23
Q

T/F - Subg irrigation resulted in a reduction of pathogens, but then a return to baseline at 1-8 weeks.

A

TRUE

24
Q

T/F - Subg irrigation should be used as an adjunct to SRP.

A

TRUE

25
Q

T/F - Currently insufficient data to indicate routine use to augment SRP.

A

TRUE

26
Q

Subg irrigation: CHX vs. Betadine

A

CHX
-No significant difference than with H2O
—Possible difference in pockets 4-6 mm, but not more than 6

Betadine
-Possible enhanced effect in depths >7mm

27
Q

What are some limitations to Subg irrigation with medicaments?

A

Short half life

Minimal dispersion

Blood contact inactivates CHX

GCF flows outward

28
Q

T/F - A single episode of in-office subg irrigation to enhance SRP does NOT improve clinical healing.

A

TRUE

29
Q

What should be used at home for irrigation?

A

CHX, Listerine, Fluoride

Daily delivery benefit*

30
Q

Is Arestin a replacement for irrigation therapy?

A

NO

31
Q

How are Arestin-type products effective?

A

Reach the base of the pocket

Must be high enough concentrations to destroy the bacteria

Drug must stick around

32
Q

What are advantages of Arestin-like products?

A

Sustained higher drug conc in GCF

Better pt compliance/acceptance

Drug resistance has not become a problem

Site specific

33
Q

What are the characteristics of minocycline?

A

Bioadhesive

Bioresorbable

Safe

34
Q

What is minocycline?

A

Broad spec

Semi-synthetic derivative of tetracycline

  • Effective against the RED COMPLEX*
  • MIC is high
  • pH is changed
35
Q

T/F - Minocycline achieves high local conc w/ minimal systemic levels.

A

TRUE

36
Q

What does Arestin do?

A

Decreases pocket depths

Doesn’t do much to attachment level

37
Q

2 sites where Arestin and SRP delivered enhanced efficiency to difficult to treat sites and pts?

A

Molars

Furcation sites

38
Q

3 pt groups where Arestin and SRP enhance efficacy?

A

Smokers

Elderly

Pts with current CV disease or CV disease history

39
Q

Can Arestin be used to treat periodontitis?

A

NO

-B/c it does nothing to attachment loss, which is a hallmark of periodontitis

—It DOES decrease pocket depth by decreasing the swelling in the pocket by killing the bugs

40
Q

T/F - Arestin + SRP are significantly more fertile in reducing pocket depth than SRP alone.

A

TRUE

41
Q

T/F - Repeated therapy w/ minocycline prolongs efficacy and minocycline is easy to use, well-tolerated, and safe.

A

TRUE

42
Q

What are pt instructions after Arestin application?

A

No brushing for 12 hours

Avoid eating hard, crunchy, or sticky foods for 1 week

Postpone use in interproximal cleaning devises for 10 days (including floss)

*Maintains therapeutic conc for up to 14 days

43
Q

What is Atridox?

A

Doxycycline gel

Must be removed after 7-10 days via flossing or toothbrushing

44
Q

What is Atridox used for?

A

Tx of chronic adult periodontitis for a gain in clinical attachment, reduction in probing depth, and reduction in BOP

*It physically pushed the tissues away and required them to re-attach

45
Q

What are the contraindications for Atridox?

A

Pts hypersensitive to doxycycline or any other drug in the tetracycline class

46
Q

T/F - SRP results in increased attachment.

TRUE

48
Q

T/F - Approved as a mono therapy and should be used as an adjunct to mechanical tx.

A

TRUE

49
Q

What is the chemical in PerioChip?

A

Chlorhexidine

50
Q

How deep should pockets be for PerioChip tx?

A

5 mm

Pt should not brush or floss for 7 days

51
Q

T/F - For a pt that received a locally delivered system, results should be seen 10 days to 14 days. If improvement, resume recalls. If no improvement, re-apply or refer.

A

TRUE

52
Q

T/F - In the 70s, it was thought:

Treat PD as bacterial infection

Only few specific organisms that needed to be targeted

Thought to be exogenous and could eliminate from body indefinitely

Noteworthy successes

A

TRUE

53
