exam 2 (L1) - rationale for perio surgery Flashcards
What happens if we don’t treat periodontitis?
tooth loss
Surgery advantages:
- direct root vision
- easier tissue manipulation
surgery disadvantages:
- morbidity
- esthetics
- cost
Closed SRP leads to more calculus on _______ _____, while open SRP leaves calculus on ______ _______ (+CEJ).
- smooth surface
- surface concavity
residual calculus after SRP common in what areas?
- deeper pockets
- posterior teeth
- proximal surfaces
- closed procedures
T/F : Flaps reduce calculus as opposed to no flaps.
T
Why do the gingiva heal slower in the presence of calculus?
inflammation from adherent plaque
What are 2 risk factors for perio onset mentioned in this lecture?
- amount subgingival calculus
- subgingival A.a.
When does SRP become ineffective?
when sites are 7 mm or deeper
Which is more effective at periodontal reduction, SRP or surgery?
surgery
T/F : Perio tissue breakdown occurs more rapidly in the shallower sites than the deeper sites.
F
In studies comparing surgical to non-surgical tx, how did the non-surgical pt w/ severe perio fare VS those who had surgery?
- deeper probe depths
- furcations
- increased mobility
How were probing depths in surgically tx teeth affected?
greatly reduced PD
- Surgical tx provides (better/worse) short-term pocket reduction than non-surgical tx.
- Surgical tx provides (better/worse) long-term pocket reduction than non-surgical tx.
- Surgical tx may be responsible for (more/less) pt needing additional perio therapy.
- better
- better
- less
Surgical debridement VS non-surgical:
- surgical results in (more/less) pocket reduction.
- surg results in (more/less/no) clinical attachment GAIN
- more
- more
