  Purpose
Traditional Chinese medicine (TCM) has been seen as the predominant way of treating disease in China over three thousand years. Certain TCM have scientifically proved to have anti-bacterial property. Patients having orthodontic treatment have higher risks of caries and gum diseases. The purpose of this study was to determine whether the use of TCM Mouthrinses in addition to toothbrushing and flossing has an added benefit for orthodontic patients in maintaining proper oral health.

    gingival bleeding index


Secondary Outcome Measures:
  • Salivary cytokines [ Time Frame: 6 months ]
    Salivary inflammatory cytokines (IL-1β and MIF) levels were detected by ELISA assay.

  • Adverse Events [ Time Frame: 6 months ]
    the number of participants with side effects or adverse events were recorded throughout the whole study time.

  • Salivary bacteria counts [ Time Frame: 6 months ]
    Salivary microbial quantifications included total aerobic and anaerobic bacteria, streptococci and lactobacilli counts.

Detailed Description:
The aim of this study was to investigate the effects of a Traditional Chinese medicine (TCM) mouthrinse on gingival health and microbial profiles in orthodontic patients. This six-month randomized, single-blinded, parallel controlled clinical trial consists of 90 patients with fixed appliance treatment. The subjects were allocated to (1) negative-control group: oral hygiene instruction (OHI) alone; (2) positive-control group: OHI plus an EO mouthrinse (Listerine®)(3) test group: OHI plus the TCM mouthrinse (5% Fructus mume extract). Clinical examinations included Plaque Index (PI), Bleeding Index (BI) and Modified Gingival Index (MGI). Salivary microbial quantifications included total aerobic and anaerobic bacteria, Streptococci and Lactobacilli counts. Clinical and microbiological examinations were conducted at baseline, 3 and 6 months (T1, T2 and T3).
