New Stetic Nu Alloy Amalgam Capsules — Dispersed Phase · 2 spill · 50 capsules

Copper: alloys are called low-copper, under about 5 percent copper by weight, or high-copper, 6 percent or more. With enough copper, little or none of the weaker phase that corrodes more easily is formed.

Particle shape: the powder is lathe-cut, spherical or a mix of the two. Spherical particles usually give a shorter working time and need less mercury than irregular ones.

Standard: ISO 20749 covers amalgam supplied in capsules pre-dosed with alloy powder and mercury for a single restoration.

The FDA states that the available evidence does not show that mercury from dental amalgam leads to adverse health effects in the general population. It names groups that may be at greater risk: pregnant women, women planning to become pregnant, nursing women and their infants, children, especially those under six, people with neurological disease or impaired kidney function, and people sensitive to mercury or the other metals in amalgam. For those groups the FDA strongly encourages non-amalgam fillings such as composite resins and glass ionomer cements when the dentist considers them appropriate.

The FDA does not recommend removing or replacing amalgam fillings in good condition unless a health care professional considers it medically necessary.
