title: Comparison of plaque removing ability of one standard and two flexible-head toothbrushes.
abstract: OBJECTIVE
  This pilot study compared the plaque removing ability of two flexible-head toothbrushes and one nonflexible-head toothbrush.
  
  
  METHODS
  Twenty individuals meeting specific criteria participated. Three quadrants on each subject were disclosed and scored using the Turesky modification of the Quigley-Hein plaque index. For consistency, one dental hygienist performed all brushing and another performed all indices. Pre- and post-brushing scores were compared using t-tests and analysis of variance (ANOVA) to determine differences.
  
  
  RESULTS
  Differences between pre- and post-brushing scores of all groups were significant (p > 0.005). However, no significant differences were detected between mean scores of the test toothbrush groups and the control group of the two test toothbrush groups, or among the means of all groups.
  
  
  CONCLUSIONS
  No differences in plaque removing ability were found between or among the toothbrushes tested.
