Questions with Correct Answers 100% Verified By Experts| 2025/2026 Latest Update
bases and liners these are used to protect the pulp or to aid in its recovery, or both
pulpitis 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 what are the 9 possible causes of pulpitis?
water or airwater spray coolant what must be used with the high speed instruments to
minimize the traumatic effects of the cutting burs?
dessication a strong stream of air directed at dentin that can injure the pulp is called
dentinal tubules 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 different materials have different rates of conducting
heat which can be measured as the..
poor enamel and dentin are what type of conductors of heat?
, high amalgam and metal alloy have a relatively _____ coefficient of thermal conductivity.
lower 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 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) 3 basic functions of sealers/liners
sealers or liners 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 this type of sealer is composed of natural/synthetic resins dissolved into an
organic volatile solvent
varnish Copalite is an example of this type of material
varnish this material is soluble in the oral cavity and will dissolve in time near the
cavosurface
resin cements more recently, this type of material is used as linterss in preparations more
commonly than varnish
with a microbrush cavity varnish is applied to the prepared tooth using what?
