Abdominal X-ray is used to assess structures in the abdomen, including stomach, spleen and intestines. KUB (kidneys, ureters, bladder) X-ray depicts the structures in the bladder and kidney. X-rays are also used to detect pathology, such as abdominal masses and fluid buildup, certain types of gallstones, kidney stones, injury to the abdominal tissue, bowel (or intestinal) obstruction, gastrointestinal perforations (from the resultant free air) and ascites (accumulation of fluid in the peritoneal cavity) free fluid. Dentists use dental radiography for the diagnoses of common oral problems, such as cavities, bone-loss, hidden dental structures and benign and malignant masses.

Digital full-mouth radiographs were taken using a dental radiography machine (CareStream Dental LLC, Atlanta, GA, USA). The radiographs were viewed on a calibrated computer screen (Samsung SyncMaster digital TV monitor, Seoul, Korea) using a software program (Image Tool 3.0 Program; Department of Dental Diagnostic Science, University of Texas Health Science Centre, San Antonio, TX, USA). ABL was defined as the vertical distance from 2 mm below the cementoenamel junction (CEJ) to the most crestal part of marginal bone. ABL was presented as the average of the sum of the mean mesial and distal ABL [13]. All radiographic examinations were performed by a trained and calibrated investigator (ZA) (kappa = 0.89). Third molars and teeth surfaces on which, the CEJ and/or the crestal bone were not clearly visible due to of technical reasons (such as dental restorations, interproximal caries, overlapping of teeth, and/or poor radiographic quality) were not assessed.

Cone-beam computed tomography (CBCT) is a newer radiological technique used in dental and maxillofacial radiology giving high diagnostic quality [1–3]. It is based on volumetric tomography and yields images in three dimensions: in the axial, sagittal and coronal planes. However, the technique delivers a relatively high radiation dose to the patients compared to traditional dental radiographic techniques but less than medical tomography, CT. The European Commission has established guidelines and regulations [4] for CBCT use in European Union (EU) member countries. Studies have evaluated various CBCT examinations to verify the need for this technique [5–7]. Studies have also investigated CBCT units from various manufacturers to measure radiation doses to patients. It was found that, due to the numerous technical settings, such as field of view (FOV), tube voltage (kV), and tube current (mA), the delivered radiation dose can vary greatly between units [8–10]. The advantage of CBCT compared with conventional dental radiography, however, is a greater amount of information, which is expected to allow more accurate radiographic evaluation.
A comprehensive review of the literature on the biological effects from dental X-ray exposures

Medical imaging procedures are essential for diagnosing disease, identifying injuries, and managing patient conditions. Dental radiography is among these procedures and is an effective means for imaging dental and maxillofacial structures to identify dental decay, infections in the bones, root pathologies and many other dental issues.
