Aerosol containing patients' blood and drill dust from dental plaque microorganisms, tooth substances and filling materials can cause environmental pollution in the dental clinic. Curently, as a preventive measure against air pollution caused by the dental procedures, dust-collecting aspirators such as an extra-oral vacuum aspirator (EOVA) are coming into general use. In this experiment, we tested the eliminating effects of modified EOVA from the household vacuum machine with the E. coli solution aerosol in a manikin and the aerosol from actual dental treatment procedures, scaling and drilling a tooth, in human subjects. The results demonstrated that this inexpensive modified machine is highly effective.
