Abstract: Objective: To study the effect of fluoride foam on periodontal index and enamel demineralization for patients with lingual orthodontic treatment. Methods: Thirty patients (600 teeth) with lingual orthodontics from June 2013 to June 2014 were divided into control group (15 cases, 297 teeth) and observation group (15 cases, 293 teeth). The control group accepted routine oral hygiene methods, and the observation group was given 1.23% fluoride foam. After follow-up of 12 months, the enamel demineralization of dental distribution, EDI, PLI and BI were compared between two groups. Results: Enamel demineralization was mainly distributed in the maxillary lateral incisors, maxillary incisors and mandibular premolar. The enamel demineralization rate of observation group was 11.26%, which was significantly lower than that the control group (17.51%, P<0.05). The EDI, PLI, and BI of observation group were significantly lower than those of control group (P<0.05). Conclusion: During lingual orthodontic treatment, the enamel demineralization rate was high. Fluoride foam helps to reduce the enamel demineralization and reduce the periodontal index.
