Immediate Dentin Sealing (IDS) - Reliable Adhesion Starts Immediately After Preparation

Immediate Dentin Sealing (IDS) is a clinically established technique where dentin is sealed immediately after tooth preparation, before impression or provisionalization. Scientific evidence shows that bonding to freshly cut dentin significantly improves adhesion compared to delayed dentin sealing, while also reducing bacterial leakage and postoperative sensitivity.

On this page, Kerr Professional Education brings together practical insights and real-world perspectives on IDS.

Two Clinically Proven IDS Workflows

IDS is based on one key principle: Fresh dentin provides the optimal substrate for hybrid layer formation and long-term bond durability. Over time, two IDS workflows have proven to be clinically reliable.

Conventional IDS (Etch-and-Rinse Approach)

Maximum control and long-term evidence

Workflow
• Etch dentin with phosphoric acid
• Apply multi-step adhesive
• Light cure → sealed dentin surface

Clinical Case

Immediate Dentin Sealing in Daily Practice

In this detailed clinical case, Dr. Didier Dietschi demonstrates how Immediate Dentin Sealing can be integrated into indirect restorative workflows, supporting predictable and long-term clinical outcomes.

Simplified workflow with enhanced sealing

Workflow
• Apply universal adhesive
• Cover with thin layer of flowable composite
• Light cure → reinforced sealed dentin

Choosing the Right Approach – Supporting Immediate Dentin Sealing with Proven Adhesive Solutions

Conventional IDS

When the clinical priority is maximum bond strength and control, the recommended approach is Conventional IDS. It is best for clinicians who want maximum control of the adhesive interface and proven long‑term performance.

IDS with Resin Coating

When the clinical priority is efficiency and a simplified protocol, the recommended approach is IDS with Resin Coating. It is best for clinicians looking for a more efficient workflow with strong sealing performance.

Why this works
Multi‑step etch‑and‑rinse systems remain the reference for dentin bonding, ensuring deep resin infiltration and a stable hybrid layer. Clinical studies show improved bond strength and marginal integrity compared to delayed dentin sealing.

Why this works
The addition of a low‑viscosity resin layer enhances dentin sealing and protects the hybrid layer. Evidence indicates improved interface integrity and long‑term restoration performance.
