Radiography has been used in dentistry for detecting hidden dental structures, cavities, malignant growth etc. A controlled burst of x-ray radiations is used to penetrate the oral structures and strikes the film or sensor. The teeth appear lighter in color whereas the infections and other changes in the tissues appear darker. The photographic film after it has been exposed to radiation has to be developed by using chemicals which is a time consuming process.
Digital imaging systems for intraoral radiography are becoming common in clinical practice. Compared has better performance in detecting oral cavities or caries in its initial stages itself. In radiology, the traditional photographic film is replaced by digital X-ray sensors. Instead of films, digital radiography uses a digital image capture device. Digital radiography provides so many advantages over conventional film that it's easy to see why practices are making the transition to digital dental X-ray systems some of which are:
X-ray image enhancement
Enhanced X-ray image quality
Fewer files cluttering office space
No chemical developers are required
Time and productivity savings
Quick image sharing
No more lost images
Easier to use than conventional radiography
Higher quality of care to the patients and less radiation.
