  1. Data are Wilcoxon–Mann–Whitney (WMW) U-statistic and p-values. The cleaning efficacy (% plaque removal) of six toothbrushes (ComPro, TrueWhi, SensGu, RepPro, RapRe, Control) was assessed using APP-index at 30 fields per tooth using three different brushing movements. The total values given are derived from % plaque removal using brushing of the following areas: buccal, mesial, distal, ABCDF buccal, ABCDF lingual, W buccal, W lingual, W1 + W2 mesial, W1 + W2 distal. The cleaning efficacy (% plaque removal) of each single toothbrush was compared against each other via a WMW test (*not significant using Bonferroni correction). APP: automated plaque planimetry; ComPro: Complete Protection Soft; N/A: not applicable; NS: not significant (on either test); RapRe: Rapid Relief Soft; RepPro: Repair & Protect Soft; SD, standard deviation; SensGu: Sensitivity & Gum Soft; TrueWhi: True White Medium; WMW: Wilcoxon–Mann–Whitney.
