Specifications 1. **Type**: Light-cured composite resin 2. **Color models**: A1, A2, A3 3. **Net weight**: 2.5 grams 4. **Color**: As shown in the picture 5. **Quantity**: 1 piece Features 1. Low polymerization shrinkage. 2. High strength and good polishability. 3. Similar elastic modulus to dentin. 4. Radiopaque and able to release fluoride, with the best polishability and high color stability. 5. Easy to shape. 6. Easy to bond with orthodontic brackets. 7. Simple and convenient to use. 8. Suitable for all types of cavity preparations. Usage methods 1. Prepare the cavity according to conventional requirements, remove the decayed material, and clean the cavity. 2. Apply the dental composite resin pretreatment agent (etchant) on the tooth surface to be bonded, rinse and dry the bonding surface. 3. Apply a thin and even layer of the dental composite resin pretreatment agent (bonding agent) on the bonding surface, and irradiate it 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 400 milliwatts per square centimeter. Irradiate it with a light source for 20 seconds to cure it. The curing depth is 1.5 millimeters. If the filling depth is large, the irradiation time can be appropriately extended or stratified curing filling can be carried out. 5. Trim and polish. Check with articulating paper before trimming. It is recommended to use a rubber polishing wheel and an ultra-fine abrasive polishing strip. 6. Recommended pulp protection and base materials: Calcium hydroxide (light-cured or chemically cured) or other non-oily base materials. Do not directly use materials containing eugenol as the base. Scope of application Non-occlusal cavity filling and restoration. Precautions Immediately close the cap tightly after use and avoid light. Contraindications Use with caution for pulpitis. When the pulp is exposed or close to the pulp chamber, pulp capping and pulp protection surgery must be performed before using resin filling. Other pulp diseases should be treated before filling. Storage conditions Store at room temperature and avoid direct sunlight.
