The authors aimed to evaluate the effect of a novel radiofrequency (RF) toothbrush on tooth stains and shades compared with a sonic vibrating toothbrush (CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush, Ranir) that earned the American Dental Association Seal of Acceptance.
The authors conducted a single-blind prospective study over 6 weeks. Participants were randomized to 1 of 2 study groups to receive either an RF toothbrush (ToothWave, Home Skinovations [test]) or a sonic vibrating toothbrush (SmileSonic powered toothbrush, Ranir [control]) and performed twice-daily toothbrushing with fluoridated toothpaste (Crest Cavity Protection, Procter & Gamble) for 6 weeks. Tooth stains and shades were assessed using the Lobene Stain Index and VITA Bleachedguide 3D-MASTER shade guide (VITA North America) at baseline and after 4 and 6 weeks of toothbrushing. In addition, the VITA Easyshade Advance 4.0 spectrophotometer (VITA North America) was used for shade evaluation. Safety was evaluated by means of oral soft-tissue examinations at each visit. Percentage reduction from baseline was compared between the groups. Statistical analyses were conducted using Mann-Whitney nonparametric model.
Eighty-six participants (43 in each group) completed the study with fully evaluable data. At baseline, the groups did not differ significantly in mean measurement scores. Percentage reductions of the measured scores were significantly greater (more extrinsic stain removal and whitening) in the test group than in the control group (P < .001). Both toothbrushes were well-tolerated, and no device-related adverse events were reported during the study.
The RF toothbrush produced substantial benefits in the reduction of tooth stains and whitening of tooth shade compared with a powered toothbrush (CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush, Ranir) that earned the American Dental Association Seal of Acceptance.
The novel RF toothbrush is a safe and effective tool for stain removal and tooth whitening and can serve as an alternative to other whitening agents. This clinical trial was registered at ClinicalTrials.gov. The registration number is NCT03885609.
作者旨在评估新型射频（RF）牙刷与获得美国牙科协会认可标志的声波振动牙刷（CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush，Ranir）相比对牙齿污渍和色泽的影响。
作者进行了为期 6 周的单盲前瞻性研究。参与者随机分为 2 个研究组中的 1 组，分别使用 RF 牙刷（ToothWave，Home Skinovations[试验]）或声波振动牙刷（SmileSonic 动力牙刷，Ranir[对照]），并使用含氟牙膏（佳洁士防蛀修护牙膏，宝洁公司）每天刷牙两次，持续 6 周。在基线和刷牙 4 周和 6 周后，使用 Lobene 染色指数和 Vita Bleachedguide 3D-MASTER 比色指南（VITA North America）评估牙齿污渍和色泽。此外，使用 Vita Easyshade Advance 4.0 分光光度计（VITA North America）进行比色评估。每次就诊时均通过口腔软组织检查评估安全性。比较两组之间从基线的百分比降低。使用 Mann-Whitney 非参数模型进行统计分析。
86 名参与者（每组 43 名）完成了研究并获得了完全可评估的数据。基线时，两组的平均测量评分无显著差异。试验组的测量评分降低百分比显著大于对照组（更多的外源性污渍去除和增白）（P<.001）。两种牙刷均具有良好的耐受性，在研究期间未报告与设备相关的不良事件。
与获得美国牙科协会认可标志的声波振动牙刷（CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush，Ranir）相比，RF 牙刷在减少牙齿污渍和增白牙齿色泽方面具有显著优势。
新型 RF 牙刷是一种安全有效的牙齿去渍和增白工具，可作为其他增白剂的替代品。这项临床试验已在 ClinicalTrials.gov 注册。注册号为 NCT03885609。
