RADIOLOGY

WORLD CLASS IMAGING & DIAGNOSTIC INFRASTRUCTURE AT FMS

RVG – 2D DIGITAL INTRAORAL IMAGING

Radiovisiography  is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.

Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, as well as the ability to apply special image processing techniques that enhance overall display quality of the image.

Extraoral 2d Digital Imaging

Extraoral x-rays are used to detect dental problems in the jaw and skull. There are several types of extraoral x-rays.

  • Panoramic x-rays show the entire mouth area — all the teeth in both the upper and lower jaws — on a single x-ray. This x-ray detects the position of fully emerged as well as emerging teeth, can see impacted teeth, and help diagnosis tumors. . Panoramic image is a starting point of many treatments and further imaging tasks.
  • Cephalometric projections show an entire side of the head. This x-ray looks at the teeth in relation to the jaw and profile of the individual. Orthodontists use this x-ray to develop each patient’s specific teeth realignment approach.

CONVENTIONAL INTRAORAL X-RAYS

These are the most common type of x-rays. There are several types of intraoral x-rays. Each shows different aspects of teeth.

  • Bite-wing x-rays show details of the upper and lower teeth in one area of the mouth. Each bite-wing shows a tooth from its crown (the exposed surface) to the level of the supporting bone. Bite-wing x-rays detect decay between teeth and changes in the thickness of bone caused by gum disease. Bite wing x-rays can also help determine the proper fit of a crown (a cap that completely encircles a tooth) or other restorations (eg, bridges). It can also see any wear or breakdown of dental fillings.
  • Periapical x-rays show the whole tooth — from the crown, to beyond the root where the tooth attaches into the jaw. Each periapical x-ray shows all teeth in one portion of either the upper or lower jaw. Periapical x-rays detect any unusual changes in the root and surrounding bone structures.
  • Occlusal x-rays track the development and placement of an entire arch of teeth in either the upper or lower jaw.
