In a two-year study the adhesion of diluted composite material as fissure sealant was tested upon etched and etched-fluoridated (aminofluoride) occlusal surfaces of molars and premolars. After 24 months the sealant was found to be intact in 89.3% of the only etched and in 85.6% of the etched-fluoridated fissures. 3.9% of all sealed fissures showed either an increase in the degree of caries or a filling, while the control teeth showed a percentage of 49.7 DF. Fissure sealing therefore appears to be an adequate method for reducing occlusal caries.
在一项为期两年的研究中，将稀释的复合材料作为窝沟封闭剂，应用于磨牙和前磨牙经酸蚀及酸蚀-氟化（氨基氟化物）处理的咬合面。24个月后发现，仅经酸蚀的窝沟中，89.3%的封闭剂完好无损；经酸蚀-氟化处理的窝沟中，85.6%的封闭剂完好无损。所有封闭窝沟中有3.9%出现龋损程度加重或进行了充填治疗，而对照牙的龋面均数百分比为49.7。因此，窝沟封闭似乎是一种减少咬合面龋的有效方法。
