Study Notes
Self-Etch Adhesives
- Self-etch adhesives (SEAs) are used for bonding dental materials.
- SEAs dissolve the smear layer, a layer of debris on the tooth surface, as part of the bonding process.
- SEAs can be applied in two ways: two-step or one-step.
Two-Step Application
- The two-step application involves two separate steps.
- The first step combines etching, priming, and bonding.
- The second step involves only bonding.
One-Step Application
- The one-step application combines etching, priming, and bonding into a single step.
- SEAs incorporate acidic components, which simultaneously etch, prime, and bond the tooth surface.
- This eliminates the need for separate etching or rinsing steps.
- The combined process creates a hybrid layer, a strong bond between the adhesive and the tooth.
