Indications for surgery- Review Flashcards
Non-surgical periodontal therapy =
SRP
What are the goals of non-surgical perio therapy?
- removal of plaque and calculus
- microflora alteration
- endotoxin removal
- “smooth” the surface
- tissue shrinkage
Enotoxins are released via:
gram negative bacteria
List the disadvantages of non-surgical perio therapy:
- depths of pockets determine efficiency
- loss of CT by SRP in healthy sites
- thin vs. thick tissue
- instrumentaiton of furcations
Endpoint of periodontal therapy: (2)
- Eliminate inflammation, BOP, suppuration, and disease progression
- Result in a functional, comfortable, healthy dentition with stable probing and attachment levels
SRP efficiency vs. OFD efficiency
pockets 1-3 mm
SRP: 86%
OFD: 86%
SRP efficiency vs. OFD efficiency
pockets 4-6mm
SRP: 43%
OFD: 76%
SRP efficiency vs. OFD efficiency
pockets greater than 6mm
SRP: 32%
OFD: 50%
Give the parameters for PERIO MAINTENANCE post-SRP:
- 6 weeks post-op
- good oral hygiene
- plaque score of less than 30%
- few 4mm pockets
Give the parameters for COMPRISED PERIO MAINTENANCE post-SRP:
- 6 weeks post-op
- 90% plaque score
- few 6mm pockets
Give the parameters for PERIODONTAL SURGERY post-SRP
- 6 weeks post-op
- plaque score of less than 30%
- few 6mm pockets
Biofilm and calculus are most commonly found (trapped) at:
CEJ & Line Angles
Why might biofilm and calculus get trapped at the CEJ?
due to it being a transition zone with increased roughness- especially in cases where the CEJ is exposed due to recessed gingiva
There is a ___% chance of leaving residual calculus or biofilm in pockets that are ____
85%; greater than 5mm
Bone loss starts:
interproximally
Why does bone loss start interproximally?
- food trap
- less keratinized tissue
- harder area for patients to keep clean
T/F: Non-surgically treated areas have a GREATER percentage of defects that convert from non-diseased to diseased sites than surgically treated areas.
True
_____ areas have a greater percentages of defects that convert from non-diseased to diseased than _____ areas.
non-surgically treated areas; surgically treated
T/F: Single rooted teeth are better for BOTH non-surgical modalities than molars
true
This card is saying that when comparing single rooted teeth (incisors, canines, etc) to molars, it does not matter whether therapy is OFD or SRP, it will respond better due to it only having one root
When comparing single rooted teeth to molars, the better prognosis of single rooted teeth is due to:
easier access and no furcations
