Dentsply Prime & Bond NT – Universal Self-Priming Dental Adhesive
Prime & Bond NT is a universal, self-priming dental adhesive designed to bond light-cured composite materials and Dyract compomer to enamel, dentin, metals, and ceramics. It combines primer and adhesive in a single bottle, maintaining excellent bond strength while providing protection against microleakage. When mixed with the Self-Cure Activator, it forms a dual-cure adhesive system suitable for bonding dual- or self-cured composites even in areas inaccessible to light.
Key Features and Benefits:
- Universal Application: Bonds to enamel, dentin, metals, ceramics, and compomer materials.
- All-in-One Formula: Primer and adhesive combined in a single bottle for simplified application.
- Dual-Cure Capability: When mixed with Self-Cure Activator, it bonds dual- or self-cured composites effectively.
- Strong Bond Strength: Provides reliable adhesion with long-term durability.
- Microleakage Protection: Ensures tight sealing of cavity surfaces for reduced sensitivity and enhanced restoration longevity.
Recommended Usage Tips:
For All Types of Restorations:
- Etch dentin for 15 seconds or less to maximize marginal quality and bond strength while avoiding post-operative sensitivity.
- Apply to a moist cavity surface, avoiding overdrying, which can reduce bond strength. Dry briefly with air (1–3 seconds) or blot with cotton.
- Use the adhesive directly from the bottle onto an applicator tip for efficiency and proper solvent concentration.
- Apply ample adhesive to saturate all cavity surfaces; multiple applications may be needed for complete coverage.
- Wait 20 seconds after application, then gently blow air to remove residual solvent, ensuring optimal layering thickness.
For Indirect Restorations:
- Light-curing the adhesive or the Prime & Bond NT/Self-Cure Activator mix improves bond strength.
- Avoid gross pooling; the low film thickness prevents restoration height issues.
- For most indirect procedures using light- or dual-cured luting cements, Prime & Bond NT can be used alone.
- For metallic restorations, light-cure the adhesive applied to the restoration prior to luting for optimal adhesion.
