Relationship of the Subgingival Microbiota to a Chairside Test for Aspartate Aminotransferase in Gingival Crevicular Fluid

Abstract

The present study showed that at AST-positive sites, there is a higher prevalence and higher proportion of certain periodontal pathogens. Although only the correlation of P. gingivalis and AST values was statistically significant, the results imply that certain periodontal pathogens may be associated with elevation of AST levels in GCF.
