Universal Light-curing Restorative Composite

INSTRUCTION FOR USE

S-LIGHT

 

Universal Light-curing Restorative Composite

 

COMPOSITION

- Dimethacrylate oligomers (bis-GMA, TEGDMA, UDMA, bis-EMA, PEGDMA);

- Combined radiopaque filler from modified aluminosilicate glass (0.02-2.00 µm);

- Nanosized particles of silicon oxide (5-20 nm).

The proportion of inorganic filler is approximately 80 %.

 

PROPERTIES

Universal restorative material S-LIGHT 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 S-LIGHT 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 shades

А1, А2, А3, А3.5, А4, В1, В2, В3, С2, D3, UD (Universal Dentin), BW (Bleach White)

Shades possess average transparency level between dentine and enamel, which depends on layer thickness. BW shade suits well for milk teeth restoration

Dentine-opaque shades (О)

ОА2, ОА3

Shades used to increase restoration intensity, cover discoloration, prevent through-transmission. Material is applied with layer not more than 0.5 mm

Transparent shades

ТС (Translucent Clear)

Shade used for cutting edge modeling and depth effect

 

INDICATIONS

Universal restorative composite material S-LIGHT is used for:

- restoration of all cavity classes according to Black classification (I-V) on anterior and posterior teeth;

- restoration of tooth stump;

- splinting;

- correction of composite restorations;

- forming of indirect restorations (inlays, onlays, veneers).

 

CONTRAINDICATIONS

Individual intolerance

Apply carefully with patients allergic 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

Attention! Material, stored at low temperatures, should be warmed in room temperature within 1 hour before use

Preparation

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

Selection of shade

During selecting the shade of restoration material, surface of restored tooth should be cleaned and moisturized. The intensity of 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 thickness of intended restoration and do polymerization. Estimate the compliance of shade with tooth color under different lights, then remove material from the surface of the tooth. If necessary, the procedure can be repeated 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 should be thoroughly dried and prepared. For isolation can be used rubber dam or cotton rolls and saliva ejector.

Cavity preparation

Cavity should be prepared according to 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 is applied first on enamel surface, and after 5-10 seconds on 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 material to dental tissues, water for washing should not contain impurities. Air for drying must not contain any oil or water vapor

S-LIGHT Bond is applied with 2 coats on prepared surface of the tooth by gentle rubbing for 15 seconds. Then gently dry adhesive with air within 5-10 seconds for solvents evaporation. Do photopolymerization with light of 400-500 nm wavelengths within 20 seconds.

Application of composite and curing

Composite material S-LIGHT should be applied and cured layer by layer to reduce shrinkage of material.

Time of curing and thickness of the layer is determined by transparency of material:

 

Material transparency

Material layer thickness, mm

Photopolymerization time, s

For LED lamps

(1000-2000 mW/cm2)

For halogen lamps

 (500-1000 mW/cm2)

transparent shade – ТС

2,0

10

20

universal shades

dentine-opaque shades (О)

1,5

20

40

 

Multi-layer method of restoration with different transparency pastes allows to create a highly esthetic restoration.

For toning of a composite restoration it is recommended to use LC colored (white, yellow, grey) composites S-LIGHT colour.

Attention! Composite paste syringe cap must be closed immediately after use. Intense light contact with material at any stage of restoration might cause premature curing.

During curing the waveguide end of the lamp must be kept in close proximity to the curable material. The intensity of the light, emitted by a lamp for photopolymerization, should be regularly tested with the help of suitable photometers.

Fillings treatment

Fillings treatment is carried out after final curing with the help of diamond, hard-alloy burnisher burs, burs or stones. Check the occlusion with articulating paper, remove the excess material with fine-grained diamond bur or stone. For final polishing use polishing discs, silicone heads and finishing polishing paste.

STORAGE

Keep in dry place protected from light at a temperature from 5 °C to 25 °C.

Transport at the temperature range from 5 °C to 25 °C.

Universal light-curing restorative composite S-LIGHT is non-sterile and aimed for multiple use.

Attention! Non-compliance with terms of storage, transportation or application leads to decrease of material life.

After opening of the package, guaranteed storage and service life of the material is limited by an expiration date. Do not use after expiry date.

Shelf life – 3 years.
