The existence of hitherto unsuspected micropores in fissure sealant films (bis-glycidyl methacrylate resin films) has been demonstrated by means of scanning electron microscopy. Immersion of specimens in various ionic solutions showed that the defects in the surface of the resin film tended to become filled with the passage of time.
通过扫描电子显微镜已证实,在窝沟封闭剂薄膜(双甲基丙烯酸缩水甘油酯树脂薄膜)中存在迄今未被发现的微孔。将标本浸泡在各种离子溶液中表明,随着时间的推移,树脂薄膜表面的缺陷往往会被填满。
