2026 PA EFDA BASES AND LINERS EXAM
WITH CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+
Varnish - ANSWERS-Should not be used under resins as the
solvent in the varnish may react with or soften the resin and
the monomer of the resin may dissolve in the varnish
Resin cements - ANSWERS-Used as liners in preparation
more commonly today then varnishes
Resin cements - ANSWERS-Do not bond as well to deep
Dentin as they do more superficial Dentin, they can cause an
inflammatory response from the pulp or tissues for these
reasons they are not used as the direct pulp capping agents
Copalite - ANSWERS-Cavity varnish that is a sealer used
under amalgam
, Reinforcers - ANSWERS-Are bases used to protect a pulp
from the pressure exerted on it during amalgam
placement/condensation
Reinforcers - ANSWERS-Can be an insulator and in reinforcer
at the same time
Reinforcers - ANSWERS-Can be any material that is placed in
a relatively thick layer between the restorative material and
the Dentin and may be referred as to a base regardless of
the purpose it serves
Insulators - ANSWERS-Also referred to as bases and our
place to insulate the pump from thermal irritation
Zinc Oxide Eugenol (ZOE) - ANSWERS-Used as an insulating
base and reinforcer this is a cement that can be used as a
base under amalgam restoration or as a temporary
restoration
zinc phosphate cement - ANSWERS-Is also used as an
insulator and reinforcer main ingredient of liquid is a
phosphoric acid which can be chemically irritating to the
