Among the many functions of human saliva, its digestive and protective properties have attracted the most interest. Human saliva contains a number of physical, physicochemical and chemical agents that protect oral tissues against by various microorganisms and their metabolic products. Among such protective factors, the flushing effect of saliva flow is the most important one, not only because it so effectively removes exogenous and endogenous microorganisms and their products into the gut but also because a steady supply of saliva guarantees continuous presence of both non-immune and immune factors in the mouth. The most important antimicrobial peptides in saliva are: histatins, defensins, lactoferrin, cathelicidins, mucins, calprotectin, lysozyme, oral peroxidase. Antimicrobial peptides are components of complex host secretions, acting synergisticaly with other innate defence molecules to combat infection and control resident microbial populations throughout the oral cavity.
