Objectives: Analyze parameters which enable the evaluation of the severity of joint sounds during Electrovibratography (EVG): Amplitude Peak (AP) and Frequency Peak (FP); analyze the correlation between the data of EVG with Temporomandibular Disorder (TMD) severity given by Craniomandibular Index (CMI). Methods: 79 subjects with TMD were submitted to clinical examinations of the Research Diagno...

BACKGROUND Purpose of this study was to modify the stethoscope which can auscultate the temporomandibular joint (TMJ) sounds more precisely than conventional stethoscope, and fabrication of stethoscope compatible software which analyses the auscultated sound and gives documentary evidence of that analysis in the form of graph. MATERIALS & METHODS The conventional stethoscope was modified by a...

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...
