A correctly taken image provides a good overview of teeth and jaw, whereas radiopaque foreign materials, e.\u200ag. metal, can obscure relevant findings.<\/jats:p>\n                  <jats:p>Methods\u2002A literature review on unexpected metallic foreign bodies in OPG was performed to determine the spectrum of metallic foreign bodies that may cause radiopaque areas on panoramic radiographs in routine clinical use.<\/jats:p>\n                  <jats:p>Results and Conclusion\u2002A total of 37 different unexpected metallic foreign bodies were found. They can be categorized as jewelry, clothing, personal protective equipment, medical devices, iatrogenic foreign bodies, and rare incidental findings. Radiopaque foreign materials in the OPG are often relatively easy to recognize as artifacts because of their location, and they are avoidable in most cases. If unclear, a three-dimensional radiograph was helpful for determining the location. Radiopaque areas caused by foreign bodies can lead to misinterpretation or partial or complete non-evaluability and should therefore be avoided.<\/jats:p>\n                  <jats:p>Key Points:\u2002<\/jats:p>\n                  <jats:p>Citation Format<\/jats:p>","DOI":"10.1055\/a-2064-9407","type":"journal-article","created":{"date-parts":[[2023,5,10]],"date-time":"2023-05-10T04:37:46Z","timestamp":1683693466000},"page":"809-818","source":"Crossref","is-referenced-by-count":2,"title":["Unexpected metallic foreign bodies on panoramic scans \u2013 a narrative review"],"prefix":"10.1055","volume":"195","author":[{"given":"Hans Ulrich","family":"Brauer","sequence":"additional","affiliation":[{"name":"Policlinic, Dental Academy for Continuing Professional Development, Karlsruhe, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Bartols","sequence":"additional","affiliation":[{"name":"Policlinic, Dental Academy for Continuing Professional Development, Karlsruhe, Germany"},{"name":"Clinic for Conservative Dentistry and Periodontology, Christian-Albrechts-University Kiel, Kiel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Hellmann","sequence":"additional","affiliation":[{"name":"Policlinic, Dental Academy for Continuing Professional Development, Karlsruhe, Germany"},{"name":"Department of Prosthetic Dentistry, Julius Maximilians University W\u00fcrzburg, W\u00fcrzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"Boldt","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry, Julius Maximilians University W\u00fcrzburg, W\u00fcrzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2023,5,9]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"1209","DOI":"10.1007\/s00784-017-2204-1","article-title":"High-resolution MR imaging for dental impressions: a feasibility study","volume":"22","author":"J Boldt","year":"2018","journal-title":"Clin Oral Investig"},{"issue":"11","key":"ref2","doi-asserted-by":"crossref","first-page":"720","DOI":"10.1097\/RLI.0000000000000890","article-title":"High-resolution single tooth MRI with an inductively coupled intraoral coil \u2013 Can MRI compete with CBCT?","volume":"57","author":"T Hilgenfeld","year":"2022","journal-title":"Invest Radiol"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"192","DOI":"10.1055\/a-0636-4129","article-title":"Dental Imaging \u2013 A basic guide for the radiologist","volume":"191","author":"M Masthoff","year":"2019","journal-title":"Fortschr R\u00f6ntgenstr"},{"issue":"05","key":"ref4","first-page":"525","article-title":"Dosimetry of occupational radiation around panoramic x-ray apparatus","volume":"9","author":"A H Pakravan","year":"2019","journal-title":"J Biomed Phys Eng"},{"key":"ref5","volume-title":"Zahn\u00e4rztliche Radiologie","author":"A Fuhrmann","year":"2013","edition":"1.
