Radiovisiography of teeth: indications and procedure

Radiovisiographic examination is a method of computer radiographic examination in dentistry. Its goal is to obtain an image of the tooth and tissues around it with minimal radiation exposure. It has proven itself well in diagnosing hidden carious processes, inflammation of the pulp or periodontium, and identifying foreign objects in the tooth canal. Thanks to him, the dentist has the opportunity to control the quality and effectiveness of the treatment. During the procedure, a detector is inserted into the oral cavity, which is aimed at the area under study: its image is displayed on the monitor.

You can undergo radiovisiography in Moscow at the dental department of CELT. Our clinic has been operating in the capital's paid medical services market for almost three decades. We have a modern radiovisiograph, which allows us to accurately and quickly make diagnoses, identifying diseases in the early stages of their development. Our surgeons, orthodontists, therapists, and orthopedists have decades of experience in scientific and practical work. They constantly improve their professional knowledge and skills and use effective and gentle treatment methods. You can find out the price of the study by going to the “Services and Prices” tab.

Radiovisiography in dentistry

Without radiovisiographic examination, diagnostics in dentistry would be impossible. This is computer radiography, which replaced the outdated film radiography. Thanks to it, you can get a clear image in just a few seconds, while the patient’s radiation exposure will be minimal - ten times less than when using a film device.

A digital visiograph is equipment that should be in any modern dental clinic, since today it is the only method that fully complies with international standards. Its operation is based on the same principle as a standard device, but the signal is sent not to the film, but to the CCD sensor (or, as it is also called, the matrix). The latter has greater light sensitivity than conventional film, so minimal exposure to radiation is sufficient to obtain a clear image.

The visiograph sensor is connected to a converter, which reads its signals, transforming them into a digital image. The latter is sent to the monitor where the doctor can see it. The digital format also has many advantages: it does not take up much space on your hard drive, where it can be stored for a long time, it can be transferred to a USB drive or sent by email.

How profitable is this?

And now the main question is why buy it. This is where elementary arithmetic comes to the rescue. The average cost of one package of film (1 package – 50 pictures) is 1250 rubles. The average daily throughput of the X-ray room is 15 patients. Taking into account the defect rate of 1/5, this is 20 shots per day. It turns out that one package of film is enough for 2.5 days. 144 packages are needed per year with a total cost of 180,000 rubles. And this does not take into account chemical reagents. With the average cost of a photo for a client being 120 rubles, the revenue will be 864,000 rubles. Thus, the net profit will be 684,000 rubles per year.

Let's now look at the visiograph. Its average price on the Russian market (with a resource of 400,000 images) is 130,000 rubles. Of course, there are obvious benefits. Add to this the simplest maintenance (you will have to clean it with soapy water or isopropyl alcohol), and a rather long service life.

Indications and contraindications for dental radiovisiography

The study can be used for targeted study of dental units, as well as for identifying hidden carious processes and inflammation of surrounding structures.

Indications

• Diagnosis of caries, inflammatory processes of pulp and periodontium;
• Monitoring their treatment (quality of endodontic treatment, in particular, filling of canals, correct placement of pins, tightness of seal to the walls of the tooth);
• Preparation for surgery to increase bone tissue to determine the degree of its atrophy and the characteristics of the process;
• Suspicions of neoplasms in the thickness of the soft tissues of the oral cavity;
• Cystic formations and granulomas at the roots of teeth;
• Determining the location of fragments of broken dental instruments in the root canal;
• Traumatic damage to a tooth (dislocation, bruise, fracture);
• Control of the implant after installation;
• Before sealing the fissures of teeth in order to ensure the absence of caries.

Contraindications

Absolute contraindications:

• The patient has serious mental disorders;
• Pathologies of a neurological nature;
• Depressive states.

Due to the minimal level of radiation, radiovisiography of the maxillofacial area can be performed on a child, provided that he can sit still for several seconds.

If indicated, the study can be performed on women during pregnancy and lactation. It is optimal to do this in the second trimester, after warning the diagnostician about pregnancy. This is necessary so that she is put on a special apron, which provides additional protection from x-rays.

Rules of service

To maintain hygiene conditions, the sensor must be placed in a special polyethylene case before being placed in the patient’s mouth.

For normal operation, the visiograph also requires cleaning using a soap solution or isopropyl alcohol. Before cleaning, you must turn off the power to the device. Since some disinfecting liquids can form explosive compounds when evaporated, in order to avoid ignition when turning on the visiograph after cleaning, some time is required to allow the vapors of these liquids to evaporate from the room.

IMPORTANT. It is extremely dangerous for the device if moisture gets inside the sensor or control unit. If liquid gets on the device board, it can cause a short circuit.

Advantages of radiovisiographic examination

This research method is considered the best option both for a dental office and for a large clinic in which several specialists work at once. Its advantages:

• Efficiency and the ability to receive an image instantly, without waiting;
• High clarity and information content of the image, in which you can see the condition of the teeth, surrounding tissues, and implants;
• Minimum number of restrictions (possibility of use for children and pregnant patients);
• Convenient digital format, the ability to print the image on paper.

Do not forget that visiography is an environmentally friendly and harmless research method. It does not require the use of film or aggressive chemicals for development. The radiation dose received during filming of the lower jaw is 2 microsieverts, the upper – 5 microsieverts. For comparison, when using a film apparatus, it is equal to 30 and 80 microsieverts, respectively.

The resulting images clearly show:

• Carious lesions, cystic formations, granulomas and inflammatory processes. They are transmitted in black;
• Fillings, inlays, pins, dentures – white areas;
• Connective and bone tissue are gray areas.

Flaws

Radiovisiography has only one disadvantage - the spatial resolution is one and a half to two times lower than that of film. Because of this, the sensor does not clearly convey the difference between structures that differ significantly in density. However, this shortcoming is compensated by the ability to correct the brightness and contrast of a digital image.

I am very grateful to Evgeniy Borisovich Antiukhin for removing my three eights. Especially considering that the lower tooth was not the simplest (it was located in an embrace with a nerve). The removal took place in 2 stages, one tooth under local anesthesia, two under general anesthesia. I had no idea that wisdom teeth could be... Read full review

How is dental radiovisiography performed?

The procedure is very simple and absolutely painless and does not require preparation. The patient is asked to take a sitting position on a chair near the device, after which a sensor is applied to the area under study and the patient is asked to gently bite the sensor with his teeth. This prevents its displacement. After this, the tube of the device is directed to a certain area of ​​the jaw. The diagnostician starts it, and X-rays begin to illuminate the tissue. The signals are captured by the sensor, then sent to the converter and (already in the form of a graphic image) to the monitor.

Difference between radiovisiography, OPTG and computed tomography

Unlike visiography, OPTG - orthopantogram (or, as it is also called, panoramic image) covers not one or three teeth, but the entire dental system. An orthopantomograph is used to obtain images. Most often, such diagnostics are prescribed to young patients in order to assess the condition of the rudiments of permanent teeth. As for computed tomography, it provides not a two-dimensional, but a three-dimensional image of the patients’ jaw system. For this reason, it is carried out before implantation and bone augmentation operations that precede it, in order to plan them in detail.
