Composition
urea peroxide (1 g equals 36% H2O2)
Application
PEROXIDON® is intended for whitening non-vital teeth only.
Before the application, the product is mixed with glycerine to paste texture.
How to handle the product
Container with the powder should be strongly shaked up before use, in order to break the powder clods. For measuring off the powder use the spoon attached to the unit package. Remove powder excess using the container's edge.
In order to obtain a paste with a concentration of 6% hydrogen peroxide, this product should be mixed with glycerin in the proportion: 2 spoons of PEROXIDON®/ 1 drop of glycerin.
Bleaching:
- check before bleaching, whether root canal is appropriately obturated with filling material, in case of inappropriate obturation, re-endodontic treatment is necessary;
- remove filling material from the root canal 1-2 mm below the cemento-enamel junction;
- cover root filling material with 0.5-1 mm layer of non-setting calcium hydroxide (e.g. BIOPULP®), and then apply glass-ionomer material. This procedure maintains alkaline pH of the environment, and neutralize possible bleaching material leakage near the neck of the tooth;
- cover thoroughly the bottom and walls of accurately cleaned chamber, with the paste prepared formerly, cover with a cotton swab and then close tightly with cement – pay particular attention to filling leakproofness;
- after 4-5 days, remove temporary filling and rinse the chamber with water. If whitening effect is sufficient, apply calcium hydroxide paste and tightly seal the access opening, otherwise repeat the procedure;
- if the result after triple application of the product is not satisfying, other treatment (e.g. placing dental veneers) should be considered;
- after bleaching completed postpone placing adhesive restorations for 2 weeks. Meanwhile apply calcium hydroxide preparation and then tightly close the access opening with glass-ionomer material;
- afterwards restore missing tissues of tooth.
Description of operation
After application urea peroxide decomposes to urea and hydrogen peroxide. Hydrogen peroxide decomposes then into available oxygen and water. The available oxygen is the active ingredient of the product, which saturates or eliminates chemical bonds, that are responsible for colour of pigment molecules included in teeth.
Storage conditions
Store only in the original packaging, protect from moisture.
Protect from sunlight. Keep out of the reach of children.
