What is a dental x-ray?

Almost every time we go to the dentist they ask us to take a radiograph, and because these are an essential part in dentistry, allowing see in places where the human eye is unable to do so. We will tell you more about X-rays, the rates of these exist, and their uses are given in the dental office.

X-rays are used to diagnose problems in oral health, which are required before starting any treatment; but these are required for some treatments to ensure a good result, for example for endodontics .

What are the different types of X-rays and what show?

Basically, dental, x-rays can be divided into two categories: intraoral X-ray, and extra oral X-rays. Below we will explain each category and its subdivisions.

The intraoral X-ray

These, as the name implies, are X-rays in which the film is put into the mouth to take pictures of the teeth and supporting structures. These X-rays are the most common type in the dental area and show small areas in great detail. They help the dentist to look for signs of possible tooth decay and gum disease or check the health of your teeth, or any treatment that has been done before, and ensures that all is well.

The main types of intraoral X-rays corresponding to different points of view, providing various information. Here we tell you what:

  • Bite Wing

In this ray bite wing the patient has to bite a stand that could be messy, depending on the size of the mouth, but only for a few seconds. This film shows the crowns of the posterior teeth and the upper of this supporting bone, showing the top and bottom of one side. This view is used in routine checkups because it allows diagnose cavities and between the teeth; decay around existing fillings; overhanging margins of fillings; the goodness of fit of crowns and bone loss if you suffer from periodontitis.

  • Periapicales

This view shows the entire tooth in question, including the crowns, roots and surrounding tissues. It is useful in diagnosing problems involving the nerve of the tooth, periodical abscess, periodontitis severe (when bone loss); also needed for a procedure root canal, or to evaluate before extraction.

  • Oclusales

These are taken rarely, but can be useful to help locate impacted or in cases of trauma teeth. Is larger x-ray showing most of the arch of the teeth, either in the upper or lower jaw.

The extra oral X-ray

These x-rays, unlike previous ones, correspond to the film gets out of the mouth. Generally used to display images of the skull, face and jaws. It is a general view of all teeth, which delivers no detail on intraoral radiographs. They are useful for monitoring the growth and development of teeth and jaws, assessing bone levels, to see the growth and direction of the wisdom teeth (and other teeth). They are also used for evaluation of dental implants.
These films have different views, and each serves a different matter. Then we will show the two most common:

  • Panorama

This film shows the entire upper and lower jaw. Through this clearly shows the location of the inferior alveolar nerve, which supplies sensation to all lower teeth and lower lip. This is important when evaluated for the extraction of wisdom teeth, because the roots can be found close to this nerve may be damaged. As shown the bone supporting the teeth, this radiograph is useful to assess the severity of periodontitis in the entire mouth, allowing detailed monitoring of the levels of bone.

  • Cefalométrica lateral

This radiograph usually orthodontic treatment is used; it shows the face, jaws and teeth from the side profile. There are standard features that are evaluated by observing through this radiograph, the angles that are applied to the teeth and jaws.

Thus, the normal range compared to a good diagnosis, treatment planning and monitoring. One cephalostat is used to ensure that the image can be accurately reproduced for comparative purposes, and changes in the position of the teeth can be monitored.
