Comparative clinical trials and the changing marketplace for oral care: innovation, evidence and implications.
The development of a trayless bleaching system (Crest Whitestrips) and a novel battery-powered toothbrush (Crest SpinBrush) has fueled growth in the bleaching and power toothbrush markets. Beyond offering convenient, low-cost options for patients, the effectiveness of each product is supported by a robust clinical program. New comparative research involving these products expands evidence on the clinical meaningfulness of the benefits of this whitening system and powered toothbrush for patient care.
