A. Tooth Preparation :

Prepare the tooth in the usual manner. For pulp capping, use calcium hydroxide paste. 2. Clean the prepared tooth with pumice and water. 3. Rinse thoroughly with water. Remove excess moisture by blotting with a cotton pellet or gently blowing with an oil free air. DO NOT DESICCATE. Prepared surfaces should appear moist (glistering).
B. Restoration Preparation :

Make sure that the restoration is pretreated and handled according to the manufacturer’s instructions.
C. Powder and Liquid Dispensing :

The standard powder to liquid ratio is 0.19/0.12 (1level scoop of powder to 2 drops of liquid.)
For accurate dispensing of powder, lightly tap the bottle against the hand. Do not shake or invert.
Hold the liquid bottle vertically and squeeze gently.
Close the bottle immediately after use.
D. Mixing :

Dispense Powder and Liquid into the pad. Using the plastic spatula add all the powder to the liquid. Mix rapidly for 45-60 seconds.
NOTE : When mixing larger amounts, divide the powder into two equal parts. Mix the first portion with all of the liquid for 15 seconds. Incorporate the remaining portion & mix the whole thoroughly for 45 seconds (Total 60 seconds).

E. Applications : Immediately apply (within 1 minute after dispensing) to the surfaces to be coated using a micro applicators, DO NOT AIR BLOW.

NOTE : Should the coated surfaces be contaminated with water, blood or saliva, wash and dry the surface and repeat the coating procedure.

F. Cementation:

1) Coat the internal surface of the restoration with sufficient cement and seat immediately. The working time is 2 minutes from the start of mixing at 23±1°C (73.40±1°F). Higher temperatures shorten working time. 2) Maintain Moderate pressure. 3) Start removing excess cement when it feels rubbery. 4) Finishing can be started 4 minutes 30 seconds after seating the restoration.
