How often should periodontal instruments be sharpened?
Answer: Before use if dull, and whenever the cutting edge becomes rounded
Instruments should be sharpened before use if dull and whenever the cutting edge becomes rounded to maintain clinical effectiveness.
For maximum control during periodontal instrumentation, the fulcrum should be placed:
Answer: As close to the working area as possible
Establishing a fulcrum close to the working area provides maximum control and reduces the risk of soft tissue injury.
Which type of stroke is used during scaling to dislodge calculus deposits?
Answer: Activation or power stroke
The activation or power stroke applies lateral pressure against the calculus deposit to dislodge and remove it from the tooth surface.
What water temperature is recommended for ultrasonic scaling?
Answer: Warm water for patient comfort and effective cavitation
Warm water is recommended for ultrasonic scaling as it enhances patient comfort and supports effective cavitation at the instrument tip.
When adapting a curette to a convex root surface, which portion of the working end should contact the tooth?
Answer: The toe-third of the blade
The toe-third (terminal 1–2 mm) of the curette blade should be adapted to the tooth surface to maintain proper angulation and prevent tissue trauma.
Which observation confirms that a curette is properly sharpened?
Answer: No light reflects from the cutting edge
A properly sharpened curette shows no light reflection from the cutting edge, whereas a dull, rounded edge will reflect light.
