【摘要】：目的:研究氟保护漆应用于乳牙釉质表面对酸性含乳饮料致离体乳牙釉质脱矿的抑制作用,阐明氟保护漆的抗脱矿作用,为氟保护漆的临床推广及婴幼儿群防提供实验室依据。方法:将预备好的30个无龋、无明显裂纹及釉质发育缺陷的乳牙唇侧釉质块随机分为人工唾液A组(对照组)、B组(酸性含乳饮料组)、C组(0.1%氟保护漆组),每组10个标本。C组标本之釉质表面用小毛刷均匀涂布氟保护漆2次,自然晾干45 min。A组置于37℃恒温的10 mL人工唾液中浸泡4 d。B、C 2组在37℃恒温水箱中浸泡于10 mL酸性含乳饮料中,浸泡2 min,取出1 min,再浸泡,共9 min。3次/d,共4 d。3组牙釉质制作标本,应用场发射扫描电镜和能谱分析仪,检测乳牙釉质的表面形态变化,Ca2+、P3+含量数值(重量百分比)及Ca2+、P3+比值,采用SPSS 11.5软件包对数据进行统计学分析。结果:酸性含乳饮料浸泡可致乳牙釉质Ca2+、P3+含量显著降低(P0.01)。氟保护漆处理后的釉质Ca2+、P3+含量降低程度显著低于酸性含乳饮料浸泡组(P0.01)。结论:酸性含乳饮料对乳牙釉质表面有较强的酸蚀脱矿作用。釉质表面应用氟保护漆可增加硬度,在一定程度上抑制乳牙釉质在酸性含乳饮料中的脱矿,但不能完全抵御饮料的酸蚀。
[Abstract]:Objective: to study the inhibitory effect of fluorine protective paint applied on enamel surface of primary tooth on demineralization of isolated primary enamel induced by acidic milk drink, and to elucidate the anti-demineralization effect of fluorine protective paint, and to provide laboratory basis for clinical application of fluoride protective paint and prevention of infant and young children. Methods: 30 caries free of caries were prepared. The labial enamel masses of deciduous teeth without obvious cracks and enamel development defects were randomly divided into artificial saliva group A (control group, group B) (acidic milk beverage group, group C, 0. 1% fluorine protective paint group), each group of 10 specimens with small enamel surface. Brush evenly coated with fluorine protective paint 2 times, The natural drying 45 min.A group was immersed in 10 mL artificial saliva at 37 鈩，
