This document is not applicable to dental amalgam alloy powder and dental mercury supplied in a pre-capsulated form.

This document is not applicable to other metallic materials in which an alloy powder reacts with an alloy that is liquid at ambient temperature to produce a solid metallic material intended for dental restoration.

This document applies to products used to make dental amalgam restorations, supplied to the user in the following forms: dental amalgam alloy as a fine free flowing powder, or as a fine powder compacted into tablets and dental mercury in dental mercury sachets (sometimes referred to as dental mercury pillows). The mass of dental mercury in these sachets is limited to the amount required to make a small to medium-sized restoration in a single tooth.
