AIMS AND OBJECTIVES: Currently, as a preventive measure against air contamination caused by dental procedures, dust-collecting aspirators such as an extra-oral vacuum aspirator (EOVA) are coming into general use. In this study, we tested the ability of a modified EOVA that uses a household vacuum machine. DESIGN AND SETTING: The study was conducted in two parts. First, the modified EOVA was tested for its ability to eliminate an Escherichia coli aerosol generated in a manikin. Second, the device was tested for its ability to remove the aerosol generated by dental treatment procedures, scaling and drilling a tooth, on human subjects. RESULTS: There was a statistically significant reduction in both the E. coli aerosol and the oral bacterial aerosol during dental treatment procedures. CONCLUSION: The modified EOVA machine is highly effective in preventing air contamination by dental procedures. Its main advantages are that it can easily be modified for use with any dental unit and it is relatively inexpensive.
