What is Efficacy of a prototype brush head for a powered toothbrush: A multicentre study about?

## Abstract **Primary objective:** To evaluate a multicentre clinical trial design for testing powered toothbrushes. **Secondary objective:** To compare the efficacy of a prototype brush head (N2.3) for the Philips Jordan Sensiflex 2000 powered toothbrush (PTB) to that of Braun Oral‐B D15 PTB in removing dental plaque **Material and methods:** 137 volunteers (ages 18–25 years) were recruited to this 3‐centre, 2‐week, 2‐group, 2‐treatment, single‐blind trial. Plaque was recorded at screening and again 14 days later at baseline. Stratification of subjects, for gender and screening PI, occurred at baseline. Subjects were then asked to abstain from all oral hygiene measures for 48 h followed by a supervised episode of brushing for 3 min with the allocated PTB. The allocated PTB was used at home for the next 12 days before a second abstinence from all oral hygiene measures for the 48 h prior to a second supervised brushing episode. Plaque levels were scored using a modification of the Quigley & Hein plaque index (PI) at full mouth (FM), interproximal (IP) and smooth surfaces (SS). To enable the means of the __within__ subject differences (pre to postbrushing) to be compared between grou
