An old patient and has skeletal disorder by using x-ray found enlargement in.. What’s the type of x ray should be more accurate:
a- Cephalometric ***
b- Reverse town.
c- Panoramic x-ray.
---------------------------
Cephalometric X-ray is a unique tool that allows the dentist to capture a complete x-ray image of the face. X-rays in general provide the dentist with a way to see the teeth, jaw and soft tissues beyond what can be seen with the naked eye. Cephalometric X-rays are extraoral, which means that no plaque or film is inserted into the mouth. Cephalometric and panoramic radiographs show the nasal and sinus fossae that are not revealed by interproximal intraoral X-rays.
Cephalometric X-rays are usually performed with a panoramic X-ray machine. The adapted device will have a special cephalometric film holder attached to a mechanical arm. A radiographic image receiver is exposed to ionizing radiation to provide the dentist with pictures of the entire oral structure. The advantage of cephalometric and panoramic X-rays is less exposure of the body to radiation.
Cephalometric X-rays are not as common as complete or interproximal X-rays, but they perform several important functions:
- Provide views of the lateral profile of the face.
- Provide views of the jaw with respect to the cheekbones.
- Provide information on "bad occlusions" or malocclusions.
- Allow the measurement of teeth.
- Determine fractures and other injuries to the teeth and jaw.
- Assist in the planning of orthodontic treatments.
How are cephalometric radiographs performed?
Cephalometric X-rays are completely painless. The head is placed between a rotating mechanical arm and a film holder which is installed on another arm. The arm turns around the head to capture images of the face, mouth and teeth. The clarity and sharpness of these images depend on the position of the body. Images are usually enlarged by up to 30% so that any signs of deterioration, illness or injury can be perceived and treated.
After taking cephalometric X-rays, the dentist will see the complete profile of the side of the head. This can help plan an orthodontic treatment and allow an immediate assessment of how the orthodontic appliance will affect the profile of the face and teeth. Another common use of this type of X-ray is to determine specific measures prior to the placement of dental implants.
