“…15 The sensitivity of CBCT for assessing bone defects is dependent on the size of the defects, as demonstrated by Marques et al 16 and confirmed by Patel et al 17 in their investigations of simulated condylar lesions. Extremely small defects, that is, ,2 mm, proved to be difficult to detect, 17 although the sensitivity for detecting condylar osseous defects overall was fairly high: 72.9-87.5%. These measurements corroborated those reported by Marques et al, 16 but they substantially exceeded those reported by Hintze et al, 12 who investigated morphological changes such as condylar flattening and osteophytes.…”

“…It is thus suggested that erosion of the condylar surface may be easier to detect from CBCT images than other morphologic changes. 17 The diagnostic accuracy of erosive changes in the TMJ has been shown to be influenced by the imaging protocol in some studies 17,18 but not in others. 19,20 Dry human skulls were scanned with large view and standard view protocols by Zhang et al, 19 who found no significant difference between the examinations for the presence or absence of defects on the surface of the condyles.…”

“…18 In another study comparing CBCT scans with different voxel sizes (0.4 and 0.2 mm) for assessing simulated defects in fresh pig mandibular condyles, the sensitivity improved significantly for small (but not for large) defects with the increase of scanning resolution. 17 Approximately one out of three small defects (both diameter and depth ,2 mm) might be missed from diagnosis when using 0.4-mm voxel size CBCT scans. Using a higher scan resolution (0.2-mm voxel size), the defects, regardless of size, were detected with .80% sensitivity.…”

The present review will give an update on temporomandibular joint (TMJ) imaging using CBCT. It will focus on diagnostic accuracy and the value of CBCT compared with other imaging modalities for the evaluation of TMJs in different categories of patients; osteoarthritis (OA), juvenile OA, rheumatoid arthritis and related joint diseases, juvenile idiopathic arthritis and other intra-articular conditions. Finally, sections on other aspects of CBCT research related to the TMJ, clinical decision-making and concluding remarks are added. CBCT has emerged as a cost-and dose-effective imaging modality for the diagnostic assessment of a variety of TMJ conditions. The imaging modality has been found to be superior to conventional radiographical examinations as well as MRI in assessment of the TMJ. However, it should be emphasized that the diagnostic information obtained is limited to the morphology of the osseous joint components, cortical bone integrity and subcortical bone destruction/production. For evaluation of soft-tissue abnormalities, MRI is mandatory. There is an obvious need for research on the impact of CBCT examinations on patient outcome.

“…It is believed that cited studies , corroborated the methodology used, since they correlated CBCT with dimensional and positioning and shape changes of condyles. Despite having difficulties in detection by the CBCT of the condylar defect smaller than 2mm 29,30 , this difficulty would not be expected to occur in the present study, since the distances representing the condylar dimensions were measured, but not bone defects. t. In addition, the ICC15 was excellent, confirming the accuracy of the measurements performed.…”

Comparative dimensional tomographic study of the mandibular condyle of individuals with transverse maxillary deficiency

et al. 2017

Transverse maxillary deficiency is characterized by posterior uni or bilateral crossbite, crowded and rotated teeth, as well as high palate. Its treatment in adult individuals is surgically assisted rapid palatal expansion. The aim of this study was to verify the occurrence of dimensional alterations in the mandibular condyles of patients with TMD submitted to surgically assisted maxillary expansion. Measurements of the mandibular condyles using the DISTANCE tool in cone beam computed tomography iCat software were performed. The values obtained were submitted to statistical analysis by the paired t-test and the results showed statistically significant dimensional reduction in the axial posterior-anterior lateral (-0.74mm), axial posterior-anterior lateral left (-0.90mm) and coronal medium right (-1.24mm) dimensions. The coronal inferior (1.13mm), coronal inferior left (1.78mm) and coronal superior-inferior right (0.76mm) measurements showed statistically significant dimensional increase. The results allowed us to conclude that dimensional alterations occurred in the mandibular condyles in individuals with maxillary transversal deficiency that underwent surgically assisted rapid palatal expansion (SAPE), which can be understood by remodeling, since they are characterized by dimensional increase or reduction, depending on the location where the measurement was performed.
