Method for testing and evaluating cleaning effect of electric oral irrigator

The invention discloses a method for testing and evaluating the cleaning effect of an electric oral irrigator, which comprises the following steps of: evaluating the cleaning of stains on a tooth surface and between teeth: smearing pollutants on the surface of a tooth model, cleaning through the electric oral irrigator, and evaluating the occupied area of the residual pollutants, the pollutants being made of spinach; the dental plaque cleaning evaluation method comprises the following steps: mixing streptococcus mutans, streptococcus sanguis and actinomyces viscosus to obtain a mixed bacterial suspension, preparing a biological membrane culture solution from the mixed bacterial suspension, cane sugar and a yeast extract, immersing a tooth model into the biological membrane culture solution for culture, and forming plaque on the tooth model after culture, and comparing and evaluating the tooth model which is cleaned by the electric oral irrigator and the tooth model which is not cleaned by the electric oral ir
