Plaque removal efficacy of an advanced rotation-oscillation power toothbrush versus a new sonic toothbrush.

摘要: PURPOSE To evaluate the plaque removal efficacy and safety of an advanced rotation-oscillation power toothbrush relative to a newly-introduced sonic toothbrush. METHODS This study used randomized, examiner-blind, two-treatment, four-period, four-sequence crossover design. Subjects received both toothbrushes (Oral-B Triumph Sonicare FlexCare) standard dentifrice from site each at home during acclimation phase prior their measurement visits. After abstaining all oral hygiene for 24 hours, subjects returned were assessed with Rustogi Modified Navy Plaque Index. They then brushed 2 minutes first randomly-assigned post-brushing scores recorded. procedure was followed three additional visits, using normal at-home 2- 5-day washout periods between always abstained hours RESULTS 45 completed study. Both brushes found be safe significantly reduced after single brushing. Oral-B statistically (P < 0.0001) more effective in than FlexCare whole mouth scores, gingival marginal interproximal scores. Compared FlexCare, adjusted mean reduction 21%, 23% 22% greater mouth, areas, respectively.
