Diagnodent for detecting decay and caries

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 occlusal decay. Teeth that are suspicious for caries are ideal candidates for survey with the device
Key Benefits:

  • A laser examination tool for the early detection of caries.
  • Even very small lesions can be detected at the earliest stages.
  • Over 90% accurate!
  • Earlier treatment - Better outcomes

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 propagated into the site, 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.
  • Carious tooth structure exhibits fluorescence, proportionate to the degree of caries, resulting in elevated scale readings on the display.

Over 90% accurate!

Proportion of "correct diagnoses" using various diagnostic methods (in the case of seemingly intact occlusal - biting surfaces).

In a study conducted by Dr. Lussi of Berne University, Switzerland, dentists correctly diagnosed hidden fissure areas by visual inspection in only 57% of all cases.

diagnodent study

The same group achieved an impressive success rate of 90% with the DIAGNOdent. In fact, DIAGNOdent was far more accurate than any other method in the study including bitewing x-rays (flossing x-rays) .
