ICON Caries Infiltration

ICON Caries Infiltration



Icon is a light-curing, low-viscosity-based methacrylate-based plastic, e.g. TEGDMA for minimally invasive caries therapy¹.


  • Sealing of tooth decay and thus halting progression.
  • There are "ICON approximal" and "ICON vestibular".


  • Material is not X-ray opaque, for this an icon pass is required.
  •  Not repeatable at will.
  • High-quality overlay-free bite wings needed for assessment.


  • Carious lesion up to max. in outer dentin wall (D1) without cavitation.


  • Inactive carious lesions.
  • caries profunda.
  • Carious lesions with cavitation.
  • Root caries.
  • Developmental defects.
  • Erosions.

Infiltration steps¹

  1. ICON Etch (HCl) Hydrochloric acid for 2 min to disturb the pseudo intakt surface ( see Enamel Caries ), then spray 30 sec.
  2. Dry.
  3. Apply ICON Dry (ethanol) for 30 sec.
  4. ICON infiltrant (high liquid plastic) for 3 min.
  5. Light curing for 40 sec.
  6. Again ICON infiltrant for 1min.
  7. Light curing 40 sec.
  8. Remove surpluses.
