Which of the following does NOT affect the success of dentin bonding?

  1. Dentin factors such as sclerosis, tubule morphology, and smear layer

  2. Tooth factors such as attrition, abrasion, and abfraction

  3. Material factors such as compressive and tensile strengths

  4. C-factor considerations

The correct answer is: Material factors such as compressive and tensile strengths

While dentin factors and tooth factors can play a role in the success of dentin bonding, material factors such as compressive and tensile strengths do not affect it. Materials with strong compressive or tensile strengths may actually provide better adhesion to dentin, making them important factors for success. The C-factor, or the ratio of bonded to unbonded surfaces, is also important in achieving effective dentin bonding. Therefore, option C is the only choice that does not affect the success of dentin bonding.
