Case series summary This report summarises and reviews the published cases of open-mouth jaw locking in cats and describes three further cases. Case 1 was a 5-year-old, 5.3 kg male neutered domestic shorthair cat. CT identified changes consistent with temporomandibular joint (TMJ) dysplasia with osseous degenerative changes, and the cat subsequently underwent bilateral partial zygomectomy with bilateral partial coronoidectomy. Case 2 was a 10-year-old, 6.0 kg male neutered Exotic Shorthair. Aside from a fracture of the left maxillary canine tooth crown and absence of the left maxillary fourth premolar tooth, no abnormalities were found on CT scan...

This study assessed 24 adult patients, suffering from severe chronic unilateral pain diagnosed as temporomandibular joint (TMJ) disorder (TMD). The full dentate patients had normal occlusion and had never received an occlusal therapy, i.e., were with natural dental evolution/maturation. The following functional and dynamic factors were assessed: (1) chewing function; (2) TMJ remodeling or the condylar path (CP); and (3) lateral jaw motion or lateral guidance (LG). CPs were assessed using conventional axiography, and LG was assessed by K7 jaw tracking...

Tuberculosis (TB) is a very common health problem in developing nations such as India. It can present as its primary form or as secondary forms (extrapulmonary TB). Maxillofacial manifestations of TB compose nearly 10% of all extrapulmonary manifestations of the disease. Extrapulmonary TB involving the maxillofacial region is very rare and can present in any tissues in this region. These infections generally involve the head and neck through hematogenous or lymphatic routes. Very few cases of primary TB of the temporomandibular joint (TMJ) have been reported in the literature...

INTRODUCTION: Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder. That condition can result in pain otologic symptoms. OBJECTIVE: The aim of the present study was to investigate the relationship between temporomandibular disorder and both otologic symptoms and bruxism...

Neurofibromatosis type 1 (NF-1) is a genetic disease with characteristic neurofibromas and bony dysplasia that manifest throughout the body, including the craniofacial region. NF-1 patients are known to frequently report chronic pain in areas below the head; however, the matter of pain in the craniofacial region in this patient group has not been handled intensively so far, and studies have mainly focused on headaches. This article comprehensively reviews the related literature and reports a case of an NF-1 patient whose chief complaint was headache and pain in the temporomandibular joint area...

The development of animal models for research has been very diffused. Osteoarthritis is a joint degenerative pathology that induces cartilage erosion, chondrocyte proliferation and osteophyte formation. The aim of this paper is to present a technical procedure to perform the injection of monosodium iodine acetate in the temporomandibular joints of rats to generate osteoarthritis and to contribute to future research analysis related to pathology progression and proper treatment performance. The use of rat models may be a complex process because of their size, but they can be compared to the human temporomandibular joint due to the similar characteristics and the possibility of performing diagnosis and treatment protocols in order to detect this pathology...

This case report describes computer-guided occlusal therapy in a patient who met the unified diagnostic criteria for phantom bite. After a review of the patient's medical history, along with a diagnostic work-up that included cone beam computed tomography, temporomandibular joint vibration analysis, and digital occlusal analysis, problematic dental components were discovered (including prolonged disclusion time and imbalanced bite force). A digital occlusal analyzer evaluated the patient's occlusion and systematically guided the necessary changes...

Hemifacial hyperplasia is a rare developmental anomaly characterized by marked unilateral facial tissues. It involves orofacial soft tissues, bones of the face, and teeth. The cause remains ambiguous although several predisposing factors have been reported. A case report of a 32-year-old girl with unilateral hemifacial enlargement, pain in temporomandibular joint, and limited mouth opening associated is presented to highlight the clinical and imaging findings and to discuss the differential diagnosis.

OBJECTIVES: The temporomandibular joints (TMJs) are frequently affected in children with juvenile idiopathic arthritis (JIA). Early detection is challenging, as major variation is present in scoring TMJ pathology on Magnetic Resonance Imaging (MRI). Consensus-driven development and validation of a MRI scoring system for TMJs has important clinical utility in timely improvement of diagnosis, and serving as an outcome measure. We report on a multi-institutional collaboration towards developing a TMJ MRI scoring system for JIA...

According to epidemiological data, muscular dysfunctions of the masticatory system occur in 15-23% of the population. Preventive examinations of functional disorders of the stomatognathic system are, therefore, of particular importance. A distinct group of patients exposed to dysfunctions in the area of the masticatory organ locomotor apparatus comprises those with genetic diseases characterised by disorders in collagen formation. One of such diseases is osteogenesis imperfecta (OI) and dentinogenesis imperfecta that usually goes together with the former...
