WEEK 1 - 4 STUDY GUIDES FROM TEACHER| COMPLETE A
GUIDE| LATEST UPDATE
1. intimate contact with living tissues is known as? ANS biomaterials
2. biomaterials used in or around the oral cavity is known as? ANS dent
materials
3. why do we study dental materials? (4) ANS 1) safety-handling, disposal,
patient safety
2) maintenance-cleaning, polishing, instrumentation
3) delivery-behavior of material, manipulation of material, assisting in the delivery
of the material
4) patient education- options of material choices, maintenance
4. how many FDA classes is there in dental materials? ANS 3
5. this FDA class is considered the lowest risk. it involves good manufacturing
standards and record keeping practices. ei) gloves, prophy paste, OTC prod-
ucts ANS FDA class I
6. this FDA class is when products required to meet performance standards
set by FDA or ADA ei) amalgam restoration (silver filling), composite restora-
tion (tooth colored restoration) ANS FDA class II

, 7. this FDA class is the most regulated devices which support or sustain
human life. it requires FDA approval to ensure safety and effectiveness. ei)
implants, bone grafting material ANS FDA class III
8. this is an approach to oral health care that requires the judicious integration
of systematic assessments of clinically relevant scientific evidence, relating
to the patients oral medical history, with the dentists clinical expertise and
the patients treatment needs and preferences. this helps the clinician make
decisions on what is relevant to incorporate into practice. ANS evidence-
based dentistry
9. historic materials that were used from ancient times to the 1700's include?
(5) ANS 1) ivory
2) porcelain
3) wax and gypsum
4) zinc oxide-eugenol
5) zinc phosphate
10. most dental treatment consisted of extraction and artificial replacements.
ivory bases were later replaced with wood, human, and animal teeth. Springs
were used for closure of maxillary and mandibular. All of these are historic
materials used during which era? ANS mid 1800's
11. fluoridation was introduced as a means of preventive dentistry in what
year? ANS 1874
12. end of the 'amalgam war' and an acceptable formula for amalgam was
developed by G. B. Black in what year? ANS 1895

, 13. synthetic resins were introduced in what year? ANS 1932
14. during what year was the first community introduced to a fluoridation
program? ANS 1945
15. acid-etch technique was introduced and used today in composite resins
in what year? ANS 1955
16. these 2 agencies represent the standards used to develop specifications
and test at the international level. (2) ANS FDI and ISO
17. this outlines a broad spectrum or requirements that must be met to qualify
for this specific seal. ANS ADA seal
18. materials used to treat disease (sealants, mouthguards, fluoride) are
known as which type of agents? ANS therapeutic agents
19. these materials are used to fabricate and maintain restorations (indirect,
direct, impression materials, gypsum, dental waxes, finishing and polishing
materials) ANS auxiliary materials
20. the property of a material that allows it to not impede or adversely affect
living tissue (materials in the mouth should not exhibit adverse reactions) are
known as? ANS biocompatible
21. materials used to reconstruct tooth structure is known as? ANS
restorative agents
22. this is force applied to compress an object (pushing together) known
as? ANS compressive force
23. this is the force applied when 2 surfaces slide against each other or in a
twisting or rotating motion (slice apart) ANS shearing force
24. this is the force applied in opposite directions to stretch an object (pulls
and stretches) ANS tensile force
