Description 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 uniform thin layer of dental adhesive to the bonding surface and cure with a dental light curing unit for 20 seconds. 4. After filling and shaping with an appropriate amount of composite resin, expose to a light source with intensity not less than 400 mW/cm² for 20 seconds to cure. Curing depth is 1.5 mm. For deeper fillings, extend irradiation time or perform incremental layering. 5. Perform trimming and polishing. Use dental articulating paper to check occlusion before final adjustments. It is recommended to use rubber polishing points and ultra-fine abrasive polishing strips. 6. When indicated, use pulp protection materials such as calcium hydroxide (light-cured or chemically cured) or other non-eugenol containing liners. Do not use eugenol-containing materials directly as a base. Scope of application: Non-occlusal cavity restoration Attention: Close the cap immediately after use to prevent exposure to light. Contraindications: Use with caution in cases of pulp inflammation. In cases of pulp exposure or proximity to the pulp chamber, perform pulp capping and protective treatment prior to composite restoration. Other pulp conditions should be treated before restorative procedures. Storage conditions: Store at room temperature and protect from direct sunlight.
