Innovative caries detection

The Facelight light probe enables you to proceed selectively during caries excavation.
This is supported by the innovative FACE method:
Fluorescence Aided Caries Excavation

  • Light probe shining

    How Facelight works

    Bacteria in dentine infected by caries leave behind metabolic products (porphyrins). When an exposed cavity is illuminated with violet light (wavelength
    of 405 nm), these porphyrins show a red fluorescence, thereby indicating the significant areas for caries excavation.

    Your advantages at a glance

    • Visual detection of caries in opened cavities
      at a glance
    • Support for the selective, minimally invasive excavation
    • Safety and minimal risk of caries recurrence
    More reliable caries detection

    More reliable caries detection

    An examination with Facelight minimises the risk of recurrence of caries.
    The Facelight light probe also provides important information for deciding how to treat Caries Profunda.
    The slender design of the Facelight light probe offers optimum access to the treatment site.
    Flexible, non-contact and therefore painless application is guaranteed.

    Without Facelight

    Bacteria in dentine infected with caries leave metabolic by-products (porphyrins). They are not visible to the naked eye.

    With Facelight

    Dentine infected with caries is clearly visible in opened cavities when illuminated
    with the Facelight light probe. The porphyrins present there fluoresce red,
    while healthy tooth substance fluoresces green.
    The Facelight diagnostic goggles increase the contrast.

    Supports minimally invasive procedures

    Supports minimally invasive procedures

    With the Facelight light probe you can precisely excavate dentine infected with caries.
    This conserves the healthy tooth substance of your patients!

    Facelight aids detection and monitoring of carious tooth substance, in particular in dentin, during the excavation
    of previously opened cavities.
