Importance of X-ray screening

Dental X-rays are taken using a special machine called a dental radiographer.

This machine emits a small amount of ionizing radiation that passes through the soft tissues of the mouth and captures images of the inner layers of the teeth and jaws.

These images are then analyzed by your dentist to detect any problems.

Types of dental X-rays

There are several types of dental X-rays, including panoramic X-rays, which can be used to see all the teeth in the mouth in one image; periapical X-rays, which are used to see the areas around the roots of the teeth; and bitewing X-rays, which are used to see the top and bottom of the teeth at the same time.

Importance. Role

Check radiographs are important for several reasons. First, they allow dentists to detect problems that might be invisible during a physical examination, such as tooth decay or root problems.

This means that these problems can be treated at an early stage, which can reduce the risk of tooth loss or other complications.

Secondly, follow-up X-rays allow dentists to monitor the progress of dental or maxillofacial problems.

For example, if a patient has a root canal condition, follow-up X-rays can be used to monitor its progress and determine if treatment is effective or if changes are needed.

Finally, follow-up X-rays are important to help dentists plan treatment.

They can provide essential information about the structure of the teeth, jawbones and surrounding tissues that is needed to plan treatments such as dental implants, dentures or oral surgery.

However, it is important to bear in mind that dental X-rays involve exposure to ionizing radiation, which may pose a certain health risk.

Dentists should therefore be selective in their use of dental X-rays and ensure that they are only used when necessary.

Imaging in dentistry – Cone beam computed tomography (CBTC)

Taking radiographs is an important step in the planning of treatment.

In modern dentistry no medical procedures are performed without at least one radiograph.

This way, details that escape clinical examination can be seen.

Also, bone and root changes can only be observed by additional means.

Dental radiography, in addition to its role in directing the treatment plan, also has a role in checking the results and monitoring progress.

Recently, CBCT is of great importance, as it is an imaging method that is increasingly used, with an accuracy far superior to conventional radiographs.

Perhaps for some patients, CBCT is a completely new element. That’s why we’ll explain at length what it means, what it’s for and why it’s better than traditional X-rays.

  • CBCT stands for cone beam computed tomography. The technology emerged in the early 2000s and is now widely used, with the merit of improving diagnosis and treatment modalities, at affordable prices and low radiation doses.

  • The machine used to perform CBCT is in the same shape as the one used for panoramic X-rays, so it is comfortable for the patient, who does not have to occupy uncomfortable positions. The CBCT machine uses a conical beam of rays, as its name suggests, and scans an area precisely indicated by the dentist. This area can be a hemi-arch, a sector or the whole arch as a whole.


Unlike traditional panoramic or retro alveolar dental X-rays, a CBCT allows more data to be obtained and the software used to visualize the data also allows changes to be made, which are useful in drawing up a treatment plan:

  • Very precise measurements of bone height, thickness or width. On conventional X-rays, only the height of the bone can be assessed.

  • Taking sections in any axis, particularly useful in implantology

  • Determination of bone density, of real importance in implantology. This measurement cannot be assessed on traditional radiographs.

  • Making changes to parameters such as brightness, contrast or size, allowing the doctor to observe the anatomy of certain structures more accurately, in order to avoid them and reduce the risk of complications.

  • Preconfiguring the areas where implants can be inserted

Whenever the doctor needs reliable three-dimensional measurements, CBCT examination proves indispensable.

The use of panoramic radiography alone for complex treatments only increases the risk of touching structures that should normally be avoided or may lead to errors in measurements.

The end result may be compromised if precise imaging methods and careful planning are not adhered to.

CBCT as an imaging method successfully meets the demands of the physician. It also offers excellent results at affordable prices but also through examination methods that are convenient for the patient.

CBCT is a modern method and with its advent in the 2000s, therapeutic success rates have increased dramatically.

Control radiography is an essential tool in dentistry, allowing dentists to assess and diagnose dental and maxillofacial problems.

They are used to detect cavities, root problems, bone problems, tumors and other problems that might be invisible on physical examination.

In conclusion, radiographs are an essential tool in dentistry, allowing dentists to detect and diagnose dental and maxillofacial problems, monitor their progress and plan the necessary treatments.

However, it is important to bear in mind the risks associated with the use of dental X-rays and to use them only when necessary.
