Active clinical trials for "Temporomandibular Joint Dysfunction Syndrome"

The aim of this research is to add to the limited body of knowledge comparing the effectiveness of ultrasound (US) to MRI diagnoses in patients with TMJ disorders. More specifically, we will review the efficacy of handheld US devices, which has not yet been done to the author's knowledge.

The aim of this study is to compare between digitally formed occlusal splints versus conventional occlusal splints in patients with TMDs regarding patient satisfaction

Bruxism is a common phenomenon. It is estimated that its prevalence in the adult population is 8-31%. Bruxism occurring during sleep is the activity of the masticatory muscles that appear during sleep, which can be rhythmic or phased and is not a movement disorder or sleep disorder in healthy people. It is currently believed that bruxism should not be considered a disorder. In healthy people, it is treated rather as behavior, which may be a risk factor for pathological clinical implications or a protective factor in the presence of other disease entities. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, periodontal and oral mucosa damage, myalgia in the stomatognathic system, headache and prosthetic restoration damage. However, due to nocturnal occurrence, bruxism symptoms may go unnoticed for a long time, which means that patients are often unaware of this behavior. The etiology of bruxism is multifactorial and not fully understood. It is currently believed that it can be caused by genetic, psychological and exogenous factors. Due to the unclear etiology of bruxism, it is so important to conduct research that allows making a certain diagnosis and finding the causes of this phenomenon

Sleep apnea is a common and serious health problem in the Polish population. According to epidemiological data problem concerns about 7% of the adult population. The most common sleep disorder is obstructive sleep apnea (OSA). The consequence of episodes of airway obstruction and sleep fragmentation is an inefficient sleep, pathological daytime sleepiness, falling asleep involuntarily, awakening with feelings of shortness of breath or throttling. The direct consequences of sleep apnea are hypoxia, increased heart rate and increased blood pressure. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. An additional problem in patients with sleep apnea is an increased incidence of bruxism. Bruxism is a common problem; reports of prevalence range from 8-31% in the general population. The most common symptoms of bruxism include: hypersensitive teeth, tooth wear, damage to dental restorations (e.g. crowns and fillings), damage to periodontal and oral mucosa, masticatory muscle pain and headaches. The etiology of bruxism is multifactorial and not fully understood. It can be caused by biologic, psychologic and exogenous factors. Arousals during the apnea episodes are considered to be a major cause of sleep bruxism in OSA patients. The relationship between OSA and sleep bruxism is still not clearly defined. Further research is needed to help explain the relationship between these two phenomena, which will enable further therapy in patients with coexisting OSA and sleep bruxism (SB).

Helkimo Index evaluates movement, joint function, pain and musculature, providing a quick general overview that could be very useful at different levels of care. The aim of this study is to investigate the validity and reliability of the Turkish version of the Helkimo index. Registration of subjective symptoms applying for the Helkimo Index required a questionnaire-based survey. Questionnaire comprised two parts: Anamnestic component which includes answers to questions in "yes" or "no". Clinical dysfunction part comprised clinical examination. Method: Turkish translation of Helkimo index will be made. The sample will consist of 100 subjects, 50 TMD patients and 50 healthy controls. the patients will be selected, demographic data were recorded: age, sex, height, weight, body mass index (BMI), educational level, work situation, smoking status, alcoholic habits and physical activity. Helkimo Index is comprised of five items, with each assessment having three possible answers, scored as 0, 1 or 5. The first item is related to the limitation in the range of jaw movement. The second item evaluates the alterations of joint function that produce deviations, sounds and/or joint locks or blockages; the third item evaluates the presence of pain when performing some movements; the fourth item evaluates muscular pain in the masticatory muscles; and the fifth item evaluates the presence of discomfort or pain in the prearticular area of the temporomandibular joint (TMJ) through palpation. From the sum of the 5 items, we identify no TMJ involvement if the score is 0, mild TMJ involvement when the score ranges from 1 to 9, moderate TMJ involvement if the score ranges between 10 and 19 and severe TMJ involvement for a score between 20 and 25. The Numerical Pain-Rating Scale (NPRS) test, disability, the Neck Disability Index test, the Dizziness Handicap Inventory (DHI), the Headache Impact Test (HIT-6) and 12-item Short-Form Health Survey (SF-12) will be assessed. Correlation will be made between the Helkimo index and these rating scales.

The aim of the study was to asses levels and relationship of chronic pain, anxiety, depression and perceived stress in TMD patients .

It is planned to examine the relationship between quality of life in patients with temporomandibular joint dysfunction and the patient's individual, physical and psychosocial characteristics.

Temporomandibular disorders (TMD) are the most common orofacial pain disorders of non-dental origin with the prevalence of 6.1-10.2%, and incidence of 3.9%. Observable pathology is mostly absent, and the etiology often remains unknown. Since some other painful conditions of unknown origin (eg. fibromyalgia), also imply genetic factors, the aim of the study is to investigate genetic predisposition in relation to the risk for TMD onset. This will be achieved through analysis of polymorphisms in the selected genes in TMD patients (DC/TMD) and matched control subjects. The possibility of involvement of specific polymorphisms in modulation of therapy response will also be investigated. The hypotheses: (I) the Single Nucleotide Polymorphism (SNPs) clustering will be dependent on presence or absence of TMD (comparison of patients with control subjects), and will possibly depend on source of pain, pain intensity, presence of bone changes, psychological features and previous orthodontic therapy, and (II) SNPs will influence the treatment response. Along with anamnestic and clinical examination and occlusal splint therapy, genomic DNA will be analyzed from the buccal swabs. Isolated DNA will be used for the determination of 19 polymorphisms of selected genes using Real-Time PCR method. The analysis of salivary oxidative stress markers and opiorphin will be also performed, as their relationship with TMD has been shown previously. This time, their concentration will be associated with polymorphisms in the promoters of genes responsible for their synthesis. The investigators expect to show that particular gene profile or group of SNPs represent a risk factor for TMD development. Innovative approach of the concept of determining the genetic predisposition for TMD has the potential for development of commercial genetic test with potential for risk estimation in relation to TMD onset. This could enable early interventions and active avoidance of environmental risk factors.

According to our previous research and clinical observation results, the motor function of the oral, maxillofacial and cervical body is closely related to the occlusal contact. Not only that, the occlusal contact also affects the psychological activities related to movement. There are many technical means to evaluate the occlusion clinically. However, the occlusion is a complex motor organ with more than 3 dimensional (including age factors) morphological characteristics, which makes the occlusion have obvious individualized characteristics. It is of great significance to objectively evaluate oral health to accurately extract occlusal contact features, analyze the relationship between occlusion and the motor function of oral, maxillofacial, neck and body as well as the corresponding psychological characteristics, and establish an evaluation method of occlusal function for evaluating motor function and psychological characteristics.
