Exam 17: Instrumentation for Client Assessment and Care

The clinician is having difficulty accessing the lingual aspect of a maxillary posterior sextant. For right-handed clinicians, this is the maxillary right posterior sextant, lingual aspect. For left-handed clinicians, this is the maxillary left posterior sextant, lingual aspect. The client and clinician chairs are correctly positioned for the treatment area. Which of the following might allow better access?

Blowing a stream of compressed air on mandibular anteriors reveals a sheet of light calculus covering the lingual aspect of tooth #22 to #27. Which of the following techniques would be BEST for calculus removal?

While exploring the mandibular anterior sextant with the ODU 11/12 periodontal explorer, it is difficult to insert the explorer without unduly distending the tissue. Which of the following techniques might cause less tissue distension?

A right-handed clinician is working on the buccal aspect of tooth #2. (For a left-handed clinician, this area would be equivalent to the buccal aspect of tooth #15.) The clinician is using a Gracey 13/14 curet and retracting the client's cheek with a mouth mirror. The clinician's neck is bent excessively as she works. What correction should the clinician make for more ergonomic positioning?

The best way to remove the black line stain on the lingual aspects of both arches is to:

Access to subgingival calculus deposits on the proximal surfaces of the mandibular anterior teeth is difficult because of papillary enlargement of the gingival tissue. Which of the following statements provides the BEST advice for thorough subgingival calculus removal?

During periodontal instrumentation for calculus removal, the clinician's hand becomes fatigued. Self-assessment indicates he has been using finger motion with a hand instrument for calculus removal. Digital activation is acceptable for all of the following situations EXCEPT one. Which one is this EXCEPTION?

The client has chronic periodontal disease with fibrotic tissue. Tenacious moderate black subgingival calculus is present on most tooth surfaces. Which of the instrument(s) listed below would be the BEST choice to initiate removal of the moderate calculus deposits?

While removing calculus from the maxillary anterior tooth surfaces toward the clinician, good adaptation of the toe-third of the working end is facilitated by:

To determine if the client has calculus deposits on the proximal surfaces of the posterior teeth, the instrument of choice would be_______________ and the instrumentation stroke used would be____________________.

The suggested place to begin probing by quadrants is the distal line angle of the posterior-most tooth in the quadrant. The working end of the probe is removed from the sulcus or the pocket after each bobbing stroke.

A periodontal instrument has the following design features: The face is perpendicular to the lower shank, the cutting edges are level with each other, and the working end has a rounded toe. Which of the following instruments also exhibits these design criteria?

Tooth #3 has a class II furcation involvement on the facial aspect. Of the instruments listed below, which would be the BEST choice for smoothing the roof of the furcation area?

A full mouth radiographic survey indicates the presence of subgingival calculus in the mandibular right posterior sextant, but the clinician is unable to detect it with an ODU 11/12 explorer. All of the following may contribute to an inability to detect calculus EXCEPT one. Which one is the EXCEPTION?

The client has porcelain veneers on the facial aspect of her maxillary anterior teeth. Which of the following polishing techniques for the removal of extrinsic stain would be considered the standard of care for a client with porcelain veneers and dental implants?

If the clinician decides to use ultrasonic equipment instead of hand instruments, she needs to keep contraindications for ultrasonic use in mind. Which of the following is NOT a contraindication for use of ultrasonic equipment?

Because of her pregnancy, it is uncomfortable for the client to lie in the supine position with the back of the chair raised slightly. To ensure client comfort and facilitate the clinician's access to the maxillary arch, which of the following strategies would be helpful?

While removing calculus deposits from mandibular anterior teeth, the presence of heavy bleeding makes the tooth surfaces slippery. Which of the following fulcrums would give the clinician the GREATEST stability and less chance for an occupational exposure while removing calculus deposits from the mandibular anterior sextant?

When performing a coronal polish, all of the following areas should be avoided EXCEPT one. Which one is the EXCEPTION?

Which one of the instruments listed below is the BEST choice for efficient removal of light subgingival calculus from the proximal surfaces of the client's posterior teeth?
