“…could be because their sample consisted of orthodontic patients who are usually young, as studies have shown that the severity of TMJ osseous changes increases with increasing age 20, 21. One reason for the relatively higher rate of TMJ degenerative changes in our study could be that the sample was female, and several studies have shown that the TMJ degenerative changes are higher among women 20, 22…”

Objectives The aim of this study was to retrospectively evaluate the prevalence, type, and location of incidental findings by cone beam computed tomography (CBCT) scans. This study was performed to diagnose dental problems in the female population at Taibah University Dental Clinics (TUDC), KSA. Methods A series of 150 consecutive CBCT scans were identified between January 2014 and February 2016. The record was retrieved from the Carestream (CS) R4 Clinical and Practice Management Software database of TUDC. We retrospectively assessed them for incidental findings and then summarized and categorized them into five anatomical regions: nasopharyngeal airway, temporomandibular joint (TMJ), paranasal sinuses, dental findings, and alveolar bone region. We then analysed the frequency and percentage of findings in each category. Results A total of 248 incidental findings were reported in 83 of 90 scans (2.76 findings/scan). The prevalence of all incidental findings was 92.2%. The most common incidental findings were located in the paranasal sinuses and alveolar area, each representing about a quarter (27.4%) of all of the findings. Other common findings were in the TMJ (22.9%), followed by those in the nasopharyngeal airway (10.9%), dental area (10.5%), and others (0.8%). Conclusion This study confirms the high prevalence of incidental maxillofacial findings as shown by CBCT scans in a sample of female patients at TUDC. This emphasizes the need to thoroughly examine CBCT volumes for clinically significant findings inside and beyond the region of interest for the benefit of patients and the protection of practitioners.

“…Therefore, the above nine morphologic parameters were used to investigate the TMJ morphology in this study. The 2D CBCT measuring method has been validated in the related studies [18, 19, 22–24]. The 3D measuring method also has been used to evaluate the condylar morphology [15, 17, 25].…”

The differences of temporomandibular joint (TMJ) morphologic parameters by using two-dimensional (2D) and three-dimensional (3D) measuring methods were compared. Ten asymptomatic subjects (26.75 ± 4.89 years) were randomly recruited. The 3D models of the maxilla, mandible, and teeth were reconstructed according to cone-beam computed tomography (CBCT) image data. The morphologic parameters of TMJs were measured by the 2D CBCT measuring method (group A) and the 3D reconstruction model measuring method (group B), respectively. The morphologic parameters in each group were assessed by paired samples t-test, and the statistical significance was achieved when p < 0.05. The horizontal condylar angle (HCA), sagittal ramus angle (SRA), medial joint space (MJS), lateral joint space (LJS), superior joint space (SJS), and anterior joint space (AJS) in group A were significantly smaller than those in group B (p < 0.05). The HCA on the left side was significantly smaller than that on the right side in group A (p < 0.05). However, all the morphologic parameters in group B were not significantly different between left and right sides. In conclusion, there were significant differences for the morphologic parameters of TMJ measured on 2D CBCT and 3D models. 3D measuring method should be used for the detection of TMJ morphology in clinical practice.

“…The degenerative changes of the condyles were classified according to previously reported definitions as follows: 16 flattening (Figure 2a); sclerosis (Figure 2b); erosion (Figure 2c); osteophytes (Figure 2d); and combination of two or more degenerative condylar changes (Figure 2e).…”

Objectives: This study aimed to analyze any relationship between the articular eminence inclination, height and shape and degenerative condylar changes using cone-beam computed tomography (CBCT). Materials and Methods:The assessments were established on CBCT images of 566 temporomandibular joints (TMJ) that were included from the archive. Age and sex were recorded for all individuals. Degenerative changes were examined on the articular surface of the condyle. The articular eminence (AE) inclination and height measurements were performed on central parasagittal slices of the TMJs. The shape of the AE was classified as box-shaped, sigmoid, flattened, and deformed. Results:The prevalence of degenerative changes in the condyle was higher in males, but no significant difference was found (p˃0.05). Mean AE inclination and height were greater in males than females (p<0.05). Reduced mean eminence inclination and height values were detected in the +50-year-old group (p<0.05). Sigmoid and box-shaped articular eminence morphologies were more common. The eminence with a deformed shape was related to two or more degenerative alterations in the condylar head. Conclusion:The eminence inclination and height are associated with the presence and types of degenerative condylar changes. There are significant relationships between sex-AE morphology and age-AE morphology.
