Is the primer in bonding and etching hydrophobic or hydrophilic?
Understand the Problem
The question is asking whether the primer used in bonding and etching processes exhibits hydrophobic or hydrophilic properties. This is a technical inquiry related to materials science and chemistry, particularly in the context of surface treatments.
Answer
The primer is hydrophilic.
The primer in a bonding and etching system is hydrophilic.
Answer for screen readers
The primer in a bonding and etching system is hydrophilic.
More Information
Primers used in bonding and etching systems are generally composed of hydrophilic monomers. These monomers allow the primer to penetrate and wet the demineralized dentin matrix and collagen network efficiently.
Tips
A common mistake is to assume that because primer is used alongside adhesive resin, it is hydrophobic. However, the primer is actually hydrophilic to bond effectively with the dentin.
