DHG 212 Quiz #4, Dental Hygiene Program, Academic Year 2026 – Study Guide and Practice
Questions
the act of sticking two things together. In dentistry the term is used frequently to describe the
bonding or cementation process. Chemical adhesion occurs when atoms or molecules of
dissimilar substances bond together. Adhesion differs from cohesion, which attraction among
atoms and molecules of like (similar) materials holds them together - ANS✔✔ adhesion
the bonding of dissimilar materials by the attractive forces of atoms or molecules - ANS✔✔
adhesion
a thick layer of cement used to protect the tooth from chemical and thermal irritation and to
support restorations in deep cavity preparations - ANS✔✔ base
to connect or fasten; to bind. Items are jointed together at their surfaces in three main ways: by
mechanical adhesion (physical interlocking), by chemical adhesion, or by a combination of the
two - ANS✔✔ bond or bonding
A low-viscosity resin that penetrates porosities (voids) and irregularities in the surface of the
tooth or restoration created by acid etching for the purpose of facilitating bonding - ANS✔✔
bonding agent
a thick layer of cement used to replace missing tooth structure in a badly broken-down tooth
and to act as support for a restorative material such as a crown - ANS✔✔ buildup
a thin layer placed on the floor and walls of the preparation to seal the tubules and minimize
microleakage - ANS✔✔ cavity varnish
contact with a substance that interferes with bonding or lessens the chemical or mechanical
properties of the etched surface of the tooth with saliva before bonding - ANS✔✔
contamination
