To evaluate the safety and plaque removal efficacy of an advanced rotating-oscillating power toothbrush relative to a sonic toothbrush with either a standard or compact brush head.
Two studies used a randomized, examiner-blind, two-treatment, crossover design. In Study 1, subjects were instructed to use their first randomly assigned toothbrush for five to seven days and then, after abstaining from all oral hygiene for 24 hours, were assessed with the Rustogi, et al. Modified Navy Plaque Index. They then brushed for two minutes and post-brushing plaque scores were recorded. Subjects were assigned to the alternate toothbrush and the procedures were repeated. In Study 2, subjects alternated using both brushes for approximately 10 days, then had four study visits three to four days apart (some variability based on patient scheduling). In Study 1, Oral-B Triumph with a FlossAction brush head and Sonicare Elite 7300 with a full-size, standard head were compared in a two-treatment, two-period crossover study. Study 2 compared Oral-B Triumph with a FlossAction brush head and Sonicare Elite 7300 with a compact head in a two-treatment, four-period crossover study.
Fifty subjects completed Study 1 and 48 completed Study 2. All brushes were found to be safe and significantly reduced plaque after a single brushing. In Study 1, Oral-B Triumph was statistically significantly (p < 0.001) more effective in plaque removal than Sonicare Elite 7300 with the full-size brush head: whole mouth = 24% better, marginal = 31% better, approximal = 21% better. In Study 2, Oral-B Triumph was statistically significantly (p < 0.001) more effective than Sonicare Elite 7300 with the compact brush head: whole mouth = 12.2% better, marginal = 14.6% better, approximal = 12% better.
Oral-B Triumph with its rotation-oscillation action was significantly more effective in single-use plaque removal than Sonicare Elite 7300 with its side-to-side sonic action when fitted with either a standard or a compact brush head.
评估一款先进的旋转振荡式电动牙刷相对于配备标准刷头或紧凑型刷头的声波牙刷在安全性和去除牙菌斑功效方面的表现。
两项研究采用随机、检查者盲法、双治疗、交叉设计。在研究1中，受试者被指示使用其随机分配的第一支牙刷五至七天，然后在停止所有口腔卫生措施24小时后，采用鲁斯托吉等人改良的海军牙菌斑指数进行评估。然后他们刷牙两分钟，并记录刷牙后的牙菌斑分数。受试者改用另一支牙刷，重复上述步骤。在研究2中，受试者交替使用两支牙刷约10天，然后在三到四天内进行四次研究访问（根据患者日程安排会有一些变化）。在研究1中，在一项双治疗、两阶段交叉研究中，比较了配备牙线清洁刷头的欧乐B胜利系列牙刷和配备全尺寸标准刷头的飞利浦声波震动牙刷7300。研究2在一项双治疗、四阶段交叉研究中，比较了配备牙线清洁刷头的欧乐B胜利系列牙刷和配备紧凑型刷头的飞利浦声波震动牙刷7300。
50名受试者完成了研究1，48名受试者完成了研究2。所有牙刷均被发现是安全的，且单次刷牙后能显著减少牙菌斑。在研究1中，配备牙线清洁刷头的欧乐B胜利系列牙刷在去除牙菌斑方面比配备全尺寸刷头的飞利浦声波震动牙刷7300在统计学上有显著更高的效果（p < 0.001）：全口 = 高24%，边缘 = 高31%，邻面 = 高21%。在研究2中，配备牙线清洁刷头的欧乐B胜利系列牙刷比配备紧凑型刷头的飞利浦声波震动牙刷7300在统计学上有显著更高的效果（p < 0.001）：全口 = 高12.2%，边缘 = 高14.6%，邻面 = 高12%。
配备旋转振荡功能的欧乐B胜利系列牙刷在单次使用去除牙菌斑方面比配备横向声波震动功能的飞利浦声波震动牙刷7300显著更有效，无论后者配备的是标准刷头还是紧凑型刷头。
