Laser Decay Detection

The KaVo DIAGNOcam reveals a whole new perspective on tooth decay and cavities.  It is a laser device that helps the dentist detect the presence of tooth decay in its earliest stage. Tiny lesions are detected before they even have a chance to pose a problem.

We can help to safeguard and preserve your tooth substance while providing you with the earliest possible care. Promising early cavities detection, the DIAGNOcam also allows your dentist to use the latest techniques for restoring teeth.

How does it work? 

KaVo DIAGNOcam uses the structures of the tooth as light conductors. Simultaneously, a digital video camera, captures the context.

The device emits a pulsed beam of a defined wavelength that is directed onto the tooth. The presence of a tooth decay stimulates an altered wavelength of the fluorescent light, which DiagnoDent picks up as an acoustic signal. The wavelength is then interpreted by the electronic system in the KaVo DiagnoDent control unit, which in turn produces a numerical reading. The laser device can detect cavities smaller than the tip of a dental explorer, the typical probe used prior to advent of laser cavity diagnosis.

What are the benefits of laser decay detection?

Besides detecting the minutest problems at a very early stage, the DiagnoDent unit also has the following benefits: Improves diagnostic in the fissure area (“valleys” in the tooth); monitors caries and their development; affords minimally invasive treatment; preserves healthy tooth substance; improves preventive therapy; and increases patient confidence.

When decays are detected and treated earlier, the dentist will be able to prevent new decays from developing into complicated dental problems, thus saving the patient time and money in the long run.

What is a typical procedure like?

The device would be calibrated prior to the start of the diagnosis. After the teeth have been cleaned, they are scanned using the laser beam emitted by the device. If there are caries present, the handheld laser diode would locate and identify the problem area and send the information back to the attached countertop unit, which would then produce a read-out in digital form. The amount of fluorescent detected would allow the dentist to ascertain the degree of the decay.

The cavity diagnosis procedure is painless, exerting a tiny energy level akin to that produced by a presenter’s laser pointer. The laser beam does not in any way harm the soft tissues in the mouth.

Does DiagnoDent work on milk teeth?

Yes. The device provides an accurate reading detecting cavities in both primary and permanent teeth.

Aren’t dental probes and X-rays enough to detect cavities?

Although the fluoride ingredient in toothpastes and water has strengthened the teeth enamel and made them more resistant to decay, it fails to offer effective protection for the pits and valleys. The use of conventional diagnostic tools like x-rays may not offer sufficient coverage to detect cavities in these regions when they are hidden from specific angles of views.

It should be noted, however, that while DiagnoDent is used to find cavities on the teeth surface, X-rays are able to probe deeper on the roots as well as in between teeth.

Whether due to the location or size of the cavity, dental probes may too bulky to detect certain cavities. In particular, cavities detection in pits and fissures is difficult because tooth surface often appears intact. The DiagnoDent’s laser provides pin-point accurate evaluation of the tooth’s actual condition, even where conventional techniques may be unable to detect the newly formed and tiny cavities.
