Dental Light Cure Dentin Bonding Adhesive for Enamel Resin 5ml/Bottle

To help resolve this issue, we would like to verify a few key points that can significantly affect the bonding process:
1. Tooth Surface Moisture Control: After etching and rinsing, the tooth surface should be gently air-dried to a 'moist' state (no visible water droplets). Over-drying can cause the collagen fiber network to collapse, preventing the adhesive from penetrating effectively.
2. Precise Timing: After applying the adhesive, it should be left for 10 seconds before being lightly air-dried for another 5 seconds. This ensures that the solvent evaporates properly, which is crucial for achieving the desired bond strength.
3. Light Curing Conditions: The adhesive must be cured for 20 seconds. It is essential to ensure that the light curing unit has sufficient intensity (recommended 500±50 mW/cm²) and that the light tip is no more than 4 mm away from the tooth surface.
4. Avoid Contamination: If the bonding surface becomes contaminated with saliva or blood, it must be thoroughly rinsed and the adhesive reapplied. Additionally, avoid contact with eugenol-containing materials, as they can severely inhibit the polymerization of the adhesive, leading to bonding failure.

Hopefully, these suggestions will help you use this product more effectively. If you continue to experience issues, we are here to provide further assistance.
