| Abstract: | A new method for the sterilization of dental hand-piecxes by the joint action of a high-concentration gaseous ozone sterilizing agent and high-intensity ultraviolet ray has been put forward. Ozone is a broad spectrum bactericide with high efficiency and quick action. In gaseous state, it penetrates into all parts of the objects to be sterilized; while directed radiation of high-intensity ul-traviolet ray on the surface of objects brings a speedy bactericidal effect. The experiment has shown that when contaminated hand-pieces are sterilized by ozone (at>180mg/ cm3) and ultraviolet ray (at > 30000/uW/ cm2)jointly for 10' in a model KX01 dental sterilizer specially developed for the purpose, the bactericidal rate against escherichi-a coli is 100%, staphylococcus aureus 99. 999%and Bacillus subtilis sub-sp. nigra spores 97. 55%. HBs-Ag antigens are totally destroyed. The results of sterilization are most satisfactory. |
