Chapter 43: Restorative and
Esthetic Dental Materials
Recall
1. A brand-new dental material is evaluated by what professional organization?
-The American Dental Association's Council on Dental Materials, Instruments, and Equipment is
a subcommittee that collaborates with federal agencies to evaluate new dental materials to ensure
that businesses adhere to regulations and standards.
2. When there is distortion, what kind of reaction does a dental material go through?
A dental material experiences stress when it experiences distortion.
3. What happens when a dental material is heated or cooled?
The dental material expands and contracts at its own rate as temperature changes occur.
4. Where does galvanic action originate?
The salt in our saliva, which is a good conductor of electricity, and the interaction between two
different kinds of metals, which acts as a battery and releases an electrical current, are the
sources of galvanic action.
5. When using a dental material, what are the four properties that must be taken into
account?
Flow, adhesion, retention, and curing are the four application properties that must be taken into
account when applying a dental material.
6. How does a material that is auto-cured set up or harden?
-The combination of various materials makes an auto-cured material hard.
, 7. Which metals make up the amalgam powder?
Tin, silver, copper, and zinc are the metals that make up the powder that makes up the alloy in
amalgam.
8. Could dental mixture be put in foremost or back teeth?
The strength of amalgam makes it ideal for the chewing force exerted by the posterior teeth,
despite the fact that it is not used in the anterior teeth for aesthetic reasons.
9. What advantages does copper bring to amalgam restoration?
-Corrosion resistance and strength are provided by copper in amalgam restoration.
10. Where are amalgam scraps disposed of?
-Scraps of amalgam are disposed of in a plastic container containing water until the container is
full and the appropriate agency arrives to take it.
11. In what way is the amalgam triturated?
When the alloy powders are mixed in the amalgamator, the amalgam is triturated, resulting in the
mass used to restore the tooth.
12. How long would Sybraloy be triturated?
At a setting of medium, I would triturate Sybraloy for 13 seconds.
13. Dimethacrylate is commonly referred to as what?
Dimethacrylate is frequently referred to as resin matrix.
14. For posterior restorations, which type of filler of composite resin is most commonly
used and is the strongest?
The macrofilled composite is the strongest composite resin and is typically used for the posterior.
