The number of polymorphonuclear leucocytes (PMNs) in the products of gingival washing and the rate of gingival fluid flow were measured in eight volunteers during a period of experimental gingivitis on the upper dental arch. Both parameters increased significantly during the 21 days of no brushing. However, the concentration of PMNs increased, between day 0 and day 21, by a factor of 2.1, whereas the flow of gingival fluid collected on teeth no 13 and 21 showed a 5.4 fold increase during the same period. When the amount of gingival fluid was very low (at days 0 and 28), the number of migrating PMNs was still rather high. For each volunteer, the concentration of PMNs in the washings through the period of experimental gingivitis was not always correlated to the rate of gingival fluid flow. These data confirm previous findings on dogs that sulcular PMNs emigration and flow of gingival fluid could be two independent phenomena.
