The PerioBrush and PerioSystem provide unsurpassed plaque removal. University of Pennsylvania, 1987. A Study of the Effect of Four Oral Hygiene Methods on Plaque Accumulation. Periodontal Health and Subgingival Microbiology. University of California at San Francisco, 1987.
Studies clearly demonstrate effectiveness of products in removing plaque.
Of interest in Yankell study is that plaque removal was accomplished without dentifrice, as recommended by Interplak. Despite this the PerioBrush alone equalled or bettered the plaque removal of the Interplak brush. Additional decay protection would also be gained by the use of fluoride containing dentifrice. Additional plaque removal could also have been produced by the use of thePerioSystem irrigator. The Robertson study compared the PerioBrush, with and without irrigation to traditional manual oral hygiene techniques.
