DENTAL MATERIALS SEM II - TEST 1| QUESTIONS
WITH 100% CORRECT ANSWERS 2025
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

2) FDA
3) ADA
4) ISO
8. CHARACTERISTICS OF DENTAL MATERIALS ANS -Biocompatible
-Bond permanently to tooth structures
-Esthetically pleasing
-Useful in repairing and regenerating missing tissues
9. what dental agency was the first to have a seal of acceptance on guidelines
for testing products? ANS ADA - american dental association
10. the ADA seal of acceptance is designed to? ANS help consumers make
informed decisions about the safety and efficiency of products
11. these 2 agencies represent the standards used to develop specifications
and testing at the international level ANS FDI
ISO
12. requirements necessary for a consumer product to qualify for the ADA seal
of acceptance? ANS outlines a broad spectrum or requirements that must be met
to qualify for the ADA seal

, 14. enamel abnormality caused by consumption of excessive levels of fluoride
is known as? ANS fluorosis
15. 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
16. a push, pull or twist (or a combination of these). is also known as? ANS
force
17. the force (weight) applied at the surface will create stress 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
18. examples of force and stress can include? (2) ANS 1) bruxism
2) clenching
19. there is 3 basic types of forces. ANS 1) compressive (pushing together)
2) tensile (pulls and stretches)
3) shearing (slice apart)
20. 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
21. this is force applied at each end of a material in opposite directions to
