Two-tone disclosing agents are especially useful to:

• Differentiate stain origin

• Identify carious lesions

• Measure gingival crevice depth

• Evaluate salivary flow

An ideal disclosing agent should possess which property?

• High water solubility

• Permanent staining of enamel

• High systemic toxicity

• Unpleasant taste

• Limited shelf life

Disclosing agents aid in patient education by:

• Physically removing plaque

• Directly reducing gingival inflammation

• Highlighting areas needing improved hygiene

• Strengthening enamel resistance

• Acting as an antimicrobial rinse

After using a disclosing agent, the next step should be to:

• Isolate and etch enamel

• Perform scaling and root planing

• Perform gentle brushing and flossing
