All images were obtained using the bisecting angle technique with photostimulable phosphor (PSP) plates, without the use of a film holder, and were assessed by four observers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>One or more technical errors were identified in 783 of the 960 images (81.6%). The most common error was related to sensor positioning, both before and after the demonstration (57.3% and 55.6%, respectively). The highest proportion of errors was identified in the maxillary anterior region (26.8%), followed by the mandibular anterior region (21.6%). Errors were slightly more prevalent in the maxilla (53.6%) than in the mandible (46.4%). The frequency of technical errors before and after the demonstration was similar, with statistically significant differences noted only for crown cutoff, non\u2010parallel positioning to the occlusal plane, and shortening errors. A decrease in the total number of errors was observed in approximately two\u2010thirds of the students (61.25%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These findings highlight the need to strengthen undergraduate dental education in radiographic techniques and radiation protection. Integrating structured instruction on radiographic errors and their correction earlier in the curriculum may enhance student competence. In addition to practical demonstrations, the incorporation of simulation\u2010based training, supervised clinical practice, and structured feedback could further improve radiographic skills and reduce technical errors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jdd.70109","type":"journal-article","created":{"date-parts":[[2025,11,25]],"date-time":"2025-11-25T06:08:06Z","timestamp":1764050886000},"page":"1146-1158","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Practical Demonstration on Reducing Technical Radiographic Errors Made by Dental Students"],"prefix":"10.1002","volume":"90","author":[{"given":"Berceste","family":"Polat Akmansoy","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology Faculty of Dentistry Marmara University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tugce","family":"Gungor","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology Faculty of Dentistry Marmara University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tugba","family":"Cebeci","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology Faculty of Dentistry Marmara University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebnem","family":"Ercalik Yalcinkaya","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology Faculty of Dentistry Marmara University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7734-4755","authenticated-orcid":false,"given":"Birsay","family":"Gumru","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology Faculty of Dentistry Marmara University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,24]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.2008.0357"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016350903514426"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.4103\/1119\u20103077.164338"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.22271\/oral.2020.v6.i4a.1039"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.21726\/rsbo.v6i1.1194"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.31661\/gmj.v2i2.71"},{"key":"e_1_2_8_8_1","first-page":"1","article-title":"Quality of Working Length Radiographs Taken and Used by Dental Students During Endodontic Treatment","volume":"1","author":"Jayasinghe R.
