Safety and Efficacy of a Novel Toothbrush Utilizing RF Energy for Teeth Shade Whitening and the Reduction of Teeth Stains

Methods: This was a single-blind double arm prospective study, including 4 clinical visits that were conducted every two weeks. Subjects were randomized to one of two study groups, receiving either the ToothWaveTM or control toothbrush, and performed twice daily brushing during a test period of 6 weeks. Teeth stains and shade were assessed using the Lobene stain index and Vita Bleached guide 3D Master, at baseline and after 4 and 6 weeks of brushing. Results were compared within each group and between the groups; delta values (reduction from baseline) were also compared between the groups. Statistical analyses were conducted using the Mann Whitney non-parametric model.
