title: Evaluation of several brushing motion combinations in relation to plaque-removing efficacy with Oral-B CrossAction Power: a professional brushing study.
abstract: OBJECTIVE
  The aim of this study was to evaluate the additional effect of a newly developed battery-operated brush Oral-B CrossAction Power with a hybrid brush head design (CAPB). The brush combines an oscillating/rotating part, a PowerHead(R), with a non-moving part with CrissCross bristles. It was compared with a manual control toothbrush Butler GUM 311 (CTB).
  
  
  METHODS
  Thirty subjects were requested not to brush their teeth 48 h prior to the examination, when plaque removal efficacy was assessed by scoring plaque before and after brushing. Plaque was assessed according to the Silness & Loë Index at six sites per tooth. Subjects were brushed by a dentist using one of the four randomly chosen procedures of brushing in each quadrant. The CAPB was used with three different modes of brushing each in different randomly chosen quadrants, with the manual toothbrush being used in the remaining quadrant as a control.
  
  
  RESULTS
  The baseline plaque levels ranged from 1.69 to 1.74 and the end levels ranged from 0.39 to 0.45. In terms of percentage, the results with the four procedures run from 75% to 79%. These differences between the battery brush and manual brush irrespective of the brushing mode used were not statistically significant.
  
  
  CONCLUSIONS
  The results of this Professional Brushing Study show that the CrossAction Power toothbrush was as effective as a regular manual toothbrush.
