RELIGHT

ReLight – universal and easy-to-use set for restoration

INSTRUCTION FOR USE
RELIGHT
Universal Light-curing Restorative Composite
- Dimethacrylate oligomers (bis-GMA, TEGDMA, UDMA, bis-EMA, PEGDMA) - Combined radiopaque filler from modified aluminosilicate glass (0.02-2.0 μm) - Nanosized particles of silicon oxide (5-20 nm)
The proportion of inorganic filler is approximately 80%.

PROPERTIES
Universal restorative material RELIGHT is a hybrid radiopaque light-cured composite. Composite can be easily shaped, does not stick to the instrument, cured under 400-500 nm wavelengths light and polished to a “dry” shine. Material RELIGHT has fluorescence, color stability and radiopacity. In order to simulate dental tissues, material is produced in a wide range of VITA shades and has three levels of opacity.
Universal light-curing restorative composite RELIGHT is intended for use in aggressive biological medium at a temperature range from 32°C to 42°C (in oral cavity at the temperature of (37±1)°C and humidity of 60-90%).

INDICATIONS
Scope – dentistry.

Universal light-curing restorative composite RELIGHT is designed for:

- restoration of all cavity classes according to Black;
- core Build-ups;
- splinting;
- correction of composite restorations;
- fabrication of indirect restorations (inlays, onlays, veneers).

CONTRAINDICATIONS
Individual intolerance.
Apply carefully to patients with allergy to methacrylates.

SIDE EFFECTS
As far as all terms of storing, transporting and application are observed, there are no other side effects.

METHOD OF USE
Material, stored at low temperatures, should be warmed at room temperature within 1 hour before use. Universal shades

PREPARATION
Before restoration, dental tissues should be cleaned with non-fluoride paste.

SELECTION OF SHADE
When selecting the shade of restoration material, the surface of restored tooth should be cleaned and moisturized. The intensity of the color of restorative material depends on its thickness.
Suitable shades are determined at daylight or artificial light with the help of VITA scale assuming the thickness of intended restoration.

RECOMMENDATIONS
To test the material of selected shade apply it on untreated surface of the tooth. Make a pattern with the thickness of intended restoration and do polymerization. Estimate the compliance of the shade with tooth colour under different lights, then remove material from the surface of the tooth. If necessary, the procedure can be redone until matching the shade.
Attention! In case of accidental contact with oral mucosa, eyes or skin, rinse the affected area with large amount of water.

ISOLATION
To ensure good adhesion of material, tooth surface must be thoroughly dried and prepared. For isolation can be used rubber dam or cotton rolls and saliva ejector.

CAVITY PREPARATION
Cavity is prepared according to the general rules of adhesive technology. It is necessary to round the corners, appeared during preparation. In case of deep cavity, for pulp capping apply calcium hydroxide material and isolate it with glass ionomer cement.
Attention! Do not use eugenol-containing materials, because eugenol disrupts the composite's structuring.
ADHESIVE APPLICATION
Prepared tooth surface should be treated with etching gel based on 37% phosphoric acid (gel for etching TRAVLIN, “TehnoDent” Co. Ltd). Gel is applied first on the enamel surface, and after 5-10 seconds on the dentin surface. In 15-20 seconds gel should be washed out with water. Dry the surface with compressed air. In case of saliva contact with etching gel or dried tooth surface, repeat etching procedure, then rinse and dry the surface.
Attention! In order to avoid bad adhesion of composite to dental tissues, water for washing should not contain impurities. Air for drying must not contain any oil or water vapor.
Bonding agent RELIGHT is applied with 2-3 coats on the prepared surface of the tooth by gently rubbing for 15 seconds. Then gently dry adhesive with air for 5-10 seconds for solvents evaporation. Do photopolymerization with 400-500nm wavelengths light for 20 seconds.

APPLICATION OF COMPOSITE AND CURING
Composite material RELIGHT should be applied and cured layer by layer to reduce shrinkage of the material.
Time of curing and thickness of the layer is determined by transparency of material.
