Details and patient eligibility


This is a single center, double blinded, randomized, controlled trial. Qualified subjects will be enrolled and randomized to either one of the two study groups: a) using 0.3% triclosan/copolymer/fluoride dentifrice twice daily - b) using a matching control dentifrice (copolymer/fluoride/no triclosan) twice daily.

Full description

The objective of this study is to comparatively evaluate the effects of Colgate Total® toothpaste with triclosan (commercially sold in Israel) and triclosan-free matching placebo toothpaste on markers of inflammation in the bloodstream and to correlate these findings with periodontal disease status in the oral cavity, as determined by the parameters assessed. Periodontal parameters (periodontal pocket dept (PPD), Clinical Attachment loss (CAL)) will be assessed at baseline and after 2, 6 and 12 months of product use. Peripheral blood samples will be drawn from the subjects at baseline and after 2, 6 and 12 months to evaluate the effects of tooth brushing on systemic inflammatory markers (CRP, PGE2, IL-1β, TNF-α).
