Questions and Answers

1.

True or false?Having instruments set-up in sequential order of use and placed out before a procedure saves time.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Having instruments set up in sequential order of use and placed out before a procedure saves time because it eliminates the need for healthcare professionals to search for and gather the necessary instruments during the procedure. This ensures that all required instruments are readily available and easily accessible, allowing for a smoother and more efficient workflow. Additionally, having instruments set up in order of use reduces the risk of errors or omissions during the procedure, further saving time by avoiding the need for corrections or additional steps.

Correct Answer
A. Cryer elevator

Explanation
A composite instrument tray is typically used in dental procedures involving composite fillings. The instruments commonly found in this tray include applicator brushes for applying the composite material, clear matrix strips for creating a temporary wall around the tooth, and plastic flat plastic for shaping and contouring the composite. However, a Cryer elevator is not commonly found in a composite instrument tray. A Cryer elevator is a dental instrument used for luxating and extracting teeth, which is not directly related to composite fillings.

- C.
  
  K-files
- D.
  
  Endodontic long-shank spoon
Correct Answer
A. Barbed broaches

Explanation
Barbed broaches are not commonly found in an endodontic tray. Endodontic trays typically contain instruments such as endodontic locking forceps, K-files, and endodontic long-shank spoons, which are used for various procedures in endodontics. However, barbed broaches are not commonly used in endodontic procedures and are therefore not typically included in an endodontic tray.

Correct Answer
A. Spoon excavator

Explanation
A spoon excavator is not commonly found in a hygiene instrument tray. A spoon excavator is a dental instrument used for removing soft carious dentin during a restorative procedure. It is typically used by dentists rather than dental hygienists who focus more on preventive care and scaling. The other instruments listed - periodontal probe, sickle scaler, and Gracey currette - are commonly found in a hygiene instrument tray and are used by dental hygienists for scaling and root planing procedures.

- B.
  
  Slow speed handpiece
- C.
  
  Prophy cup and brush
- D.
  
  Cotton forceps
Correct Answer
A. Millers forcepts

Explanation
The correct answer is Millers forcepts. Millers forcepts are not commonly found in a prophylaxis polishing instrument tray. Millers forcepts are typically used in oral surgery procedures for grasping and manipulating tissues, whereas a prophylaxis polishing tray contains instruments specifically for teeth cleaning and polishing, such as a slow speed handpiece, prophy cup and brush, and cotton forceps.

All of the following instruments are commonly found in a sealant instrument tray, except?
- A.
  
  Dental clamp
- B.
  
  Millers forceps
- C.
  
  Explorer/probe
- D.
  
  Cotton forceps
Correct Answer
A. Dental clamp

Explanation
A sealant instrument tray is typically used in dental procedures to apply sealants to teeth. The instruments commonly found in this tray include millers forceps, explorer/probe, and cotton forceps. These instruments are used for various purposes such as gripping, exploring, and handling materials. However, a dental clamp is not commonly found in a sealant instrument tray. Dental clamps are used to isolate and stabilize the tooth during certain procedures, but they are not specifically used for sealant application. Therefore, the dental clamp is the correct answer as it is the instrument that is not commonly found in a sealant instrument tray.

- C.
  
  Explorer/probe
- D.
  
  Cotton forceps
Correct Answer
A. Millers forceps

Explanation
Millers forceps are not commonly found in an orthodontic cementing and bonding brackets instrument tray. Millers forceps are typically used in oral surgery procedures to extract teeth, while the other instruments listed are specifically designed for orthodontic purposes. Bracket placement pliers are used to accurately position brackets on teeth, explorer/probe is used to examine tooth surfaces for decay or irregularities, and cotton forceps are used to handle cotton rolls or other materials during orthodontic procedures.

  Half hollenback
- B.
  
  Periosteal elevator
- C.
  
  Mandibular molar extraction forceps
- D.
  
  Needle holder
Correct Answer
A. Half hollenback

Explanation
A surgical extraction of an impacted mandibular molar requires specific instruments to aid in the procedure. The periosteal elevator is commonly used to separate the gum tissue from the bone, while the mandibular molar extraction forceps are essential for gripping and extracting the tooth. The needle holder is used to hold and manipulate needles during suturing. However, the half hollenback instrument is not typically used in this procedure. It is a dental instrument commonly used in restorative dentistry for contouring and shaping dental materials.
