At present, there is a consensus among safety agencies about the need to try, whenever possible, to reduce the levels of radiation to which professionals and patients are exposed, based on the ALARA (as low as reasonably achievable), ALADA (as low as diagnostically acceptable) and ALADAIP (as low as diagnostically acceptable being indication-oriented and patientspecific) principles. The last decade has been marked by growth in the sale and use of portable hand-held X-ray devices in dental offices and universities. Since the use of these devices makes it difficult for the operator to maintain a distance of 2 meters between the radiation source and patient, it is necessary to clarify the radioprotection norms. Given the lack of clear, concise, and direct information on this topic, this Letter to the Editor is extremely relevant. The development of the portable hand-held dental X-ray device has led to several advantages, including a reduction in size and weight, which allows for easy transportation to any required location. This makes it an appealing option for use in a surgical center during operations, in forensic dentistry, community work, and home care. However, the use of portable hand-held X-ray devices in routine dental care is not recommended due to the secondary radiation dose that the operator may receive during radiographic examinations. Studies have been conducted to develop protocols that ensure excellent operator safety, reducing or avoiding exposure to radiation. Protective measures have proven effective in reducing the radiation dose to the operator, thereby enhancing protection against secondary radiation during radiographic exams conducted with portable hand-held dental X-ray devices. These measures include 1) operating the portable device with arms fully extended to maintain distance from the body, 2) using a backscatter shield on the cylinder, 3) employing a longer cylinder, 4) wearing protective aprons, 5) using lead gloves, and 6) utilizing a rectangular collimator. These precautions are particularly crucial when the operator is in close proximity to both the radiation source and the patient. Additionally, staff members and the public should maintain a distance of 2 meters from both the patient and the radiation source, and avoid standing in the path of the central X-ray beam. It is important to emphasize that radioprotection measures will only minimize the effective dose received by the professional if the operator holds the device during the examination. Only when portable hand-held dental X-ray devices are used on a stand and operated from a protected area (either 2 meters away or behind a barrier), similar to the usage of conventional radiographic devices, can operators be fully safeguarded against secondary radiation. Consequently, manufacturers should","PeriodicalId":51714,"journal":{"name":"Imaging Science in Dentistry","volume":"53 3","pages":"265-266"},"PeriodicalIF":1.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/eb/86/isd-53-265.PMC10548154.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41120193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
