Temporary seals - what they are made?

Applied in cases where the treatment of caries and its complications is not complete in one visit. Some of these materials are also used as a bandage to cover medicines and as insulating pads under permanent seal.
Requirements for the materials: to be malleable, easily introduced into the cavity and the implications, do not inactivate the drug substance does not dissolve in the oral fluid, to ensure hermeticism for the requisite period (not less than 2 weeks).

Zinc sulfate cements.
Artificial dentin. The powder consists of zinc sulfate and zinc oxide in a 3:1 ratio and 5-10% kaolin. Gets mixed in distilled water.
Methods. Isolate the tooth from saliva, dry cavity.
On the glass separately applied a few drops of distilled water and Noah powder. In separate portions of the powder is added to the water and quickly stir with a spatula until the consistency of sour cream. Rapidly injected into the cavity and seal with a cotton swab. Hardens within 2-3 minutes.

Dentin-paste – dentin, thrown into the mix the essential oils (sage, clove oil, eugenol, etc.). It is a homogenous mass of white with grayish-yellow or light pink tinge to the smell of the oil.
Produced in finished form. Dentin-paste injected into the cavity and seal with a cotton swab. Hardens during 1,5-2 hours.
The material is plastic, has good adhesion, water repellent, ie, requires careful drying. But you can not be used for isolation of liquid drugs and dentin-paste can not be right to impose a permanent seal.

Vinoksol – consists of zinc oxide powder and liquid (a solution of polystyrene in guaiacol). It has good adhesion, antiseptic activity, etc. – still filling up to 6 months.
Methods. Kneaded on the glass in the ratio of 9.10 drops of liquid to 1 part powder to the paste-like consistency for 30 seconds., Hardens within 3-4 hours in the oral cavity.

Zinc evgenolovye cements.
Cement based on zinc oxide and oil of cloves or eugenol. It has good adhesion, antiseptic and analgesic properties, is resistant to chewing loads and effects of saliva, stimulates substitution dentin.
Methods. On the glass causing a few drops of oil and zinc oxide powder that is mixed to paste-like consistency. The more powder is added, the thicker the pasta and stronger seal. Hardens in the mouth after 8-12 hours.

Kariosan. Available in the complete powder-liquid. Basis fluid – eugenol. Powder (zinc oxide with synthetic resins, accelerators, inert substances) 2 species: pulvis Rapid and pulvis Normal. Pulvis Rapid (Accelerated) is used for medicinal pads and temporary fillings. Pulvis Normal for sealing root canals.

Polikarboksilatnye cements.
Polikarboksilatny cement (Whitebark. Modern filling material, belongs to a class of polymeric sealing materials based on polyacrylic acid. Production kit powder-liquid. In vial powder consisting of zinc oxide with the addition of magnesium oxide. The drip liquid – 37% aqueous solution polyacrylic acid. The material is able to chemically bind with enamel and dentin, has good adhesion, is plastic, does not irritate the pulp, is resistant to moisture.
Polikarboksilatny cement can be used not only for the temporary seals and gaskets, but also for sealing of deciduous teeth, filling the channels on indications for prosthetic fixation.

Methods of mixing. On the glass deals 1 meter of powder and 2 drops of liquid. Knead quickly (no more than 20-30 seconds), quickly making the cavity. Hardens during 1,5-2 min. The appearance of filaments indicates the unsuitability of the portions and the need for mixing the material again.
Temporary fillings are removed from the cavity excavator or rotating boron.
