20
Q

Prophys should ONLY be done in:

A

periodontal health

21
Q

In patients with thin phenotype gingival, these patients are more susceptible to:

A

recession

22
Q

What does bleeding on probing tell us?

A

inflammation is present

23
Q

What is the instrument of choice in furcation areas?

A

cavitron

24
Q

Regeneration that involves bone from self:

A

autografts

25
Q

Regeneration that involves bone of the same species:

A

allograft

26
Q

Regeneration that involves bone from different species (sheep, cow, etc):

A

xenografts

27
Q

Synthetic product made in lab that stimulates replication/growth of the bone:

A

alloplast

28
Q

Because cells move at a very different pace, excluding the epithelium or connective tissue and allowing the bone cells to move in at a slower place, guiding the cells we want to grow into that area:

A

guided tissue regeneration

29
Q

Guided tissue regeneration membrane will provide:

A

epithelial exclusion

30
Q

Gram negative anaerobic microflora produce ___ causing mediators to come in and we get ___

A

endotoxins; inflammation

31
Q

What type of bacteria in the microflora cause inflammation leading to periodontitis?

A

gram negative anaerobic

32
Q

T/F: Periodontal disease typically causes pain

A

false

33
Q

T/F: Hand instruments are best option when scaling in furcation areas

A

False- cavitron is better fit due to hand instruments being too big

34
Q

How do you prove regeneration?

A

measure from CEJ to alveolar crest is a good start to because it tells us something has filled that gap, but the only way to measure for TRUE regeneration is to take out the tooth (which you won’t do)

35
Q

To prove regeneration has occurred by extracting a tooth (you really wouldn’t do this), you would look under the microscope for:

A
  1. osteoblasts
  2. cementoblasts
  3. periodontal ligament cells
36
Q
  • Osseous contouring with placement of the flap margin at the alveolar crest
  • creation of shallow sulci
  • ease of maintenance by therapist and patient
A

pocket elimination via surgical therapy

37
Q

What is seen in AGGRESSIVE periodontitis?

A

bacterial penetration

38
Q

Aggressive periodontitis was formerly known as:

A

LJP/GJP

39
Q

What is the causative bacterial pathogen seen in aggressive periodontitis?

A

A.a

40
Q
  • regain periodontium
  • remove frena
  • increase root coverage
  • increase keratinized tissue
  • restore gingival topography
  • pre-prosthetics & pre-orthodontics
A

Mucogingival surgery/ Periodontal plastic surgery

41
Q

Re-treatment of case is an indication for periodontal surgery and is performed when:

A
  1. non-surgical therapy has failed
  2. surgical therapy has failed
  3. new techniques or materials are available
42
Q
  • crown lengthening
  • ridge augmentation
  • palatal recontouring
  • gingivectomy/gingivoplasty
  • ridge or tuberosity reduction

these are are all forms of:

A

pre-prosthetic surgery

43
Q

What drugs may lead to drug-induced gingival overgrowth?

A
  1. dilantin
  2. cyclosporin
  3. calcium channel blockers (nifedipine)
44
Q

T/F: Non-surgically treated areas have a lesser percentage of defects that convert from non-diseased to diseased sites than surgically treated sites

A

false- greater percentage

45
Q

____ areas have a greater percentages of defects that convert from non-diseased to diseased sites than ____ sites

A

non-surgically treated; surgically treated

46
Q

All studies show that results in single rooted teeth are ___ for both non-surgical AND surgical modalities than molars

A

better

47
Q

____ are NOT indicated until periodontal disease has been controlled and all other dental needs are addressed in a comprehensive treatment plan

A

Implants

48
Q

Implants are NOT indicated until:

A

periodontal disease has been controlled and all other dental needs are addressed
