“…However, very few countries currently have established national DRLs in dental CBCT imaging (Table 3, see also [58] for a general discussion on optimisation and DRLs). Switzerland published their national DRLs for five dental indications [59] as did Finland for four dental or maxillofacial indications [60] and Sweden for three non-indication-based examinations in the dental region [61]. In the UK, Public Health England has suggested DRLs both for a specific adult and child CBCT protocol [62].…”

Cone beam computed tomography (CBCT) is a diverse 3D x-ray imaging technique that has gained significant popularity in dental radiology in the last two decades. CBCT overcomes the limitations of traditional twodimensional dental imaging and enables accurate depiction of multiplanar details of maxillofacial bony structures and surrounding soft tissues. In this review article, we provide an updated status on dental CBCT imaging and summarise the technical features of currently used CBCT scanner models, extending to recent developments in scanner technology, clinical aspects, and regulatory perspectives on dose optimisation, dosimetry, and diagnostic reference levels. We also consider the outlook of potential techniques along with issues that should be resolved in providing clinically more effective CBCT examinations that are optimised for the benefit of the patient.

“…Finally, due to the growing use of CBCT imaging [18][19][20], it is critical that its advantages and disadvantages are carefully evaluated, especially in the areas of radiation doses to patients and economic costs. Notably, the cost of CBCT imaging for assessment of impacted third molars is approximately four times higher [4], and the radiation dose, many times higher, than that for a panoramic radiograph [38,39].…”

“…The same phenomenon has been reported from Switzerland, yet panoramic imaging was still regarded as the reference investigation in dentistry. Nevertheless, it was found that wisdom teeth were the most common indication for CBCT [ 19 ]. Another study in the USA [ 20 ] investigated the use of CBCT in imaging of impacted teeth among other indications in oral and maxillofacial surgery and found an overall trend of using CBCT instead of panoramic imaging.…”

“…Another study in the USA [ 20 ] investigated the use of CBCT in imaging of impacted teeth among other indications in oral and maxillofacial surgery and found an overall trend of using CBCT instead of panoramic imaging. To reflect the expert opinion, that study proposed guidelines and the use of CBCT in the case of impacted teeth was considered to be “usually indicated” [ 19 ]. Accordingly, clinicians presumably use CBCT more frequently today, probably due to the higher confidence expected in decision-making, supported by a more exact assessment of three-dimensional anatomical relationships.…”

Radiographic imaging in relation to the mandibular third molar: a survey among oral surgeons in Sweden

et al. 2021

Objectives To query the experience of oral surgeons concerning referral routines and preferences for radiographic imaging modality before surgical removal of mandibular third molars and investigate factors that influence imaging modality preferences. Materials and methods Members of the Swedish Association of Oral and Maxillofacial Surgeons (n = 280) were invited to participate in a web-based digital survey concerning their experiences and use of three imaging modalities in pre-surgical assessment of mandibular third molar removal. The survey comprised multiple-choice questions and four cases depicted in images; respondents reported whether they would supplement the cases with other images and, if so, from which modality. Results The response rate was 64%. Panoramic radiographs were most commonly used in pre-surgical planning (response options: always or often), significant difference between professions (p = 0.039), and considered to facilitate treatment planning (87%), as was CBCT (82%); for 51%, CBCT reduced post-operative complications. Preferred modality for localizing the mandibular canal was fairly evenly distributed and for non-complex case, significant difference between subgroups of OMFS surgeons was found (p = 0.003) as to preference for intraoral radiographs. Conclusions A majority of respondents received a report within 2 weeks of their referral for CBCT and would read the report and view the images before surgery. Image modality preference differed depending on case complexity, with a greater perceived need for CBCT. Profession and practical experience affected choice. Clinical relevance Choice of imaging modality in mandibular third molar assessment is also important from dose delivery and social economy standpoints.

“…One of the most important aspects raised by the literature that could be important in the current pandemic is the establishment of faster, safer and optimal imaging diagnostic protocols 18 . For this purpose, imaging diagnostic centers should have adequate equipment hardware to perform faster scans, as well as to store and send images digitally to the responsible clinician, avoiding generation of printed exams.…”

Aim: To perform a scoped literature review on advantages of digital workflows in dentistry that could be widely adopted to address safety issues raised during the coronavirus (COVID-19) pandemic. Methods: Recent studies on any advantages of digital dentistry – as compared to conventional methods – that could help addressing the new safety demands for dental treatments that emerged due to the current pandemic were included. PUBMED, Embase, and Web of Knowledge databases were searched for eligible articles published in the last five years. The guidelines of PRISMA statement were followed during data extraction and evaluation. Results: The present search strategy yielded 181 publications. After application of exclusion criteria, a total of 34 studies were finally considered eligible to be discussed. Among the most important advantages of digital dentistry that contribute to safety during the current pandemic are: reduced number of clinical appointments required, shorter chairside time, less invasive surgeries and safer procedures. Conclusion: Within the limitations of this study, the findings observed herein suggest that the use of digital workflows in dentistry could lead to increased safety and reduced transmission of COVID-19 during the current pandemic.
