铝（Al）的吸收，渗透深度，并保留在健全和酸蚀牙釉质的测定后，在体外应用的解决方案，含有0.005 M或0.037 M铝。与对照组相比，大量的铝吸收（约2000至6000 ppm）检测到在健全和酸蚀牙釉质，有显着更多的铝沉积在后者。对处理过的釉质的连续层的分析表明，Al主要位于表面釉质的前20 μm内。只有轻微的减少铝保留发生后一周的水浸泡或一分钟的刷洗用水或牙膏，表明铝是牢固地结合釉质。
The uptake, depth of penetration, and retention of aluminum (Al) in sound and acid-etched dental enamel were determined following in vitro applications of solutions containing 0.005 M or 0.037 M Al. Compared with controls, significant amounts of Al uptake (approximately 2000 to 6000 ppm) were detected in both sound and etched enamel, with significantly more Al deposited in the latter. Analysis of successive layers of treated enamel demonstrated that Al was located predominately within the first 20 μm of surface enamel. Only slight reductions in Al retention occurred following one week of water-soaking or one minute of brushing with water or dentifrice, indicating that Al was firmly bound by enamel.
