temporaries Exam Questions &
Answers (Grade A+)
a strong stream of air directed at dentin that can injure the pulp is
called -
correct answer ✅dessication
pulpal irritants from the chemicals in the restorative material can
seep through what part of the tooth and contact the pulp? -

temporaries Exam Questions &
Answers (Grade A+)
composite resin has a ______ coefficient of thermal conductivity
than enamel and dentin and do not pose a potential problem for
thermal irritation. -
correct answer ✅lower
these function to seal off the cavity prep, and are used in very thin
layers -
correct answer ✅sealers or liners
3 basic functions of sealers/liners -
correct answer ✅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)
this material can help prevent postoperative sensitivity by reducing
the infiltration or leakage of fluids and saliva at the margins of the
new restoration -
