Sample item

What does an increased periodontal probing depth primarily indicate?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Apical displacement of the junctional epithelium or gingival enlargement

Probing depth is the distance from gingival margin to pocket base and can increase from true attachment loss or gingival enlargement. Clinical attachment level distinguishes these mechanisms.

Option by option

  • A. Enamel hypoplasia

    Enamel hypoplasia is a developmental enamel defect.

  • B. Apical displacement of the junctional epithelium or gingival enlargement (correct)

    Correct. Both pocket formation and enlargement can increase probing depth.

  • C. Pulp vitality

    Pulp vitality is assessed with sensibility tests.

  • D. Improved attachment in every case

    Increased depth does not itself prove improved attachment.
