Temporomandibular joint dysfunction (TMD) is a collection of clinical symptoms that involve masticatory muscles and the temporomandibular joint (TMJ). Common symptoms include limited jaw motion and joint sound/pain, along with TMJ disc displacement. TMD is frequently associated with synovitis, a chronic inflammation of the synovium. Fibroblast‑like synovial cells have been identified to produce several inflammatory mediators and may have an important role in the progression of TMJ inflammation. Degradation of the extracellular matrix molecule elastin may lead to the release of bioactive peptides...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a joint disorder that refers to bone or fibrous adhesion of the anatomic joint components and the ensuing loss of function. When it happens on children, it is always accompanied by dentofacial deformities. The objective of this study was to describe the authors' experience of bidirectional distraction osteogenesis for the treatment of mandibular deformities caused by TMJ ankylosis. METHODS: Sixteen patients with TMJ ankylosis and severe secondary mandibular deformities were treated with bidirectional distraction osteogenesis and release of joint from January 2013 to December 2015...

Bilateral coronoid process hyperplasia is a rare condition defined as an abnormal elongation of the mandibular coronoid process, formed of histologically normal bone. Coronoid process hyperplasia usually develops progressively, and the clinical symptoms are often similar to those of temporomandibular joint disorders (TMD). Therefore, it is often misdiagnosed as TMD initially. From 2013 to 2016, six patients were referred to our maxillofacial surgery unit by their dentist, to evaluate mouth opening with suspected TMJ disorder...

Osteoarthritis (OA) of temporomandibular joints (TMJ) occurs in about 40% of the patients who present TMJ disorders. Despite its prevalence, OA diagnosis and treatment remain controversial since there are no clear symptoms of the disease, especially in early stages. Quantitative tools based on 3D imaging of the TMJ condyle have the potential to help characterize TMJ OA changes. The goals of the tools proposed in this study are to ultimately develop robust imaging markers for diagnosis and assessment of treatment efficacy...

INTRODUCTION: Presently, during the surgical treatment of the patients in maxillofacial surgery, one can use various medical implants. Moreover custom made implants are being used. Replacements may be fitted to the structure and shape of the human skull owing to CAD/CAM (custom aided design/manufacture) called customized implants. This study was aimed to report for the first time clinical material from which custom implants, using two different techniques, were manufactured to reconstruct the temporomandibular joint (TMJ)...

The pain arising from temporomandibular disorders is often treated with opioids and agents that inhibit the immune response and are associated with substantial adverse effects and long-term risks. Thus, the development of new therapies that are safer and more effective is of great interest to patients and clinicians. 15-deoxy-Δ(12,14)-prostaglandin J2 (15d-PGJ2) is naturally produced in the human body and has anti-inflammatory properties. We have previously shown in a rat temporomandibular joint (TMJ) model that injection of 15d-PGJ2 into the rat TMJ can provide antinociceptive relief against a subsequent noxious challenge from formalin injection into the same TMJ...

Approaches providing the positioning of human amniotic membrane (HAM) within the intra-articular space of arthritic TMJs have never been investigated. This contrasts with the increasing amount of evidence suggesting the potential positive effects of HAM on a number of surgical conditions, even included the interpositional arthroplasty for TMJ ankylosis. Thus, the possible usefulness of HAM to restore joint functions in severely damaged TMJs could be hypothesized. Based on these premises, the clinical research question "Is human amniotic membrane positioning effective to reduce symptoms and restore jaw function in patients with severe inflammatory-degenerative disorders of the temporomandibular joint?" has been addressed by performing a systematic review of the literature...

Torus palatinus (TP), torus mandibularis (TM), and buccal exostosis are localised, benign, osseous projections, occurring in maxilla and mandible. Etiology is multifactorial and not well established. Tori and exostoses have been associated with parafunctional occlusal habits, temporomandibular joint (TMJ) disorders, migraine and consumption of fish. Concurrence of TP, TM, and exostosis in the same individual is very rare. Concurrence of TPand TM has not been reported from Pakistan. We report a case of a 22-year female patient manifesting concurrence of TP, bilateral TM, and maxillary buccal exostoses; with possible association of abnormal occlusal stresses and use of calcium and vitamin D supplements...

BACKGROUND: Temporomandibular Disorders (TMD) refer to several common clinical disorders which involve the masticatory muscles, the temporomandibular joint (TMJ) and the adjacent structures. Although neck signs and symptoms are found with higher prevalence in TMD patients compared to the overall population, whether limitation of cervical mobility is an additional positive finding in this cohort is still an open question. OBJECTIVE: To compare the physiological cervical range of motion (CROM) and the extent of rotation during cervical flexion (flexion-rotation test, FRT) in people with TMD (muscular origin) and healthy control subjects...

OBJECTIVE: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1...

BACKGROUND: Temporomandibular joint (TMJ) disorders show inflammatory components, heavily impacting on quality of life. Strontium ranelate has previously shown anti-inflammatory and antinociceptive effects on other experimental inflammatory pain models. Thus, we aim to investigate the strontium ranelate efficacy in reducing the zymosan-induced inflammatory hypernociception in the TMJ of rats by evaluating the TNF-α, IL-1β, and hemeoxygenase-1 (HO-1) involvement. METHODS: Wistar rats were treated with strontium ranelate (0...

BACKGROUND: Temporomandibular disorders (TMDs) have the highest prevalence in women of reproductive age. The role of estrogen in TMDs and especially in TMDs related pain is not fully elucidated. Voltage-gated sodium channel 1.7 (Nav1.7) plays a prominent role in pain perception and Nav1.7 in trigeminal ganglion (TG) is involved in the hyperalgesia of inflamed Temporomandibular joint (TMJ). Whether estrogen could upregulate trigeminal ganglionic Nav1.7 expression to enhance hyperalgesia of inflamed TMJ remains to be explored...

Temporomandibular disorder (TMD) is a very wide term which includes a variety of clinical issues related to the masticatory muscles, the temporomandibular joint (TMJ), and their associated structures (1) . For TMD patients the main concern is pain, and it is the most common reason for medical consultation; but pain makes also a great challenge for clinicians (2) . In fact, dysfunction of the central nervous system when processing nociceptive input has been stated as a factor involved in the onset and maintenance of pain in patients with chronic TMD (3) This article is protected by copyright...

Frequent involvement of the disc in temporomandibular joint (TMJ) disorders warrants attempts to tissue engineer TMJ disc replacements. Physiologically, a great degree of similarity is seen between humans and farm pigs (FPs), but the pig's rapid growth confers a significant challenge for in vivo experiments. Minipigs have a slower growth rate and are smaller than FPs, but minipig TMJ discs have yet to be fully characterized. The objective of this study was to determine the suitability of the minipig for TMJ studies by extensive structural and functional characterization...
