Preventive Resin Restoration Flashcards
alternative procedure for restoring young permanent teeth
preventive resin restoration
minimal tooth prep for caries removal but have adjacent susceptible fissures
preventive resin restoration
removing only carious tooth structure in small class I cavities
preventive resin restoration
types of PRR
- Type A
- Type B
- Type C
PRR Type:
suspicious P and F where caries removal is limited to enamel
Type A
PRR Type:
unfilled resin/sealant
Type A
PRR Type:
incipient lesion in dentin that is small and continued
Type B
PRR Type:
mixture of sealant and filled resin
Type B
PRR Type:
characterized by the need for greater exploratory prep in dentin; larger than other types
Type C
PRR Type:
unfilled followed by filled resin
Type C
essential in removing carious dentin
adequate access to underlying dentin
does not need to be removed if access and vision are clear
unsupported enamel
cross section shape of removing carious dentin for PRR
tear drop shaped
used to obtain access to questionable fissures
high speed diamond bur
used to remove deeper dentinal caries
low speed round bur
seconds for light curing GIC liner
40 seconds
where to place GIC liner
over dentin, extending up to DEJ
why it is not necessary to etch GIC liner
sufficient roughening of GIC results from the washing process
occurs when excess resin is applied
- produce pooling
- reduce integrity of bond
kind of resin sealant used over restoration
opaque unfilled fissure sealant
seconds for curing resin sealant
20 seconds
