DENTAL MATERIALS TEST 1
1. 1800s historical developments of DM
what did most dental treatment consist of in the mid 1800s: Mid 1800's:
-Most dental treatment consisted of extraction and artificial replacements.
-Ivory bases were later replaced with wood and human and animal teeth
-Springs were used for closure of maxillary and mandibular
** didnt have teeth because of infection
2. study of dental materials: science covering the evolution, development, prop-
erties, manipulation, care, and evaluation of materials and in the treatment and
prevention of dental diseases and the interaction of these material with tissues of
the face and mouth
3. the elements of EBD evidence based dentistry: scientific evidence
clinician experience and expertise
patient needs, conditions and preferences
4. Why study dental materials?: To enhance safety, promote awareness, maintain
materials properly, deliver correctly, and educate patients
EVOLUTION DEVELOPMENT PROPERTIES MANIPULATION CARE EVALUA-
TION
5. what does EBDM do for a clinician: helps make decisions about what is relevant
to incorporate into the practice.
"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."
6. Why do we need to know the study of dental materials?: To understand the
behavior of materials
To handle materials properly
To assess and treat the patient
To educate the patient.
7. first historical developments of dental materials: 2500 B.C.E.: evidence of
mummies that were lacking teeth due to abscesses and periodontal disease.
1.77 million years ago: evidence of toothpicks among oldest known human fossils.
600-300 B.C.E.: treatment remedies were based on potions and prayer, not restora-
tive dentistry.
8. what was the first cement to be introduced?: Zinc oxide cement was the first
cement to be introduced (a cement used for cementing tiles).
, DENTAL MATERIALS TEST 1
9. Synthetic were introduced. In 1955 what technique was introduced
that used today instead this?: resins - adhesive
1955: Acid -etch technique was introduced used today in composite resins.
10. what was introduced as a means of preventive dentistry?: Fluouridation was
introduced as a means of preventive dentistry .
11. WHY IS IT IMPORTANT FOR DENTAL HYGIENISTS TO HAVE A GOOD
UNDERSTANDING OF BIOMATERIALS?: To educate the clients
Allergys
Signs and symptoms
12. Dental foresees -: too much fluoride
White spots are from ingesting too much fluoride - freckling or white spots can start
to look brown mottled enamel
13. what year was the first "gold crown" introduced?: Mid 1800's: First gold
crown (gold foil). Class IV gold foil restoration
14. QUESTIONS TO ASK WHEN INCORPORATING
EBDM INTO A PRACTICE?: 1)How does your practice make decisions about
techniques, technology and products being used?
2) How do you analyze scientific research to ensure your product provides clinical
benefit to your client?
3) Do you try product samples before giving them to your clients?
4) How does your office stay informed about newest advances in dentistry?
5) How do you incorporate client's needs and choices into your decision making
process?
15. Developing an evidence-based approach to addressing client concerns
will: Increase the potential for successful client care outcomes by understanding
the cause and effect relationship between biomaterials and selected
Increase the success of the treatment rendered
16. restoration: repair or replace tooth structure due to disease or trauma or to
change the appearance of the teeth
17. direct restorations and indirect: placed immediately and directly to prepared
tooth and will harden. one time thing
indirection involves customized tooth replacements and requires fabrication outside
the mouth usually. 2nd appointment needed,
18. preventative or therapeutic: used to prevent disease or trauma or therapeutic
action on teeth or oral tissues.
ex) sealants, to help prevent caries, mouth guards, to help prevent injury ect.
, DENTAL MATERIALS TEST 1
19. auxiliary materials: materials used to fabricate and maintain restorations, di-
rectly or indirectly - impression materials, gypsum, dental waxes, and finishing and
polishing materials.
20. biocompatible: 3They must not impede or adversely affect living tissue.
Materials may be acceptable for use on hard tissue but not on soft tissue.
Some materials may be therapeutic in small amounts but may be irritating or toxic
with longer or larger doses.
Materials used in the mouth should exhibit no adverse biologic response.
A pontic - false tooth
Abutment - supporting teeth
Retainers are placed over abutment.
21. types of restorations: 1. permanent
2. temporary
3. intermediate bases or thermal/chemical insulators
4, adjunct materials
22. AGENCIES RESPONSIBLE FOR STANDARDS: - American Dental Associa-
tion (ADA)
- Food and Drug Administration (FDA)
- International Dental Federation
- International Standards Organization (ISO)
23. U.S. Food and Drug Administration (FDA) protects the public by ensuring
that products meet certain standards of safety and efficacy.
There are 3 Classifications of medical/dental devices grouped according to
the amount of control needed to ensure their safety and efficacy:: CLASS I
Lowest risk
Good manufacturing standards and record keeping practices
Examples: gloves, prophy paste, OTC products
CLASS II
Products required to meet performance standards set by FDA OR ADA
Examples: amalgam restoration (silver filling), composite restoration (tooth colored
restoration)
CLASS III
Most regulated devices which support or sustain human life
