PSR does not take bleeding points into consideration, and a comprehensive periodontal charting does D. PSR does not take recession into consideration, and a comprehensive periodontal charting does

B. PSR records one code for each sextant, and comprehensive periodontal charting records six readings for each tooth

When assessing your patient's maxillary right first molar for furcation involvement, the probe penetrated into the furcation but did not go through to the lingual.

The probe was not used properly

B. The lingual root stopped the probe

B. The presence of exudate

During a periodontal assessment, the hygienist records the following findings on the periodontal chart for the facial aspect of a tooth: - Gingival margin level = 0 mm - Probing depth measurement = 7 mm What is the clinical attachment loss for the facial surface of the tooth?

C. Class 3

During a periodontal assessment on a patient, the hygienist uses a probe to measure the distance from the CEJ to the base of a pocket. What clinical measurement is the hygienist obtaining? A. A probing depth B. Width of the attached gingiva C. Clinical attachment level D. Mucogingival junction level

C. Clinical attachment level

Mrs. J is a new patient in your dental practice, the hygienist begins with a fact-gathering process designed to provide the hygienist with a comprehensive picture of Mrs. J's periodontal health status. The procedure the hygienist is performing is termed a: A. Periodontal screening examination B. Thorough intraoral inspection C. Comprehensive periodontal assessment D. Mucogingival examination

C. Comprehensive periodontal assessment

Miss A is very concerned about her maxillary right canine. The hygienist places his gloved index finger against the facial surface of the crown and asks Miss A to tap her teeth together. The hygienist is assessing the tooth for: A. Vertical tooth mobility B. Horizontal tooth mobility C. Fremitus D. Furcation involvement

C. Fremitus

The dental hygienist is assessing a mandibular molar tooth with a Nabers furcation probe. The furcation probe passes completely through the furcation between the mesial and distal roots; however, the entrance to the furca is not visible clinically. The level of furcation involvement should be recorded as a class of: A. I B. II C. III D. IV

C. III

A dental hygienist is reviewing the periodontal chart for a patient that is scheduled for tomorrow. The periodontal chart indicates that all the probing depths are between 1-3 mm. The periodontal chart does not indicate the position of the gingival margin or any clinical attachment readings. Can the dental hygienist assume that this patient has a healthy periodontium? A. Yes, probing depths between 1-3 mm are considered normal B. If the patient is scheduled with the hygienist, the patient probably has gingivitis C. No, because the chart provides no way to tell if the patient has attachment loss D. Yes, because there is only one hour scheduled for this patient

C. No, because the chart provides no way to tell if the patient has attachment loss
