# The wetting of an adherent surface by an adhesive is related to: (AIPG-01)

# The wetting of an adherent surface by an adhesive is related to:
(AIPG-01)
A. Surface texture of the adherent
B. Surface energy of the adherent
C. Nature of the adherent that is crystalline or amorphous
D. Surface tension of the adherent

The correct answer is B. Surface energy of the adherent.

The property of wetting and adhesions are directly related to surface energy of adhesives. Substances with low surface energy like teflon are often used to prevent the adhesion of films to a surface. Metals because of their high surface energy, interact vigorouslywith liquid adhesives.

The surface energy of many restorative materials is higher when compared to that of tooth. So, there is greater tendency for the surface and margins of restorations to accumulate debris. This property will explain the relatively high incidence of marginal caries seen around dental restorations.
