title: Relationship of human gingival crevicular fluid polyamine concentration to the percentage of spirochaetes in subgingival dental plaque.
abstract: This relationship was examined at 45 inflamed periodontitis sites in 28 patients. A statistically significant positive correlation between polyamine concentration and spirochaetes was observed overall (r = 0.551, p = 0.0001). Within subgroups of this population (n = 15 each), there was no such relationship among midly inflamed sites with 5-6 mm probing depths (r = 0.0003, p = 0.999), but significant relationships among moderately inflamed sites with 5-6 mm depths (r = 0.567, p = 0.027) and 7-11 mm depths (r = 0.639, p = 0.010). Thus polyamines may be involved in subgingival plaque homeostasis at moderately inflamed periodontal sites.
