“… 5 Two other studies reported higher mean right condylar volume than left condylar volume, although the difference was not statistically significant. 16 , 23 , 24 However, the sample size in the study by Rodrigues et al was considerably lower compared to the present study and the study by Tecco et al In another study by Schmidt et al, 8 cadaveric heads showed marked mandibular condylar asymmetry. 25 No apparent reason has been stated for the volumetric asymmetry, although most researchers attribute it to preferential one-sided mastication in study patients with malocclusion.…”

“…Though the volumetric difference between the male and female patients in our study was similar to the Italian, Spanish, Turkish, Korean, and Malaysian populations, the volumetric asymmetry between the right and left condyles was not reported in these studies. 5 , 10 , 24 , 28 , 29 In our study, there was no significant difference in the volumetric asymmetry between male and female participants. Another similarity between the results of these studies and our study was the larger volume of the right condyle compared to the left.…”

“…U-HRCT could reach a definitive diagnosis because of the more detailed radiographic findings of TMJ. Notably, no agreement has been reached on whether flattening of the condyle was a pathological condition [ 23 – 25 ]. Therefore, we classified flattening only as an indeterminant sign for TMD on U-HRCT.…”

Background Osseous changes of the temporomandibular joint (TMJ) are related to the progression of temporomandibular disorders (TMD), and computed tomography (CT) plays a vital role in disease evaluation. Objective The aims of this study were to evaluate the image quality and diagnostic value of ultra-high-resolution CT (U-HRCT) in TMD compared to cone-beam CT (CBCT). Methods TMD patients who underwent both CBCT and U-HRCT between November 2021 and September 2022 were retrospectively included. Image quality scores were assigned for four osseous structures (the cortical and trabecular bones of the condyle, articular eminence, and glenoid fossa) by two independent observers from Score 1 (unacceptable) to Score 5 (excellent). Diagnostic classification of TMD was categorized as follows: Class A (no evident lesion), Class B (indeterminate condition) and Class C (definitive lesion). Image quality scores and diagnostic classifications were compared between CBCT and U-HRCT. The Cohen’s Kappa test, Wilcoxon signed-rank test, Chi-square test and Fisher’s exact test were conducted for statistical analysis. Results Thirty TMD patients (median age, 30 years; interquartile range, 26–43 years; 25 females) with 60 TMJs were enrolled. Image quality scores were higher for U-HRCT than for CBCT by both observers (all Ps < 0.001). Definitive diagnoses (Class A and C) were achieved in more cases with U-HRCT than with CBCT (93.3% vs. 65.0%, Fisher’s exact value = 7.959, P = 0.012). Among the 21 cases which were ambiguously diagnosed (Class B) by CBCT, definitive diagnosis was achieved for 17 cases (81.0%) using U-HRCT. Conclusions U-HRCT can identify osseous changes in TMD, providing improved image quality and a more definitive diagnosis, which makes it a feasible diagnostic imaging method for TMD.

Objective: The aim of this study was to evaluate whether the volume of odontoid process of the second cervical vertebra on CBCT images can be used for sex estimation. Material and Methods: The volume of odontoid process on CBCT images of 138 subjects was measured. In addition, the patients were classified into five age groups. The comparisons between the groups in relation to sex and age were performed by using Mann-Whitney’s test and Kruskal-Wallis’ test, respectively. The ROC curve was used to assess the sensitivity and specificity of the volume to determine the sex. Results: No statistically significant difference was observed between age and volume. Males had significantly larger volumes than females. Values of volume equal to or greater than 1.254 mm3 have sensitivity of 68.2% and specificity of 68.1% to determine male sex. Conclusion: The volume of the odontoid process tends to be larger in males than in females and can be used as sex estimation.
