In vitro assessment of oral care products - Evaluation of toothbrush performance.

In vitro methods can contribute to oral care product development, helping to strengthen claims and rank the efficiency of different designs, potentially accelerating the selection process and speed to market. In this study, toothbrush design was studied in terms of cleaning performance using an in vitro pellicle cleaning ratio test (PCR). Download this whitepaper to learn how this testing approach demonstrates the potential to compare toothbrushes of different design, construction, the specific array or spacing of the tufts and other features of toothbrush design.
