Does the horizontal condylar angle have a relationship with temporomandibular joint osteoarthritis and condylar position? A cone-beam computed tomography study

CONCLUSIONS: While the HCA increased in the presence of TMJ OA, no relationship was found between HCA and three different condylar positions.PMID:34355786 | DOI:10.5603/FM.a2021.0075

AbstractObjectivesDiabetes mellitus (DM) is associated with a broad range of complications, such as retinopathy, nephropathy, neuropathy, and cardiovascular disease. Therefore, predicting DM from head and neck images is a challenge for clinicians. The purpose of this study was to assess the mandibular condylar bone marrow in DM patients using computed tomography (CT) texture analysis.MethodsThis retrospective study included 16 DM and age and sex matched 16 control patients (11 men, 5 women; mean age, 56.8  ± 14.4 years; range 31–78 years). Patients with Type I DM, prior history of takin...

This study aimed to investigate chronic pain and the peripheral and central responses in monoiodoacetate (MIA)-induced TMJOA rats. First, the appropriate dose of MIA was determined based on pain behavior assessment in rats. Alterations of the condylar structure in TMJOA rats were evaluated by histological staining and micro-computed tomography (micro-CT). Second, the period of TMJOA chronic pain was further explored by assessing the numbers of glial fibrillary acidic protein (GFAP)-positive astrocytes and ionized calcium-binding adaptor molecule 1 (IBA-1)-positive microglia in the trigeminal spinal nucleus (TSN) and perfor...

Conclusion: Female patients had a higher prevalence and severity of TMJ-OA than male patients. The prevalence and severity of TMJ-OA increased with age, with peaks in the fifth and seventh decades of life. PMID: 33005582 [PubMed]

Our purpose was to measure the temporomandibular joint (TMJ) synovial fluid (SF) levels of vascular endothelial growth factor (VEGF) and fibroblast growth factor-2 (FGF-2) before and after intra-articular injection of hyaluronic acid (HA) and to investigate the possible mechanism involved in the therapeutic value of HA. We analysed the synovial fluid of 30 patients with unilateral internal derangement (ID) or osteoarthritis (OA) of the TMJ (confirmed by magnetic resonance imaging and cone-beam computed tomography) and recorded clinical signs and symptoms including maximal mouth opening, subjective joint pain, and joint noi...

Bone degradation of the condylar surface is seen in temporomandibular joint osteoarthritis (TMJ OA); however, the initial changes occur in the subchondral bone. This cross-sectional study was performed to evaluate 23 subchondral bone imaging biomarkers for TMJ OA. The sample consisted of high-resolution cone beam computed tomography scans of 84 subjects, divided into two groups: TMJ OA (45 patients with TMJ OA) and control (39 asymptomatic subjects). Six regions of each mandibular condyle scan were extracted for computation of five bone morphometric and 18 grey-level texture-based variables.

Human amniotic membrane (HAM) has recently been used as an interpositional material to prevent ankylosis or primary re-ankylosis after temporomandibular joint (TMJ) arthroplasty. Here, the authors describe an unusual case of a 32-year-old woman who presented with a noninflammatory degenerative osteoarthritis of the TMJ in which a HAM was placed following a high condylar arthroplasty and discectomy and show the clinicoradiological results. The procedure resulted in total pain relief and significant improvement in jaw movements. On the long-term follow-up computed tomography, complete remodeling of the glenoid fossa with for...

Conclusions: Osteoarthritis is an inflammatory, age-related, chronic and progressive degenerative joint disease. Magnetic resonance imaging (MRI) and cone-beam computed tomography (CBCT), together with clinical symptoms, play significant roles in TMJOA diagnosis. Current MRI techniques seem to be clinically useful for assessment of bony changes in temporomandibular joint (TMJ) disorders. Treatment of TMJOA requires a complex, interdisciplinary approach. TMJOA treatment includes the cooperation of physiotherapists, rheumatologists, gnathologists, orthodontists and quite often also maxillofacial surgeons and prosthodontists....

The objective was to compare the morphology of the TMJs in CBCT images regarding the number of the osteoarthritic changes diagnosed in the area of the condyle. (2) A total of 105 patients participated in the study; their 210 TMJs were allocated into one of three groups regarding the number of diagnosed osteoarthritic changes: 1 (none or 1 type), 2 (2 types), 3 (3 or more types). The morphology of the TMJ was examined for each TMJ in the CBCT images. Statistical analysis was performed with STATISTICA version 12.0. The statistical significance level was p = 0.05 for all the measurements included. (3) The articular surface fl...

CONCLUSION: Intra-articular injection of GH improved OA scores in rat TMJs in both cartilage and subchondral bone of the condyles without affecting condylar bone growth. These results suggest that intra-articular injection of human GH could be a suitable treatment option for TMJ-OA patients in the future. PMID: 32233176 [PubMed - in process]

RaskoAbstractOur purpose was to develop a reproducible and easy-to-use technique to establish the best place to inject the temporomandibular joint (TMJ) that ensured stable positioning of the condylar process. We implemented a 3-dimensional process to treat osteoarthritis of the TMJ with hyaluronic acid that was guided by cone-beam computed tomography (CT), and stabilised with a maxillomandibular wax bite block. Two wax rims (fabricated from previously-taken impressions) were attached togeth...
