The 2005 randomized control trial {1} concluded that:
This randomized, controlled comparative clinical trial demonstrated that rinsing twice daily with the experimental alcohol-free 0.07% CPC rinse provides antiplaque and antigingivitis efficacy similar to that of the positive control EO rinse, a recognized antiplaque and antigingivitis mouthrinse that contains alcohol.
However, the authors have a conflict of interest since they work for Procter & Gamble, which owns Crest.
The 2018 randomized control trial {2} came to the same conclusion but also has some competing interest (authors working for Johnson & Johnson Consumer Inc).
Have independent studies confirmed that alcohol-free mouthrinses have the same efficacy in terms of antiplaque and antigingivitis effect as mouthrinses that contain alcohol?
