Longitudinal study of volatile fatty acids in the gingival crevicular fluid of patients with periodontitis before and after nonsurgical therapy

Conclusions:? The concentration of formic acid in the gingival crevicular fluid has an inverse relationship with the severity of periodontitis, whereas the increased concentrations of butyric and isovelaric acids during the long?term observation period after therapy may indicate the status of recolonization of periodontal pathogens and reflect the subgingival ecology. These two fatty acids could be used as indicators for the development and progression of periodontitis. (Source: Journal of Periodontal Research)
