Characterization and tissue engineering of the temporomandibular joint disc
The temporomandibular joint (TMJ), commonly known as the jaw joint, can cause a great deal of suffering for those afflicted with TMJ disorders. Everyday activities like chewing, yawning, and sometimes even talking and laughing, can be agonizing, and personal life and work life often suffer. …

Interspecies characterization and tissue engineering of the temporomandibular joint disc
Disorders of the temporomandibular joint (TMJ) are widespread, afflicting millions of people. The majority of these cases involve displacement or injury to the TMJ disc. Current treatments do not fully address severe cases of TMJ dysfunction; therefore, efforts to engineer functional tissues for …

Characterization of an in Vivo Model of Temporomandibular Joint Inflammation
Activation of trigeminal nerves is involved in temporomandibular joint (TMJ) inflamation and pain transmission. The proinflammatory molecule nitric oxide (NO) and protons are implicated in the underlying pathology of temporomandibular joint disorders. The goal of this study was to investigate gap …

Development and Characterization of a Mechanically Induced Temporomandibular Joint Disorder
Routine visits to an orthodontist or dentist for molar extractions or root canals can result in injury to the TMJ or muscles of mastication. The goal of our study was to develop a clinically relevant model of TMD caused by prolonged jaw opening since mechanical overloading of the TMJ is a known …

Multimedia Educational Resource of the Temporomandibular Joint for Dental Students
The temporomandibular joint (TMJ) is unique joint formed by the squamous portion of the temporal bone and the condyle of the mandible. The TMJ forms two synovial joints which are structurally supported by the mandibular condyle, joint capsule, an articular disc and supporting ligaments. The main …

TEMPOROMANDIBULAR JOINT DISORDERS AND NASAL SEPTUM DEVIATION IN DENTOFACIAL DEFORMITY PATIENTS
… Questionnaire (JPFQ) scores, diagnosis of temporomandibular disorders (TMD), and posterior facial asymmetry (PFA) as determined by nasal septum deviation were analyzed. In addition, the data will aid in the development of a phenomics database to allow for subsequent genotyping and gene …

Comparing Wear of the Osteoarthritic Temporomandibular Joint and Distal Interphalangeal Joint: A Cadaveric Study
… Osteoarthritis (OA) is a complex chronic joint disease involving degeneration of articular cartilage, subchondral bone, and adjacent tissues, often affecting multiple joints in an individual. This study aimed to determine whether OA severity and spatial wear patterns are concordant across …

Diagnostic imaging of the tympanic bulla and temporomandibular joint in the dog, cat and rabbit.
… skull incorporating the tympanic bulla (TB) and temporomandibular joint (TMJ) is significant clinically in the dog, cat, and more recently the rabbit. Diagnostic imaging is important in the assessment of disease of these structures but there is a relative lack of comparative anatomical …

The effect of isometric muscle energy technique and therapeutic jaw exercises on pain of the temporomandibular joint
… pain, to increase muscle length and to increase joint range of motion. Few investigations have focused on applications of MET and to date the temporomandibular joint (TMJ) has been completely overlooked. This study aimed to determine the effect of a specific MET technique and therapeutic jaw …

The effect of a specific isometric muscle energy technique on the range of opening of the temporomandibular joint
The objective od this study is to determine whether a specific muscle energy technique had an effect on the vertical range of opening of the mandible of the TMJ compared to therapeutic jaw exercises and non-intervention control group. Conclusions: Within the limitations of the study, the results …

Neural Crest Contributions to Dental Pulp Stem/Progenitor Cells and Craniofacial Structures: Alveolar Processes, Tongue and Temporomandibular Joint
… neural crest contributions to alveolar bone, temporomandibular joint, and tongue using a transgenic gene knockout mouse model.</p> <p> <strong>Method:</strong> Transgenic mice were generated using Cre/<em>lox</em> system, which produced Cre-mediated recombination resulting in ß-galactosidase …

Association of Masseter Muscle PITX2, ENPP1 and ESR1 Expression, Muscle Fiber Type, Temporomandibular Joint Disorders and Subclassifications of Craniofacial Asymmetry
… subclassifications of craniofacial asymmetry, temporomandibular disorders and fiber type differences compared between right and left masseter muscles. We developed an asymmetry classification that diagnosed four types of asymmetry with distinctive growth patterns: Group 1 – menton deviation …

Tinnitus and Auditory Changes in Patients with Temporomandibular Joint Dysfunction // Тинитус и слухови промени при пациенти с дисфункция на темпоромандибуларната става
… velo-palatal muscles, as well as changes in the temporomandibular joint (TMJ). For this reason, tinnitus is not considered a separate disease but only a symptom with many etiological factors. It is considered a manifestation of various diseases, including TMJ dysfunction. It can manifest as a …

Central Role Of CGRP And Protein Kinase A In Promoting Trigeminal Sensitization In An In Vivo Model Of Temporomandibular Joint Disorder
<p>Temporomandibular joint disorder (TMJD) pathology involves activation of primary nociceptive neurons that promote peripheral sensitization and excitation of second order neurons implicated in the development of central sensitization and hyperalgesia. Elevated levels of the neuropeptide …

Ontogeny of the temporomandibular joint and middle ear of the Virginia opossum (Didelphis virginiana) and their implications for mammalian cranial evolution
… mammalian middle ear from the primitive jaw joint is a remarkable example of vertebrate evolutionary history. We have a deep understanding of how the bones of the ear and jaw have evolved from the fossil record, however the knowledge surrounding the evolutionary origins of soft tissues of the …

Treatment Effects of the Mandibular Anterior Repositioning Appliance (MARA) and Conventional Orthodontic Mechanics on Temporomandibular Joint Morphology: A Comparison Using Cone Beam Computed Tomography
… The CBCT scans were evaluated using Dolphin3D©. Temporomandibular joint (TMJ) measurements were recorded in the sagittal, axial, and coronal axes, and lateral cephalograms were extracted to compare groups and evaluate treatment differences. A total of 98 variables were measured.</p> <p>Results: …
