This article describes the assessment of psychological status and quality of life in 41 patients with temporomandibular joint (TMJ) dysfunction as well as the importance of the disease for patients. The study revealed a number of personal characteristics and emotional problems in TMJ dysfunction patients, such as increased anxiety and low level of psychological stability.

Objectives: In this study, artificial intelligence techniques were used to achieve automated diagnosis and classification of temporomandibular joint (TMJ) degenerative joint disease (DJD) on cone beam computed tomography (CBCT) images.
Methods: An AI model utilizing the YOLOv10 algorithm was trained, validated and tested on 7357 annotated and corrected oblique sagittal TMJ images (3010 images of normal condyles and 4347 images of condyles with DJD) from 1018 patients who visited Peking University School and Hospital of Stomatology for temporomandibular disorders and underwent TMJ CBCT examinations. This model could identify DJD as well as the radiographic signs of DJD, namely, erosion, osteophytes, sclerosis and subchondral cysts.

Aims: To verify the possible association between the stomatognathic and the visual system by analyzing the effects that different mandibular postures may have on the accommodative capacity and ocular convergence and by assessing whether temporomandibular disorders (TMD) can influence visual abilities.
Materials And Methods: A case-control study was performed during a 1-year period on a sample of 100 subjects (50 cases and 50 controls). The subjects underwent a gnathological examination, and two visual tests were performed in three different jaw positions: maximum intercuspation, resting position, and open mouth.

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.

Objectives: Temporomandibular joint osteoarthritis (TMJ-OA) with condylar resorption is a multifactorial condition involving hormonal imbalance and articular disk dysfunction, often leading to severe TMJ degeneration. This study investigated the combined effects of estrogen deficiency and anterior articular disk derangement (ADD) on condylar bone resorption in a mouse model.
Methods: Female C57BL/6J mice underwent ovariectomy (OVX) to induce estrogen deficiency and ADD was surgically induced for stress.

Orexin-A (OXA), a neuropeptide produced in the hypothalamus, is recognized for its role in modulating orofacial nociception and regulating feeding behaviors, as well as its impact on psychophysiological responses. This study investigated the role of orexin-1 receptors (OX1R) in modulating nociceptive behaviors induced by noxious stimulation of the temporomandibular joint (TMJ) and the associated changes in mood and feeding behaviors in rats with complete Freund's adjuvant (CFA)-induced temporomandibular disorders (TMDs). Bilateral cannulation of the lateral ventricles was performed in rats.
