Cavity preparation

Isolate the field of operation in a preferred manner. A rubber dam is recommended.
Cavity preparation must provide for the mechanical retention of the product.
If caries are present, completely excavate using low-speed and/or hand instrumentation.
Place matrix and wedge where indicated.
Gently dry preparation with a cotton pellet. Avoid desiccation.
Pulp protection

In deep cavities cover the dentin close to the pulp (less than 1 mm) with a hard setting calcium hydroxide liner (Dycal calcium hydroxide liner, see complete Instructions for Use
Dispensing and mixing

Before dispensing, fluff powder (tumble the powder bottle) to assure uniform bulk density of contents. Fill the measuring scoop to excess without packing.
Level scoop with the bottle insert. Dispense two level scoops of powder onto a clean, non-absorbent mixing pad or glass slab. Larger restorations may require additional scoop(s).
Using the dropper cap, dispense three drops of liquid for two level scoops of powder. After dispensing the liquid, replace the original cap immediately to prevent evaporation and subsequent contamination.
Placement

Mixed material may be carried to the preparation with a suitable placement instrument.  Adapt, contour, and shape with appropriate instruments. Technique Tip: Dipping the instrument into dry powder left on the pad before using to adapt the material will facilitate placement and minimize sticking.
Use as an intermediate restorative material

Trim excess material. Material may be smoothed by lightly burnishing. The initial set occurs approximately 5 minutes from the start of mixing. Increased temperature, humidity, and powder/liquid ratio may accelerate the setting.
Upon set, remove the matrix band if present. Check and adjust occlusion as needed. Additional carving or occlusal adjustment may be accomplished with a round bur. Avoid gouging material with sharp burs at high speed. Additional polishing is not recommended.
Periodically evaluate the intermediate restoration until the final restoration is indicated.  The intermediate restoration should be removed and the final restoration completed within one year of placement.
Use as a protective base

The product is a protective base for non-resin-containing restorative material, such as amalgam or gold.
