Orofacial pain conditions including temporomandibular joint disorder and migraine are characterized by peripheral and central sensitization of trigeminal nociceptive neurons. Although calcitonin gene-related peptide (CGRP) is implicated in the development of central sensitization, the pathway by which elevated spinal cord CGRP levels promote peripheral sensitization of primary trigeminal nociceptive neurons is not well understood. The goal of this study was to investigate the role of CGRP in promoting bidirectional signaling within the trigeminal system to mediate sensitization of primary trigeminal ganglion nociceptive neurons...

Approximately 30% of temporomandibular joint (TMJ) disorders include degenerative changes to the articular disc, with sex-specific differences in prevalence and severity. Limited tensile biomechanical properties of human TMJ discs have been reported. Stress relaxation tests were conducted on TMJ disc specimens harvested bilaterally from six males and six females (68.9±7.9 years), with step-strain increments of 5%, 10%, 15%, 20% and 30%, at 1% strain-per-second. Stress versus strain plots were constructed, and Young׳s Modulus, Instantaneous Modulus and Relaxed Modulus were determined...

INTRODUCTION: The temporomandibular joint is highly adaptive and masticatory apparatus disorders (MAD) can occur when its ability to adapt is overwhelmed. Occlusal etiologies were long pinpointed as the sole culprits. However, a consensus now exists which minimizes their involvement. It is recognized that the etiology of MAD is multifactorial, combining occlusal problems, parafunctions, postural anomalies, orofacial dyspraxia and stress. MATERIALS AND METHODS: In this article, the authors review the role of physiotherapy in managing these pathologies...

Oral appliance therapy (OAT) has become an increasingly popular nonsurgical option for the treatment of obstructive sleep disorders. Recent research supports its efficacy and high levels of compliance for patients with obstructive sleep disorders. Common side effects of OAT include temporomandibular joint-related symptoms, bite changes, and tooth movement. These side effects can be minimized by the use of exercises. The American Academy of Dental Sleep Medicine and the American Academy of Sleep Medicine have released joint clinical practice guidelines for the treatment of obstructive sleep apnea and snoring with OAT...

BACKGROUND: Internal derangement of the temporomandibular joint (TMJ) is one of the most common forms of temporomandibular disorders. The minimally invasive treatments such as arthrocentesis as well as arthroscopic lysis and lavage are often used as a first-line surgical treatment or in conjunction with nonsurgical modalities with low morbidity and high efficacy. Sodium hyaluronate (SH) has been proposed as an alternative therapeutic agent with similar therapeutic effects. OBJECTIVE: A prospective study was carried out for evaluation of efficacy of TMJ arthrocentesis with and without injection of SH in management of internal derangements...

Temporomandibular disorders (TMDs) are among the most common maxillofacial complaints and a major cause of orofacial pain. Although current treatments provide short- and long-term relief, alternative tissue engineering solutions are in great demand. Particularly, the development of strategies, providing long-term resolution of TMD to help patients regain normal function, is a high priority. An absolute prerequisite of tissue engineering is to understand normal structure and function. The current knowledge of anatomical, mechanical, and biochemical characteristics of the temporomandibular joint (TMJ) and associated tissues will be discussed, followed by a brief description of current TMD treatments...

Orofacial manifestations occur frequently in rheumatic diseases and usually represent early signs of disease or of its activity that are still neglected in clinical practice. Among the autoimmune rheumatic diseases with potential for oral manifestations, rheumatoid arthritis (RA), inflammatory myopathies (IM), systemic sclerosis (SSc), systemic lupus erythematosus (SLE), relapsing polychondritis (RP) and Sjögren's syndrome (SS) can be cited. Signs and symptoms such as oral hyposalivation, xerostomia, temporomandibular joint disorders, lesions of the oral mucosa, periodontal disease, dysphagia, and dysphonia may be the first expression of these rheumatic diseases...

INTRODUCTION: Patients with juvenile idiopathic arthritis (JIA) have a high risk of temporomandibular joint (TMJ) involvement. Lesions in the TMJ appear early in the course of this disease. Evaluating the structure of the TMJ in JIA patients using cone beam computed tomography (CBCT) provides an understanding of the typical radiologic features of morphological change in TMJs of JIA patients. This study aims to report these features as seen in CBCT and thus comparing them with the features observed in a control group within the same age group and in females and males...

The purpose of this work is to present a new, still experimental method of treating temporomandibular disorders (TMD) by injecting botulinum toxin Type A (TBX-A), using its effects not as a toxin but as a medication. The mechanism of TBX-A, indications and contraindications for its use, as well as possible side effects, are discussed. Temporomandibular disorders are of concern to approximately 70-80% of the population. The effect of botulinum toxin depends on blocking the release of acetylcholine from a presynaptic neuromuscular synapse and, in the autonomous system, blocking its release from post-ganglionic cholinergic neurons...

Here, the author presents a case of bruxism-induced otalgia in a 29-year-old female patient. The pain was sharp and penetrating in character. It was usually worse in the morning and frequently radiated to the right temporal area. She had received unsuccessful medical treatments for migraine headache. The otoendoscopic examination revealed a normal tympanic membrane. A thorough inspection of her teeth revealed excessive wear on the incisal edges, and the cause of her otalgia was identified as bruxism-related temporomandibular joint disorder...
