Which Gracey curette is specifically designed for scaling the mesial surfaces of posterior teeth?
Answer: Gracey 11/12
Gracey 11/12 curettes are area-specific instruments designed to adapt to mesial surfaces of posterior teeth.
What is the correct blade angulation of a curette to the tooth surface during active scaling?
Answer: 45–90 degrees
A blade angulation of 45–90 degrees to the tooth surface is required for effective calculus removal with a curette.
Which ultrasonic scaler insert is best suited for removing heavy supragingival calculus?
Answer: Beaver-tail insert
Beaver-tail inserts are designed for heavy supragingival calculus removal due to their robust, broad design.
The modified pen grasp is preferred for periodontal instrumentation primarily because it:
Answer: Allows tactile sensitivity and precise control
The modified pen grasp provides optimal tactile sensitivity and precise control during subgingival instrumentation.
What is the primary purpose of root planing compared to scaling?
Answer: Smooth the cementum and remove embedded endotoxins
Root planing smooths cementum and removes embedded endotoxins to create a biologically compatible root surface for tissue reattachment.
Which stroke direction is most effective for subgingival calculus detection with an explorer?
Answer: Overlapping vertical and oblique strokes
Overlapping vertical and oblique strokes with an explorer ensure complete detection of subgingival calculus deposits across all root surfaces.
