  • Consists of 1% Acid Red solution in a propylene glycol solvent
  • Stains the loosened collagen fibers of outer carious dentin red, and inner carious dentin pink
  • Allows creation of a Peripheral Seal Zone (PSZ) and Caries Removal Endpoints (CRE) which therefore helps to preserve pulp vitality
  • Demonstrates the Hierarchy of Bondability (HOB)
