Q: Which of the following terms is used to describe the part of the instrument used to carry out the purpose and function of the instrument?
- Shank
- Handle
- Shaft
- Working end
- Face
A: Working end

Q: The more restricted the access, the more angulated a shank must be and the sharper the bends of the angles. Because the mesial surfaces of molars are much less accessible than the distal surfaces, the shank angles of the 13 and 14 are designed with deeper bends.
- Both statements are true
- Both statements are false
- The first statement is true and the second statement is false
- The first statement is false and the second statement is true
A: The first statement is true and the second statement is false

Q: Which of the following instruments designs is least likely to provide good tactile sensitivity?
- Moderately flexible shank

- Flexible shank
- Elongated shank
- Hollow metal handle
A: Rigid shank

Q: The inner surface of the blade of a scaler or curet is known as which of the following?
- Lateral surface
- Face
- Back
- Tip
- Cutting edge
A: Face

Q: Which of the following instruments has one continuous cutting edge around the face because the two sides are united without interruption by the rounded toe?
- Curved scaler
- Sickle scaler
- Straight scaler
- Universal curet
- Area-specific curet
A: Universal curet

Q: There are many variations in the design of area-specific curets. Which of the following objectives would be helpful in the design of area-specific curets?
- To facilitate access to heavy supragingival calculus
- To conform to the curvatures of roots
- Increased length of the instrument handle
- Shortened terminal shank for deeper pockets
- V-shaped back to facilitate sharpening
A: To conform to the curvatures of roots

Q: When scaling with a curet, the ideal angulation formed between the instrument face and tooth surface should be:
- 15 degrees
- 35 degrees
- 50 degrees
- 70 degrees
- 90 degrees
A: 70 degrees

Q: Area-specific curets have many design features in common with universal curets. All of the following characteristics apply to both except one. Which one is the exception?
- Rounded toe and back
- Two cutting edges on each end
- Paired, mirror-image working ends
- Straight shank for anterior, complex for posterior
- Available with a rigid or flexible shank
A: Two cutting edges on each end

Q: Which of the following instruments would be the best choice to remove heavy calculus from the proximal areas of the mandibular anterior teeth?
- Universal curet
- Area-specific curet
- Sickle scaler
- Hoe
- Chisel
A: Chisel

Q: Which one of the following instruments would you use on the lower anterior region with a push stroke?
- Periodontal file
- Chisel
- Hoe
- Sickle
- Curet
A: Chisel

Q: You have just completed scaling teeth 28 to 31 on Mr. Jones and have asked an instructor to give you a grade. Your hand and fingers are very sore. The instructor notices calculus on all of the interproximal areas and sees you shaking your wrist. She asks that you demonstrate your grasp and stroke in the area for her. What has most likely caused your soreness and lack of effectiveness in the area?
- Patient compliance
- Working too quickly
- A rigid grasp
- The instructor is wrong, you did fine
- Poor lighting
A: A rigid grasp

Q: Mr. Jones is going to have a filling placed after you finish scaling. The dentist has asked that you put on the rubber dam for him. When you place the rubber dam on this patient, what type of an instrument grasp will you need to use with the rubber dam clamp holder?
- Modified pen grasp
- Pen grasp
- Palm grasp
- Neutral grasp
A: Palm grasp

Q: If you work with a bent wrist while scaling, what condition might you develop?
- Carotid sinus reflex
- Caseous abscess
- Carpal tunnel syndrome
- Thoracalgia
- Osteoarthritis
A: Carpal tunnel syndrome

Q: Which type of finger rest allows the index finger of your nondominant hand to rest on the tooth adjacent to the one you are scaling, while your thumb is placed on the instrument shank for more lateral pressure?
- Traditional fulcrum
- Substitute fulcrum
- Supplementary fulcrum
- Reinforced fulcrum
- Unacceptable fulcrum
A: Reinforced fulcrum

Q: When scaling, the instrument is adapted for maximum usefulness of the working end or 2 to 3 mm of the toe third of a curet on a “flat” surface. On a line angle or convex surface of a narrow root, less than 2 mm will be adaptable.
- Both statements are true
- Both statements are false
- The first statement is true and the second statement is false
- The first statement is false and the second statement is true
A: Both statements are true

Q: All of the following are objectives for using assessment strokes with a curet except one. Which one is the exception?
- Determine the surface texture of the root
- Confirm the position of the curet at the base of the pocket
- Rehearse an intended movement prior to activation
- Remove fine calculus subgingivally
- Determine the completion of your scaling in the area
A: Remove fine calculus subgingivally

Q: Restoring a sharp cutting edge is one of the two main objectives to instrument sharpening. What is the other objective?
- Maintain the internal angle of the cutting blade at about 90 degrees
- Remove metal equally from the face and lateral surface
- Preserve the original shape of the instrument
- Maintain the angle between the instrument face and stone at 90 degrees
A: Preserve the original shape of the instrument

Q: Which of the following best indicates that an instrument is dull?
- The instrument grabs the plastic testing stick
- Light does not reflect from the cutting edge
- Each portion of the cutting edge engages the plastic testing stick uniformly as the blade advances
- The cutting edge presents a rounded, shiny surface
A: The cutting edge presents a rounded, shiny surface

Q: When sharpening the lateral sides of a sickle using a stationary instrument technique, which of the following is true?
- The face of the instrument is positioned so that it is parallel to the floor
- A face-to-stone angle of about 70 degrees is established
- The stone is moved in an up-and-down motion ending in an up motion
- Place more pressure on the up stroke
A: The face of the instrument is positioned so that it is parallel to the floor
