Blinded Clinical Evaluation

In 2005, a single-blind crossover study was conducted to compare plaque removal using Curvex against the Oral-B 40 Indicator, widely recognized as the best-selling toothbrush in the world.  Led by

Dr. Lisa Harpenau at the University of the Pacific Arthur A. Dugoni School of Dentistry, this five-week study demonstrated that while the Curvex toothbrush has a 25% softer filament (0.006 inches vs. 0.008 inches), it is as effective as the Oral-B in plaque removal.
