Daphane makes one measurement near the center of the lingual site on a mandibular first molar. That measurement is 6mm. What does this measurement indicate?

A. A decision by the patient to reject treatment should happen before informed consent. B. Informed refusal forms should be a part of patient documentation.

first statement is false; second is true

A. It is preferable that patients consent to treatment plans verbally. B. A patient must have capacity to consent.

first statement is false; second is true

first statement is false; second is true

A. The periodontal probe should be removed from the sulcus after each measurement. B. The pressure of the probe tip against the junctional epithelium should be between 10 and 20 g.

first statement is false; second is true

A. A calibrated periodontal probe is marked in millimeter intervals. B. Each millimeter increment (from 1 to 12 mm) is indicated on the working-end of all calibrated probes.

first statement is true; second is false

A. Probing depths may be overestimated due to swollen gingival tissue. B. Probing depths will be most accurate before you remove heavy subgingival calculus.

first statement is true; second is false

A. The millimeter markings on periodontal probes may be indicated by indentations in the metal, colored indentations, or colored bands. B. The millimeter marks on all color-coded probes are placed at 3, 6, 9, and 12 mm.

Franklin is probing a maxillary first premolar where the gingival margin is at the CEJ. He records the following measurements on the periodontal chart: facial aspect = 4, 4, 4 and lingual aspect = 4, 4, 4. Do the measurements indicate that the premolar has a normal sulcus or a periodontal pocket?

these measurements indicate a periodontal pocket

this tooth has a periodontal pocket and some of the alveolar bone surrounding the root has been lost
