Sumario: | OBJECTIVES: To evaluate the effect of a novel radiofrequency (RF)‐utilizing toothbrush on reduction of stains and improvement of teeth shade. MATERIALS AND METHODS: This was an open label, prospective study, including six clinical visits that were conducted over a period of 8 weeks. Subjects performed twice daily brushing using a novel RF‐utilizing toothbrush, used manually with no mechanical vibration. Teeth shade and stains were assessed using Vita Easyshade advanced 4.0 device and a visual assessment of standardized digital photographs, before, and following 4 and 8 weeks of treatment. RESULTS: Twelve subjects completed the study with fully evaluable data. A notable shade improvement (whitening) was observed between the visits according to the average scores of teeth whitening index per subject. Statistical analysis conducted by the unstructured mix model confirmed a significant reduction in the average score of whitening index between baseline and visit 5 (p < 0.001) as well as between baseline and visit 6 (p < 0.001). No significant difference was found between the average teeth shade in visit 5 as compared to visit 6 (p = 0.918). No significant difference was found in teeth shade between females and males; however, subjects age was significantly correlated with teeth shade (p < 0.001). Digital photographs indicated a notable reduction in visible dark stains. The toothbrush was well tolerated and no device‐related adverse events were reported during the study. CONCLUSIONS: The novel RF‐utilizing toothbrush produced significant benefits relating to teeth whitening and stains reduction, following one and 8 weeks of brushing. |
