The aim was to determine predictors for the development of complaints of temporomandibular disorders (TMD) in a large sample of Dutch scuba divers who were free of any TMD complaints before they started diving actively. Five-hundred and thirty-six scuba divers (mean ± SD age = 40.4 ± 11.9 years; 34.1% women) completed a specifically developed questionnaire, either online or on paper. Stepwise forward logistic regression analysis was performed to predict the presence of TMD pain, with several potential risk factors as predictors. Four hundred and eighty-five of the 536 respondents were free of any TMD pain before they started diving actively. In this sample, TMD pain was present in 214 persons (44.1%). Four predictors contributed significantly to the presence of TMD pain, viz., clenching (OR = 2.466), warm water (OR = 1.685), biting on the mouthpiece (OR = 1.598), and the quality rating of the mouthpiece (OR = 0.887, that is, a higher rating means a smaller odds of having TMD pain). TMD pain is a common complaint among scuba divers who were free of such complaints before they started diving actively. Clenching, biting on the mouthpiece, and a low rating of the mouthpiece are predictors for the presence of TMD pain in scuba divers, while diving in cold water serves as a protective factor for TMD pain.

Background/purpose: Chewing difficulty can contribute to psychological stress, which reduces the quality of life for older adults. The purpose of this study was to investigate and analyze the severity of masticatory discomfort, stress response, and sleep disturbance in older patients experiencing masticatory discomfort due to tooth loss or temporomandibular disorders (TMD), to find the further treatment direction for these patients.
Materials And Methods: A total of 392 patients aged 50 years and older with mastication difficulties were analyzed.

Background: The temporomandibular joint (TMJ) is a unique joint that enables mandibular movement. Temporomandibular diseases (TMDs) impair joint function, leading to more or less specific clinical signs.
Objectives: To compile and disseminate clinical data and research findings from existing publications on equine TMD.

: Interincisive midline deviation is frequent. Determining the cause (dental versus skeletal) is crucial for treatment planning. This study assessed the null hypothesis that neither clinical dental midline shift nor the temporomandibular disorder (TMD)-affected side correlate with maxillary/mandibular asymmetry.

Objective: To develop a clinical automated diagnostic system for temporomandibular disorders (TMD) based on the diagnostic criteria for TMD (DC/TMD) to assist dentists in making rapid and accurate clinical diagnosis of TMD.
Methods: Clinical and imaging data of 354 patients, who visited the Center for TMD & Orofacial Pain at Peking University Hospital of Stomatology from September 2023 to January 2024, were retrospectively collected. The study developed a clinical automated diagnostic system for TMD using the DC/TMD, built on the.

C-type natriuretic peptide (CNP) can be a new disease-modifying anti-osteoarthritis drug (DMOAD) candidate because intraarticular injection of CNP attenuates both articular cartilage degradation and persistent pain in a rat knee arthritis model. This study aimed to elucidate the underlying molecular mechanisms by which CNP protects the knee joint from osteoarthritic changes. Gene expression analyses indicated that CNP did not interfere with the expression of IL1β -responsive genes in rat primary synovial fibroblasts or the monocytic cell line, RAW264.
