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.
