Abstract
Methods are included for quantitating the efficacy of oral care products at dislodging cells from biofilm test surfaces or inhibit or delay the accumulation of cells on a test surface. More specifically, the inventive methods measure the effectiveness of compositions and appliances in a test environment that models biofilm surface orientations that are encountered on a tooth surface, i.e. interproximal and subgingival tooth surfaces. The use of test surfaces that are removably attachable to a tooth prosthesis allow a variety of different quantitative methods to be applied to determine the amount of cells removed or deposited in a biofilm.
