X-Rays Used in Dentistry

X Rays are widely used in dentistry for:

  • Accessing the depth of cavity or teeth decay
  • Examining the root and surrounding bone
  • Checking for abnormalities
  • Checking the development to teeth
  • General study of teeth and bone structure

Types of X-Rays used by Dentist

Panoramic
Shows a view of the teeth, jaws, nasal area, sinuses and the joints of the jaw, and is usually taken when a patient may need orthodontic treatment or implant placement.

CBCT

Less radiation CT of the skull. The machine is incorporated in the simple full mouth xray (OPG) machine – so the patient does not have to be subjected to the claustrophobic experience of the normal CT procedure. It is taken in minutes and the patient just needs to stand/ sit – so it gives the perfect view of the soft tissues. It helps the patient and the doctor visualise the jaw bones and the teeth 3 dimensionally. More accurate and detailed than a CT scan. The treatment for procedures like IMPLANTS can be virtually planned and executed meticulously without human error. Dimensionally more accurate and detailed than a CT scan.

TMJ-TOMOGRAM

Quite similar to CT scan where the jaw and skull joint problems can be clearly visualized.

INTRA ORAL-PERIAPICAL RADIOGRAPH/ RVG

Digital x ray of the tooth that can be viewed on the computer screen, shared and stored in kilobytes and not on perishable films.

LATERAL CEPHALOGRAM

Side profile x ray of the skull and soft tissues and is used to take various measurements to determine and assess the current and future relationship of the upper and lower jaw and assess your bite.

Bite-Wing
Offers a visual of both the lower and upper posterior teeth. This type of X-ray shows the dentist how these teeth touch one another (or occlude) and helps to determine if decay is present between back teeth.

Occlusal
Offers a clear view of the floor of the mouth to show the bite of the upper or lower jaw. This kind of X-ray highlights children’s tooth development to show the primary (baby) and permanent (adult) teeth.
