 AB    Hepatitis B and the acquired immunodeficiency syndrome are serious
       diseases because of their poor prognoses. The increasing awareness of
       the latter has highlighted the need for adequate precautions against
       cross contamination. However, the risk to dental personnel is still far
       higher from hepatitis B than it is from the human immunodeficiency
       virus, and the hepatitis virus is more transmissible, especially because
       it occurs in saliva. The principal potential route of transmission to
       dental laboratory personnel is via infected impressions. A number of
       papers have appeared in the literature examining the effects of various
       disinfecting and sterilising procedures on the accuracy and surface
       quality of impression materials. This paper reviews this literature and
       draws upon the findings to recommend a protocol for the handling of
       impressions to prevent cross contamination.
