Incidental dentomaxillofacial findings on cone beam computed tomography images of Iranian population

Background and aim: the present study aimed to assess the nature and prevalence of incidental findings in conebeam computed tomography (cbct) images of oral and maxillofacial patients.methods: in this cross-sectional study, 773 cbct samples were retrieved from archives of a private oral andmaxillofacial radiology center. any findings that were not related to the reason of cbct request was recorded in formsdesigned originally for this study.results: 475 patients out of 773 had at least one incidental finding. it composed about 60% of the patients. the largestfrequency of incidental findings were cases of periapical lesions. (n = 189), followed by mucous thickening of maxillarysinus (n = 170), retained root (n = 32), impaction and 3rd molar (n = 26). other incidental findings were torus (n = 25),dental anomalies (n = 13), vertical root fracture (n = 5), intra bony lesion and periapical pathosis (n = 4) and the lowestfrequency was sialoliths (n = 1).conclusion: about half of the subjects have had at least one incidental finding, so the precise review of the cbctimages seems to be necessary.
