[The behavior of trypsin-like proteases in sulcus fluid].

The present study shows results aimed at determining whether levels of a trypsin-like protease in gingival crevicular fluid are associated with disease activity as assessed by the level of gingival inflammation and probing attachment loss. Maximum enzyme level was significantly elevated by groups with gingival inflammation and periodontal destruction. In a long-time study we find a decrease of enzyme activity with clinical therapy by scaling and root planning.
