This clinical study compared the ability of a sonic toothbrush to remove plaque and control gingivitis with that of an oscillating/rotating electric toothbrush. One-hundred and sixteen subjects from a general population were randomly allocated to either a sonic toothbrush group (Sonicare) or an electric toothbrush group (Braun Oral-B Plaque Remover). After 8 weeks use, there was found to be no statistically significant difference in either plaque removal or gingival index between the two groups. Both devices were found to be safe, but whereas 100% of volunteers in the Braun Oral-B Plaque Remover group expressed a wish to continue using the toothbrush, approximately 25% of the Sonicare group did not like the device and said that they would not continue to use it. The Sonicare device was found to offer no advantages in clinical terms over an established oscillating/rotating electric toothbrush (Braun Oral-B Plaque Remover) with respect to removal of supragingival plaque or improvement in gingival health.
这项临床研究比较了声波牙刷与旋转振动式电动牙刷在清除牙菌斑和控制牙龈炎方面的能力。从普通人群中选取了116名受试者，随机分为声波牙刷组（飞利浦Sonicare）和电动牙刷组（博朗欧乐-B牙菌斑清除器）。使用8周后，发现两组在牙菌斑清除或牙龈指数方面均无统计学上的显著差异。两种牙刷都被证明是安全的，但是博朗欧乐-B牙菌斑清除器组100% 的志愿者表示希望继续使用该牙刷，而飞利浦Sonicare组约25% 的人不喜欢该设备，并表示不会继续使用。在清除龈上牙菌斑或改善牙龈健康方面，研究发现飞利浦Sonicare声波牙刷在临床上并不比成熟的旋转振动式电动牙刷（博朗欧乐-B牙菌斑清除器）更具优势。
