摘要
目的:研究使用固定矫正器治疗后,牙釉质脱质矿好发牙齿、好发部位与发生率情况。方法:对非治疗组67个患者2072个牙齿及治疗组100个患者2156个牙齿进行临床观察。结果:非治疗组脱矿发生率6.17%、治疗组16.23%(P<0.01),好发牙齿是上前牙及下颌第一恒磨牙;好发部位:牙颈部与托槽周围。结论:固定矫正器引发的牙釉质脱矿问题,十分值得关注,并需采取相关措施进行干预。
Objective:To study theincidence of enamel demineralization and the most susceptible teeth and area to demineralization after orthodontic with fixed appliance. Methods : Eighty - seven patients (2072theeth) were included into the untreated group and with the treated group, which consisted of 100 patients (2156te - eth). Results: The incidence of demineralization the treated group wasl6.23% ( P 〈 0. 01 ). The most susceptible teeth to demineralization were maxillary incisors and mandibular first molar. The most susceptible area was dental cervix and that surrounding the bracket. Conclusion:The results suggested that preventive programs should be considered to avoid demineralization during the orthodontic treatment with fixed appliance.
