BASES, LINERS, AND INTRACORONAL
TEMPORARIES 90 QUESTIONS & CORRECT
ANSWERS LATEST 2025
bases and liners - ANSWER-these are used to protect the pulp or to aid in its
recovery, or both
pulpitis - ANSWER-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 - ANSWER-what are the 9 possible causes of pulpitis?
water or airwater spray coolant - ANSWER-what must be used with the high
speed instruments to minimize the traumatic effects of the cutting burs?
, dessication - ANSWER-a strong stream of air directed at dentin that can injure the
pulp is called
dentinal tubules - ANSWER-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 - ANSWER-different materials have different
rates of conducting heat which can be measured as the..
poor - ANSWER-enamel and dentin are what type of conductors of heat?
high - ANSWER-amalgam and metal alloy have a relatively _____ coefficient of
thermal conductivity.
lower - ANSWER-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 - ANSWER-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) - ANSWER-3 basic functions of
sealers/liners
