How long do you have to leave biodentine on?

You need to leave Biodentine on for a minimum of 15 minutes to allow it to harden properly.

Biodentine is a advanced biocompatible dentin substitute widely used in restorative dentistry. After its application in a dental cavity or for pulp protection, a specific waiting period is essential for the material to fully set and achieve its necessary properties before further steps can be taken.

Optimal Hardening Time for Biodentine

The critical waiting time for Biodentine to harden before proceeding with subsequent dental procedures, such as the adhesion of a final composite layer, is at least 15 minutes. This duration ensures the material transitions from its mixed state to a stable, hardened structure.

Why the 15-Minute Wait is Crucial

Adhering to this minimum hardening time is vital for the success and longevity of the dental restoration. Here’s why:

• Material Setting: The 15 minutes allow the internal chemical reactions of Biodentine to complete, ensuring it achieves its final set and mechanical strength.
• Structural Integrity: Proper hardening contributes to the material's high compressive strength and stability, making it a reliable foundation for subsequent restorative materials.
• Enhanced Adhesion: Waiting the recommended time prevents premature manipulation or stress on the material, which could compromise its bond to the tooth structure and to the overlying restorative materials.
• Procedural Efficiency: While it involves a waiting period, this step is crucial for preventing potential complications, debonding, or material failure, ultimately leading to a more efficient and successful overall treatment.

Practical Considerations for Biodentine Application

When incorporating Biodentine into your restorative workflow, keep these practical points in mind:

• Application Thickness: Biodentine can be applied in a single bulk fill, often leaving sufficient space (e.g., 1.5 mm) from the occlusal surface for the final layer of composite enamel.
• Workflow Integration: Plan your procedure to comfortably accommodate the 15-minute hardening time. This might involve preparing other instruments or attending to another patient during this period.
• Undisturbed Setting: Ensure the applied Biodentine is kept dry and undisturbed during its setting phase to allow for optimal hardening.

By allowing Biodentine to set for at least 15 minutes, dental professionals ensure its optimal performance, providing a strong, durable, and biocompatible base for long-lasting dental restorations.
