a) A sample of artificial interdental area (isosceles triangle) to illustrate the standardized photographic documentation before and after cleaning by the test products. The same test blocks with the decolorized, purified areas of the simulated interdental area are again photographed in order to subsequently perform an (b) evaluation of the cleaned surfaces in percent by a digital image subtraction (Image J, NIH, Bethesda, USA) to calculate the experimental cleaning efficacy (ECE)
