Not a single branch of modern medicine can do without an X-ray apparatus . Dentistry was no exception. Sometimes it is difficult for dentists to determine the causes of a disease without a reliable examination of the oral cavity, which also includes an x-ray.
Several years ago, specialists received a film picture of the oral cavity. But now there are new generation dental devices - digital. A dental visiograph (x-ray) is used in the most difficult cases.
What is a visiograph?
Dental visiograph - a sensor that receives x-ray radiation and after processing sends the finished image to a computer. Using a visiograph allows you to minimize the processing time and print the image on film. Sensors provide more accurate information.
In addition, the visiograph is not as harmful to health as a regular x-ray. It's all about the radiation dose, which is significantly reduced.
Now it’s quite simple to find and buy a dental visiograph. What is it, we told above. More common wired devices that are connected to a computer. But wireless models are more popular among dentists because of affordability and convenience.
The advantages of the visiograph over x-ray
Visiography is the process of creating and saving an x-ray using a computer. A dental visiograph works in much the same way as a regular X-ray, with one distinctive feature - the pictures are displayed on a computer screen, and not on film. Thanks to the hypersensitive electrode, the finished image appears in the program, which allows you to find the cause of a disease that is difficult to recognize when viewed.
In dental clinics, radiovisiographs are more often used, which have a number of advantages over x-rays, or rather:
- instant diagnostic result;
- simple operation;
- low radiation (5% of conventional x-ray).
Specialists in the field of medicine approve of the use of digital technology, as the results of examinations can be stored for several years, which greatly facilitates the further analysis of medical records. The dentist can at any time pick up a document from the archive.
More accurate sighting images are not given by an x-ray, but by a dental visiograph. Photos in this case are not needed, as specialists can view the image on a computer screen.
Instrument Selection Issues
When choosing a device, you need to pay close attention to the method of obtaining a finished picture. Several years ago, experts claimed that a dental visiograph with an SSD sensor gives more accurate information due to the lack of a “blind zone”. But it is proved that this image is not accurate when compared with C-MOS sensors that produce high-quality images.
In addition, an important nuance is the resolution of the image, because the standard usually does not exceed 14 pl / mm. Often, a theoretical, that is, approximate, resolution is presented in the description of the device, so it is important to clarify this information. The compatibility of the computer and the x-ray machine with the visiograph is also important.
It is desirable that the operating mode of the x-ray apparatus coincided with the sensor, and the computer was synchronized with the device for instant data transfer.
