Purpose: Routine dental X-rays are among the most common sources of ionizing radiation exposure for healthy individuals globally, with 300 examinations/1000 individuals/year as documented by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) global survey of medical radiation usage and exposure. Furthermore, in the United States of America, an increased use of dental radiography is evident. However, with the shift from using film to digital image receptors, the dose of radiation per routine examination has decreased. Despite this, there remains public concern of dental X-rays. This continuing concern highlights the need to review the literature on biological and health effects related to exposure, from dental X-rays. Material and methods: This report presents studies investigating biological and health effects related to exposures using dental X-rays in patients and provides a critical evaluation. Relevant studies specific to dental X-rays are reviewed from 1970 and onward with the bulk data in this field resulting from epidemiological and biomonitoring studies. Results: While, most epidemiological studies suggest a possible correlation between head/neck related tumors and exposure to dental X-rays, evidence for causation is lacking. Biomonitoring studies suggest that exposure to low-level radiation such as that of dental radiography may not be a factor in inducing long-term chromosomal damage, but may result in localized cytotoxicity in the irradiated region of the mouth, with no long-term harm. Conclusions: In general, the total number of studies is low and the majority of the data has been generated from poorly designed experiments. This review will highlight shortcomings that could influence outcomes and provide a more balanced interpretation that could impact the public perception and the level of public concern on the health effects resulting from dental X-rays.

“…This results in an effective dose of E = 31 µSv. For comparison, the average effective dose of panoramic radiography is approximately 36 µSv, whereas the dose for intraoral radiography is approximately 0.8 µSv (range: 0.1–2.6 µSv) (Granlund, Thilander‐Klang, Ylhan, Lofthag‐Hansen, & Ekestubbe, ). If less conservative CBCT conversion coefficients are applied (Shin et al, ), it can even be argued that the LD‐CBCT effective dose (in this case: 2.9 µSv) is within the range of that of IR.…”

Objectives To investigate the in vitro diagnostic accuracy of low‐dose cone‐beam computed tomography (LD‐CBCT) for the detection, classification, and measurement of peri‐implant bone lesions. Material and methods Titanium dental implants with all‐ceramic single crowns (n = 24) were inserted into bovine bone. At twelve implants, four types of peri‐implant bone lesions were created. Radiographic imaging was performed using three techniques: LD‐CBCT, high‐definition CBCT (HD‐CBCT), and intraoral radiography (IR). The datasets were presented twice to four observers in a random order. Diagnostic accuracy was measured by calculating sensitivity and specificity, and analyzed using the McNemar's test at a significance level of 0.05. Absolute agreement between the defect sizes was assessed by means of intraclass correlation coefficients (ICC). Results For all three techniques, diagnostic accuracy and reliability for the detection of defects were almost perfect. The following order was found for classification of the different defect types (sensitivity/specificity): HD‐CBCT (0.96/0.99) > LD‐CBCT (0.93/0.98) > IR (0.71/0.95). No significant difference was found between the two CBCT techniques. Their performance was superior to that of IR. With regard to absolute agreement of defect size, LD‐CBCT agreement with HD‐CBCT (ICC, 95% confidence interval) was slight for defect depth (0.342, 0.181–0.625) and substantial for defect width (0.911, 0.775–0.963). Conclusion Intraoral radiography is useful for detecting peri‐implant bone lesions. LD‐CBCT provides additional information regarding the geometry of defects. The even higher diagnostic accuracy of the HD‐CBCT protocol tested needs to be carefully weighed against its radiation dose, which is 14 times higher than that of LD‐CBCT.

Objective: To know about the current state of knowledge in diagnostic radiation safety which is uppermost in mind of all the dental clinicians. Methods: A total of 301 references were reviewed using standard search engines Pubmed and Google. Twenty-two, were selected as relevant by all the authors, for our area of inquiry. The temporal status of these studies were from 2008 to 2017. Two categories of research was identified, those with anthropometric phantoms and those with real patients. Results: Initially we divided them into Phantom based studies (17) 77.27% and the patient-based studies were (5) 22.73%. There is paucity of actual patient studies due to noncooperation by patients for radiation-based study and also because of severe restriction by ethical committee to give permission for such study. Conclusion: The extensive Phantom based studies and specific patient studies of radiation measurement in diagnostic dental domain has suggested to a large extent that this is a safe mode of tool of treatment selection. The risks are very minimal and unnecessary radiography must be avoided and each radiographic session must be customized.
