Types Of Dental X-Rays

There are two main types of dental x-rays utilized for imaging: intraoral and extraoral. The most common are intraoral x-rays, which capture images of the inside of the mouth. Intraoral imaging helps to determine the health of the roots, cavities in the teeth, and evaluate the health of the bone and jaw. There are several types of intraoral x-rays, each capture different angles of the mouth:

Bitewing X-rays

Bitewing x-rays capture images of the upper and lower teeth in one distinct area of the mouth. It shows the crown of the tooth, to the level of supporting bone. This type of image is used to detect any decay in between the teeth or any deterioration of the bone.

Periapical X-rays

Periapical x-rays show the entire mouth, from the crown to where the root attaches into the jaw bone. These images are used to determine if there is any abnormal changes to the tooth root or surrounding bone.

Occlusal X-rays

Occlusal x-rays are a diagnostic tool used to track the development of the entire arch of the upper or lower mouth.

Extraoral imaging focuses on the bone and tissues of the skull and jaw. These images allow our specialists to view full images of the patient’s skull. Types of extraoral imaging include:

Panoramic X-rays

This type of imaging captures the entire mouth region in one single image. Panoramic x-rays are useful in detecting fully emerged, newly emerged, impacted teeth, and help diagnose tumors.

Dental Computed
Tomography (CT scanning)

This is a 3D image of the inside of the mouth to identify issues in the bone structure, such as tumors or fractures. They also help evaluate bone strength for the placement of dental implants and difficult extractions.

Cone Beam CT (CBCT)

Cone Beam CT scans provide high quality 3D images of the soft tissue, nerves, and bone. This type of imaging acts as a guide for dental implant placement, as well as can detect any complications in the gums, tooth root, and jaws.

Dental x-rays are typically performed during the initial exam. Depending on the issues or severity of the case, different types of images will be ordered in order to ensure a proper diagnosis. Combining both types of imaging, intraoral and extraoral, provides specialists with a comprehensive report on the current state of the patient’s mouth.

  • Any areas of tooth decay.
  • Bone loss caused by periodontal disease.
  • Changes in the root canal.
  • Abscesses, which are infections at the root of the tooth or between the tooth and gum.
  • Dental injuries or damage to the that supports the teeth.

Dental x-ray imaging is also used for treatment planning for cavities, root canal therapy, tooth extraction, and for the placement of dental implants.
The potential physical and environmental impacts of traditional film x-rays have long been the source of debate in every area of the health field. Unlike traditional film x-rays, our digital method reduces radiation exposure by up to 90%, making digital radiography the fastest, safest, and most precise type of imaging available. Due to the very minimal levels of radiation being exposed, the risk of potential harmful effects are very small. Dental x-ray techniques are designed to limit the body’s exposure to radiation and several precautionary methods are taken to ensure your safety and comfort. When performed with the proper precautionary techniques, there is very little cause for concern.
