摘要
Purpose: The purpose of this study was to assess the effects of fixed orthodontic treatment duration on DMFT (D: decay, F: filling and M: missing teeth) index and white spot lesion (WSL) formation. Materials and Methods: Eighty four patients (45 females and 39 males, 13-18 years old, mean age: 14.7 +/- 0.8) who were undergoing fixed orthodontic treatment were invited to participate in this study. All patients were treated with a 0.018 inch slot MBT fixed orthodontic appliances. An examiner used the Gorelick index for assessment of white spot lesion (WSL) on the buccal surface of teeth before (T1) and after (T2) treatment. The World Health Organization (WHO) criteria were utilized to diagnose the carious status (DMFT) of the subjects. Subjects were divided into three groups according to treatment durations (Group A: 0-18 months, Group B: between 18-30 months and Group C: more than 30 months). Results: The prevalence of WSL was 15.4% at T1 in all groups. After treatment (T2), 69% of patients presented WSL. The incidence of patients who developed at least one new WSL during fixed orthodontic treatment was 53.6%. The greatest prevalence of WSLs was found in the mandibular first molars (20.6%), followed by the maxillary lateral incisors (16.3%) and the mandibular second premolars (13.7%). There were significant differences in the prevalence of WSLs (p<0.01) and DMFT index (p<0.01) between Group C and other two groups (Group A and Group B). Conclusion: The results showed that patients whose orthodontic treatment was longer than 30 months are at higher risk for white spot formation and DMFT index. White spot lesion formation should be prevented with caries preventive applications and effective oral care support in these patients.
