The NCCT method is non- contrast computed tomography method of analyzing the mandible.
The NCCT helps a patient and the doctor to identify the possible malfunction of the mandible. It uses the ionizing radiations to develop a picture of the internal organs. The cross-sectional images help in determining the cause of unexplained pain, a source of inflammation, and injuries. This method does not use a contrast dye. It is useful for patients allergic to contrast dyes. It employs to detect the presence of malformation in the mandible that may lead to hemorrhage in certain cases. 
NCCT is a non-invasive, simple, and easy method to perform.
- Make the patient comfortable on the scanning table.
- A sedative for claustrophobic patients may be given.
- Keep other body parts covered by a lead covering.
- The X- rays take pictures from various angles.
- These pictures may combine in the end to give a three- dimensional picture.
NCCT usually does not consume a lot of time.
Risks associated with NCCT due to the X rays are:
- The radiologist exposes the patient to a high amount of radiations.
- The radiations may cause cancer after repeated performances.
- The radiations may bring harm to the fetus.
Prior preparation includes:
- Remove any jewelry and accessories from the body.
- Do not consume food and water a few hours before the scan takes place.
- Wear a comfortable loose gown for the test.
- The patient should inform the doctor about any allergies or certain medicine intakes.
- Women with a developing fetus should not undergo NCCT.
After the test, the patient can return from the hospital on the same day.
- Follow the instructions provided by the doctor after the test carefully.
- Take the medicines regularly as told by the doctor.
- Resume a normal diet and activities.
