Q

Detecting dental biofilm

A
  • dental biofilm is not usually visible by the naked eye
  • only visible by naked eye if there’s an abundance of it (usually along the gingival margin and inter-proximal areas as stagnant areas where this isn’t natural cleaning or shedding forces of movement of oral mucosa)

-if not visible by the naked eye use disclosing agents to detect even a small amount as it can increase risk of periodontal disease and gingival inflammation

Q

How to apply disclosing agent to patients

A
  • ask patient to gently rinse mouth to remove materia alba
  • apply different disclosing solutions (can be liquid, or tablets)
  • ask patient to gently to rinse again → any substances retained on surface but not bound onto dental biofilm will be rinsed off
  • then proceed with dental biofilm identification
