Recent studies show that subjects with natural gingivitis or periodontitis have elevated levels of salivary cystatins compared to periodontally healthy individuals. Increased glandular output of cystatins in inflammatory conditions suggests an active, most likely protective, rôle for these proteins in inflammatory processes. Furthermore, it has been shown that the development of gingival inflammation is suppressed in smokers during experimental gingivitis.
