When hydrofluoric acid contacts enamel during porcelain repair procedures, formation of calcium fluoride occurs and bond strengths to enamel drop significantly. 2 Therefore, it is vital to treat porcelain and tooth structure separately with appropriate acids. EtchArrest isolates hard and soft tissues when rubber dam placement is not practical.
  • Neutralizes acid etchants upon contact
  • Protects soft tissues and adjacent restorations
  • Appears visible against tissues and acid etching agents
