Specification: Type: Light curing composite resin Shade: A1, A2, A3 Net weight: 2.5g Color: As shown in picture Quantity: 1 piece Features: 1. Low polymerization shrinkage 2. High strength and polishability 3. Similar modulus of elasticity to dentin 4. Radiopaque and fluoride releasing 5. Optimal polishability and high shade stability 6. Easy to mold 7. Easy to adhere to bracket for orthodontics 8. Simple and convenient to use 9. Suitable for all types of cavity preparations Usage: 1. Prepare cavities according to standard procedures, remove decayed tissue, and clean the cavity. 2. Apply a dental etchant to the tooth surface to be bonded, rinse thoroughly, and dry the bonding surface. 3. Apply a thin, uniform layer of dental adhesive to the bonding surface and cure for 20 seconds using a dental light curing unit. 4. Fill the cavity with an appropriate amount of composite resin. Cure for 20 seconds with a light intensity of at least 400 mW/cm². Curing depth is 1.5 mm. For deeper fillings, extend curing time or use incremental layering technique. 5. Perform shaping and polishing. Check occlusion with articulating paper before final trimming. Use rubber polishing wheels and fine polishing strips for best results. 6. Use pulp protection materials such as light-cured or chemically cured calcium hydroxide or other non-oily liners. Do not use eugenol-containing materials directly as a base. Indications: Non-occlusal cavity filling and restoration Warnings: Close the cap immediately after use to prevent light exposure. Use with caution in cases of pulp inflammation. For deep cavities approaching or exposing the pulp, perform pulp capping and protective treatment prior to restoration. Treat other pulp conditions before placing the restoration. Storage: Store at room temperature and protect from direct sunlight.
