Periodontics · single question

All describe pathogenicity of dental plaque EXCEPT:

  1. Harbors periodontal pathogens
  2. Protects the host from oral infections
  3. Contains virulence factors causing tissue destruction
  4. Produces acids that demineralize enamel
Show answer and explanation

Correct answer: B. Protects the host from oral infections

Dental plaque is PATHOGENIC — causes caries and periodontal disease. It does NOT protect the host. SALIVA protects the host (sIgA, lysozyme, lactoferrin, buffering capacity).
