what are poor thermal conductors
enamel
dentin
the thicker the material the more
viscous
tarnish can be reversed through polishing while corrosion is irreversible
true
is an important property requirement of impression and restorative materials
diminensional stability
how much heat and cold are transmitted to pulpal and soft tissues under a restoration
thermal conductivity
bonding is also known as
luting
class five material, the strongest least soluble dental luting cements which are adhesive release fl.
glass inomoner ally c and b sealents
seals dentin tubules, not used with composite material, will interfere with adension
varnish
cements are used for cementation of restorations and as bases and commonly composed of — —- or glass powder and have an acidic liquid or eugenol

polishing considerations
avoid pulpal trauma by using slow speed light intermitten pressure and adequate water coolant
