A recently discovered alloy of cobalt and samarium (CO5Sm) has exceptional magnetic properties. A laboratory evaluation was made of the grip force of samples of this alloy of a size suitable for dental use. A review of both dental and general literature points to the need for establishing, prior to widespread usage, that magnetic fields are harmless to surrounding tissues.
最近发现的一种钴和钐的合金（CO5Sm）具有特殊的磁性。对这种尺寸适合牙科使用的合金样品的夹持力进行了实验室评估。对牙科和一般文献的回顾表明，在广泛使用之前，有必要确定磁场对周围组织无害。
