Laboratory assessment of the Sensodyne Mikro Aktiv extra soft toothbrush and the Oral-B indicator soft toothbrush.

Abstract The objective of this laboratory study was to assess the Sensodyne Mikro Aktiv extra soft toothbrush, compared with the Oral-B Indicator soft toothbrush, for interproximal access efficacy (IAE). Six toothbrushes of each product were tested four times, for a total of twenty-four tests on each toothbrush design. In the IAE assay, the tooth brushing technique involved independent evaluations of each toothbrush in a vertical or horizontal brushing motion, tooth shapes simulating anterior and posterior teeth, and a brushing weight of 250 g. The brushing apparatus was set to brush for 15 seconds at two strokes per second with a 50 mm stroke. All readings were measured with 3x magnification by a single investigator. The mean IAE value on anterior tooth shapes, with vertical and horizontal brushing, was significantly (p
