Ch4 bases, liners, and intracoronal
temporaries Questions with Detailed
Verified Answers
bases and liners
Ans: these are used to protect the pulp or to aid in its recovery, or both
pulpitis
Ans: inflammation of the pulp is called
caries
traumatic occlusion
effects of the cutting bur
desiccation
chemical irritation from restorative material
temperature change
dimensional change
lack of marginal seal
Ans: what are the 9 possible causes of pulpitis?
water or airwater spray coolant
, Page | 2
Ans: what must be used with the high speed instruments to minimize the
traumatic effects of the cutting burs?
dessication
Ans: a strong stream of air directed at dentin that can injure the pulp is
called
dentinal tubules
Ans: pulpal irritants from the chemicals in the restorative material can
seep through what part of the tooth and contact the pulp?
coefficient of thermal conductivity
Ans: different materials have different rates of conducting heat which can
be measured as the..
poor
Ans: enamel and dentin are what type of conductors of heat?
high
Ans: amalgam and metal alloy have a relatively _____ coefficient of
thermal conductivity.
lower
, Page | 3
Ans: composite resin has a ______ coefficient of thermal conductivity than
enamel and dentin and do not pose a potential problem for thermal
irritation.
sealers or liners
Ans: these function to seal off the cavity prep, and are used in very thin
layers
1-seal off cut dentinal tubules (preventing chemical irritation to the pulp, and
amalgam from discoloring the tooth)
2- seal off microscopic space between tooth surface and restoration (reducing
leakage)
3- can NOT provide thermal insulation (too thin)
Ans: 3 basic functions of sealers/liners
sealers or liners
Ans: this material can help prevent postoperative sensitivity by reducing
the infiltration or leakage of fluids and saliva at the margins of the new
restoration
cavity varnish
Ans: this type of sealer is composed of natural/synthetic resins dissolved
into an organic volatile solvent
