COMPLETE SOLUTION RATED A GUIDE
1. shavings from silver cut from coins mixed with mercury was used to form
a silver paste resulting in an? ANS amalgam war
2. in what year did the amalgam war end? ANS 1895
3. an acceptable formula for amalgam was developed in 1895 by? ANS G B
Black
4. why do we study dental materials? (4) ANS 1. Safety
2. Maintenance
3. Delivery
4. Patient Education
5. this is an approach to oral health care that requires the judicious integration
of systematic assessments of clinically relevant scientific evidence, relating
to the patient's oral medical history, with the dentist's clinical expertise and
the patient's treatment needs and preferences. This helps the clinician make
decision on what is relevant to incorporate into practice. What is this known
as? ANS evidence-based dentistry
6. developing an evidence-based approach to addressing client concerns
will? (2) ANS 1) increase the potential for successful client care outcomes by
under- standing the cause and effect relationship between biomaterials and
selected
2) increase the success of the treatment rendered

, 7. agencies responsible for dental standards include? (4) ANS 1) FDI
2) FDA
3) ADA
4) ISO
8. what dental agency was the first to have a seal of acceptance on guidelines
for testing products? ANS ADA - american dental association
9. the ADA seal of acceptance is designed to? ANS help consumers make
informed decisions about the safety and efficiency of products
10. these 2 agencies represent the standards used to develop specifications
and testing at the international level ANS FDI
ISO
11. who is the person who was credited with the discovery of dental fluoro-
sis? ANS Fredrick McKay
12. enamel abnormality caused by consumption of excessive levels of fluoride
is known as? ANS fluorosis
13. dental materials in an oral environment must be? (6) ANS 1) biocompatible
2) durable
3) non reactive in acid/alkaline conditions
4) compatible with other materials
5) esthetically acceptable
6) tolerable to differing temperatures and forces

, 14. a push, pull or twist (or a combination of these). is also known as? ANS
force
15. the force (weight) applied at the surface within the object that tries to resist
the weight. If there is no resistance, the material would be flattened. this is
known as? ANS stress
16. examples of force and stress can include? (2) ANS 1) bruxism
2) clenching
17. there is 3 basic types of forces. ANS 1) compressive (pushing together)
2) tensile (pulls and stretches)
3) shearing (slice apart)
18. this is force applied to compress or squeeze an object (crushing biting
forces). Posterior teeth are ideally suited for this type of force. ANS
compressive force
19. this is force applied at each end of a material in opposite directions to
stretch an object or pull it apart. When this force is applied to a rubber band it
is stretched. ANS tensile force
20. this force is applied when 2 surfaces slide against each other in opposite
directions. When the maxillary and mandibular incisors are used for cutting
this type of force is applied. ANS shearing force
21. this is when force is exerted on a tooth, the tooth or material creates
resistance to counteract the force. Also known as the amount of force exerted
from within an object. ANS stress
22. this is known as distortion or deformation occurring when an object can-
not resist stress. The amount of change that the force has produced. ANS
