By precisely staining only carious dentin or enamel Caries Finder dye ensures conservative caries removal. It reduces the possibility of inadvertently leaving carious dentin or of removing excessive dentin. Caries Finder will not stain the following materials:
• Normal healthy dentin.
• Inner carious dentin (uninfected) with solid collagen fibers.
• Normal healthy enamel.
Since Caries Finder only stains the denatured collagen fibers of infected dentin, healthy and remineralizable dentin is easily differentiated. It saves time by identifying incipient lesions, dentin caries, decay in undercuts and lesions with limited view or access. It is especially useful where pulp exposure is expected by indicating where excavation should stop.
