Specification: Type: light curing composite resin Shage: A1 A2 A3 Net weight: 2.5g Color: as picture show Quantity:1pcs Features: 1. Low polymerization shrinkage. 2. High strength and polishability. 3. Similar modulus of elasticity with dentine. 4. Radioopaque and fluoride releasing Optimal polishability and high shade stability. 5. Easy to mold. 6. Easy to adhere to bracket for orthodontics. 7. Simple and convenient to use. 8. Used for all types of cavity preparations. Usage: 1. Prepare cavities according to conventional requirements, remove decayed tissue, and clean cavities. 2. Apply dental composite resin pre-treatment agent (etchant) to the tooth surface to be bonded, rinse and blow dry the bonding surface. 3. Apply a uniform and thin layer of dental composite resin pre-treatment agent (adhesive) on the bonding surface, and illuminate with a dental light curing lamp for 20 seconds. 4. After filling and carving with an appropriate amount of composite resin, the light intensity should not be less than 400mW or cm The light source is irradiated for 20 seconds to solidify. Curing depth 1.5mm. If the filling depth is large, the irradiation time can be appropriately extended or layered solidification filling can be carried out. 5. Conduct trimming and polishing, and inspect with dental bite paper before trimming. It is recommended to use rubber polishing wheels and ultra-fine abrasive polishing strips. 6. Recommended use of pulp protection and cushioning materials: calcium hydroxide (light cured or chemically cured) or other non oily cushioning materials. Do not use materials containing eugenol directly as a base. Scope of application: Non occlusal cavity filling repair. Attention: Close the lid immediately after use to avoid exposure to light. Contraindications: For pulpitis, use with caution. When penetrating the pulp or near the pulp chamber, it is necessary to perform pulp capping and pulp protection surgery before filling with resin. Other pulp diseases should be treated before filling. Storage conditions: Store at room temperature and avoid direct sunlight. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
