BACKGROUND: The stress experienced as an intense and traumatic event can increase the odds of orofacial pain, affect the biomechanics of masticatory system and compromise the periodontal health. This study was conducted to investigate the impact of post-traumatic stress disorder (PTSD) on oral health. METHODS: A case-control study with a convenience sample was designed. Probing pocket depth (PPD), clinical attachment level (CAL), bleeding on probing, and plaque were recorded at 6 sites per tooth...

Frequent involvement of the disc in temporomandibular joint (TMJ) disorders warrants attempts to tissue engineer TMJ disc replacements. Physiologically, a great degree of similarity is seen between humans and farm pigs (FPs), but the pig's rapid growth confers a significant challenge for in vivo experiments. Minipigs have a slower growth rate and are smaller than FPs, but minipig TMJ discs have yet to be fully characterized. The objective of this study was to determine the suitability of the minipig for TMJ studies by extensive structural and functional characterization...

It is estimated that 2% to 4% of the US population will seek treatment for temporomandibular joint (TMJ) symptoms, typically occurring with anterior disc displacement. The temporomandibular retrodiscal tissue (RDT) has been postulated to restrict pathologic disc displacement. To elucidate RDT function, understanding regional RDT biomechanics and ultrastructure is required. No prior biomechanical analysis has determined regional variations in RDT properties or associated biomechanical outcomes with regional variations in collagen and elastin organization...

Myofascial pain of the muscles of mastication is a common temporomandibular disorder. Patients unresponsive to conservative treatment modalities pose a therapeutic challenge to the treating clinician. The efficacy of intramuscular botulinum toxin injections for recalcitrant cases is still not well established due to mixed results from clinical trials. The Diagnostic Criteria of Temporomandibular Disorders (DC/TMD) classified chronic muscle pain broadly into a localized pattern (when pain is localized to the site of palpation or the muscle palpated) and a referring pattern (when the pain spreads beyond the boundary of the muscle being palpated)...

Temporomandibular disorders (TMDs) are the most frequent non-dental orofacial pain disorders and may be associated with rheumatoid arthritis (RA), resulting in oropharyngeal dysphagia (OD). However, clinicians' understanding of involvement with OD caused by RA-related TMDs is limited and the methodological quality of research in this field has been criticised. Therefore, the aim of this study was to systematically review the prevalence of oral preparatory and oral stage signs and symptoms of OD in adults presenting with TMDs associated with RA...

When a dysfunction occurs in any component of the stomatognathic system, temporomandibular disorders (TMD) may originates. The aim of this study was to compare the deviations, displacement, and the execution speed of mandibular movements among asymptomatic participants and those with TMD. Convenience sampling was used; forty participants diagnosed by clinical evaluation following the Research Diagnostic Criteria for Temporomandibular Disorders were divided into three groups: Arthropathy (GART, 10 participants, 40% men), Myopathy (GMYO, 10 participants, 30% men), and the Control Group (CG, 20 asymptomatic-participants, 25% men)...

Temporomandibular joint disorder (TMD) is a broad pain disorder that refers to several conditions affecting the temporomandibular joint of the jaw and the muscles of mastication. As with most pain disorders, a high prevalence of depression and anxiety is associated with TMD. Research has shown that selective serotonin reuptake inhibitors (SSRIs), the first-line drug therapy for major depressive disorder, may not be suitable for TMD patients because SSRIs can induce teeth-grinding, otherwise known as bruxism...

Temporomandibular disorder (TMD) is a complex and multifactorial disease, with inflammatory response and cartilage destruction usually associated with its etiology. Notch1 is a type I transmembrane receptor, which is critical in determining the growth, differentiation and survival of various cell types. However, its role and mechanism in interleukin (IL)‑1β‑stimulated temporomandibular chondrocytes remain to be elucidated. In the present study, chondrocytes were isolated from Sprague‑Dawley rats and stimulated by IL‑1β at a concentration of 10 ng/ml, and the expression of Notch1 was inhibited by small interfering RNA...

PURPOSE: Although indications for the surgical treatment of internal derangement of the temporomandibular joint (TMJ) and the choice of treatment are debated, arthroscopy seems generally accepted as a minimally invasive alternative. The objective of this study was to investigate various factors and their possible correlation with an unsuccessful outcome of arthroscopic lysis and lavage in patients diagnosed with chronic closed lock, arthralgia with or without concomitant osteoarthritis of the TMJ, or systemic rheumatologic disease with involvement of the TMJ...

Temporomandibular disorder (TMD) is ranked the second leading cause of orofacial pain after toothache, and there is no effective standard treatment for all cases. Therefore, much research has been conducted in the therapeutic areas of TMD, such as acupuncture and electrotherapy, for this purpose. The aim of this research was to evaluate application of the neuromagnetic stimulator device Haihua model CD-9, used within the precepts of acupuncture in treating TMD-related pain symptoms and limited mouth opening...

Study Objectives: Sleep bruxism (SB) is considered as a possible etiological factor for Temporomandibular Disorder (TMD) pain. However, polysomnographic (PSG) studies, which are current "gold standard" diagnostic approach to SB, failed to prove an association between SB and TMD. A possible explanation could be that PSG studies have considered only limited characteristics of SB activity: the number of SB events per hour and, sometimes, the total duration of SB per night. According to the sports sciences literature, lack of adequate rest-time between muscle activities leads to muscle overloading and pain...

BACKGROUND AND AIM OF WORK: posture is the position of the body in the space, and is controlled by a set of anatomical structures. The maintenance and the control of posture are a set of interactions between muscle-skeletal, visual, vestibular, and skin system. Lately there are numerous studies that correlate the muscle-skeletal and the maintenance of posture. In particular, the correction of defects and obstruction of temporomandibular disorders, seem to have an impact on posture. The aim of this work is to collect information in literature on posture and the influence of the stomatognathic system on postural system...

Giant cell tumor (GCT) of the craniofacial bones has been reported but they are not common. This tumor occurs more often in women than in men and predominantly affects patients around the third to fifth decade of life. GCTs are generally benign but can be locally aggressive as well. We report a case of GCT involving the temporomandibular joint (TMJ), which was initially thought to be temporomandibular disorder (TMD). A 22-year-old female presented with swelling and pain over the right temporal region for 18 months associated with jaw locking and clicking sounds...
