“…The view of the eminence in the central slice is the steepest part of the eminence. For true measurement of eminence inclination, it is the best view of eminence inclination [9, 15] and, in the present study, the central sagittal slice of the condylar process was used for measurements.…”

Aim. The aim of the present study was to examine the relationship between articular eminence inclination, height, and thickness of the roof of the glenoid fossa (RGF) according to age and gender and to assess condyle morphology including incidental findings of osseous characteristics associated with osteoarthritis (OA) of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT). Materials and Methods. CBCT images of 105 patients were evaluated retrospectively. For articular eminence inclination and height, axial views on which the condylar processes were seen with their widest mediolateral extent being used as a reference view for secondary reconstruction. Condyle morphology was categorized both in the sagittal and coronal plane. Results. The mean values of eminence inclination and height of males were higher than those of females (P < 0.05). There were significant differences in the RGF thickness in relation to sagittal condyle morphology. Among the group of OA, the mean value of the RGF thickness for “OA-osteophyte” group was the highest (1.59 mm), whereas the lowest RGF values were seen in the “OA-flattening.” Conclusion. The sagittal osteoarthritic changes may have an effect on RGF thickness by mechanical stimulation and changed stress distribution. Gender has a significant effect on eminence height (Eh) and inclination.

“…Nevertheless, an estimate is possible. Numerous studies have confirmed that the inclination of the condylar path and steepness of the eminences increase during growth [4,14,16,17,21,31]. Depending on the imaging method, such increases were from 6°-10° in children between 6 and 11 years of age.…”

“…Dass die Kondylenbahnneigung und die Steilheit der Eminentia mit dem Wachstum der Kinder zunehmen, ist durch zahlreiche Arbeiten bestätigt worden [4,14,16,17,21,31]. Bei den untersuchten Kindern im Alter von 6 bis 11 Jahren gab es Zunahmen von 6° bis 10°, je nach Methode, und nochmals Zunahmen von bis zu 14° bis zum Erwachsenenalter von 30 Jahren.…”

“…Ichikawa et al [36] studied morphological changes in the internal structure of the temporal bone (articular eminence) during growth, comparing cancellous bone from deciduous and early mixed dentitions. In this case, FD did not show any significant variation whilst other parameters used to quantify trabecular structure did change in a significant way (for example bone volume fraction, trabecular thickness, trabecular number, structure model index and trabecular bone pattern factor).…”
