Blinded Clinical Evaluation of a New Toothbrush Design.

Objective: The purpose of this single-blind, crossover study was to compare plaque removal associated with a new manual toothbrush, the O'Nano and a best-selling, commercially available manual toothbrush, the Oral-B Indicator 40. The O'Nano toothbrush has a patented "one-piece molded design" made of Thermal Plastic Urethane, a plastic that has been used in medical devices.

Methodology: Over a six-week period, 40 subjects participated.
