cavity liners provide a barrier against
irritants from cements and other restorative materials
what do cavity liners stimulate
reparative/tertiary dentin
Do NOT place liners on
cavity walls, cavosurface margins or retentive area
cavity liners do not replace
dentin sealers or varnishes
insulating bases soothes and protects the pulp from
thermal temperatures and irritation from other materials
when applying a cavity varnish you wipe it on
all cavity walls thoroughly
do NOT place varnish; it must not extend
outside the prep; must not extend out to the cavosurface margin
excess cavity varnish must be removed with a
solvent (as main ingredient is resin)
gingival retraction takes place
after the teeth are prepped and before final impression
3 types of retraction
mechanical, chemical, surgical
retraction cords are placed in the sulcus in a
clockwise direction
chemical retraction is left in place for
5-7 minutes
what is used to shrink the tissues in chemical retraction
epinephrine
if pt has heart disease what would you use for chemical retraction
aluminum chloride (10%)
electric pulp testing indicates
whether tooth is vital or non vital
what are the different endodontic vitality tests
palpation percussion thermal cold testing heat testing electronic pulp testing
what factors influence results of vitality tests
teeth w extensive restos
teeth w more than 1 canal
moisture on tooth
the control tooth is tested when
before the tooth in question
You NEVER place electrode on what
metal restoration, wet surface, gingiva or artificial crown
when performing a cold test, teeth with necrotic pulps will or will not respond
will not
cold test uses
dry ice, ethyl chloride (end ice), piece of ice
when heat is applied and pain increases and lasts this may indicate
irreversible pulpitis
sutures are used to
unite parts of the body
examples of absorbable sutures are
chromic/CAT gut
monocryl
vicryl
