Hydrogen sulfide production from gingival crevicular fluid

A METHOD was developed and evaluated in a pilot study to determine a relationship between gingival health, crevicular fluid flow and the production of H2S from the crevicular fluid. A moderate degree of correlation was observed between the crevicular fluid volume and the gingival index. A stronger correlation was obtained between the crevicular fluid volume and H2S production by the crevicular fluid. The method described could prove useful in evaluating gingival health and disease objectively and for monitoring the activity of periodontitis.
