Polyphenols are natural compounds produced by plants that have various functions, such as defence against microbial pathogens or protection against UV light. Based on their antioxidant activity, a soothing or preventive effect of polyphenols on various inflammatory diseases has been suspected. There is evidence of an anti-inflammatory effect of polyphenols in manifest periodontitis as well as antibacterial properties of these compounds. In addition, it is discussed that dietary polyphenols intervene in mechanisms involved in the pathophysiology of arteriosclerotic changes and their progression.~This randomized, double-blind, placebo-controlled 2-arm, parallel group clinical trial is designed to evaluate the impact of the regular consumption of a polyphenol-containing Maritime Pine (Pinus pinaster) bark extract (Pycnogenol®) on clinical signs of gingival inflammation in a cohort of periodontal aftercare patients
