Abstract Dental radiology has emerged as a crucial tool in modern dentistry. Radiographs play an essential role in periodontal assessments for individuals exhibiting clinical signs of periodontal destruction and provide vital information relevant to periodontal decision-making. Traditionally, periodontal diagnosis has heavily relied on intraoral radiographs, extraoral panoramic radiographs, and cone-beam computed tomography (CBCT). However, an integral part of radiology is exposure of patients and, potentially, clinical staff to X-rays with considerable adverse effects. For this reason it is prerequisite to measure the dose to the patients in the diagnostic radiology precisely. In addition, the radiation dose to the patients should be as low as reasonably achievable, a principle known as ALARA. The number of diagnostic examinations should also be taken into consideration because the risk is directly proportional to the frequency of X-ray exposure. There is a lack of comprehensive research on radiation exposure related to periodontal diagnosis since the 2017 classification, which incorporated radiographs into diagnostic and treatment planning. This review paper aims to address this gap by examining radiation doses associated with various diagnostic methods and exploring strategies for radiation protection.
