conventional sealant technique窝沟杯刷清洗封闭术
1.Methods A total of 240 first permanent molars in 60 patients aged from 6 to 10 years were treated with light cure Estiseal LC in occlusal pit and fissure enameloplasty sealant technique(EST),The opposite permanent teeth treated with light cure Estiseal LC in occlusal pit and fissure conventional sealant technique(CST) were employed as the controls.结果随诊3年后发现Estiseal LC光固化窝沟封闭树脂用于窝沟釉质成形封闭术与窝沟杯刷清洗封闭术组术后1、2、3年时均有显著性差异(P<0。

窝沟封闭剂分子式：CAS号：性质：封闭牙齿颌面上的窝洞、裂隙所用的材料。有化学固化和光固化两大类：前者为双组分包装，一由双酚A-甲基丙烯酸缩水甘油酯、活性稀释剂和过氧化苯甲酰组成；另一组分是含有机胺及活性稀释剂的双酚A-甲基丙烯酸缩水甘油酯。使用时将两组分充分混合，涂于应用部位，在口腔内聚合固化。后者为单组分，是甲基丙烯酸甲酯单体稀释的双酚A-甲基丙烯酸缩水甘油酯；其激活剂是在有机胺中加入二酮，在可见光下聚合固化。它们在固化前流动性好，容易渗入窝洞或酸蚀过的釉质面。固化后形成“树脂突”固位，可阻止细菌及食物残渣进入窝沟，能有效地防止窝沟龋发生。
