The temporomandibular joint (TMJ) is one of the most complex joints in the human body. TMJ degenerative changes are studied by means of MRI morphological techniques. So far, to our best knowledge, there was no attempt to show the biochemical ultrastructure of cartilage in the TMJ in humans in-vivo. Our feasibility study show that the tracer accumulation occurs within 30 minutes and an inversion...

Temporomandibular joint (TMJ) ankylosis is a pathologic condition where the mandible is fused to the fossa by bony or fibrotic tissues. This interferes with mastication, speech, oral hygiene, and normal life activities, and can be potentially life threatening when struggling to acquire an airway in an emergency. Trauma is the most common cause of TMJ ankylosis, followed by infection. Diagnosis ...

Aim: The occurrence of different types of bacteria in the temporomandibular joint (TMJ) is considered an etiological factor in TMJ pathologies. Chlamydia trachomatis (ChT) and Mycoplasma pneumonia (MP) can be present in different joint pathologies. The aim of this study is to introducediagnostic resources for patients with temporomandibular joint disorders of infectious etiology. Method: Two ma...

background and aims. trauma is one of the major factors associated with temporomandibular joint disorders (tmd). these disorders result from macro-trauma or micro-trauma. macro-trauma might be iatrogenic; for example, from intubation procedures, third molar extraction procedures, and lengthy dental appointments. the aim of this study was to evaluate the effect of lengthy root canal therapy (mor...

AIMS The purpose of this study was to draw up a TMJ disc histopathological score that is a semi-quantitative transcription of the entire spectrum of TMJ disc degenerative diseases related to changes in disc tissue, and then validate the proposed grading, in order to contribute to a standardized histopathological diagnosis. METHODS Sections from sixty two temporomandibular joint disc specimens...

Fifty-eight temporomandibular joints (TMJs) from 40 patients with TMJ-related symptoms were examined by means of magnetic resonance scans with modified gradient echo sequences and a special double coil. This technique yielded a good spatial resolution of the intra-articular soft tissues, especially the articular disc and the bone structure of the TMJ. In combination with an incremental jaw open...

The present report describes the case of a 29-year-old man referred to our service for TMJ pain and progressive reduction of the mouth opening. Differential diagnostics included rheumatologic diseases, monoarthritis and intraarticular lumps. In this line, a face CT scan and a MRI of TMJ were carried out in order to ensure a proper diagnosis. These tests showed a solid lesion into the joint cavi...

The three-dimensional (3D) temporomandibular joint (TMJ) model derives from a study of the cranium by 3D virtual reality and mandibular function animation. The starting point of the project is high-fidelity digital acquisition of a human dry skull. The cooperation between the maxillofacial surgeon and the cartoonist enables the reconstruction of the fibroconnective components of the TMJ that ar...

A review of the extensive work by dentists Fonder and Smith to resolve temporomandibular joint (TMJ) syndrome shows awareness of the unity of the body and the effect of TMJ dysfunction on all body systems. However, the role of the craniosacral mechanism has not been appreciated sufficiently. Results of a retrospective study of 130 TMJ patients evaluated for craniosacral dysfunction over a 9-yea...

The TMJ, a structurally and functionally complex unit, is enclosed in an articular capsule, which extends from the articular eminence and mandibular fossa superiorly to the neck of the mandibular condyle inferiorly. The condyle is covered and protected by the TMJ disc as the disc slides between the mandibular fossa and articular eminence with joint movement. The presence of the TMJ disc reduces...
