Figure 2

Elevated alkaline phosphatase (ALP) levels in gingival crevicular fluid of patients with chronic periodontitis. The y-axis represents the median levels of ALP in ng/ml, whereas the x-axis represents various groups of periodontal statuses. H = healthy, G = gingivitis, PG = gingivitis sites in chronic periodontitis, PSL = slight chronic periodontitis sites, PM = moderate chronic periodontitis sites, PSE = severe chronic periodontitis sites. Small open circles and small asterisks are outliers and extremes, respectively. ***p < 0.001.
