“…12 We also observed a predominance of female over male subjects, an observation consistent with a tendency reported in the related literature. 5,6,13,14 Osteoarthritis, on the other hand, was observed in 30% of the samples, which is in agreement with other studies stating that bone abnormalities are not always related to symptom reports by patients. 5,9 We also observed that the condylar OA characteristics were associated, predominated by the erosion/osteophyte combination.…”

The aim of the present study was to investigate the relationship between degenerative bone changes of the head of the mandible and the presence of joint effusion (JE). This study was based on sagittal magnetic resonance imaging (MRI) reports of 148 temporomandibular joints (TMJs) of 74 patients complaining of pain and/or dysfunction in the TMJ area. The mandible heads were surveyed for osteoarthritis characteristics, which were classified as osteophytosis, sclerosis or erosion. The presence of JE was checked whenever high signal intensity was observed in the articular space. The results evidenced the presence of bone changes in 30% of the sample. Osteophytes and erosions were the changes most commonly observed. JE was reported in 10% of TMJs. The results from the statistical tests revealed that bone changes in the head of the mandible are associated with the presence of JE.

“…This finding is corroborated by a study reporting a higher frequency of osteophytes and erosions combined. 5 JE was found in 10.1% of subjects, which agrees with the findings of another study reporting this same percentage in symptomatic patients. 12 The minute size of the intra-articular space and the similarity between the synovial liquid and the JE signals on MR images make it difficult to distinguish these signals.…”

“…4,5 These changes are considered radiological signs of osteoarthritis (OA), and have been observed in symptomatic TMJs. 5,6 If a strong association between the presence of JE and OA were to be established, this could be the basis for valuable additional diagnostic information. The aim of this study was thus to investigate the relationships between OA in the head of the mandible and the presence of JE, by analyzing MR images of the TMJs of symptomatic patients.…”

“…Campos et al in 2008 did a similar study observed that 91% of the cases showed changes in condyle and only 1% of the cases showed changes in articular surface. 19 He documented that degenerative changes were significantly more frequent in the condyle than in articular eminence. But in our study more changes were seen in articular surface and eminence.…”

Background: The aim of this study was to evaluate efficacy of segmental cone beam computed tomography (CBCT) in detecting bony changes in condyle and thickness of roof of glenoid fossa in temporomandibular joint (TMJ) disorders.Methods: The study group comprised of 10 temporomandibular disorders (TMD) patients of either sex between the age group of 20-60 years diagnosed as TMDs by clinical evaluation using the research diagnostic criteria was considered. After the clinical examination, radiographic investigations were carried out which included digital OPG, transcranial radiograph and CBCT scan. TMJ Evaluation included: (a) bony changes of the condyle (flattening, erosion, sclerosis, osteophytes, resorption); (b) joint space (normal, increased, reduced, bony contact between the condyle and the mandibular fossa); and (c) bony changes of mandibular fossa (normal, sclerosis, erosion, resorption). The radiographic findings were statistically analysed.Results: Significant difference between OPG, transcranial and CBCT were found for the presence of erosion (P =0.000), thickness of roof of glenoid fossa (P =0.000), deformed contour (P =0.001), joint space (P =0.011), subchondral sclerosis (P =0.011), irregularity of articular surface and eminence (P =0.000), flattening (P =0.050). Conclusions: Using CBCT as imaging technique in our study to detect osseous changes in the TMJ was proved to be effective as compared to the conventional radiographic techniques, the results achieved with CBCT was 100%.The results obtained in our study prove to be a full proof one and it seems to promise to go one step closer to detect progression and severity of the osseous changes in the condylar head and mandibular fossa in patients with TMDs.
