title: Effect of an herbal mouth rinse in preventing periodontal inflammation in an experimental gingivitis model: a pilot study.
abstract: BACKGROUND
  Gingivitis is a chronic inflammatory condition, resulting from gingival bacteria and bacterial byproducts. Antiplaque oral rinses reduce inflammation by removing or inhibiting plaque formation. The purpose of this pilot study was to examine the anti-inflammatory effects of HM-302, a mouth rinse based on natural products, on gingival inflammation.
  
  
  METHODS
  A prospective, double-blinded, randomized parallel-group controlled trial involving 62 patients was conducted to assess efficacy and safety. During a 2-week period with no dental hygiene, subjects were randomized to receive either the study rinse (HM-302); a cetylpyridinium chloride (CPC) rinse; an essential oils (EO) rinse; or a water-only preparation. The gingival index (GI), plaque index (PI), and number of bleeding sites were measured at baseline and at the end of the study period.
  
  
  RESULTS
  Progression of gingival inflammation resulting from lack of dental hygiene was lowest in patients treated with the HM-302 rinse, and was significantly less marked than in patients treated with the water-only preparation. When compared to the CPC and EO treatments, HM-302 was the only mouth rinse that was significantlybetter than the control, with respect to both the change in absolute GI scores (p = .006) and to the percent increase in GI scores (p = .012). No serious adverse effects were noted in any of the study groups.
  
  
  CONCLUSIONS
  HM-302 is a safe and effective treatment for preventing the development of gingival inflammation in an experimental gingivitis model. Further research is needed to evaluate its long-term effects.
