Application
1. Tooth Preparation
Clean the cavity preparation with pumice and water. Rinse thoroughly and dry, but do not desiccate.
By using a cotton pellet apply a dentin conditioner for 20 sec to remove the smear layer. Rinse the dentin conditioner with water and dry it in an air stream, but do not desiccate.
Pulp capping with Oxford GI CEM is contraindicated. To deep areas of possible pulpal exposure apply a small amount of calcium hydroxide.
Prepare the carefully cleaned restoration according to the instructions of the manufacturer.

2. Mixing
The powder/liquid ratio to achieve a suitable consistency is 1,8 /1.0. This can be obtained by mixing one level (blue) scoop of powder and two drops of liquid.
For accurate dispensing of Oxford GI CEM Powder shake the bottle to loosen the powder. Overfill the spoon with the powder, level the powder by using the collar at the top of the bottle and
carry it onto the mixing pad.

Avoid compressing powder into the spoon with the inside wall of the bottle.
For dispensing of Oxford GI CEM Liquid turn the bottle vertically with the tip about 5cm above the mixing pad. Steady your hand and squeeze the bottle gently to dispense the drops. If any
bubbles are present, lightly tap the bottle with the fingers holding it. Discount drops that contain bubbles and are obviously not full-sized.
Use a small spatula to rapidly mix all the cement powder into the liquid. Usually one scoop powder/ 2 drops liquid should provide for sufficient amount of mixed cement. The mixed cement should
be thixotropic and have a smooth consistency and glossy appearance. Total mixing time is 30 sec.
After use, tightly close both liquid and powder bottles to prevent exposure to moisture.

3. Cementing
Apply the mixed cement to the prepared bonding surface of the restoration and seat immediately (working time 1:25 min from start of mixing at 23°C). Net Setting time is approx. 4:30 min.
Remove excess cement at the first setting stage.
