Gender, educational level, and reported knowledge about X-rays were not associated with correct answers (P > 0.05). Younger patients answered more accurately that ultrasound (P = 0.009) and MRI (P = 0.025) do not use X-rays, and older patients correctly associated mammography with X-rays (P < 0.001). Patients whose information source was the internet tended to incorrectly state that mammography (P = 0.007) and tomography (P = 0.063) did not use X-rays.</p><p><strong>Conclusion: </strong>Patients often fail to differentiate the imaging exams that use X-rays, despite reporting that they understand what X-rays are. Dentists should be aware of the misconceptions patients may encounter when using the internet as a source of information and provide clearer guidance about acquisition and purpose of imaging exams, with emphasis on radiation protection.</p>","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":"460-466"},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
