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...

Myotonic muscle dystrophy is a systemic disease with early engagement of the facial muscles. Our aim was to study dysfunction of the temporomandibular system in patients with 'classic' dystrophia myotonica (DM1) and compare it with TMD patients and healthy controls. The study included 27 referred patients with DM1, 18 women and 9 men, aged 30-62 years, and two matched control groups: patients with temporomandibular disorders symptoms (TMD) and healthy controls, both groups were consecutive patients. The patients answered questions regarding facial pain, jaw function and dysfunction...

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...

It is estimated that 2% to 4% of the US population will seek treatment for temporomandibular joint (TMJ) symptoms, typically occurring with anterior disc displacement. The temporomandibular retrodiscal tissue (RDT) has been postulated to restrict pathologic disc displacement. To elucidate RDT function, understanding regional RDT biomechanics and ultrastructure is required. No prior biomechanical analysis has determined regional variations in RDT properties or associated biomechanical outcomes with regional variations in collagen and elastin organization...

Temporomandibular disorders (TMDs) are the most frequent non-dental orofacial pain disorders and may be associated with rheumatoid arthritis (RA), resulting in oropharyngeal dysphagia (OD). However, clinicians' understanding of involvement with OD caused by RA-related TMDs is limited and the methodological quality of research in this field has been criticised. Therefore, the aim of this study was to systematically review the prevalence of oral preparatory and oral stage signs and symptoms of OD in adults presenting with TMDs associated with RA...

Giant cell tumor (GCT) of the craniofacial bones has been reported but they are not common. This tumor occurs more often in women than in men and predominantly affects patients around the third to fifth decade of life. GCTs are generally benign but can be locally aggressive as well. We report a case of GCT involving the temporomandibular joint (TMJ), which was initially thought to be temporomandibular disorder (TMD). A 22-year-old female presented with swelling and pain over the right temporal region for 18 months associated with jaw locking and clicking sounds...

INTRODUCTION: Hypermobility disorders of the Temporomandibular joint (TMJ) can be treated by both conservative and surgical approaches. Conservative approaches should be considered as first line treatment for such disorders. Prolotherapy with 25 % dextrose being injected into the posterior pericapsular tissues is one such treatment modality with favorable outcomes. AIM: To study the efficacy of single injection of 25 % dextrose in pericapsular tissues in the management of hypermobility joint disorders of TMJ as first line treatment...

This article describes the case history of a 59-year-old female patient who sought advice for temporomandibular joint (TMJ) pain and sounds but who was actually diagnosed with a primary lung cancer with metastasis to the TMJ. The patient had a history of TMJ pain and deflection in jaw movement that progressively worsened over a few months and did not improve with the usual standard of care treatment provided by an orofacial pain practitioner. Magnetic resonance and computed tomography (CT) prescribed at a tertiary clinic showed an osteolytic bone mass within the right TMJ condyle...
