Q

What are the two objectives of root planing

make sure the root surface is biologically acceptable to the soft tissue

21
Q

In which conditions should you expect less than ideal results

A

slight periodontitis - responds to scaling alone
fibrotic tissues
defective restorations
very deep pockets and/or furcations

22
Q

True or False

there more experiences operators produce a significantly greater number of calculus-free root surfaces

A

True

23
Q

How much time is required for comprehensive subgingival treatment of one single tooth when hand instruments are used

A

6-8 minutes

24
Q

Which four locations do we miss the most

A

CEJ
furcation areas
line angles
deeper parts of the pocket

25
Q

True or False

complete removal of calculus from periodontally diseased root is rare

A

True

26
Q

If curettes cannot reach the bottom of deep pockets, what may be required to gain access

A

periodontal surgery

27
Q

True or False

most literature shows that ultrasonics are far superior to hand instrumentation

A

False, is shows that both are equally effective

28
Q

True or False

Hand instrumentation create a smooth surface while vibrating instruments and sonic scalers can roughen the root surface

A

True

29
Q

True or False
roots that re intentionally grooved during surgery have as good a response to surgery as roots that have been planed to be smooth

A

True

30
Q

What is the method to determine the clinical end point of instrumentation

A

smooth roots

31
Q

root planing renders roots free of tis

A

endotoxin

32
Q

True or False

Hand instruments are more effective in removing endotoxin in vivo

A

True

33
Q

True or False

ultrasonics can remove endotoxin

A

True

34
Q

True or False

It is clinically sound to remove all cementum because endotoxin is tenaciously adherent

A

False, endotoxin is more loosely adherent then though, it is clinically sound to remove some but not all cementum

35
Q

What is the cementum thickness in the cervical and apical portions of the root

A

cervical: 20-50µm
apical: 150-250µm

36
Q

What is the average number of strokes at a low force

A

40

37
Q

True or False

There is NO advantage to multiple sessions of root planing

A

True

38
Q

This is the pocket depth below which there is attachment loss and above which there is attachment gain for a procedure

A

critical probing depth

39
Q

What is the critical probing depth for root planing

A

2.9mm

40
Q

True or False

shallow healthy sites should be instrumented

A

False, they should not

41
Q

This is currently accepted as adjunctive therapy to SRP

A

antimicrobial photodynamic therapy (APT) [low level diode laser]

42
Q

Antimicrobial photodynamic therapy may promote periodontal healing how

A

bacterial killing
inactivating bacterial virulence factors
inactivating host cytokines that impair healing

43
Q

This is the process of deriding the soft tissue wall of the periodontal pocket

A

gingival curettage

44
Q

What does gingival curettage involve

A

the removal of ulcerated epithelium and inflamed connective tissue (granulation tissue)

45
Q

True or False

Inadvertant curettage occurs during root planing

A

True

46
Q

Why are curettage and root planing not separated

A

When intentional curettage is performed, the root is always planed, therefore it is impossible to separate the procedures

47
Q

Which is gingival curettage difficult to effectively accomplish

A

in deep pockets

48
Q

When is gingival curettage not justified

A

in chronic periodontitis

49
Q

What three local antimicrobial therapies are currently accepted as adjunctive therapy to SRP

A

slow releasing agents;
bioabsorable minocycline loaded microcapsules (Arestin)
doxycycline hyclate in a biodegradable polymer (Atridox)
chlorhexidine gluconate (PerioChip)

50
Q

This is a low dose doxycycline prescription for 90 days (possible complications)

A

Periostat

51
Q

Why would you wait 4-6 weeks to evaluate treatment

A

normal flora returns

4 weeks for attachment
