Further studies are required to assess the link between other inflammatory markers found in the gingival fluid and the HCV infection [20] and thus to investigate if the HCV-infected patients would have a higher risk to develop periodontal injury or if periodontal-compromised patients with type C hepatitis could have a higher expression of other liver-specific biomarkers, along with some insights into the underlying mechanism.

The mechanism by which HIV antibodies enter saliva is transudation from the serum via gingival fluid, but some additional, not yet understood transport mechanism also appears to be involved in the process.|6~
Alternatively, inflammation may develop as a result of direct toxic effects of concentrated drug in crevicular gingival fluid and/or bacterial plagues.
