Class I cavities Flashcards
what are buccal and occlusal pits and fissures known as?
stagnation areas
why are occlusal caries difficult to detect?
surface often remains intact- but bacteria enters deepest part of fissure and rapidly spreads along ADJ so must always be treated- OCCULT CARIES (hidden)
how are occlusal caries detected?
radiographs
when do you restore occlusal caries?
always as rapid spread- cavitated or infected dentine
what treatment options are there for occlusal cavities?
sealant restoration
conventional restoration
what material can be used for occlusal caries?
composite as less destructive
when would you do a sealant restoration?
if minimal and only part of fissure system involved
when would you do a conventional restoration?
if large- and majority of fissure system involved
how do you do a sealant restoration?
la
dental dam
outline form- minimal
remove caries- adj first then base
debridement
etch prime bond
place composite in increments only touching one wall of cavity
cure
etch and dry fissure system
place sealant and cure
check occlusion and POI
how do you do a convention occlusal restoration?
la
dam
outline form- minimal
remove caries- adj then base
debridement of cavity
line if needed
etch prime bond
place oblique increments no more than 2mm and cure
finish
check occlusion and POI
