A Thing Or Two About Dental Sensors

Dental sensors are used by many dentists worldwide in order to better diagnose a patient's condition

. This device mostly uses x-rays, much like other imaging techniques for hard tissue like bones or teeth. Since you can not use a full sized x-ray to properly image the oral cavity, this means that a device which is tailor-fit for the application must be used. In addition, using x-rays will need a radiologist, and for most cases, this will be relatively impractical.

Most of these devices are still analog, although digital imaging devices are also being used in order to make the analysis of the images faster. Plus, going digital would mean that the image will be shown near-instantaneously, as opposed to the manual method where you still have to wait for the film to develop. Sometimes, however, ultrasound and other frequencies may be used, especially if trying to diagnose gum diseases, like gingivitis.

The form factor of the sensor is also the main differentiating feature of these kind of imaging device. Since dentistry is the care of the oral cavity and the oral cavity is relatively particular when it comes to imaging, a special shape and ergonomic design was used. Most of these sensors are hand-held and are smaller than a person's head. This means that they can be simply pressed near your cheekbones and will give the image that is needed for diagnosis.

More advanced programs can also extend the capabilities of the sensor for dental applications. Some may be able to integrate different images into a three dimensional image. This allows the dentist to view the oral cavity at any angle he or she wishes to, making prognosis faster and more accurate. In addition, it also allows the dentist to further visualize the cavity, allowing him or her to check any angle he or she may have missed with conventional imaging.

Detail is also a crucial factor in determining the imaging set you wish to procure. Generally, the more detailed the picture is, the better it will be. This also affects how much you can zoom the image, since too much zooming will cause artifacts to be shown. These artifacts are objects which do not really exist but are visible in the image. This may be mistaken for features, and will lead to an inaccurate diagnosis.

Dentistry sensor appliances are an indispensable part of modern dentistry and its practice. It makes a dentist's work easier by showing the oral cavity and the problem site at every possible angle. It makes the profession better for the patient.
