Q

has good resistance to microleakage and is therefore recommended when the crown preparation will not extend more than 1 mm beyond the foundation tooth junction

A

Dental Amalgam

20
Q

can be shaped to ideal restoration form and serves well as a long-term interim restoration

A

Dental Amalgam

21
Q

a suitable choice to block out a small lesion

A

Resin-Modified Glass Ionomer Cement

22
Q

the material sets rapidly, enabling crown preparation with minimal delay

A

Resin-Modified Glass Ionomer Cement

23
Q

→ exhibits many of the advantages of glass ionomers
→ does not require condensation and sets rapidly

A

Composite Resin

24
Q

formulations that release fluoride are available

A

Composite Resin

25
Q

a cemented cast foundation is retained by tapered pins

A

Pin-Retained Cast Metal Core

26
Q

the preparation requires careful location and placement of the pinholes but is otherwise straightforward

A

Pin-Retained Cast Metal Core

27
Q
  1. Isolate the tooth.
  2. Design the tooth preparation for the foundation restoration
    with the geometry of the intended crown in mind.
  3. Limit the extent of the outline form.
  4. Retain unsupported enamel if convenient.
  5. Finish the cavosurface margins.
  6. Remove any carious dentin carefully and thoroughly with a
    hand excavator or a large round bur in a low-speed
    handpiece.
  7. Create optimum resistance form.
  8. Ensure that the foundation restoration has adequate
    retention.
A

STEP-BY-STEP PROCEDURES in AMALGAM CORE

28
Q

→ base is necessary to prevent thermal irritation if the preparation extends close to the pulp
→ calcium hydroxide liners should be reserved for use in deep cavities

A

Bases & Varnishes

29
Q

a rigid, well-contoured matrix allows the amalgam to be properly condensed and facilitates carving

A

Matrix Placement

30
Q

follows conventional practice, with particular attention to condensing into wells and around pins

A

Condensation

31
Q

after allowing time for setting, the dentist trims the amalgam away from the occlusal edge of the matrix and removes the wedges and matrix retainer

A

Contouring & Finishing

32
Q
  1. Isolate the tooth.
  2. Prepare the tooth for a casting.
  3. Using a syringe, apply the glass ionomer onto the tooth.
  4. Finish the preparation as for other types of cores.
A

STEP-BY-STEP PROCEDURES in

GLASS IONOMER CORE

33
Q

True or false

composite resin is much stronger than glass ionomer foundations, a difference that is correlated with the higher diametral tensile strength of the composite

A

True

34
Q

→ examination
→ probing depth
→ attachment levels
→ extents of mobility
→ crown-to-root ratios
→ furcal involvements
→ tissue health
→ presence of calculus
→ patients plaque control measures

A

DEFINITIVE PERIODONTAL TREATMENT

35
Q

→ vitality testing of all teeth in the dental arch

→ tenderness to percussion
→ abnormal sensitivity
→ soft tissue swelling and discoloration
→ fistulous tracts
→ discolored teeth
→ radiograph
→ orthograde (conventional root canal treatment)
→ retrograde (endodontic surgery, apicoectomy)

A

ENDODONTIC TREATMENT
CLINICAL ASSESSMENT

36
Q

True or false

for a tooth or implant to be treated with a restoration extending into the gingival sulcus (subgingival margin), approximately 5 mm of keratinized gingiva, at least 3 mm of which is attached gingiva, is recommended

A

True

37
Q

True or false

if less keratinized gingiva is present, or in localized gingival recession, a grafting or other gingival augmentation procedure should be considered

A

True

38
Q

is indicated to increase the width of the band of keratinized gingiva through surgical grafting

A

MUCOSAL REPARATIVE SURGERY

39
Q

used for an area of recession or lack of attached gingiva on a single tooth when amounts of keratinized gingiva in adjacent teeth or edentulous spaces are adequate

A

Laterally Positioned Pedicle Graft

40
Q

→ used when a single tooth or multiple teeth exhibit gingival recession
→ if the width of the attached keratinized gingiva is inadequate, a free gingival graft may be placed to increase it before the coronal positioning

A

Coronally Positioned Pedicle Graft

41
Q

→ most common gingival augmentation

A

Connective Tissue Graft

42
Q

involves the use of subepithelial connective tissue
graft harvested from the palate in a spit thickness manner, which allows the wound to be closed after removal of the graft tissue

A

Connective Tissue Graft

43
Q

connective tissue grafts can be utilized to:

A

o cover exposed roots
o augment deficient ridges
o attempt to rebuild papilla

44
Q

indications:
o clinical crown is too short to provide adequate retention
without the restoration impinging on the normal soft tissue
attachment (biologic width)
o improve appearance of multiple short teeth
o increase crown-to-root ratio

A

CROWN LENGTHENING PROCEDURES

45
Q

True or false

CROWN LENGTHENING PROCEDURES
can be accomplished either:

o surgically
o combination of orthodontic and periodontal techniques

A

True

46
Q

gingivectomy or removal of gingiva by electrosurgery or incision using blade alone, although osseous recontouring is most often needed to prevent encroachment of the prosthesis on the biologic width

A

SURGICAL CROWN LENGTHENING

47
Q

a full thickness mucoperiosteal flap is reflected and the osseous resection creates a 3.5 to 4.0 mm space between the gingival crest and the margin of the existing restoration or carious lesion

A

SURGICAL CROWN LENGTHENING
