5 Matching Questions

1. matrix
2. exothermic reaction
3. nanofill composites
4. shrinkage
5. monomers

1. a molecules with a functional group
   reactive potion that particpates in polymerization
   C=C
2. b 20 nm
   75-80% filler
   less shrinkage b/c they are pre-shrunk
3. c weaker part
   polymer bis-GMA and diluent
   similar to primers and bonders
   polymerizes to solid that bonds to tooth
   least wear resistant
   will absorb water & may stain or discolor
4. d composites shrink towards center
   may fracture teeth because it pulls on margin as it shrinks
5. e because of C=C being lysed

5 True/False Questions

1. dental acrylic resin polymerization → various shades
   various handling characteristics

   True        False

2. ceramic filler → small particles

   True        False

3. filler + matrix (composite) → combine properties of microfill & hybrid
   strong; very good esthetics

   True        False

4. dr. Raphael Bowen → used when light cannot entirely reach the material
   initiated as light cure then propagates to completion as self-cure
   popular for composite cements

   True        False

5. self cure → thickness of composite that is penetrated by cure light

   True        False
