What is the mechanical interface between tooth and adhesive called?

Dentin layer
Hybrid layer
Adhesive layer
Composite layer

The correct answer is: Hybrid layer

The mechanical interface between the tooth and adhesive is known as the hybrid layer. This layer is formed when the adhesive resin infiltrates and tags into the demineralized dentin, creating a micromechanical bond between the tooth structure and the restorative material. The hybrid layer plays a crucial role in ensuring the retention and longevity of the restoration. Option A (Dentin layer) is incorrect because the dentin layer refers to the underlying dentin tissue of the tooth, not the interface with the adhesive. Option C (Adhesive layer) is incorrect because the adhesive layer refers to the layer of adhesive resin that bonds the tooth structure and the restorative material together, not the mechanical interface between the tooth and adhesive. Option D (Composite layer) is incorrect because the composite layer refers to the layer of dental composite material used for the restoration, not the interface between the tooth and adhesive.
