d. both statements are false

c. both statements are true

9

The prosthodontic phase of implant treatment involves the placement of several "parts" or attachments. a patient who has completed the surgeries and restorative care would receive in, in order:

c. cylinder, implant, crown, abutment
d. implant, abutment, cylinder, crown

d. implant, abutment, cylinder, crown

 

  1. first surgery an implant is placed
  2. in the next surgery a healing cap is placed, which is exposed to the oral cavity
  3. later the healing cap is removed and an abutment is placed the implant.
  4. It acts as an abutment of a bridge and supports the prosthesis.
  5. A cylinder is then placed on the abutment, and then a crown is placed on the cylinder.

10

All of the following should be included in the post care maintenance of a patient with an implant except one. Which one is the exception?

a. necessary chairside, home care instructions
b. recommended auxiliary aids
c. selecting the restorative material for an adjacent restoration

the scope of practice of dental hygiene does not include selecting restorative material for tooth restoration.

11

a. accessing the canal
b. filling and sealing the canal
c. placing the final restoration
d. removing the contents of the pulp

b. filling and sealing the canal

12

which type of composite gives the clinician an advantage when removing orthodontic resins during bonding?

a. microfilled
b. macrofilled
c. hybird
d. none of the above

b. macrofilled

13

The endodontic surgical procedure that removes 1-3 mm of the root apex is called a(n):

a. endodontic retreatment
b. retrofill
c. root resection
d. apicoectomy

d. apicoectomy

14

What is used to disinfect the canal system by killing bacteria and dissolving plural tissue?

a. endodontic sealers
b. paper points
c. irrigants
d. gutta percha

c. irrigants

15

which orthodontic device prevents "relapse" of the teeth?

a. archwire
b. ligature
c. bracket
d. retainer

d. retainer

16

the debonding procedure is done after orthodontic treatment is completed. The dental material removed from tooth surface is:

a. composite resin
b. cold cure resin
c. dental cement
d. ligature material

a. composite resin

Brackets are secured to the tooth surface by acid etching and composite resin

17

the most commonly used technique to fill a root canal with gutta-percha is termed:

a. direct compression
b. lateral compression
c. direct condensation
d. lateral condensation

d. lateral condensation

Lateral condensation is used to fill the root canal with gutta-percha.

Condensation is a term used in dentistry to describe the method of compressing and filling a small area in a tooth such as a preparation or root canal.

18

a pulpotomy usually serves as a ___________ procedure on permanent molars.

a. temporary
b. permanent
c. either temporary or permanent
d. neither temporary or permanent

a. temporary

for permanent molars a pulpotomy is a temporary procedure and is followed by a root canal therapy.

For primary molars, it is a permanent procedure and is restored with a stainless steel crown. This will maintain space and function until the permanent molar takes it's place.
