Mucosal inflammatory cytokines associated with gingivitis. GCF samples were taken from rhesus macaques before (day 1) and 34 days after induction of gingivitis (GVS) by teeth ligation and a diet of softened food; GCF samples were also taken from control animals (CNT) at the same time points. Cytokine concentrations (in pg/ml) were determined in the GCF by an NHP Luminex assay as described in Materials and Methods; differences in median cytokine concentrations were compared between groups with the Mann-Whitney test.
