Association between generalized joint hypermobility, temporomandibular joint hypertranslation and temporomandibular disorders: a scoping review.

Generalized Joint Hypermobility (GJH) is one of the pathophysiological contributing factors for the development of temporomandibular disorders (TMD). There are, however, several counterpoints on the potential relation between TMD and joint hypermobility, especially when considering the temporomandibular joint (TMJ), event known as TMJ hypertranslation. Additionally, there is no consensus regarding the clinical and imaging diagnostic criteria for such condition.

Custom-Made Mouthguard: Personalized Solution for Injury Prevention Secondary to Bruxism During Physical Activity.

The natural dynamics of the jaw during physical activity and its physiological mechanisms are not fully understood. However, teeth clenching during certain sports activities may be associated with increased strength, power, flexibility, and performance. This behavior is termed awake bruxism (AB) and can lead to intraoral damage, highlighting the importance of patient education and management.

Comparative analysis of temporomandibular joint morphology in degenerative joint disease: A cone-beam CT study in patients with and without arthralgia.

Unlabelled: This cross-sectional study aimed to compare, by using Cone-Beam Computed Tomography (CBCT), temporomandibular joint (TMJ) morphology among patients with degenerative joint disease (DJD) with or without arthralgia, as well as a control group.

Methods: Thirty-one patients and their respective CBCT TMJ exams were assessed. These individuals were selected from an Orofacial Pain Service and classified into three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): group 1 (10 patients with TMJ DJD and arthralgia), group 2 (11 patients with TMJ DJD without pain), and group 3 (the control group, consisting of 10 healthy individuals without any signs or symptoms of TMD).

Secondary bruxism: A valid diagnosis or just a coincidental finding of additional masticatory muscle activity? A narrative review of literature.

Introduction: Bruxism is defined as a repetitive masticatory muscle activity that can manifest it upon awakening (awake bruxism-AB) or during sleep (sleep bruxism-SB). Some forms of both, AB and SB can be associated to many other coexistent factors, considered of risk for the initiation and maintenance of the bruxism. Although controversial, the term 'secondary bruxism' has frequently been used to label these cases.

Insights for temporomandibular disorders management: From psychosocial factors to genetics-A case report.

Aims: This case report aimed to discuss the multifactorial etiology and also the management of temporomandibular disorders (TMD) by addressing important associated psychosocial and biological factors, emphasizing the interaction between these factors and a probable genetic predisposition.

Methods And Results: A 21-year-old female patient was evaluated according to Research Diagnostic Criteria for TMD and diagnosed with arthralgia, myofascial pain, disc displacement without reduction, and temporomandibular joint (TMJ) degenerative disease. TMJ alterations were confirmed through magnetic resonance imaging and cone-beam computed tomography.

Temporomandibular joint morphology does not influence the presence of arthralgia in patients with disk displacement with reduction: a magnetic resonance imaging-based study.

Objective: The aim of this study was to compare, by using magnetic resonance imaging (MRI), temporomandibular joint (TMJ) morphology between patients with disk displacement with reduction (DDWR) with or without arthralgia and a control group and to identify which factors are associated with the concomitant presence of arthralgia in DDWR patients.

Study Design: In this investigation, 36 TMJ MRIs were divided into 3 groups. Group 1 (n = 12) comprised patients with DDWR and arthralgia; group 2 (n = 12) comprised patients with DDWR without arthralgia; and group 3 (n = 12) was the control group.

Is quality of life affected by temporomandibular disorders?

Objective: To determine the impact of temporomandibular disorders in quality of life.

Methods: A total of 102 volunteer patients (68 female) aged 19 to 86 years, who sought medical care in health clinics of the university and were evaluated in the period from September to December 2013. The subjects were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders, using a mechanical algometer (Palpeter®) with standardized pressure of 0.

The influence of myofascial temporomandibular disorder pain on the pressure pain threshold of women during a migraine attack.

Aims: To assess the influence of myofascial temporomandibular disorder (TMD) pain on the pressure pain threshold (PPT) of masticatory muscles in women during a migraine attack.

Methods: The sample comprised 34 women, 18 to 60 years of age, with a diagnosis of episodic migraine previously confirmed by a neurologist. All subjects were evaluated using the Research Diagnostic Criteria for TMD (RDC/TMD) to determine the presence of myofascial pain.

Bilateral asymptomatic fibrous-ankylosis of the temporomandibular joint associated with rheumatoid arthritis: a case report.

The American Academy of Orofacial Pain (AAOP) defines ankylosis of the temporomandibular joint (TMJ) as a restriction of movements due to intracapsular fibrous adhesions, fibrous changes in capsular ligaments (fibrous-ankylosis) and osseous mass formation resulting in the fusion of the articular components (osseous-ankylosis). The clinical features of the fibrous-ankylosis are severely limited mouth-opening capacity (limited range of motion during the opening), usually no pain and no joint sounds, marked deflection to the affected side and marked limitation of movement to the contralateral side. A variety of factors may cause TMJ ankylosis, such as trauma, local and systemic inflammatory conditions, neoplasms and TMJ infection.

Orofacial pain and temporomandibular disorders: the impact on oral health and quality of life.

Many conditions may cause painful symptoms in orofacial structures. Among the chronic conditions that affect this area, temporomandibular disorders are the most common. Temporomandibular Disorder is a collective term that includes a number of clinical complaints involving the masticatory muscles, the Temporomandibular Joint and associated structures.
