Objective: To measure the permeability of human temporomandibular joint (TMJ) disc and cartilage to provide basic parameter for oral biomechanics and tissue engineering, and analyze its mechanisms of pathology and load-release.
Methods: Confined compression method was used to measure the permeability (k value) of four cadavers' TMJs, which were sampled into three parts: disc, condyle and glenoid fossa with different diameters (2 mm, 3 mm and 4 mm). All 128 samples were tested with correspond diameter indenter.
Results: Larger the sample diameter was, higher the k value became. The highest k value appeared in the disc while the lowest appeared in glenoid fossa.
Conclusion: In normal condition, TMJ can suffer huge load by decreasing its permeability. Disc is weakest for the higher permeability, it's easy-damaged region is an initiated factor of TMJ disease.

Introduction: Temporomandibular joint (TMJ) septic arthritis is a rare frequently misdiagnosed condition with non-specific symptoms. We present our experience of thirteen cases of TMJ septic arthritis and perform a systematic review of the literature to collate the multiple characteristics of this condition.
Material And Method: A total of 133 cases of TMJ septic arthritis in humans across 62 studies were analyzed by searching PubMed, Cochrane Library, DOAJ and ClinicalTrials.

Introduction: The temporomandibular joint (TMJ) is one of the most intricate anatomical entities within the human body and is clinically relevant in the field of dentistry. Therefore, the present study aimed to conduct a three-dimensional (3D) volumetric comparison of the TMJ space in skeletal Class I and II patients using cone-beam computed tomography (CBCT).
Materials And Methods: This cross-sectional, retrospective study was conducted on 40 CBCT records divided into skeletal Class I and skeletal Class II patients.

The coronavirus disease 2019 (COVID-19) and temporomandibular joint disorders (TMD) as the two major diseases are being focused by the public in modern societies. Previous epidemiological studies have shown increase in TMD prevalence during COVID-19 pandemic era. This study was aimed to verify the causal association between two sides using bidirectional mendelian randomization (MR) analysis.

Temporomandibular Disorders (TMDs) are pathologies based on multifactorial etiology and a biopsychosocial model, where anxiety becomes one of the most important psychological factors as it is the most frequent symptom presented in most of the population at some point in life. Taking into account the need for a multidisciplinary approach, we set out to evaluate the possible impact of orofacial pain on patients' quality of life. In this study, the sample population FROM the Medical School of the University of Coimbra (Portugal) was evaluated using two tools: Diagnostic Criteria for Temporomandibular Disorder (DC/TMD) and an adaptation of the West Haven-Yale Multidimensional Pain Inventory.
