– An in vitro model for the purpose of testing the access to interproximal tooth surfaces by toothbrushes is described. The model was used to compare the access of different bristle designs and stiffnesses. Two standardized brushing techniques were used: a horizontal and a vertical one. The test method discriminated significantly between different bristle designs and stiffnesses. With regard to interproximal access the V‐shaped bristles were superior to the straight multitufted ones and soft bristles were better than medium and stiff ones. This study also indicated that the interproximal access increased with increasing pressure within the pressure range chosen. Of the two techniques used in this study the vertical one was superior to the horizontal. The results indicated that some current opinions with regard to mechanical cleaning should be re‐evaluated and clinical testing methods be further developed to enable corresponding in vivo testing.
