A spartate Aminotransferase Activity in Crevicular Fluid From Dental Impiants.

Background: Aspartate aminotransferase (AST) is an enzyme normally confined to the cytoplasm of cells, but released to the exracellular environment upon cell death. Its levels are associated with the severity of experimental gingivitis and the loss of periodontal attachement. The aim of the present study was to investigate the presence and activity levels of AST in peri-implant crevic-ular fluid (PCF) healthy and diseased endosseous implants in order to assess if AST in PCF can be further studied as a possible objective diognostic aid in oral implantology.
