients accepted for treatment over a period of one year. The prevalence was 0.61 percent (22 seropositive patients from a total of 3,626 patients screened). Chronic HBsAg carriers, presence of e antigen, and high titers of antibody to hepatitis B core antigen (anti-HBc) were documented. Eighteen of the 22 seropositive patients had no past history of hepatitis, indicating the inadequacy of a history for revealing carriers of HBsAg.
