Introduction: Temporomandibular joint (TMJ) disorders are among the most prevalent abnormalities of the jaw, which affect the masticatory system, including the muscles, TMJ, and tendons. Clinical examination alone cannot determine the cause of temporomandibular disorder (TMD). In most cases, the cause of TMD and a proper treatment plan are determined based on imaging modalities. The present stu...

Infectious arthritis of the temporomandibular joint (TMJ) is rare, and previous reports have identified malocclusion resulting from condylar deformity and displacement of the condyle as one of the clinical characteristics of the disease. Here we report the case of a 33-year-old man with chronic infectious arthritis of the TMJ without malocclusion associated with osteomyelitis of the right mandi...

Background No epidemiological studies have targeted the association between experience of orthodontic treatment and symptoms of temporomandibular joint (TMJ) in a large adult population. In this study, we investigated whether experience of orthodontic treatment is associated with symptoms of TMJ in adults. Methods We used data from the Fifth Korea National Health and Nutrition Examination Sur...

The aim of this study was to make a comparison of the compressive properties of the goat temporomandibular joint (TMJ) disc to the mandibular condylar cartilage (MCC) and to explore the transversely isotropic biphasic model. Samples taken mediolaterally from three regions of the TMJ disc and MCC were tested in unconfined compression at strain levels ranging from 10% to 50% and then assessed for...

OBJECTIVE The objective of the present study was to evaluate radiographic changes of the temporomandibular joint (TMJ) in patients with juvenile systemic lupus erythematosus (JSLE) and a control group. PATIENTS AND METHODS Panoramic radiographies of the TMJ of 26 JSLE patients and 28 healthy individuals were evaluated. Multislice computed tomography (MCT) was performed on those patients who p...

Small leucine-rich repeat proteoglycans (SLRP) are present in the extracellular matrix of the temporomandibular joint (TMJ) disc. Lumican and fibromodulin, classified as class 2 SLRPs, play important roles in TMJ assembly, proliferation and inflammation. Degenerative change in the TMJ disc gives rise to the process of internal derangement (ID). In this study, we immunohistochemically examined t...

The study was designed to examine the effect of persistent temporomandibular joint (TMJ) inflammation on neuronal activation in the descending pain modulatory system in response to noxious stimulus. Formalin was injected into the left masseter muscle or hindpaw of rats 10 days after injection of the left TMJ with saline or complete Freund's adjuvant (CFA). The results showed that 10-day persist...

Temporomandibular joint osteoarthritis (TMJ OA) is a common and heterogeneous disease that causes painful and progressive joint degeneration, which restricts daily activities, including talking and chewing. Long noncoding RNAs (lncRNAs) are an important class of genes involved in various physiological and pathological functions, including osteoarthritis (OA).The present study aimed to identify ...

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...
