The mean BOP scores at baseline (BOP-0) in the intervention and placebo groups were 0.78 and 0.79, respectively, but this difference was not statistically significant (p = 0.999). The mean BOP at four weeks (BOP-3) were 0.59 and 0.69 in the intervention and placebo groups, respectively, in which this difference was not statistically significant (p = 0.085). According to the results of the Friedman test, during the study time, the changes in BOP score had a statistically significant decreasing trend in both groups (p = 0.001) (Table
