Dentistry · Caries, pulp and periodontal disease: occlusal trauma and periodontitis
Sample itemA tooth with excessive occlusal force but healthy, plaque-free gingiva is examined. Which finding is expected?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Increased mobility with a widened periodontal ligament space but no pocket or attachment loss
Trauma from occlusion damages the periodontal ligament and alveolar bone, giving mobility, a widened ligament space and sometimes vertical bone changes. By itself it does not start gingivitis or cause pocket formation and loss of attachment. It can, however, worsen existing plaque-induced periodontitis.
Option by option
A. A deep periodontal pocket with pus
Pus and deep pockets indicate infection, not force alone.
B. Furcation involvement with attachment loss
Furcation involvement with attachment loss indicates periodontitis.
C. Increased mobility with a widened periodontal ligament space but no pocket or attachment loss (correct)
Correct. Occlusal force alone alters the ligament and bone but does not create pockets.
D. Gingival bleeding with calculus
Bleeding and calculus reflect plaque-related inflammation.
