Abstract：AIM:To investigate enamel demineralization following orthodontic treatment with fixed appli-ance.METHODS:1 20 patients aged 1 2 ~1 4 years with 2862 teeth after orthodontic treatment with fixed applince and 1 20 age and gender matched controls with 2876 teeth without orthodontic treatment were included.RESULTS:The in-cidence of demineralization of the subjects,after the treatment and the controls was 1 8.3% and 5.3% respectively (P <0.05).There was no difference between sexes in both groups(P >0.05).The most susceptible teeth to deminer-alization were maxillary lateral incisor(34.1 %),maxillary incisor(33.3%)and canine(27.5%),mandible premolar (1 7.4%),mandible lateral incisors(7.5%)and mandible incisors(5.8%).The most susceptible area was dental cervix and that surrounding the bracket.CONCLUSION:There is a significant increase in enamel demineralization after orthodontictreatment with fixed appliance.
