Since Galileo Galilei first observed the lunar craters, Saturn and Jupiter satellites in the 16th century, there have been significant improvements in the imaging techniques with the contribution of many scientists. Today in dentistry, panoramic and periapical imaging provides comprehensive and detailed images of teeth and jaws. With the help of these required radiographic images before treatment, the problem is identified and treatment is planned in accordance with the diagnosis. Radiological imaging is an indispensable technological application that increases the success and quality of treatment in dentistry. Panoramic imaging provides the dentist with detailed information about the jaw and all teeth, while periapical imaging is an important application that provides only the image of the tooth or the region that the doctor wants to examine, and it supports the correct diagnosis and treatment plan.
