摘　　要：目的评价使用自酸蚀粘结剂及Primaflow树脂增强玻璃离子作为窝沟封闭剂的临床效果。方法对1113例6～8岁小学生采取自身双侧对照研究方法，随机选择一侧第一恒磨牙采用Contax粘结剂＋Primaflow进行窝沟封闭；对侧同名牙作为对照组，采用FUJI Ⅶ传统玻璃离子窝沟封闭剂，在第1、2年进行临床观察比较。结果窝沟封闭后2年，Primaflow树脂增强玻璃离子与FUJI Ⅶ玻璃离子窝沟封闭剂的保留率分别为70．80％和49．05％，龋齿发生率分别为6．56％和22．46％。两组封闭剂保留率及患龋率差异均有统计学意义（P〈O．05）。结论使用自酸蚀粘结剂及Primaflow流动复合体能有效地预防窝沟龋的发生，其保留率及防龋能力均优于FUJIVII窝沟封闭剂。Objective To evaluate the clinical effect of self-etching adhesives and Primaflow resin reinforced glass ionomer as the pit and fissure sealants. Methods 1113 6-8 year-old pupils were selected and the self bilateral control study method was used. The first molar of one side was randomly selected to receive Contax hinder ＋ Primaflow for pit and fissure sealing. The first molar on the other side served as the control and received FUJI Ⅶ traditional glass ionomer for pit and fissure sealing. The clinical results were observed and compared in the 1st and 2nd years. Results Two years after the pit and fissure sealing, the retention rates of the Primaflow resin reinforced glass ionomer and FUJI Ⅶ glass ionomer pit and fissure sealants were 70.80% and 49.05% respectively. The retention rates and the caries incidence rates of the two groups were significantly different （P 〈 0.05）. Conclusion Self-etching adhesives and Primaflow flow compound can effectively prevent the occurrence of pit and fissure caries and both its retention rate and caries prevention ability are superior to those of FUJI Ⅶ pit and fissure sealants.
