 The purpose of this study is to evaluate a new sea salt mouth rinse containing xylitol and the antibacterial enzyme, lysozyme on biofilm formation and gingival health in a group of young adults. Xylitol is a well-established non-sugar sweetener and an anti-caries agent. The use of this polyol results in loosely adherent biofilms by reducing the amount of extracellular lipopolysaccharides and lipoteichoic acids, facilitating its easy removal by mechanical means. Lysozymes are antibacterial proteins that hydrolyze the linkage between N-acetylmuramic acid and N-acetylglucosamine of peptidoglycan in the cell wall of Gram bacteria effectively limiting growth.
