Abstract:

To investigate the effect of Coptis decoction on gingivitis in fixed orthodontic treatment. Methods100 patients aged 11 to 19 were randomly divided into experimental group (50 patients) and control group (50 patients). The experimental group was treated with Coptis decoction besides normal oral health measures, while the control group was treated with 0.9% N.S besides normal oral health measures. Changes of GI (gingival index) and PLD (plaque index) in the second premolar and first molar of the two groups were measured before and after the treatment. Results4 weeks after the fixed appliance was placed, GI and PLI were increased in both groups, but there was no significant difference between the two groups, however 8 weeks and 12 weeks later, GI and PLI in the two groups showed significant differences (P＜0.05). ConclusionCoptis decoction can efficiently reduce the incidence of gingivitis in fixed orthodontic treatment.

Key words: Coptis decoction； Fixed orthodontics； Gingivitis
