In another RCT, mouth rinse containing stevia or placebo was used daily by children for 6 months.At the end of the trial, there was a significant improvement in the stevia arm compared with theplacebo arm in plaque scores (P = 0.03) and gingival scores (P = 0.01). There were no changes inthe number of cavitated lesions in the stevia arm, but there was an increase in cavitated lesionsin the placebo arm (from 5.6% to 5.8%) (210).
