Select a copper band or clear core form that fits snugly around the cervical area of the tooth. Mix equal amounts of HardCore part A and B until it is uniform color, about 20 seconds.
Place caps on jars immediately after use.
Fill copper band with HardCore or fill core form and place onto tooth. If a transparent form is used, setting can be accelerated by light curing for 40 seconds. Chemical cure continues thereafter until reaction is complete. HardCore chemically cures without the use of a light in 8 minutes from the beginning of mix. If tooth is vital, remove all caries, and in deep cavities, place Pulpdent Cavity Liner on the pulpal floor.
