[Crevicular fluid: active site marker].

Abstract

The qualitative studies of gingival crevicular fluid can be used for a reliable diagnosis of the beginning of active periodontal disease. Some changes in the crevicular fluid components are correlated with rising inflammation both in gingivitis and in periodontitis; the degradation products of the connective tissue as hydroxyproline, and inflammation mediators, as prosaglandine, can be find in it. The concentration of these components in crevicular fluid can be used as a reliable marker to individuate precociously the rising of an active site where an early treatment of periodontal disease can be effected.
