title: A plaque removal study comparing two advanced-design oscillating battery-powered toothbrushes.
abstract: OBJECTIVE
  The objective of this study was to compare the plaque removal efficacy of two advanced-design battery-powered toothbrushes (Crest SpinBrush Pro and Oral-B CrossAction Power) following a single use.
  
  
  METHODS
  This study was a randomized, controlled, examiner-blind, four-period crossover design, which examined plaque removal with the two toothbrushes following a single use by 40 subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index.
  
  
  RESULTS
  Average baseline plaque scores were 2.915 and 2.883 for the SpinBrush Pro and CrossAction Power toothbrush treatments, respectively. The SpinBrush Pro toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.802, while the CrossAction Power toothbrush delivered an adjusted mean difference of 0.667. The SpinBrush Pro toothbrush, on average, had 20.2% greater plaque removal scores relative to the CrossAction Power toothbrush. These results were statistically significant (p < 0.001). The observed results on the buccal and lingual surfaces were consistent with the overall results, and were statistically significant.
  
  
  CONCLUSIONS
  The results of this study support the conclusion that the SpinBrush Pro removes statistically significantly greater amounts of plaque over a one-minute brushing period compared to the CrossAction Power toothbrush.
