摘　　要：目的 探讨氟化物（氟保护漆、含氟牙膏）的应用对正畸治疗后牙釉质脱矿的影响及预防正畸后牙釉质脱矿的作用。方法 选择在新疆医科大学第五附属医院口腔科接受固定正畸矫治患者60例,均采用直丝弓矫治技术,随机分为3组：对照组20例390颗牙,试验1组20例384颗牙,试验2组20例388颗牙。对照组采取日常口腔护理,不做任何治疗。试验1组采用含氟牙膏刷牙,于每日早、晚各1次,刷牙时间〉3min。试验2组涂布氟保护漆,每半年涂布1次,直至拆除矫治器。所有观察对象在治疗前及正畸治疗后（约2a）拆除正畸部位托槽,计算牙釉质脱矿指数,使用激光龋齿探测仪探测荧光值和对脱矿程度进行评价。结果 对照组390颗牙齿中,正畸治疗后有61颗牙齿脱矿,脱矿率为15.6%;试验1组384颗牙齿中,正畸治疗后有51颗牙齿脱矿,脱矿率为13.3%;试验2组388颗牙齿中,正畸治疗后有37颗牙齿脱矿,脱矿率为9.5%,3组脱矿率差异有统计学意义（χ2=6.452,P=0.040）。试验1组及试验2组治疗后脱矿指数及DD值低于对照组,试验2组低于试验1组,差异有统计学意义（P〈0.05）。对照组脱矿以2度为主（54.1%）,试验1组以1~2度为主（86.3%）,试验2组以1度为主（78.4%）。结论 氟保护漆和含氟牙膏均能起到预防正畸中牙釉质脱矿的作用,以氟保护漆作用更为明显,使用更为方便,患者依从性强,值得临床推广。Objective To investigate the effect of topical application of fluoride on enamel demineralization after orthodontic treatment, compared the role of fluoride toothpaste, fluoride varnish on enamel deminer- alization after orthodontic prevention. Methods In our department, 60 patients with fixed orthodontic ap- pliances were randomly divided into control group and two experimental groups, a total of three groups, each had 20 cases. Control group was taken daily oral care, without any treatment. Experimental group 1 was taken fluoride toothpaste in daily morning and evening. Group 2 was coated with fluoride protection. Calculation of enamel demineralization index, DD examination, evaluation of the degree of carried demi- neralization were observed among three groups. Results In the control group, there were 61 tooth demi- neralization in 390 teeth, with the demineralization rate of 15.6%; in the experimental group 1, there were51 teeth demineralization in 384 teeth, with the demineralization rate of 13.3%; in the experimental group 2, there were 37 teeth demineralization in 388 teeth, with the demineralization rate of 9.5 %, the deminer- alization of three groups was difference was statistically significant （χ2= 6.452, P =0.040）. After treat- ment, demineralization index and DD values of Test group 1 and group 2 were lower than the control group, group 2 was lower than the group 1, the difference was statistically significant （P 〈0.05）. In con- trol group, there were mainly 1 to 2 degrees, accounting for 53.5%; In group 1, there were 0 to 1 de- grees, accounting for 85.1 % ; In group 2, there were 0 degree, accounting for 78.2 %. Conclusion Fluor protector and fluoride toothpaste have a preventive orthodontic enamel demineralization role, and were more effective, more convenient and worthy of promotion.
