Load during mastication is an important factor for the development and maintenance of mechano- receptor properties. The purpose of this study was to examine property changes in the rat TMJ mechano-receptors under conditions of liquid diet feeding and low articular load during the growth period. The hypothesis was that alterations in mastication of liquid diet might increase TMJ mechano-receptor...

In an attempt to gain a better understanding of temporomandibular joint (TMJ) sounds, we recorded joint sounds from 14 non-orthodontically treated dental students, analyzed the acoustic characteristics of the TMJ sounds, and correlated the sound characteristics with axiographic features, morphologic observations of X-ray images and clinical history. The group with a low peak frequency (< 500 Hz...

OBJECTIVE To detail the progress of a patient with TMJ dysfunction and headaches due to swimming, who underwent a conservative treatment plan featuring soft tissue therapy, spinal manipulative therapy, and rehabilitation. CLINICAL FEATURES The most important features were initial bilateral temporal headaches and persistent left sided TMJ pain brought about by bilateral breathing while swimmin...

Rheumatoid arthritis (RA) is a systemic inflammatory, slowly progressive disease that results in cartilage and bone destruction. Temporomandibular joint (TMJ) involvement is not uncommon in RA, and it is present in about more than 50% of patients; however, TMJ is usually among the last joints to be involved and is associated with many varied clinical signs and symptoms. Hence, RA of TMJ present...

Currently, there are basically two approaches to classification, one based on structural and one on positional changes occurring within the joint. Despite the increase in knowledge of pathologic changes occurring within the temporomandibular joint (TMJ), the disc still seems to be a central issue in nomenclature and classifications of TMJ disorders. Basic pathologies of the TMJ involve inflamma...

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...
