Typical extraoral x-ray images include panoramic, cephalometric and cone beam computed tomography (CBCT) projections. A lateral cephalograph is a sagittal projection of the skull that includes both the hard and soft tissues.
Similarly one may ask, what are extraoral radiographs?
There are two main types of dental X-rays: intraoral (meaning the X-ray film is inside the mouth) and extraoral (meaning the X-ray film is outside the mouth). Extraoral X-rays show teeth, but their main focus is the jaw and skull.
Beside above, what is a full mouth series? Full mouth series A full mouth series is a complete set of intraoral X-rays taken of a patients’ teeth and adjacent hard tissue. This is often abbreviated as either FMS or FMX (or CMRS, meaning Complete Mouth Radiographic Series).
Consequently, what are the three types of dental images?
There are three types of diagnostic radiographs taken in today’s dental offices — periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric. Periapical radiographs are probably the most familiar, with images of a few teeth at a time captured on small film cards inserted in the mouth.
What two planes are used to position the patient to take extraoral radiographs?
Panoramic radiography. There are four basic anatomical planes used to properly position a patient: the ala-tragus plane, orbital/meatus plane (the Frankfort plane), canine/meatus plane, and median sagittal plane. Devices for positioning the head and supporting the chin are also important for precise positioning.

What is bitewing technique?
Bitewing Technique The bitewing radiographic image is used to examine the interproximal surfaces of the teeth and is particularly useful for the detection of dental caries and alveolar bone levels. The receptor is placed into the mouth parallel to the crowns of the maxillary and mandibular posterior teeth.
Can dental Xrays show nerve damage?
When an impacted tooth is suspected, its presence and position in the bone can be confirmed through a dental radiograph. A dental x-ray takes images not only of the teeth but also of the adjacent structures such as nerve canals and sinus spaces.
How many teeth do we have?

How do they XRAY your teeth?
This technique involves biting down on a special piece of paper so that your dentist can see how well the crowns of your teeth match up. This is commonly used to check for cavities between teeth (interdental). Occlusal. This X-ray is done when your jaw is closed to see how your upper and bottom teeth line up.
What is a focal trough?
The three-dimensional, horseshoe-shaped zone where images are sharp is called the focal trough, or image layer. The panoramic radiograph is composed largely of the anatomic structures located within this focal trough. The focal trough is the area in which structures will appear most sharply and clearly.
