DMG TECO

• 1 x 5ml Bottle.

Interactions with other materials

Do not use together with substances which inhibit polymerization. This is especially valid for products which contain eugenol, such as temporary cements.

Instructions for use :-

• Light-curing units should have an output of 450 nm and should be checked regularly.
• The light intensity should be a minimum of 400 mW/cm2.
• Place the light as close as possible to the material.
• Observe the manufacturer’s instructions for the light unit.
• Ensure that the etched or bonded surface does not become recontaminated prior to each subsequent working step.
• Do not remove the oxygen inhibition layer caused by the application because this is important for the bonding process with the material applied on top.
• It is essential to use etching gel on the affected enamel and dentine surfaces.
• Due to the fact that excess material may collect between the tooth and matrix (pooling effect), if possible use a matrix only after the bond has been applied.
• Observe the manufacturer’s instructions for any other materials that are used with TECO.

Recommended Use

1. Prepare the cavity in accordance with the general rules for adhesive procedures. Bevel the enamel edges. Note: The use of a rubber dam is recommended.

2. In deep cavities in areas close to pulp, provide protection in the form of a suitable liner, e.g. by using a small quantity of calcium hydroxide and a thin layer of glass ionomer cement.

3. Etch enamel and dentine with 37 % phosphoric acid gel (e.g. DMG Etching Gel). Start the etching process with the enamel and then expand this to the dentine, if applicable, so that the response time on the enamel is 20 to 60 seconds, while the response time on the dentine does not exceed 15 seconds. Observe the manufacturer’s instructions.

Note: When using TECO, it is essential to etch the affected enamel and dentine surfaces.

4. Rinse tooth with water for a minimum of 15 s. Remove general water excess. Note: After the etching process, an even moist layer must remain on the dentine surface requiring treatment. If this is not the case, wet the dentine surface with a moistened micro brush.

5. Work TECO into the tooth structure generously for 20 seconds using the brush.

6. Remove any excess.

7. Blow TECO using oil-free air into a thin, even layer until the surface appears evenly moist (approx. 5 s).

8. Light-cure TECO for 10 seconds with a suitable light unit.

9. Use the filling material or dental cement according to manufacturer’s instructions and cure with a light-curing unit. Observe the recommended layer thicknesses and light-curing times.
