Abstract:

Objective    Study of fixed orthodontic treatment of enamel demineralization of related risk factors and treatment methods，for clinical provides the basis. Methods    February 2014 to 2016 years 3 months in the hospital for treatment of orthodontic fixed appliance treatment in patients with 116 cases，carries on the analysis to the treatment of patients with associated risk factors by self-made questionnaire，using SPSS 18.0 software to carry on the single factor and multi factor non conditional logistic regression analysis，analyzing of fixed orthodontic treatment of enamel demineralization related risk factors. Results    Fixed orthodontic treatment of enamel demineralization incidence rate and the gender difference was not statistically significant（P > 0.05）；fixed orthodontic treatment of enamel demineralization rate and age，orthodontic treatment，frequency of tooth brushing，containing fluoride toothpaste，eating sweets and drinking carbonated drinks relationship closely（P < 0.05）；fixed orthodontic treatment of enamel demineralization of non conditional logistic analysis showed that the fixed orthodontic treatment of enamel demineralization had a rate with age，poor diet and brushing and orthodontic treatment relationship closely（P < 0.05）. Conclusion    Fixed orthodontic treatment of enamel demineralization of many risk factors，should be based on risk factors to take active and effective measures to deal with and improve the clinical cure rate.
