A laboratory study was conducted to determine effects of 1.23% APF gel on three composite resins. All composite resins immersed in APF gel lost significantly more weight than did their controls with significantly different weight losses among the APF-treated composites. Surfaces of all resins exposed to APF gel, as viewed in SEM's, exhibited degradation of filler particles.
进行了一项实验室研究，以确定1.23%的含氟防龋凝胶（APF凝胶）对三种复合树脂的影响。所有浸泡在APF凝胶中的复合树脂失重都明显高于其对照，且经APF处理的复合树脂之间的失重存在显著差异。扫描电子显微镜观察显示，所有暴露于APF凝胶的树脂表面均出现填料颗粒降解。
