In periodontitis, which of the following provides effective MECHANICAL protection to the periodontal tissues?
Show answer and explanation
Correct answer: C. Epithelial shedding (desquamation)
✓ C) Epithelial shedding is correct.
The oral epithelium provides mechanical protection through its continuous desquamation (shedding of surface cells), which physically removes attached bacteria and prevents colonization. This is a key innate defense mechanism in the periodontium. Proteases are released by bacteria and neutrophils — they contribute to tissue destruction. Antigen-presenting cells are immunological (adaptive) rather than mechanical defense mechanisms.
