  2. Execution: The expert will then take the radiograph of the area or part he needs. It is a short and painless process that can be repeated until the images of all the areas of the mouth are necessary. This can be printed on a photographic paper or viewed by means of a computer

Importance of dental radiographs

Dental radiographs are images of the teeth and maxillofacial structure that are obtained through the use of x-rays. These are composed of electromagnetic waves that have the ability to pass through opaque bodies such as bone structure and form images. The color of the elements in the image depends on the composition of each of them. Structures that have air will appear black in print, while woven and liquid teeth will have a gray hue.

What are dental x-rays for?

Dental radiographs complement any clinical evaluation that the specialist performs on the patient. They are useful in virtually all stages of many mouth treatments. It is a tool that helps diagnose the problem more specifically. And it is also an important part in the preparation of the treatment planning indicated for the patient.

Types of dental radiographs

There are several types of dental radiographs and each of them allows the specialist to evaluate different elements of your mouth.

Depending on the position of the device

  • Intraoral: Are those where the film is placed in the inner part of the mouth, as in the bite fin radiography.
  • Extraoral: In this type of dental x-ray the film is placed on the outside of the mouth.

According to its function:

  • Interproximal: This type of radiography is also known as the bite fin. In it you can see the teeth of a specific area of ​​the mouth seen from the side. The image also distinguishes the dental roots and the bone that supports them. The film is placed inside the mouth so it is intraoral. This is mainly used to detect cavities that are between the teeth or in areas difficult to evaluate with common tools. Although it can also be used to assess the state of bone supports.
  • Periapical: In it you can observe all the elements of the tooth, from the crown to its root. It can be one or two specific pieces. The image provided by this study allows specialists to determine if there is any change in the root or structures surrounding the bone.
  • Panoramic: It allows to visualize the mouth in its entirety. This type of x-ray is used to observe the position of erupted teeth, those that are in the eruption phase and those that are impacted. To carry out this image you need a special machine that rotates around the patient’s head.
  • Occlusal: It is also known as palatal. Through this type of x-ray they can observe an entire arch of teeth. It is usually used in children to see the development of their jaw.
  • Complete: This dental x-ray is a set of those already named. It is used when the specialist does not have any information about the patient’s condition. Also, in case you present a history of mandibular pathologies.
