Clinical Study of Enamel Demineralization in the Application of Fixed Orthodontic Appliance
SHEN Qiang
Abstract：Objective:To analyze the enamel demineralization incidence and degree of injury in the application process of fixed orthodontic appliance. Method:41 patients with fixed orthodontic appliances for correction were randomly selected in the dental clinic from May 2012 to May 2013 as the observation objects,and the clinical data were retrospectively analyzed in orthodontic treatment,after the end of the overall position of tooth enamel demineralization was summarized,and the enamel demineralization index (EDI) was calculated.Result:24 patients with fixed orthodontic appliance appeared enamel demineralization, the incidence rate was 58.5%.In 946 teeth,112 teeth enamel demineralization occurred,the incidence rate was 11.8%.The enamel enamel incidence of maxillary teeth was 73.2%,which was significantly higher than 26.8%of mandibular teeth,the difference was statistically significant(P<0.05).The average of maxillary tooth enamel demineralization index was significantly higher than that of mandibular teeth,the difference was statistically significant(P<0.05).The demineralization degree was level 1,compared with other degrees,the differences were statistically significant(P<0.05).Conclusion:During the process of the application of fixed orthodontic appliance,the incidence of enamel demineralization is higher,so it should be especially paid attention to the maxillary teeth enamel demineralization treatment and prevention.
