Effects of plaque removal with Sonicare^ⓇDiamondClean

Abstract

The aim of this study was to evaluate the plaque removal efficacy of three tooth brushes：the Philips Sonicare Diamond Clean with a medium brush head, Philips Sonicare Diamond Clean with a mini brush head, and the Philips Sonicare Flexcare with a medium brush head. This study was an investigator-blinded,three-brush crossover design study. Twenty dentists with clinically healthy gingiva and without restorative materials or prosthetic teeth participated in this study. Prior to the experiment, the subjects received a professional prophylactic program and were requested to refrain from brushing their teeth for 48 hours. Assessment was carried out using the modified OʼLearyʼs plaque control record (6 sites per tooth) at the baseline and after each brushing interval by one blinded investigator. The PCR score was 100% at the baseline in all subjects. The results showed no statistically significant differences in the PCR score among the three tooth brushes. However, the Sonicare Diamond Clean (DS) provided a more pleasant brushing experience than the Flexcare (FS) in 90% of the subjects, which may be a significant factor advantage for long-term use.
