contradictions to using composite:
Give this one a try later!
Restoration will have heavy occlusal stresses
Submarginal areas that can't be isolated or finished
Costly, time and technique sensitive
components of smear layer
Give this one a try later!
made up of loosely bonded gel-like mixture of organic and inorganic
dentinal cutting debris, salivary proteins, intra-oral bacteria and plaque
debris (hydroxyapatite crystals and partially denatured collagen)
, forced into dentinal tubules forming amorphous plugs (can by removed by
etch)
top reasons for post op sensitivity:
Give this one a try later!
Over-etching dentin/ Over-drying dentin
Solvents not removed during drying step (audio test)
Incomplete material coverage
Under curing (importance of lights)
Polymerization shrinkage and stress
you should make a mental noteof what two things before the tooth is prepped?
Give this one a try later!
1.occlusion
2.width/depth of prep in order to identify flash while finishing
how to apply bond:
Give this one a try later!
, first margins of prep then inside cavity prep
macrofills are usually used for what type of restorations?
Give this one a try later!
posterior
options to isolate the tooth with while placing restoration:
Give this one a try later!
1. rubber dam
2.cotton rolls
3. retraction cord
role of adhesives:
Give this one a try later!
Direct bonding of composite restorations
Bonding of crowns using resin based cements
Application of post and core materials
