氟化物在预防正畸脱矿中的应用

Application of fluoride in the prevention of orthodontic demineralization

目的:探讨氟化物在预防正畸脱矿中的应用效果。方法:2009年3月-2011年12月收治错畸形患者90例,所有患者在治疗前后记录牙齿脱矿的部位、牙位及程度。治疗方法均采用直丝弓矫治技术治疗,矫治时间13~27个月,平均18.9个月,在矫正过程中让患者每天用含氟牙膏刷牙。结果:本组90例患者经过治疗后,发生牙齿脱矿370颗,其中上颌牙齿发生脱矿212颗(9.8%),其中上颌侧切牙58颗,上颌中切牙42颗,上颌尖牙40颗,上颌第一前磨牙22颗,上颌第二前磨牙24颗,上颌第一磨牙26颗;下颌牙齿发生脱矿158颗(7.3%),其中下颌侧切牙36颗,下颌中切牙20颗,下颌尖牙34颗,下颌第一前磨牙26颗,下颌第二前磨牙16颗,下颌第一磨牙26颗。治疗前发生牙齿脱矿16例(17.8%),牙齿脱矿颗数130颗(6.0%),经过矫正后,牙齿脱矿44例(48.9%),牙齿脱矿颗数共370颗(17.1%),其中1级282颗,2级88颗。结论:在口腔正畸治疗过程中牙釉质脱矿应该引起重视,要采取必要的措施进行预防。

Objective:To explore the application effect of fluoride in the prevention of orthodontic.Methods:50 cases with malocclusion were selected from March 2009 to December 2011.The tooth demineralization parts,tooth position and degree of all the patients were recorded before and after treatment.The therapeutic method was straight arch wire technique treatment.The treatment time was 13~27 months,and the average was 18.9 months.The patients used fluoride toothpaste every day in the correction process.Results:90 cases of this group after treatment,370 teeth occurred demineralization.212 teeth(9.8%) were maxillary teeth,among 58 teeth were maxillary lateral incisors,42 teeth were maxillary central incisor,40 teeth were maxillary canine,22 teeth were maxillary first premolars,24 teeth were maxillary second premolars,26 teeth were maxillary first molar.158 teeth(7.3%) were mandibular teeth,among 36 teeth were mandibular lateral incisor,20 teeth were mandibular central incisor,34 teeth were mandibular canine,26 teeth were mandibular first premolar,16 teeth were mandibular second premolar,26 teeth were mandibular first molar.Before treatment,16 cases(17.8%) occurred tooth demineralization,the number of tooth demineralization was 130(6%).After correction,44 cases(48.9%) occurred tooth demineralization,the number of tooth demineralization was 370(17.1%) among 282 teeth were 1 grade,88 teeth were 2 grade.Conclusion:We should pay important attention to enamel demineralization in the course of orthodontic treatment.We should take the necessary measures to prevent.
