Types Of Dental X-Rays

Types Of Dental X-Rays

X-rays, likewise called radiographs, are a crucial part of any dental care treatment plan. They are diagnostic, however they can also be preventive, by helping a dental expert diagnose prospective oral care issues in a patient’s mouth before they become a major issue.

What X-Rays Show

Intraoral X-rays are the most common kind of radiograph taken in dentistry. They provide a high level of detail of the tooth, bone and supporting tissues of the mouth. These X-rays enable dental professionals to:

  • Discover cavities
  • Look at the tooth roots
  • Check the health of the bony area around the tooth
  • Help diagnose gum disease
  • See the status of establishing teeth

Main Types of X-Ray Technology Used in Dentistry

X-rays are divided into two primary categories, intraoral and extraoral. With intraoral X-rays, the X-ray film is inside the mouth. With extraoral X-rays, the film is outside the mouth.

Intraoral Radiographs

Intraoral X-rays are the most common type. They offer a high level of detail. These X-rays allow dental practitioners to:

  • Find cavities
  • Look at the tooth roots
  • Check the health of the bony area around the tooth
  • See the status of developing teeth
  • Otherwise keep track of great tooth health

The different types of intraoral X-rays reveal various elements of the teeth:

  • Bite-wing X-rays (right)

highlight the crowns of the back teeth. Dentists take one or two bite-wing X-rays on each side of the mouth. Each X-ray shows the upper and lower molars (back teeth) and bicuspids (teeth in front of the molars). These X-rays are called “bite-wings” since you bite down on a wing-shaped device that holds the film in place while the X-ray is taken. These X-rays help dental experts discover decay between back teeth.

  • Periapical X-rays (left)

Emphasize only one or two teeth at a time. A periapical X-ray looks much like a bite-wing X-ray. However, it reveals the whole length of each tooth, from crown to root. Depending on your oral health and dental history your dentist may recommend a full-mouth radiographic surveya, or FMX. This includes every tooth, from crown to root to supporting structures. They are X-rayed using both bitewing and periapical radiographs.

  • Occlusal X-rays (right)

Are larger than many X-rays. They highlight tooth advancement and positioning in children. Each X-ray reveals nearly the full arch of teeth in either the upper or lower jaw.

Extraoral Radiographs

Extraoral X-rays are made with the film outside the mouth. These can be considered the “big picture” X-rays. They reveal teeth, but they likewise supply information on the jaw and skull. Extraoral radiographs are used to:

  • Keep an eye on development and development.
  • Look at the status of affected teeth.
  • Examine the relationships between teeth and jaws.
  • Examine the bones of the face.

Extraoral X-rays are less detailed than intraoral X-rays. For this factor, they are typically not used for spotting cavities or flaws in private teeth.

Scenic X-raysshow the entire mouth on a single X-ray. They consist of all teeth on both upper and lower jaws. This kind of X-ray requires an unique maker. The tube head that emits the X-rays circles behind your head while the film circles throughout the front. That method, the complete, broad view of the jaws is recorded on one film. Since the maker moves in a set path, you have to be positioned thoroughly. Devices attached to the X-ray machine hold your head and jaw in location. All this may look and feel intimidating, however the process is really safe. It often uses less radiation than intraoral X-rays.

Cephalometric projectionsare X-rays taken of the whole side of the head. They are used to take a look at the teeth in relation to the jaw and the person’s profile. Orthodontists use cephalometric forecasts to identify the best type of orthodontic treatment.

Cone-beam computed tomography (CT) provides three-dimensional images. You stand or sit while the device turns around your head. The beam is cone-shaped, rather of fan-shaped as in a standard medical CT. A cone-beam scan uses less radiation than a medical CT scan but even more than any basic dental X-ray. The cone-beam CT is especially beneficial for dental implant selection and placement.

Requirement computed tomography (CT) typically need to be done in a radiologist’s workplace or a health center. Normally, you will rest while the image is taken. The radiation exposure is greater for this type of CT than for a cone-beam CT. A basic CT scan might be done to figure out size and positioning location for implants.

Digital Radiographs

Digital radiographs are among the newest X-ray techniques. Requirement X-ray film is changed with a flat electronic pad or sensing unit. The image goes into a computer, where it can be viewed on a screen, stored or printed out. Digital X-rays taken at different times can be compared using a process that highlights differences between the images. Tiny modifications therefore can be caught earlier. Used effectively, digital X-rays use about half the radiation of conventional film.
