Week 3 Advanced Techniques Flashcards
Why must instruments be sharpened for efficient scaling, root planing, or debridement?
Sharpened instruments minimize tissue trauma, burnished calculus, clinician fatigue, and patient discomfort. They also improve tactile sensitivity, precision, and calculus removal.
How can you identify a sharp cutting edge on an instrument?
A sharp cutting edge is a fine line with no light reflection and “bites” the test stick, whereas a dull edge is flat or beveled and slides over the stick.
What are the benefits of using sharpened instruments for periodontal debridement/root debridement/root planing?
Sharpened instruments increase efficiency, improve tactile sensitivity, and ensure complete calculus removal, which are crucial for effective debridement and root planing.
What characteristics of root morphology make instrumentation challenging?
Root concavities and irregularities, such as grooves or furcations, make instrumentation difficult. Clinicians need a mental picture of root anatomy and tactile sensitivity to adapt instruments effectively
How do advanced instrumentation skills relate to root morphology, instrument selection, and technique?
using area-specific curettes, extended shank instruments, and supplemental fulcrums to access deep or multi-rooted areas.
Which instruments are appropriate for root instrumentation based on their design?
Area-specific Graceys, extended shank curettes, and power instruments with appropriate tips
How do power instrumentation and hand instrumentation differ in therapeutic and maintenance procedures?
Power instruments, such as ultrasonic scalers, are effective for rapid calculus removal and biofilm debridement. Hand instruments offer more control and precision for root planing and complex root morphology.
How many cuttting edges does a universal, area specific curet and scaler have?
Universal: Two cutting edges
Area-specific: One Cutting edge
Scaler: Two
