Self-Etch Adhesives Quiz

Self-etch adhesives are classified based on their pH levels. A self-etch adhesive with a pH around ___________ is considered mild.

Self-etch adhesives are designed to simultaneously:

• Etch enamel and dentin

• Etch only enamel

• Prime dentin only

• Prime enamel only

The bond strength of self-etch adhesives is primarily influenced by:

• Acid concentration

• Water content

• Application time

• Surface roughness

One challenge with self-etch adhesives is:

• Inconsistent bond strength to dentin

• High technique sensitivity

• Difficulty in controlling the etching process

• Limited availability of compatible restorative materials

Which component in self-etch adhesives is responsible for both etching and priming?

• Phosphoric acid

• Hydroxyethyl methacrylate (HEMA)

• Benzalkonium chloride

• MDP (10-Methacryloyloxydecyl dihydrogen phosphate)

One advantage of using self-etch adhesives over total-etch adhesives is:

• Stronger bond to dentin

• Simplified application procedure

• Less risk of enamel demineralization

• Longer working time

The application technique for self-etch adhesives typically involves:

• Etching enamel, rinsing, and then priming dentin

• Applying a single layer onto both enamel and dentin simultaneously

• Conditioning enamel with phosphoric acid before applying the adhesive

• Using a separate etching agent for dentin before applying the adhesive

Self-etch adhesives are suitable for bonding:

• Only to enamel

• Only to dentin

• Primarily to enamel with minimal dentin bonding

• Both to enamel and dentin

The hybrid layer formed by self-etch adhesives consists of:

• Unreacted resin monomers and a thin layer of demineralized dentin

• Etched enamel and a layer of primed dentin

• Bonding agent and acid-etched enamel

• Amorphous calcium phosphate and resin tags

Self-etch adhesives are less technique-sensitive compared to total-etch adhesives primarily because they:

• Require fewer bonding steps

• Do not require enamel etching

• Have a lower viscosity

• Provide a stronger bond to dentin
