Purpose: The purpose of this study was to assess temporomandibular function after condylectomy because of unilateral condylar hyperactivity (UCH) by means of standardized diagnostic criteria. The results were compared with those obtained in a control group.
Patients And Methods: In this study, 33 patients with UCH who underwent condylectomy and 31 controls matched for age and gender filled out a history questionnaire and underwent a clinical examination as part of the research diagnostic criteria for temporomandibular disorders. Data analysis was performed by use of the Fisher exact test for 2-by-2 tables.
Results: Patients and controls did not differ significantly regarding myofacial pain (P = .131), disc displacement (P = .516), and depression (P = .34). The groups differed significantly concerning arthralgia, osteoarthritis, and osteoarthrosis (P = .003), as well as pain with low disability (P = .022).
Conclusions: In patients with UCH who underwent condylectomy because of progressive mandibular asymmetry, more joint-related temporomandibular problems as well as more postoperative pain developed when compared with age- and gender-matched controls. However, these problems did not lead to more severe disabilities in daily life.

Background: Operative treatment of advanced mandibular tumors may require excision of a portion of the mandible including the condyle. It is not clear how condylar excision affects postoperative quality of life (QoL).
Purpose: The study purpose was to measure the association between operative management of the condyle and postoperative health-related QoL and temporomandibular joint (TMJ) function.

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.

Septic arthritis occurring in the temporomandibular joint (TMJ) has received significantly less attention than it deserves. This condition can severely compromise joint functionality, especially if left untreated. Its typical presentation includes pain, fever, swelling, and the loss of TMJ functions.

This article outlines the orthodontic treatment of a 21-year-old female patient with an open bite and temporomandibular joint disorders (TMDs) that developed after a severe car accident. The treatment plan utilized temporary anchorage devices (TADs) for upper molar intrusion to correct the open bite without resorting to orthognathic surgery. Over a period of 3 years, the treatment achieved a stable occlusion, normalized molar relationships, and improved esthetics.

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.
