Riepilogo

The Food and Drug Administration (FDA) is announcing the availability of the guidance entitled "Class II Special Controls Guidance Document: Dental Amalgam, Mercury, and Amalgam Alloy." This guidance document describes a means by which manufacturers of dental amalgam, mercury, and amalgam alloy may comply with special controls that apply to these class II devices. Elsewhere in this issue of the Federal Register, FDA is publishing a final rule to classify dental amalgam into class II (special controls), reclassify dental mercury from class I (general controls) to class II (special controls), and designate a special controls guidance document to support the class II classification of these two devices, as well as the current class II classification of amalgam alloy.
