Detecting the Invisible = Diagnodent

diagnodent_clip_image001Our continuing education has kept us at the forefront of current treatment modalities. We also believe that new arising technologies are
just as important to integrate into our high level of care. You may not realize it, but even the tiniest spot of decay can mean trouble for
your teeth. That is why we take such care to identify and fill cavities: it is the key to preventing all kinds of trouble down the road. We know that our patients place a high value on healthy and attractive teeth; in order to maintain them, the earliest possible care is essential. Our office has a simple, fast and painless examination using the DIAGNOdent, a harmless laser scanner that will help us with the early detection of decay. Even very small lesions are now detected at the earliest stage, enabling us to protect and preserve your teeth and smile. The DIAGNOdent laser cavity detection system is the most significant breakthrough in diagnosing tooth decay since the dental X-ray. With the widespread use of fluoride in both drinking water and toothpastes, it is much harder to detect tooth decay than ever before. This is because the fluoride hardens the enamel so that most decay starts in microscopic defects in the hard surface and can readily spread into the softer surface beneath. This destroys the tooth from the inside out.

The DIAGNOdent is a pen-like probe that sends a safe, painless laser beam into the tooth and checks its health. A number scale and an alarm will signal when there are signs of hidden decay. This allows us to determine if decay is lurking beneath the apparently healthy tooth surface. This technology allows us to catch tooth decay at an earlier stage, before the tooth is destroyed from the inside out. This will help prevent more extensive procedures.



The DIAGNOdent device measures laser fluorescence within the tooth structure where the probe cannot reach. The DIAGNOdent operates at a wavelength of 655 nm. At this specific wavelength, clean healthy tooth structure exhibits little or no fluorescence, resulting in very low scale readings on the display. However, carious tooth structure will exhibit fluorescence proportionate to the degree of caries, resulting in elevated scale readings on the display of the DIAGNOdent. As the incident laser light is propagated into the site, two-way handpiece optics allows the unit to simultaneously quantify the reflected laser light energy.

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.
