ABSTRACT:
The invention provides a method for indicating the level of oral microbial activity comprising providing a sterile liquid for introduction into the oral cavity for swishing therein, providing a transparent vessel having therein an indicator which undergoes a characteristic color change in the presence of oxygen-consuming microbes and placing the swished liquid together with nutrients to enhance microbial growth in the vessel, whereby the indicator undergoes a color change as a function of time, which color change is an indication of the level of microbial activity in the swished expectorated liquid. The invention also provides a kit for use in carrying out the method comprising a sterile liquid, a transparent vessel for use in receiving the expectorate, and an indicator to be provided in the vessel to produce a visual indication of the level of microbial activity in the expectorated liquid.
