Magnetic resonance imaging-based joint space measurements in temporomandibular joints with disk displacements and in controls

Agreement between Research Diagnostic Criteria for Temporomandibular Disorders and Magnetic Resonance Diagnoses of Temporomandibular disc displacement in a patient population

“…As for joints which were clinically diagnosed as having a normal diskcondyle relationship, MR showed a correct disk-condyle relationship in 70% of cases (98/140), but revealed DDR in 22 joints and DDNR in 20 joints. These findings are in agreement with other studies 19,21,22 reporting a high variability of disc position in asymptomatic subjects or highly variable symptoms in abnormal subjects. These results give a kappa value of 0.61 for the diagnosis of normal disccondyle relationship.…”

Association between mandibular condylar position and clinical dysfunction index

“…Many studies have reported nonconcentric condylar position in association with internal derangement (Sanrom an et al, 1997;Rammelsberg et al, 2000;Kurita et al, 2001;Incesu et al, 2004;Gateno et al, 2004;Ikeda and Kawamura, 2013), osteoarthritic changes (Cho and Jung, 2012), and remodeling of the articular eminence and the condyle (Scapino, 1983). Many previous studies have suggested posterior condylar position in the patients with disk displacement (Sanrom an et al, 1997;Rammelsberg et al, 2000;Kurita et al, 2001;Gateno et al, 2004;Incesu et al, 2004;Ikeda and Kawamura, 2013).…”

“…Some studies have associated the posterior condylar position with the TMD (Sanrom an et al, 1997;Rammelsberg et al, 2000;Kurita et al, 2001;Incesu et al, 2004;Gateno et al, 2004;Huang and Zhang, 2012;Ikeda and Kawamura, 2013). However, other studies have failed to demonstrate a significant association between the condylar positioning and internal derangement or signs and symptoms of patients with TMD (Bonilla-Aragon et al, 1999;Okur et al, 2012).…”

The Effect of Low Level Laser with Repositioning Appliance in the Management of Temporomandibular Joint Disc Displacement with Reduction

“…Multidisciplinary treatment of patients with DDwR has been reported to eliminate DDwR symptoms. [23] Full-time use of ARAs may be associated with adverse effects such as posterior open bite, occlusal alterations, and myostatic contracture of the inferior lateral pterygoid muscle.…”

“…Measurements of anterior and posterior joint spaces were performed using the method of Rammelsberg et al [23]. The center of the condyle was determined by determining the center of a circle which was drawn to closely approximate the condyle outline using the software program.…”
