Abstract
Introduction:The Council Directive 2013/59 Euratom has a clear commitment for keeping medical radiation exposure as low as reasonably achievable and demands a regular review and use of diagnostic reference levels.Methods:In dental implantology, the range of effective doses for cone beam computed tomography (CBCT) shows a broad overlap with multislice computed tomography (MSCT). More recently, ultralow dose imaging with new generations of MSCT scanners may impart radiation doses equal to or lower than CBCT. Dose reductions in MSCT have been further facilitated by the introduction of iterative image reconstruction technology (IRT), which provides substantial noise reduction over the current standard of filtered backward projection (FBP).Aim:The aim of this article is to review the available literature on ultralow dose CT imaging and IRTs in dental implantology imaging and to summarize their influence on spatial and contrast resolution, image noise, tissue density measurements, and validity of linear measurements of the jaws.Conclusion:Application of ultralow dose MSCT with IRT technology in dental implantology offers the potential for very large dose reductions compared with standard dose imaging. Yet, evaluation of various diagnostic tasks related to dental implantology is still needed to confirm the results obtained with various IRTs and ultra-low doses so far.
Highlights
The Council Directive 2013/59 Euratom has a clear commitment for keeping medical radiation exposure as low as reasonably achievable and demands a regular review and use of diagnostic reference levels
All doses due to medical exposures should be kept as low as reasonably achievable consistent with obtaining the required medical information; and the amount of patient exposure should form part of the report. This National Council on radiation protection has attempted to emphasize the importance of optimization in medical imaging through modification of the ALARA As Low As Reasonably Achievable concept to ALADA, As Low As Diagnostically Achievable, which stresses that the aim of imaging should be to use the lowest possible dose which will produce diagnostic images [6]
Modern multi slice computed tomography (MSCT) has an enormous potential for dose reductions and currently allows doses less than Cone beam computed tomography (CBCT)

Diagnostic reference levels for dental implant imaging should be developed and regularly reviewed
