“…However, up to now, only a few reports have been published on the application of MRI in dentistry mainly due to the limited access of dentists to MRI and limitations of MRI arising from metal artifacts caused by dental fillings. Without being used widely, reported applications of MRI in dentistry include the assessment of extracranial tumors [18 -21], the assessment of the morphology and function of the temporomandibular joint [22 -27], the planning of dental implantation procedures [28 -32], planning and evaluating orthodontics and orthognathic surgery [33], the assessment of impacted teeth [34] and the mandibular and the trigeminal nerve channel [35 -41], caries diagnosis [42 -45], assessment of dental pulp [46,47], or for imaging of the mandible and mandibular for other purposes [48 -50]. With the introduction of faster imaging techniques that are less sensitive to dental filling material and the advent of new compounds, the application of MRI for periapical lesion diagnosis and characterization appears increasingly attractive and should be reconsidered.…”

Purpose: The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). Materials and Methods: 19 consecutive patients (average age 43???13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility study. Periapical lesions were defined as periapical radiolucencies (CBCT) or structural changes in the spongy bone signal (MRI), which were connected with the apical part of a root and with at least twice the width of the periodontal ligament space. The location and dimension of the lesions were compared between MRI and CBCT. Results: While mainly mineralized tissue components such as teeth and bone were visible with CBCT, complimentary information of the soft tissue components was assessable with MRI. The MRI images provided sufficient diagnostic detail for the assessment of the main structures of interest. Heterogeneous contrast was observed within the lesion, with often a clear enhancement close to the apical foramen and the periodontal gap.?No difference for lesion visibility was observed between MRI and CBCT. The lesion dimensions corresponded well, but were slightly but significantly overestimated with MRI. A heterogeneous lesion appearance was observed in several patients. Four patients presented with a well circumscribed hyperintense signal in the vicinity of the apical foramen. Conclusion: The MRI capability of soft tissue characterization may facilitate detailed analysis of periapical lesions. This clinical study confirms the applicability of multi-contrast MRI for the identification of periapical lesions. Key Points: ??MRI can be applied for the identification of periapical lesions without ionizing radiation exposure ??MRI might facilitate more detailed characterization of periapical lesions ??MRI might provide more accurate lesion dimensions as X-ray-based methods Citation Format: ??Geibel MA., Schreiber ES, Bracher AK et?al.

“…As with conventional CT, CBCT soft tissue images do not capture colour and the true texture of the skin and thus does not provide photorealistic images (Plooij et al, 2011). A set up describing the simultaneous capture of a 3D photorealistic skin surface of the face on the untextured skin image of the CBCT Scan has recently been described (Naudi et al, 2013) Amongst the first clinical applications of CBCT were angiography, single photon emission computerised tomography (SPECT) and image guided radiotherapy (Robb, 1982;De Vos et al, 2009).…”

Objectives:To determine the validity of 3dMD Vultus in predicting soft tissue morphology following orthognathic surgery. Methods:Thirteen patients with a skeletal discrepancy that required surgical correction limited to a Le Fort I surgical advancement osteotomy were included within the study. These patients had previously undergone a CBCT scan immediately before surgery (T1) and 6 months after surgery (T2).To permit validation, hard and soft tissues were linked for each time point and the hard tissues superimposed on the cranial vault and base. Using 3dMD Vultus virtual surgery was carried out to position the mandible and maxilla at T1 to the post-surgical position at T2. The resulting 3D soft tissue prediction mesh was then compared to the actual soft tissue mesh at T2 by segmenting both meshes at distinct anatomically areas of the face. The absolute distance between meshes for each region was then calculated using a custom developed computer program.
