5. Composite is a highly technique sensitive
material
Slight contamination or procedural error
spoils the durability of the restoration
Perfect isolation of operating area is
mandatory
The best isolation is rubber dam .
15. If after cavity preparation the remaining
dentine thickness (RDT) is between 0.5
and 1.5mm a resin modified glass ionomer
(RMGI) base is used. IF RDT is less than
0.5mm a calcium hydroxide liner should be
applied to the deepest aspect of the
preparation then protected with an RMGI
base prior to adhesive placement .
16. It is important to place the composite
incrementally to maximize the polymerization
depth of cure and possibly to reduce the negative
effects of polymerization shrinkage.
Cure each increment for 20 sec.
