OBJECTIVE: MMP-13 performs digestion of collagen, which is a primary component of the temporomandibular joint (TMJ) articular disc. This study evaluated the expression of MMP-13 in patients with anterior disc displacement with (ADDwR) and without reduction (ADDwoR), and in the presence of TMJ osteoarthrosis. METHODS: Thirty-nine human temporomandibular joint disc samples were collected and divided in two ways: ADDwR (21 samples), ADDwoR (10 samples), and a control group (8 samples); and with osteoarthrosis (10 samples) and without osteoarthrosis (29 samples)...

The temporomandibular joint (TMJ) is a condylar synovial joint that, together with the masticatory muscles, controls mandibular movement during mastication. The rabbit is often used as a model species for studying the mechanisms of TMJ diseases, and in regenerative research. However, there are significant differences between rabbit and human TMJs that should be taken into account before using this model for experimental research. Here, we use several analytical approaches (radiography, computed tomography and magnetic resonance imaging) to enable a detailed description and analysis of the rabbit TMJ morphology...

INTRODUCTION: Hypermobility disorders of the Temporomandibular joint (TMJ) can be treated by both conservative and surgical approaches. Conservative approaches should be considered as first line treatment for such disorders. Prolotherapy with 25 % dextrose being injected into the posterior pericapsular tissues is one such treatment modality with favorable outcomes. AIM: To study the efficacy of single injection of 25 % dextrose in pericapsular tissues in the management of hypermobility joint disorders of TMJ as first line treatment...

Temporomandibular joint (TMJ) osteoarthritis (OA) is a complex disease that affects both cartilage and subchondral bone. It is accompanied by loss of extracellular matrix (ECM) and may be controlled by bone morphogenetic protein-2 (BMP-2). We analyzed the effect of BMP-2 in both cartilage and subchondral bone in a TMJ-OA animal model that is deficient in biglycan (Bgn) and fibromodulin (Fmod) (Bgn-/-Fmod-/-). Whole mandibles were dissected from 3-week-old wild-type (WT) and Bgn-/-Fmod-/- mice and incubated with and without 250 µg/mL BMP-2 for 2 days using an explant culture system...

Yong Won Lee, Yong Ho Park
Spontaneous temporomandibular joint (TMJ) herniation is the entity of protrusion of the retrodiscal contents of the TMJ into the external auditory canal (EAC) through a persistent Huschke's foramen. There have been a number of reports of spontaneous TMJ herniation, but there are no reports of bilateral symptomatic TMJ herniation. We report a case of a 70-year-old man who complained of a crunching sound in both ears during mastication. Examination showed bulging from the anterosuperior wall of the EAC on each side when the patient opened his mouth, which pushed the tympanic membrane medially...
