Abstract
Objective To investigate the related factors of enamel demineralization after orthodontic treatment of labial side fixation and the clinical efficacy of infiltration resin in the treatment of enamel demineralization. Methods The clinical data of 150 patients treated with orthodontic treatment of labial side fixation from January 2014 to May 2015 in our hospital were analyzed retrospectively. According to the occurrence of enamel demineralization after treatment, the patients were divided into demineralization group and non-demineralizing group, and there were 64 cases in the demineralization group, and there were 86 cases in the non-demineralizing group. The risk factors of enamel demineralizationwere analyzed by single factor descriptive analysis and multivariate Logistic linear regression. In addition, 64 patients with enamel demineralization were randomly divided into fluoride group (fluoride treatment) and infiltration resin group (infiltration resin therapy), and there were 32 cases in each group, and the clinical efficacy and cosmetic effect of the two groups were compared and analyzed. Results There was no significant difference of the rate of enamel demineralization between male and female patients after orthodontic treatment of labial side fixation (P >0.05), but the rates of enamel demineralization of the patients age ≤ 18 years, the times of treatment >16 months, brushing frequencies ≤3 times / d, without the use of fluoride toothpaste and with bad eating habitswere significantly higher than those of the patients age >18 years, the times of treatment≤16 months, brushing frequencies>3 times / d, the use of fluoride toothpaste and without bad eating habits (P <0.05),and the OR values of the age≤18years,the times of treatment>16 months, brushing frequencies ≤ 3times / d, without the use of fluoride toothpaste and with bad eating habits were respectively 2.37, 3.26, 4.35, 2.19 and 2.58, whichwerethe risk factors for enamel demineralization (P <0.05). The total effective rate of the infiltration resin group was 96.88%, which was significantly higher than 81.25% of the fluoride group (P<0.05). The excellent and good rate of cosmetic result of the infiltration resin group was was 96.88%, which was significantly higher than 81.25% of the fluoride group (P <0.05). Conclusion The occurrence of enamel demineralization after orthodontic treatment of labial side fixation is significantly related to the age of patients, the course of treatment, frequency of tooth brushing, the type of toothpaste and the bad eating habits, which are the risk factors of occurrence of enamel demineralization, and there are theobvious clinical effect and better cosmetic effect that the treatment of enamel demineralization by infiltration resin.关键词
