Dynamics of nitrite and nitrate levels (μmol/mL) in plasma (a) and crevicular periodontal fluid (b). The experimental group (Exp, n = 39) was treated with conventional periodontal treatment plus topical daily application of fermented papaya gel into gingival pockets; the control group (Ctr, n = 45) received conventional periodontal treatment for the same period of time. Healthy donors: n = 25. Values are represented as mean and standard deviation (SD). ^# P < 0.05 versus analogous day of treatment in the control group; ^∗ P < 0.05 versus healthy donors.
