Summary
The number of scaling strokes directly impacts endotoxin reduction on root surfaces. Complete calculus removal, achieved in about 9.3 strokes, correlates with endotoxin levels found on healthy teeth.
Area of Science:
- Periodontology
- Dental Calculus Removal
Background:
- Periodontal therapy involves scaling and root planing to remove accretions.
- The precise mechanical therapy needed for complete root surface debridement is not well-defined.
Purpose of the Study:
- To evaluate the relationship between standardized scaling strokes and endotoxin reduction on the root surface.
- To determine the number of strokes required for effective calculus removal and endotoxin reduction.
Main Methods:
- Extracted human teeth with attachment loss were used.
- Standardized force instrumentation with a force-measuring curet was applied to calculus-laden root surfaces.
- Endotoxin concentration in collected debris was measured after intervals of scaling strokes.
Main Results:
- Endotoxin levels were significantly higher during the initial 1-5 scaling strokes.
- Complete calculus removal was achieved after an average of 9.3 strokes.
- Minimal endotoxin levels (0.03-0.306 EU/ml) were observed post-calculus removal.
Conclusions:
- The completion of calculus removal aligns with endotoxin levels comparable to those on clinically healthy teeth.
- Standardized scaling effectively reduces endotoxin, suggesting a quantifiable endpoint for periodontal therapy.
