Aluminum is one type of metal base material used as an alternative to acrylic resin. This study evaluated whether commonly used denture cleansers cause leaching of the metal base into the cleaning solution. Seven cleansers (Efferdent, Polident, Clorox, Clorox/Cascade, vinegar, Tartar and Stain Remover, and Ivory soap) and two controls (tap water and distilled water) were evaluated. One hundred thirty-five wax samples (30 x 30 x 1 mm) were cast in 99.4% pure aluminum. The 135 samples were randomly assigned to the nine cleanser groups. Each sample was soaked in a cleanser for 0.5, 1, or 8 hours, and the amount of aluminum present in each cleanser was then analyzed by atomic flame-emission spectrometry. The results indicated that all cleansers leached aluminum into solution in varying amounts. Tartar and Stain Remover and Clorox caused the greatest leaching, whereas Ivory soap and Efferdent leached the least.
铝是一种用作丙烯酸树脂替代品的金属基材。本研究评估了常用的假牙清洁剂是否会导致金属基材溶出到清洁溶液中。评估了七种清洁剂（Efferdent、Polident、高乐氏、高乐氏/佳洁士、醋、牙垢和污渍去除剂以及象牙皂）和两种对照（自来水和蒸馏水）。用99.4%的纯铝铸造了135个蜡样（30×30×1毫米）。将这135个样品随机分配到九个清洁剂组。每个样品在清洁剂中浸泡0.5、1或8小时，然后通过原子火焰发射光谱法分析每种清洁剂中铝的含量。结果表明，所有清洁剂都会将不同量的铝溶出到溶液中。牙垢和污渍去除剂以及高乐氏导致的溶出量最大，而象牙皂和Efferdent的溶出量最少。
