Tenosynovial giant cell tumor of diffuse type (TGCT-d) or pigmented villonodular synovitis (PVNS) is a locally aggressive lesion that mostly affects the joints of long bones. Chondroid tenosynovial giant cell tumor (CTGCT) or PVNS with chondroid metaplasia is a rare distinct subset of synovial tumors that has a predilection for the TMJ. We report a rare case of CTGCT in the TMJ, initially misdiagnosed as temporomandibular disorder (TMD). A 51-year-old woman was referred to the surgeon with the chief complaint of TMJ pain for 5 years and a past history of an unsuccessful TMD treatment...

Stem cells have self-renewal capacity and an ability to differentiate into particular cell types generating mature cells. Mesenchymal stem cells (MSCs) have a significant role in tissue homeostasis, which leads into tissue regeneration. MSCs are rare pluripotent cells supporting hematopoietic and mesenchymal cell lineages. MSCs are also believed to have therapeutic power over temporomandibular joint (TMJ) disorders (TMDs). The most common type of TMD is articular disc displacement, which induces progressive degenerative changes...

To investigate potential mechanisms associated with the increased prevalence of temporomandibular joint (TMJ) disorders among women, the study objective was to determine sex-dependent and region-dependent differences in fixed charge density (FCD) using an electrical conductivity method. Seventeen TMJ discs were harvested from nine males (77 ± 4 years) and eight females (86 ± 4 years). Specimens were prepared from the anterior band, posterior band, intermediate zone, medial disc and lateral disc. FCD was determined using an electrical conductivity method, assessing differences among disc regions and between sexes...

PURPOSE: The high prevalence of painful temporomandibular disorders (TMDs) in women suggests that estrogen and its receptors play a fundamental etiologic role in the development of this joint pathology through complex action mechanisms. The aim of this study was to evaluate the possible association between polymorphisms in the ESR1 (estrogen receptor-1) and ESRRB (estrogen-related receptor-β) genes and the risk of simultaneous development of TMDs and pain in other joints in the body...

An anterior open bite is a challenge to orthodontic treatment; it has a multifactorial etiology and a wide range of intervention options. Temporomandibular joint (TMJ) disorders are a risk factor for the development of malocclusions such as the anterior open bite, especially in patients who have TMJ osteoarthritis with disc displacement. Articular disc repositioning surgery is an available option for treating this pathology, and it contributes to maintaining the condyles in a more stable position. The aim of this article was to report the case of a 20-year-old woman diagnosed with anterior open bite and TMJ osteoarthritis with bilateral disc displacement...

Energy densities (ED, mJ/mm(3) ) quantify mechanical work imposed on articular cartilages during function. This cross-sectional study examined differences in temporomandibular joint (TMJ) ED during asymmetric versus symmetric jaw closing in healthy females versus males. ED component variables were tested for differences between and within sexes for two types of jaw closing. Seventeen female and 17 male subjects gave informed consent to participate. Diagnostic Criteria for Temporomandibular Disorders and images (magnetic resonance (MR), computed tomography) were used to confirm healthy TMJ status...

Temporomandibular joint disorders (TMJD) involve orofacial pain and functional limitations that may limit important daily activities such as chewing and speaking. This observational case-control study attempted to identify factors associated with TMJD development, particularly inflammation. The study participants were patients treated at Karolinska University Hospital, Stockholm, Sweden. The cases were patients who received a diagnosis of TMJD, chronic closed lock, or painful clicking and were treated surgically during the period from 2007 through 2011...

Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery...

After a thorough review of the history and presentation of a child's facial pain, a targeted head and neck examination is critical to the appropriate diagnosis of facial pain and temporomandibular joint disorders. It is critical to distinguish between the structural (trauma, degenerative disease, and tumor) and nonstructural (neurogenic, myogenic, and psychological) causes of pain, which will allow for incorporation of appropriate strategies of medical, psychological, dental, and surgical therapies.

BACKGROUND: Most bone metastases are observed in the trunk of the body. Metastasis in the mandibular condyle is rare. In many case reports, temporary common temporomandibular joint disorder-like symptoms can be a sign of relapse and metastasis. CASE PRESENTATION: We report a rare case of breast carcinoma metastatic to the left mandibular condyle in a 55-year-old Japanese woman, who visited our department for a dental check-up prior to chemotherapy. She had almost no symptoms, but radiographs suggested the existence of metastasis...

Sex hormones may contribute to the symptomatology of female-predominant temporomandibular disorders (TMDs) inflammatory pain. Pregnant women show less symptoms of TMDs than that of non-pregnant women. Whether progesterone (P4), one of the dominant sex hormones that regulates multiple biological functions, is involved in symptoms of TMDs remains to be explored. Freund's complete adjuvant were used to induce joint inflammation. We evaluated the behavior-related and histologic effects of P4 and the expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in the synovial membrane...

There is a paucity of in vivo studies that investigate the safety and efficacy of temporomandibular joint (TMJ) tissue regeneration approaches, in part due to the lack of established animal models. Review of disease models for study of the TMJ is presented herein with an attempt to identify relevant preclinical animal models for TMJ tissue engineering, with emphasis on the disc and condyle. Although degenerative joint disease models have been mainly performed on mice, rats, and rabbits, pre-clinical regeneration approaches must employ larger animal species...
