Effectiveness of novel herbal dentifrice in control of plaque, gingivitis, and halitosis - Randomized controlled trial

Background and aim: Plaque is a common etiological factor for common oral conditions like gingivitis, periodontitis, dental caries and halitosis. We aimed to evaluate the efficacy of a novel herbal dentifrice in control of plaque, gingivitis, and halitosis in comparison to control dentifrice. Experimental procedure: We conducted a randomized controlled, single center, double-blinded parallel arm clinical trial. Participants were randomly distributed with commercially available herbal dentifrice or control dentifrice. Assessments of plaque, gingivitis, halitosis, unstimulated saliva pH were done at baseline and at one month by a trained and calibrated periodontist. All the participants were given new toothbrushes one week before the start of the study. They were asked to brush with the designated dentifrices for 2-4 min, twice daily for one month. Results and conclusion: A total of 79 participants were recruited for this study, out of which 75 participants completed the follow-up. Inter-group comparisons of all the variables at baseline showed no significant differences in the mean plaque index, gingival index, halitosis and pH between test and control groups respectively. Intra-group comparisons showed a significant decrease in mean plaque, gingival and halitosis at follow-up than at baseline in both test and control groups. No significant differences between test and control groups were seen in the mean plaque index (P = 0.792), gingival index (P = 0.292), halitosis (P = 0.266), pH (P = 0.742) at follow-up after adjusting the respective baseline scores. The novel herbal dentifrice could be a suitable alternative for the control of plaque, gingivitis, and halitosis. (C) 2019 Center for Food and Biomolecules, National Taiwan University.
