N = patient count; N% = percentage of patient count. McNemar's statistical test was used for the comparison of various gingivitis criteria (signs and symptoms) before and after treatment. aNo statistical test was performed since the patient's response was constant between baseline and treatment. bBurning sensation was significantly reduced in patients after treatment (days 14 and 21) compared to baseline, p < 0.05. cNo significant difference was observed between the baseline and THCs treatment, p > 0.05.
