DIGITAL RADIOGRAPHY

Radiological examination is included in basic research in dentistry. Taking the photograph is essential while endodontic treatment (canal), in periodontal diseases, during surgery, as well as in the pediatric dentistry. Relatively the highest dose of radiating the X-ray generator transmitted while making the photograph is a defect in the traditional radiography. Our dentist's surgery is equipped in modern apparatuses/devices for digital radiography which reduces the harmful radiation about 85-90 % which became possible as compared with traditional X-rays. A possibility of making even to 8 photographs at using the dose of radiation equal of the dose for doing is indicating it of one photograph with applying of the traditional film the X-ray generator. After taking the photograph, the image appears at once on the computer screen and can be subjected to further digital processing.

Consecutive advantages of the digital radiography are:

- the option of enlarging or reducing the whole or the fragment of the image, thanks to what recognizing invisible minor changes in traditional photographs is possible. - the regulation of the contrast and brightness - function of pseudo 3-D - is showing pseudo-hollows in places with the lowered optical density and pseudo-highlighting in places which are strongly savoured out - function of the pseudo-colour (exchange of the grayscale for the color palette) - possibility of making linear measurements with the accuracy to 0.1 mm e.g. measuring the root channel long what precise conducting the endodontic treatment is possible - in radiology archiving of data is of a key importance, enabling permanent monitoring of the course of treatment is significant. All photographs are being stored in our dentist's surgery on safe digital carriers. So comparing photographs one by one, as well as the access to these data is becoming simple at any time, e.g. discretionary of patient.
