Visual differentiation between infected carious dentine & sound, re-mineralizable dentine by its ability to selectively dye the carious dentine

• Dark green color dye provides a strong contrast with both dentine and the pulp
• Stains outer infected dentine only
• Does not stain uninfected (affected) dentine
• Detects caries in difficult to see places
• Propylene glycol based formulation is more accurate than water based formula
