Temporomandibular joint disorders (TMJDs) are a complex group of disorders that comprise dysfunctions of the temporomandibular joint (TMJ). In this study, we analyzed the objective and subjective findings of the TMJD patients by using Helkimo anamnesis (Ai) and clinical dysfunction (Di) indices, and tried to document a relation between these findings and magnetic resonance imaging (MRI) results.Ninety-eight patients who were admitted to our clinic were included in the study. The clinical evaluation was performed by using Ai, an 8-question-survey based on the objective symptoms of patients; Di, concluded as the score of 5 objective measurements of physical examination...

Disorders affecting the temporomandibular joint (TMJ) are a long-standing health concern. TMJ disorders (TMJD) are often associated with an internal disc derangement accompanied by a suite of symptoms including joint noises, jaw dysfunction, and severe pain. The severity of patient symptoms and their reoccurrence can be alleviated to some extent with conservative therapy; however, refractory cases often require surgery that has shown only limited success. Bioengineered scaffolds with cell supportive surfaces an d nanoarchitectures that mimic TMJ tissue structure may offer an alternative treatment modality...

The role of masticatory muscle activation on pain in temporomandibular muscle and joint disorders (TMJD) is controversial. This single-group, prospective panel study examined the relationships among masticatory muscle tension, emotional distress, and TMJD pain in a sample of 7,023 observations obtained from 171 individuals using longitudinal multilevel modeling. Three main hypotheses were tested. The first posited that emotional distress and muscle tension directly influenced pain (hypothesis 1a: Distress → TMJD Pain; hypothesis 1b: Muscle Tension → TMJD Pain)...

Disorders of the temporomandibular joint (TMJ) complex affect 6-12% of the population; the joint's disc is usually involved. Tissue engineering and regenerative medicine may constitute a promising therapeutic approach, with resident stromal progenitor cells a key factor in the process. We hypothesized that the TMJ disc (TMJD) contains multipotent stromal progenitors that may play an important role in regeneration of the disc. TMJD cells were cultured and evaluated for growth kinetics and colony-forming units (CFUs)...

Introduction An earache (otalgia or ear pain) is pain in one or both ears that may last a short or long time. Earache is prevalent in the population with temporomandibular joint disorders (TMJDs), but there is a dearth of epidemiologic studies regarding the association between TMJD and ear pain and ear fullness in older people. Objective To assess the presence of earache and ear fullness in elderly patients with TMJD. Methods A cross-sectional study was conducted in independently living, elderly individuals...

Patients with temporomandibular muscle and joint disorder (TMJD) increasingly seek and receive treatment for their pain with botulinum toxin (BoNTA; botulinum toxin A). Used intramuscularly in therapeutic doses, it produces localised paresis. Such paresis creates risk of reduced bone mineral density, or 'disuse osteopenia'. Animal studies have frequently used BoNTA as a model of paralysis to induce bone changes within short periods. Osteopenic effects can be enduring in animals but have yet to be studied in humans...

Temporomandibular joint disorder (TMJD) is known for its mastication-associated pain. TMJD is medically relevant because of its prevalence, severity, chronicity, the therapy-refractoriness of its pain, and its largely elusive pathogenesis. Against this background, we sought to investigate the pathogenetic contributions of the calcium-permeable TRPV4 ion channel, robustly expressed in the trigeminal ganglion sensory neurons, to TMJ inflammation and pain behavior. We demonstrate here that TRPV4 is critical for TMJ-inflammation-evoked pain behavior in mice and that trigeminal ganglion pronociceptive changes are TRPV4-dependent...

Estrogen status and psychological stress contribute to the expression of several chronic pain conditions including temporomandibular muscle and joint disorders (TMJD). Sensory neurons that supply the temporomandibular joint (TMJ) region terminate in laminae I and V of the spinal trigeminal nucleus (Vc/C1-2 region); however, little is known about lamina-specificity and environmental influences on the encoding properties of TMJ brainstem neurons. To test the hypothesis that Vc/C1-2 neurons integrate both interoceptive and exteroceptive signals relevant for TMJ nociception, we recorded TMJ-evoked activity in superficial and deep laminae of ovariectomized rats under high and low estradiol (E2) and stress conditions...

Etiopathogenesis and clinical management of TMJD integrates a number of medical disciplines. In particular, dentistry, oral - facial surgery, neurology, rheumatology and so on. Nowadays there is no unified strategy for the management of this disease. Most cases of temporomandibular disorder (TMD) respond to simple treatment and the prognosis is good. Symptoms usually remit with simple care. In cases of secondary involvement of temporomandibular joint (TMJ), the prognosis depends on the primary disease. A comprehensive, chronological history and physical and examination of the patient, including dental history and examination, is essential to diagnose the specific condition to decide further investigations, if any, and to provide specific treatment...

BACKGROUND: Psychological stress is considered a possible pathogenic factor for temporomandibular joint disorders (TMJD), but few reports have supplied direct evidence. This study was designed to observe the effects of psychological stress on the masticatory muscles and condylar processes in rats to directly investigate the role of psychological stress in TMJD morbidity. MATERIALS AND METHODS: A well-established rat communication box model was used to compare the myoelectric profiles of temporal and masseter muscles and condylar microstructure among rats in a control group, a psychological stress group (PS group), and a diazepam (anxiolytic agent) injection group (PS + DI group)...
