Restoring Flashcards

endo evaluation
perio evaluation
radiographic evaluation
biological width
root perforation
vertical root fracture
what does percussion test?
periradicular inflammation
what does palpation asess?
mucoperiosteal inflammation
what does a sinus tract imply?
persistent endo infection
what does mobility assess?
loss of connective tissue attachment
how do you assess lesion aetiology?
diagnostic probing
explain the ferrule effect
parallel walls of dentin extending coronally from crown - protective effect, reducing stresses
how high must a ferrule be?
1.5-2mm high
what crown to root ratio is minimally acceptable?
1:1
why would you not place a post in a posterior tooth?
thinner curved roots - higher risk of perforation
how would you restore an anterior tooth with evidence of heavy occlusal forces?
post
how would you restore a posterior tooth with evidence of heavy occlusal forces?
well retained core
what significantly improves the ferrule effect?
preserving as much supragingival tooth tissue as possible
what is a nayyar core?
amalgam core
pros of GI cement and RMGIC?
bonds to dentine
releases fluoride
