Figure 2. The mean percent (± standard error of the mean) tryptase+ and c-kit+ mast cells in (A) the lesions of healthy/gingivitis (n = 22) and periodontitis (n = 31) subjects; (B) healthy/gingivitis tissues placed into 3 groups on the basis of size of infiltrate ("small", n = 9; "medium", n = 7; "large", n = 6); and (C) periodontitis lesions placed into 3 groups on the basis of size of infiltrate ("small", n = 8; "medium", n = 12; "large", n = 11).

Figure 3. The mean percent (± standard error of the mean) IgG2+ and IgG4+ B-cells/plasma cells in (A) the lesions of healthy/gingivitis (n = 21) and periodontitis (n = 29) subjects; (B) healthy/gingivitis tissues placed into 3 groups on the basis of size of infiltrate ("small", n = 9; "medium", n = 6; "large", n = 6); and (C) periodontitis lesions placed into 3 groups on the basis of size of infiltrate ("small", n = 7; "medium", n = 12; "large", n = 10).
