Abstract
The frequency of complete penetration of two commercial BIS-GMA resin pit and fissure coating materials into wide and constricted fissures was assessed from photomicrographs. It was found that 334 of the 390 wide fissures examined were completely filled by the coating materials. However, in contrast, only 28 of the 650 constricted fissures examined were completely filled by these resins.
摘要
从显微照片评估了两种市售双酚A缩水甘油醚甲基丙烯酸酯（BIS-GMA）树脂窝沟封闭材料完全渗入宽裂隙和窄裂隙的频率。结果发现，在所检查的390个宽裂隙中，有334个被封闭材料完全填充。然而，相比之下，在所检查的650个窄裂隙中，只有28个被这些树脂完全填充。
