Fig. 2From: Lipoxin A4 levels predict site-specific clinical improvements post scaling and root planing and correlate negatively with periodontal pathogens in severe periodontitisComparison of LXA4 concentrations in GCF between sites that were positive or negative for periodontal pathogens at (A) baseline, (B) 6 months after SRP and (C) the increase in LXA4 concentration between sites that were still populated with presumed microorganisms or not at 6 months after treatment. Significant difference between groups are represented as * (p < 0.05). N, number of sites; P.g, Porphyromonas gingivalis; A.a, Aggregatibacter actinomycetemcomitans; T.d, Treponema denticola; P.i, Prevotella intermedia; T.f, Tannerella forsythiaBack to article page
