Exam 17: Instrumentation for Client Assessment and Care

An intraoral fulcrum is accomplished by establishing a finger rest near the tooth to be instrumented. Establishing a finger rest as close as possible to the working end of the instrument is preferable so the fingers in the grasp will remain touching.

A clinician is having difficulty keeping the lower shank parallel to the long axis of tooth #3. The clinician is using a Gracey 13/14 curet with a miniature working end and an extended lower shank. Which of the following would MOST LIKELY improve access in this distolingual surface?

The clinician is using hand instruments to remove moderate calculus deposits. After 30 minutes, the clinician's hand muscles become noticeably fatigued. Potentially, all of the following can cause hand fatigue EXCEPT one. Which one is the EXCEPTION?

The client started gagging on the ultrasonic's water spray, so the clinician decides to use a hand instrument to remove a tenacious, moderate calculus deposit on the facial surface of tooth #31. The calculus deposit is located supragingivally on the crown of the tooth. Which of the following instruments would you choose?

A large piece of burnished calculus is present on the distal aspect of tooth #2. Which instrument would be MOST effective in preparing the burnished deposit for eventual removal with another periodontal instrument?

One of the client's chief complaints is dry mouth. All of the following are useful suggestions for the client to minimize the effects of xerostomia EXCEPT one. Which one is the EXCEPTION?

To remove light subgingival calculus from the furcation area of a mandibular molar, which of the following instruments would be MOST efficient?

The posterior sextants exhibit moderate supragingival and subgingival calculus deposits. Clinical attachment loss is present with periodontal pockets greater than 4 mm in depth. The clinician plans to complete calculus removal on the maxillary right posterior sextant. He plans to use a series of ultrasonic tips followed by hand instruments. Which sequence of ultrasonic tips would be MOST effective for calculus removal in this sextant?

Tooth #8 is restored with a porcelain-fused-to-metal crown. Which of the following instruments is contraindicated for use around tooth #8?

Which of the following instruments would be the MOST effective in removing a small subgingival calculus deposit on the lingual aspect of tooth #24?

The clinician determines that many of the client's multiple-rooted teeth have loss of clinical attachment. This information should prompt the clinician to use the following instrument to assess for possible furcation involvement.

Teeth #19 and #20 have been replaced with dental implants. Which of the following instruments would be the BEST choice to remove light calculus from the prosthetic crowns of these dental implants?

What type of stroke pressure usually is required to remove a calculus deposit from the prosthetic crown of a dental implant?

Before beginning calculus removal, the clinician uses an explorer to determine the type, amount, and location of calculus deposits. Which of the following explorers is NOT recommended for calculus detection?

The client's mandibular anterior teeth are in linguoversion and are crowded. The clinician is having difficulty accessing the lingual surfaces of these mandibular anterior teeth. Which of the following patient positioning suggestions is BEST to ensure an ergonomic instrumentation technique?

To minimize client discomfort during root surface debridement in periodontal pockets, the clinician should use caution when inserting a universal curet beneath the gingival margin. The face-to-tooth surface angulation during insertion of the working end beneath the gingival margin is between:

Which of the following ultrasonic tips would be MOST efficient for removing the heavy ledge of supragingival calculus on the client's mandibular anterior sextant, lingual aspect?

The straight calibrated periodontal probe can be used for all of the following assessment procedures EXCEPT one. Which one is the EXCEPTION?

Which of the following instruments would be the BEST choice for removing the light subgingival calculus deposits on the proximal surfaces of the posterior teeth?

The client has several areas of existing root caries and xerostomia. This combination places him at extreme risk for caries. All of the following are recommended management strategies for caries prevention EXCEPT one. Which one is the EXCEPTION?
