Dental panoramic radiography is a technique which produces single tomographic images of facial structures, which includes both the maxillary and mandibular dental arches, and their supporting structures. It displays a two-dimensional image of the teeth, from ear-to-ear, by taking images at multiple planes to prepare a composite panoramic image. Panoramic radiography is a field of tomography that allows imaging one section of a body, while blurring other sections. A dental panoramic radiograph uses a small dose of ionization radiation, and captures the image of the entire mouth structure in one image. The procedure is commonly performed by dentists and oral surgeons, in diagnosis, treatment assessment, placement of dental implants, pre & post-operative orthodontic assessment, tooth extraction, braces fitting and other diagnostic and treatment procedures. However, dental panoramic radiography technique is not recommended for detection of dental caries, periapical abcess, or in cases as a substitute for intraoral films. Dental panoramic radiography is based on the concept of rotational imaging, where a rotational center in the radiograph, is the axis around which the cassette and x-ray tube head rotate. There are three main types of rotation centers in a dental panoramic radiograph namely double center rotation, triple center rotation, and moving center rotation. Oral problems have been a great cause of concern globally, with an estimated 15-20% of world's population was suffering from severe periodontitis, in 2013, according to WHO. According to World Dental organization statistics, in 2010, around 3,054 Mn people suffered from untreated tooth decay and the global economic impact of dental diseases accounted for US$ 442 Mn. Around 83% children, and 62% adults visited dental healthcare settings in 2014, according to Centers of Disease Control.
