A comparison of antimicrobial activity of four disclosant dyes.
Four disclosant dyes were tested for antimicrobial activity against 27 oral reference strains and five non-oral human pathogens. Erythrosine and fluorescein inhibited most gram-positive and gram-negative organisms associated with dental plaque, and were bactericidal to selected strains. Fast green and brilliant blue demonstrated little antimicrobial activity.
