Specification: Type: Light-curing composite resin Shade: A1, A2, A3 Net weight: 2.5 g Color: As shown in picture Quantity: 1 pc Features: 1. Low polymerization shrinkage 2. High strength and polishability 3. Modulus of elasticity similar to dentin 4. Radioopaque and fluoride-releasing; optimal polishability and high shade stability 5. Easy to mold 6. Good adhesion to orthodontic brackets 7. Simple and convenient to use 8. Suitable for all types of cavity preparations Usage: 1. Prepare cavities according to standard procedures, remove carious tissue, and clean the cavity. 2. Apply dental etchant to the tooth surface to be bonded, rinse thoroughly, and air-dry. 3. Apply a uniform, thin layer of dental adhesive to the bonding surface, then light-cure for 20 seconds using a dental curing light. 4. Fill and shape with an appropriate amount of composite resin. Cure with a light source of minimum intensity 400 mW/cm² for 20 seconds. Curing depth: 1.5 mm. For deeper restorations, extend irradiation time or use incremental layering technique. 5. Trim and polish the restoration. Check occlusion using articulating paper before final polishing. Use rubber polishing wheels and ultra-fine abrasive polishing strips for best results. 6. When indicated, use pulp capping or lining materials such as calcium hydroxide (light-cured or self-cured) or other non-oil-based liners. Avoid eugenol-containing materials as a base. Scope of application: Non-occlusal cavity restorations Attention: Close the cap immediately after use to prevent light exposure. Contraindications: Not recommended for direct pulp capping. In cases of pulp exposure or proximity to the pulp chamber, perform appropriate pulp capping or protective procedures prior to restoration. Treat active pulp disease before placement. Storage conditions: Store at room temperature, away from direct sunlight.
