Root Planing Flashcards
What characteristics are common to pseudo and true pockets?
- Bacterial biofilm
- Calculus
- Chronically inflamed pocket wall
- Destructive host response
What characteristics are unique to a true pocket?
- Altered root cementum
- Apical migration of attachment
- Bone loss
T/F: Calculus is a mechanical and chemical irritant.
False
It is a plaque retentive feature
T/F: Diseased cementum is a barrier to repair, and perpetuates tissue destruction.
True
What are some methods to alter the subgingival microenvironment?
- Caries control
- Replace restorations
- Subgingival instrumentation
- Local chemotherapeutics
- Surgical corrections
- Extractions
- Quit smoking
- Ortho
What is the rationale for subgingival instrumentation?
Remove plaque, plaque retentive factors, remove diseased surfaces
Subgingival instrumentation of the soft-tissue is called _______. Subgingival instrumentation hard tissue is called _______.
curettage; root planing
What is the difference between root planing and subgingival scaling?
RP: Designed to remove cementum or surface dentin that is rough or diseased
SS: Designed to remove plaque, calculus, and stains
_________ uses shaving strokes and is performed in periodontitis only.
Root planing
What are the steps of periodontal healing?
- Repair
- Reattachment
- New attachment
- Regeneration
What are three major keys to effective root planing?
- Sharp instruments
- Access to cemental surface
- Correct instrument angulation
What are the ideal conditions for root planing?
- Moderate inflammation
- Moderate pocket depth
- Slight-moderate periodontitis
- Obvious deposits
T/F: Slight periodontitis is positively effected via root planing.
False
Actually causes attachment loss
T/F: Very deep pockets and furcations are good for root planing.
False
How long does the literature say is necessary to spend on each tooth for the best results?
6-8 minutes/tooth
What are the most often missed areas during root planing?
CEJ, furcations, line angles, deep pockets
When is periodontal surgery a good alternative to root planing?
Very deep pockets where curettes cannot reach the bottom
T/F: Ultrasonics are more effective in calculus removal.
False
Both are equal but ultrasonics may be easier on the operator
T/F: Hand instruments may be better in smoothing a rough root.
True
How do you determine the end point of instrumentation?
Smooth roots
What is the effect of root planing on LPS?
Renders the roots free of LPS
T/F: Cementum is much thicker in the cervical portion of the root.
False
Thinner at cervical
Thicker at apical
T/F: It is advantageous to have multiple episodes of SRP if the patient does not respond.
False
What is the critical probing depth for root planing?
The depth at which planing will be helpful and not cause damage - 2.9 mm
T/F: Treating perio pockets with a laser is acceptable as replacing SRP.
False
Adjunctive therapy to SRP
T/F: Curretage and root planing are completely separate procedures.
Although they are different it is impossible to do one without the other
T/F: Gingival currettage is justified in chronic periodontitis.
False
Difficult to accomplish in deep pockets
