This study investigated the effect of a chemoattractant, N‐formylmethionyi‐leucyl‐phenylalanine (FMLP), upon skin window migration of neutrophils into filters in 5 patients with a history of localized juvenile periodontitis (LJP) and 8 controls. On 2 occasions, each subject had 2 superficial skin abrasions made on the inner aspect of the forearm. Initial periodontal treatment was carried out on the disease group between the visits. On one skin window filters were placed that were soaked in physiological saline, and on the other filters soaked with FMLP. Leading fronts and cell densities were measured in each filter. At visit 1, LJP subjects had significantly lower leading fronts and cell densities. At visit 2, the differences were insignificant. The leading fronts for the LJP group were significantly improved on the second visit. No difference was observed between saline and FMLP. The findings of this study indicate that neutrophil migration is reduced in LJP patients where treatment is not involved, and that FMLP has no effect on neutrophil migration from the skin windows under the conditions of this study.
