Total-Etch vs. Self-Etch Adhesives

Total-etch adhesives require careful ________ to prevent over-etching.

Self-etch adhesives are classified into mild, moderate, or (a)   based on their aggressiveness.

Total-etch adhesives are known to create a ________ surface on enamel, enhancing mechanical retention.

• Smooth

• Porous

• Rough

• Glossy

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

• Stronger bond to dentin

• Reduced risk of enamel demineralization

• Simpler application technique

• Higher bond strength to enamel

Self-etch adhesives reduce the incidence of ________ due to their minimal impact on enamel.

• Marginal discoloration

• Composite wear

• Bonding failures

• Microleakage

Total-etch adhesives require a separate step to:

• Prime enamel

• Etch dentin

• Rinse after application

• Apply a desensitizer

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

• Require fewer bonding steps

• Do not require enamel etching

• Have a lower viscosity

• Provide a stronger bond to dentin

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

• Acid concentration

• Water content

• Application time

• Surface roughness

Total-etch adhesives primarily rely on ________ to etch enamel and dentin.

• Phosphoric acid

• Hydroxyapatite

• Ethanol

• Sodium fluoride

Total-etch adhesives are known for achieving:

• Stronger bond to dentin

• Less technique sensitivity

• Simpler application procedure

• Reduced risk of post-operative sensitivity
