Immediate Dentin Sealing (IDS) is the process of appropriately conditioning, priming and placing a layer of adhesive on freshly-cut dentin. This is commonly carried out immediately after the tooth is prepared, at the preparation appointment. This seals the dentin and allows time for the dentin bond to fully develop between preparation of the tooth and placement of the final (direct, indirect or semi-(in)direct) restoration.
Advantages of IDS:
- Allows time for the dentin bond to develop and therefore for the hybrid layer to mature in a stress-free environment with less influence from polymerization forces (Decoupling With Time).
- Combats potential issues relating to the Hierarchy of Bondability (HOB).
- In comparison to Delayed Dentin Sealing (DDS), where the dentin bonding is carried out at the same time as the fit of the indirect restoration, IDS increases potential bond strength by 400%.
- Reduces sensitivity in the provisional stage as the tubules are sealed.
- Reduces post-op sensitivity as the hybrid layer is allowed sufficient time to develop.
