title: Randomized controlled trial comparing a powered toothbrush with distinct multi-directional cleaning action to a manual flat trim toothbrush.
abstract: OBJECTIVE
  To compare the plaque and gingivitis efficacy of a power toothbrush with distinct multi-directional cleaning action (Colgate® ProClinical® A1500 Power Toothbrush) against a manual flat-trim toothbrush (Oral-B Indicator).
  
  
  METHODS
  This randomized control trial was a single-center, examiner-blind, parallel-group, design and assessed plaque removal after a single brushing, as well as plaque removal and gingivitis reduction after 4 weeks and 12 weeks of brushing. Qualifying subjects used their assigned toothbrush to brush their teeth under supervision after which they were evaluated for plaque (post-brushing). Over the next 12 weeks, subjects brushed unsupervised at home with their assigned toothbrush. After 4 weeks and 12 weeks, subjects returned to the center for plaque and gingivitis examinations.
  
  
  RESULTS
  80 subjects were screened for eligibility and randomized into the study. 79 subjects completed the study. Both toothbrushes provided statistically significant reductions in all plaque index scores at all time points in comparison to the pre-brushing scores. After 4 weeks and 12 weeks, statistically significant reductions in gingivitis and gingivitis severity scores were observed for subjects using the power toothbrush, whereas statistically significant increases in gingivitis and gingivitis severity were observed for subjects using the manual toothbrush. In conclusion, relative to the manual toothbrush, the power toothbrush provided statistically significantly (P < 0.05) greater removal of plaque: whole-mouth (131%), gumline (97.4%), and interproximal (220%), as well as reductions in gingivitis (400%), and gingivitis severity (320%) after 12 weeks of use. Compared to the manual flat-trim toothbrush, the power toothbrush with distinct multi-directional cleaning action demonstrates statistically and clinically significantly greater levels of plaque removal and gingivitis reduction at all time points.
