SADMFR Guidelines for the Use of Cone-Beam Computed Tomography/Digital Volume Tomography.

SADMFR Guidelines for the Use of Cone-Beam Computed Tomography/Digital Volume Tomography. Swiss Dent J. 2015;125(9):945-53 Authors: Dula K, Benic GI, Bornstein M, Dagassan-Berndt D, Filippi A, Hicklin S, Kissling-Jeger F, Luebbers HT, Sculean A, Sequeira-Byron P, Walter C, Zehnder M Abstract In 2011, the first consensus conference on guidelines for the use of cone-beam computed tomography (CBCT) was convened by the Swiss Society of Dentomaxillofacial Radiology (SGDMFR). This conference covered topics of oral and maxillofacial surgery, temporomandibular joint dysfunctions and disorders, and orthodontics. In 2014, a second consensus conference was convened on guidelines for the use of CBCT in endodontics, periodontology, reconstructive dentistry and pediatric dentistry. The guidelines are intended for all dentists in order to facilitate the decision as to when the use of CBCT is justified. As a rule, the use of CBCT is considered restrictive, since radiation protection reasons do not allow its routine use. CBCT should therefore be reserved for complex cases where its application can be expected to provide further information that is relevant to the choice of therapy. In periodontology, sufficient information is usually available from clinical examination and periapical radiographs; in endodontics alternative methods can often be used instead of CBCT; and for implant patients undergoing reconstructive dentistry, CT is of interest for the workflow from implan...

AbstractA case of tophaceous pseudogout (i.e., calcium pyrophosphate dihydrate crystal deposition disease) in the temporomandibular joint (TMJ) extending into the cranium is reported. A 59-year-old woman was referred to hospital with swelling and pain in the left cheek, and with trismus. Computed tomography imaging revealed a large, granular, calcified mass surrounding the left condylar head, partly destroying the cortex of the condylar head, and extending into the cranium by destroying the glenoid fossa. Magnetic resonance imaging revealed that the soft-tissue mass was of low-signal intensity on T1- and T2-weighted images...

DiscussionRadiographically, 2-D imaging is adequate to establish an initial radiographic diagnosis. However, more advanced modalities (computed tomography/magnetic resonance imaging [CT/MRI) are indicated to better evaluate the orientation of the tumor and assist in the surgical management. The 3-D imaging of the 3 cases presented here emphasize this point. Positron emission tomography/fluorodeoxyglucose (PET/FDG) imaging has also been recommended for specific cases. MRI may overestimate tumor aggressiveness secondary to the influence of bone marrow and soft tissue edema. The recognition of an osteochondroma is significant...

This article presents two patients with radiographic diagnosis of vertebral artery disease. In case 1, the large field of view CBCT volume was obtained for evaluation of the temporomandibular joints. A curvilinear high-density structure was seen within the left transverse foramen of C3. Based on the density, location, and shape, a radiographic diagnosis of calcified atheromatous plaque was made. The patient was referred to her physician for management. In case 2, irregularly shaped, small, high-density structures were noted on the CBCT examination close to the left carotid bifurcation at the level of C3–C4. It was al...

This study was approved by the Animal Experimental Ethics Committee of Southern Medical University, Guangzhou, China (2014-024). All experiments were performed under protocols to meet the requirements of the Association for Assessment and Accreditation of Laboratory Animal Care International and the Experimental Animal Center of Southern Medical University. Male cynomolgus monkeys (Macaca fascicularis) were used, preliminary power analysis being performed to get the proper sample size for three groups (G∗Power 3.1, Heinrich-Heine-Universität Düsseldorf, Germany; alpha = 0.05, power = 0.95; total N = 20 hem...

Conclusion(s)MRI and arthroscopic technique could be the first choice in the diagnosis and treatment of SC. Most cases were in stage 3 of the disease at the first visit. Low recurrence rate may be attributed to the improvement of intra-articular environment after surgery. Larger sample sizes are needed for further study.

ConclusionsThe 4 hallmark radiographic findings for an aberrant ICA are an enlarged inferior tympanic canaliculus (ITC), an enhancing hypotympanic mass, an absent vertical segment of the ICA, and dehiscence of the cortex covering the tympanic portion of the ICA.4 Because of the lack of soft tissue/vascular contrast on a CBCT image, only an enlarged ITC and dehiscence of the cortex were seen in this study. Aberrant ICAs are known to cause tinnitus, which can mimic symptoms of a temporomandibular disorder (TMD).5 Because the patient was lost to follow-up, these findings could not be correlated clinically. However, it is impo...

CONCLUSIONS: There was no conclusive evidence found regarding correlation between TMJ clinical signs and radiological features of osseous destruction in patients with JIA - only weak correlation between pain and condyle surface flattening was observed. The number of clinical TMJ signs does not correlate with number of radiological features. For the clinical decision both clinical examination and CBCT would be useful in the early detection of osseous destruction of the TMJ in JIA patients. PMID: 30531162 [PubMed - in process]
