Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To assess the anti-inflammatory effect of a poly herbal mouthwash in periodontal patients after 3-month use and to compare it with placebo.
The mouthwash dose administered was 1ml diluted in a measuring cup (15ml) of water twice daily, for 1 minute
Participants adherence to the intervention was monitored by mouthwash bottle returns.
Intervention code [1] 301650 0
Treatment: Other
Comparator / control treatment
Control group: patients using placebo mouthwash
Test group: patients using herbal mouthwash
Placebo mouthwash was prepared using 2 ml of glycerin (sweetening agent), cinnamon and vanilla flavoring agents, and brown food coloring, dissolved in 1 liter of distilled water and placed in 100 ml brown-colored opaque bottles marked only with number’s patient.
Control group
Placebo

Outcomes
Primary outcome [1] 306464 0
Differences in mean reduction of inflammation index.
Inflammation was measured by recording the bleeding index FMBS (Full Mouth Bleeding Score) on 6 dental surfaces of all teeth, using periodontal probes, according to the criteria of Ainamo and Bay (1975).
Timepoint [1] 306464 0
Baseline and 3 months post-intervention commencement
Primary outcome [2] 306465 0
Mouthwash safety was assessed using a questionnaire (specifically designed for this study) in which patients reported any adverse events, including redness of oral mucosa, mouth burning, desquamation, oral dryness, hard tissues brown spots, alteration of taste.

Secondary outcome [1] 348625 0
Difference in mean change of plaque accumulation index.
This was assessed using plaque index FMPS (Full Mouth Plaque Score), using plaque detectors, according to the criteria of O’Leary (1967).

Statistical methods / analysis
Sample size calculation was made according to previous studies (Mehta et al. 2013; Aspalli et al. 2014; Pradeep et al. 2016). The expected mean bleeding score at the end of the follow-up was evaluated to be reduced in the experimental group compared to the control (placebo) group. Using an unpaired t-test and assuming an alpha error of 0.05 and an expected withdrawal/dropout rate of 10%, a minimum of 20 participants per group were requested.
Mann-Whitney and Wilcoxon tests will be used to evaluate the data.

Summary
Brief summary
Numerous studies on anti-plaque and anti-gingivitis agents provided strong evidence in favor of the use of antimicrobial agents such as mouthwashes as adjuncts to mechanical plaque control. Recently, essential oils containing mouthwashes have been demonstrated to be effective in reducing dental plaque and gingival inflammation. The present study was aimed to evaluate, after 3 months, the efficacy a newly-developed herbal mouthwash in patients suffering from moderate periodontal disease and to compare its efficacy to a placebo mouthwash.
