“…18,22,23 Some researchers have reported an association between an increasing age and the prevalence of TMJ OA, 9,18 whereas others have found no such correlation. 24,25 In the present study, bony changes in the condyle were more frequently detected than changes in the articular eminence and articular fossa. The most frequent finding in this study was condylar flattening, which is mostly consistent with previous studies.…”

“…The most frequent finding in this study was condylar flattening, which is mostly consistent with previous studies. 9,18,19,24 However, this finding is incompatible with the results reported by Massilla Mani and Sivasubramanian, who found erosion as the predominant finding, 26 and by Nah, who found sclerosis to be the most common finding. 27 The discrepancy between these results may be attributed to gender and age differences, racial/ethnic disparity and the diagnostic criteria for OA.…”

“…The present results are consistent with the studies in which the mean ages of the patients were similar with regard to the absence and presence of the sclerosis of the articular fossa. 24,25 The RDC/TMD criteria suggest the evaluation of the joint space in a maximum intercuspation position of the condyle, because the joint space can change during mastication or mouth opening. 2 The narrowing of the joint space was one of the common alterations in this study, which coexisted with other signs of OA in all cases.…”

Background. Cone-beam computed tomography (CBCT) enables the radiographic examination and evaluation of osseous changes in the temporomandibular joint (TMJ).Objectives. The aim of this study was to determine the prevalence of various bony changes in TMJ in patients from a wide age range as well as to evaluate the CBCT findings of TMJ osteoarthritis (OA) and correlate them with age. Material and methods.The study included the CBCT images of 150 patients (43 males and 107 females) who were refferred to the Department of Dentomaxillofacial Radiology for the evaluation of TMJs. Each TMJ was evaluated separately for the presence of any osseous changes in the condylar head or articular fossa/eminence, and for joint space narrowing.Results. The mean age of the sample was 37.26 years (range: 10-90 years). A total of 101 (67.3%) patients presented 1 or more osseous changes. No significant differences were found between the right and left TMJs concerning the prevalence rates of osseous changes. Significant differences were found in the mean ages with regard to the absence and presence of the following findings: condylar erosion, osteophytes, loose bodies, erosion in the articular fossa, and joint space narrowing. Conclusions.Degenerative changes in TMJ may reflect an age-related bone remodeling process. Older patients may have more common findings of OA, such as condylar and articular erosion, osteophytes, loose joint bodies, and joint space narrowing.

“…Although all participants in this study were treated with OSA, most of the older people group had condylar erosion even after treatment; erosions disappeared in only 15.2% of patients. It is a higher frequency than the distribution of erosion shown in asymptomatic elderly participants in previous studies [22,23,25]. In addition, while the erosion of articular eminence was disappeared in the control group, it hardly decreased in the older people group.…”

Background and Objectives: The relatively high prevalence of temporomandibular joint (TMJ) osteoarthritis (OA) in older people increases the necessity to investigate the specific characteristics of TMJ-OA in this particular population. This study aimed to analyze the longitudinal changes in clinical and radiological characteristics of TMJ-OA in older people. Methods: We retrospectively analyzed the clinical features and cone-beam computed tomography (CBCT) images of 76 participants with TMJ-OA. Participants were classified into two groups according to age. The older people group included 33 participants over 50 years of age, and the control group included 43 participants in their 15-29 years. We analyzed the differences in clinical features and the distribution of destructive bony changes on CBCT images between groups. Results: The duration of pain was significantly shorter in the older people group (P = .046); however, the treatment duration was significantly longer in the older people group (P = .001). There was a significant difference in the distribution of destructive bony features between groups (P = .005). In the older people group, “three or more features” (36.3%) were the most common, whereas in the control group, “erosion” (44.2%) was the most common. After treatment, there was little improvement in the frequency of “erosion” in the older people group. There was a significant difference in the proportion of erosion after treatment between the groups (P = .033). Conclusion: In older people with TMJ-OA, active treatment to effectively induce condylar remodeling should be considered.

“…Flattening, sclerosis, and osteophyte not accompanied by erosion are considered undestructive changes [14,15]. Previous studies reported that these undestructive features had been observed with 10 ~ 40% frequency in asymptomatic elderly patients [22,23,25].…”
