Laser Cavity Detector

Diagnodent: Advanced device for detecting decay

The Diagnodent can find cavities that other dental instruments can miss.

The device is designed as an adjunct to a traditional oral examination in the detection of  decay. Teeth that are suspicious for decay are ideal candidates for survey with the device.

Key Benefits:

  • Ability to locate decay in it's earliest stages.
  • Early detection means smaller cavities and smaller fillings.
  • Over 90% accurate!
  • Earlier treatment often means no anesthesia needed to fix teeth.


What is Diagnodent?

Diagnodent is a pen-like probe that sends a safe, painless laser beam into the tooth. A numeric display & alarm signals when there are signs of hidden decay.

How does diagnodent work?

  • The Diagnodent device measures laser fluorescence within the tooth structure.
  • As the incident laser light is directed into the tooth, two-way hand-piece optics allows the unit to simultaneously quantify the reflected laser light energy.
  • At the specific wavelength that the device operates (655 nm), clean healthy tooth structure exhibits little or no fluorescence, resulting in very low scale readings on the display.
  • Decayed tooth structure exhibits fluorescence, proportionate to the degree of decay, resulting in elevated scale readings on the display.
