Laser Cavity DX

Laser Early Cavity Diagnosis . . .

More and more patients place value on healthy and attractive teeth. In order to maintain them, the earliest possible care is essential. DIAGNOdent helps you with early detection. Even very small lesions are detected at the earliest stage, enabling you to protect and preserve the tooth substance.

The Kavo DiagnoDent is a laser device which enables us to detect the presence of dental decay in its earliest stage.

We used to detect cavities with a sharp explorer-probe. The cavity had to be larger than the size of the tip of the explorer before we could detect it. This was okay because we used to prepare cavities with a drill. The cavity had to be bigger than the size of the head of the drill bit. Now, with the newer laser technology and air abrasion technology, we can prepare a very small filling for a very small tooth decay. We need a better and more sensitive device to detect tooth decay. The DiagnoDent emits a laser beam to the tooth. If there is dental decay, the fluoresence would be an altered wavelength, with in turn would be sensed and interpreted by the DiagnoDent to give out a numerical reading. With the DiagnoDent, we can now detect cavities smaller than the tip of a dental explorer.



How it works:

A laser diode provides pulsed light of a defined wavelength that is directed onto the tooth. When the incident light meets a change in tooth substance, it stimulates fluorescent light of a different wavelength. This is translated through the handpiece into an acoustic signal, and the wavelength is then evaluated by an appropriate electronic system in the KaVo DiagnoDent control unit.


  • Improved diagnostic in the fissure area
  • Caries – monitoring
  • Even the most minute problems are detected at a very early stage
  • Minimally invasive therapy permits adhesive bonded restorations of good appearance with tooth-colored composites
  • Appropriate preventive therapy
  • Healthy tooth substance is preserved
  • Increased quality of work due to optimum precision
  • Increased patient confidence
