Abstract

PURPOSE

A novel oscillating-rotating electric toothbrush (Oral-B iO) has been developed with a linear magnetic drive, resulting in oscillation-rotations with micro-vibrations. The mechanism directs motor energy directly to the bristle tips. The brush also has a redesigned round brush head and smart pressure sensor to enhance plaque removal and encourage proper brushing technique.

METHODS

The plaque removal and gingival health effects of this new electric toothbrush technology were evaluated in three randomized controlled studies summarized in this supplement, including an 8-week trial versus a manual toothbrush, an 8-week trial versus a premium sonic toothbrush, and a single-brushing, repetitive-use study versus a manual toothbrush.

RESULTS

Outcomes from these studies demonstrate statistically significantly greater plaque removal and gingival health improvements for the Oral-B iO toothbrush technology versus manual and sonic toothbrush controls. Plaque removal advantages demonstrated in the replicate-use single-brushing trial resulted in significant gingival health benefits as evidenced in the longer-term trials. In addition, gingivitis case status assessments based on the American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) guidelines show that over 80% of subjects using the Oral-B iO transitioned from 'gingivitis' (≥10% bleeding sites) at baseline to 'generally healthy' (<10% bleeding sites) at week 8 in both longer-term clinical trials, versus 24% in the manual toothbrush group and 53% in the sonic toothbrush group.

CONCLUSIONS

This uniquely designed oscillating-rotating electric toothbrush with a linear magnetic drive delivers significantly greater plaque removal and gingival health benefits with additional features to improve brushing experience and clinical outcomes.

摘要

目的

开发了一种具有线性磁驱动的新型振荡旋转电动牙刷（Oral-B iO），从而产生具有微振动的振荡-旋转运动。该机制将电机能量直接引导至刷毛尖端。该牙刷还具有重新设计的圆形刷头和智能压力传感器，以增强牙菌斑去除效果并鼓励正确的刷牙技术。

方法

本补充材料总结了三项随机对照研究，评估了这种新型电动牙刷技术的牙菌斑去除和牙龈健康效果，包括与手动牙刷相比的 8 周试验、与高级声波牙刷相比的 8 周试验，以及与手动牙刷相比的单次刷洗、重复使用研究。

结果

这些研究的结果表明，与手动和声波牙刷对照相比，Oral-B iO 电动牙刷技术在牙菌斑去除和牙龈健康改善方面具有统计学上显著的优势。在重复使用单次刷洗试验中表现出的牙菌斑去除优势导致在长期试验中出现显著的牙龈健康益处。此外，根据美国牙周病学会（AAP）和欧洲牙周病学会（EFP）指南进行的牙龈炎病例状态评估显示，在这两项长期临床试验中，超过 80%使用 Oral-B iO 的受试者从基线时的“牙龈炎”（≥10%出血部位）转变为第 8 周时的“基本健康”（<10%出血部位），而手动牙刷组为 24%，声波牙刷组为 53%。
