WebA 20 µl of whole saliva was immediately processed for benzamine PMN staining as described. We found that in 57% of patients the PMN count was more than 106 cells/ml, above the PMNs count found in healthy subjects [7]. In summary, this study demonstrated that it is possible to quantify salivary neutrophils using the benzidine technique.
