(Dental X- Ray)

Part 1

Dental X-ray plays an important role in diagnosis of disease, treatment of disease and evaluating the severity of problem. It helps dentist to visualise the disease of teeth, and surrounding tissue than cannot be seen in normal oral examination.

  Dental X-ray (radiograph) are image of your teeth and surrounding hard tissue that a dentist uses to evaluate oral health. These X-rays are used with low level of radiation to capture image of your teeth and surrounding hard tissue.

What Problems Can Dental X-Rays Detect?

In adults, dental X-rays can be used to:

•  Show areas of decay that may not be visible with an oral examination, especially small areas of decay between teeth.

•  Identify decay occurring beneath an existing filling.

•  Reveal bone loss that accompanies gum disease.

•  Reveal changes in the bone or in the root canal resulting from infection.

•  Assist in the preparation of tooth implants, braces, dentures, or other dental procedures.

•  Reveal an abscess (an infection at the root of a tooth or between the gum and a tooth).

In children, dental X-rays are used to:

•  Watch for decay.

•  Determine if there is enough space in the mouth to fit all incoming teeth.

•  Determine if primary teeth are being lost quickly enough to allow permanent teeth to come in properly.

•  Check for the development of wisdom teeth and identify if the teeth are impacted (unable to emerge through the gums).

•  Reveal other developmental abnormalities, such as cysts and some types of tumors.
