Dental X-rays are images of the teeth that we use to assess patients' oral health, in order to establish a correct diagnosis and a complete treatment plan.
Smile Vision Dental Centre is equipped with state-of-the-art dental imaging technology that reduces the risk of radiation to patients and provides clear and safe results in the shortest time.
It is important to know that all radiological examinations can be performed directly in our clinic, without the need to travel to other imaging centres.
What is radiology?
Dental radiology is the specialty that uses dental imaging in order to diagnose various dental conditions. Radiography (X-rays) is an imaging technique, part of radiology, represented in the form of a flat and three-dimensional image of teeth, jaws, soft tissues and bones following exposure to X-rays or digital scanning (digital radiology).
X-rays help the dentist establish an accurate diagnosis. The procedure reveals details that are used by the specialist to determine the nature of an intervention on the teeth and recommend a treatment plan.
Dental X-rays have a dual role. On one hand, this procedure answers dentists’ questions that arise when a simple consultation does not reveal all patient's problems; on the other hand, is an essential factor of prevention, because it reveals early diseases that need to be treated.
Types of X-rays provided
3D dental X-Rays
3D dental radiography is a non-invasive and painless method of capturing more details from hard-to-reach areas of the oral cavity and expressing them concisely, providing much more information than a regular examination. It is a brief procedure, with no impact on health, which offers a much more detailed view of the patient's teeth and bone density
At Smile Vision, we offer several types of 3D dental X-Rays:
- 3D endo X-rays
- Partial X-rays / arch
- Total 3D X-rays
The results of these X-rays are generated in 3D format, the information being therefore more detailed and accurate compared to classical (2D) X-rays.
Retroalveolar X-rays are also called periapical X-rays and offer a small image of 2-3 teeth. This procedure helps the dentist to see the tip of the roots of those teeth. In this way, the specialist will observe both the teeth and the surrounding bones.
This type of X-rays can be used for the anterior and posterior teeth. With their help, the dentist analyses exact details about tooth conditions or potential previous traumas. Retroalveolar X-rays can be used to determine whether an endodontic treatment is needed or to check the success of this treatment following root canal filling.
Panoramic X-rays show all upper and lower teeth, as well as the temporo-mandibular joint, bones and maxillary sinuses. They are used to locate fractures or pathological formations inside the jaw. They also provide the dentist with a case overview.
FAQs about dental radiology
Who reads the dental X-rays?
Dental X-rays are read by the dentist. Through a careful analysis, the dentist can identify hidden structures (such as impacted teeth), cavities or bone loss, conditions that cannot be observed with the naked eye. In addition, X-rays can be helpful after a treatment in order to analyse its success.
The X-rays look like photograph negatives, the dense structures being shown in white, the cavities in black, and the soft tissues with various shades of grey.
What is the proper time interval between two dental X-rays?
Retroalveolar X-rays expose the patient to a dose of 1-3 uSV, a value significantly lower than the natural daily radiation dose (5-8 uSV) to which we are exposed, 8 times lower than during an airplane trip (approximately 25 uSV) and 16 times lower than the dose generated by living in a brick or concrete building for 1 year (approximately 75 uSV). The dose involved by an exposure to digital panoramic X-rays is 4-14 uSV..
An annual dose of 100,000 uSV can cause cancer, 2,000,000 uSV vomiting, and 10,000,000 uSV is a lethal dose.
An analysis of these figures shows that 5-6 retroalveolar X-rays during a year do not involve any risk. The same applies to 3-4 panoramic X-rays a year.
Are dental X-rays dangerous?
Dental X-rays are not dangerous. Radiation is everywhere, from the sun's rays, microwaves and radio waves, to the food we eat every day. When these types of radiation are present in small quantities, they are not harmful - this includes the dental X-rays.
Moreover, in the case of digital dental X-rays, the exposure time is short, and the amount of radiation is considerably lower compared to activities such as flying or cooking on the stove. Digital dental X-rays use 80% less radiation, the exposure time being much shorter than in the case of the classic one.
How long are the dental X-rays valid?
It depends, on a case-by-case basis, but in most cases, if the X-rays are older than a year, they are no longer valid. In some cases, even X-rays older than 3 months may be obsolete.
