摘要
目的:体外研究氟保护漆Duraphat对碳酸饮料引起恒牙釉质脱矿后再矿化的影响及作用。方法:选择12~25岁因正畸减数拔除的前磨牙30颗,制备釉质切片,分为A组(可口可乐)、B组(去离子水)、C组(可口可乐+Duraphat)、D组(可口可乐+2%Na F)、E组(可口可乐+人工唾液)(n=15),进行为期7 d的相应处理。扫描电镜观察恒牙釉质表面形态变化,X线能谱分析釉质表面的钙、磷水平变化。结果:扫描电镜显示A组釉质表面粗糙,呈蜂窝状外观,B组釉质表面平坦,C组釉质表面见大面积沉积物,D组釉质表面见细小的沉积物,E组釉质表面见少许沉积物。钙、磷水平A组低于B组、C组高于E组(P<0.05)。钙水平D组高于E组(P<0.05)。结论:碳酸饮料处理对恒牙釉质具有脱矿作用;氟保护漆Duraphat可促进碳酸饮料引起恒牙釉质脱矿的再矿化。
Objective： To study Duraphat fluoride varnish on the remineralization of demineralized permanent enamel by carbonated beverages. Methods： 30 permanent premolar teeth from 12 to 25 years old young people were collected from orthodontic extraction. Enamel blocks were prepared from each tooth and randomly divided into group A （Coco cola） , B（ deionized water）, C（ Coco cola ＋ Duraphat）, D（ Coco cola ＋2% NaF） and E（ Coco cola ＋ artificial saliva）（n = 15）, the specinens were respectively treated for 7 d. The enamel surface were observed by scanning electron microscope（SEM）. The Ca2＋ and p3＋ content（ weight percentage） were detec- ted by energy spectrum analyzer. Results： The surface of permanent enamel of group A showed a characteristic honeycomb-like ap- pearance, that of group B were smooth. Group C showed irregular large globule deposits on the surface, group D showed some globule structures on the surface, group E showed a little deposits on the surface. Ca2 ＋ and p3 ＋ content of group A was lower than that of group B, in group C was higher than in group E（P 〈 0.05 ）. Ca2＋ content in group D was higher than that in group E（P 〈 0.05）. Conclu- sion： Duraphat fluoride varnish can promote the remineralization of demineralized permanent enamel by carbonated beverage.
