Bruxism is a repetitive jaw-muscle activity characterized by teeth clenching and/or grinding, often associated with temporomandibular joint dysfunction, pain, and impaired jaw function. This cross-sectional comparative study aims to investigate the relationship between jaw functionality, posture, muscle stiffness, pain, perceived stress, and sleep quality in young adults with bruxism. A total of 48 participants will be included: 24 individuals with clinically confirmed bruxism and 24 healthy controls. Clinical and sociodemographic characteristics will be recorded using a Bruxism Assessment Form developed by dentists and physiotherapists. Posture will be assessed with the PostureScreen Mobile® application; pain intensity and thresholds will be measured using a digital algometer; masseter, temporalis, and trapezius muscle stiffness will be evaluated with a MyotonPro device. Perceived stress will be assessed using the Perceived Stress Scale-10, sleep quality with the Epworth Sleepiness Scale, and functional jaw limitation with the Jaw Functional Limitation Scale-20. Statistical analysis will be performed using SPSS (Version 20.0). Between-group comparisons will be made using t-tests or Mann-Whitney U tests depending on distribution. Correlation analyses (Pearson or Spearman) will be used to evaluate associations among variables. The primary outcome is to determine the relationship between jaw functionality, posture, muscle stiffness, and pain in individuals with bruxism. Secondary outcomes include the associations of sleep quality and perceived stress with these parameters. This study will provide novel insights into the multidimensional impact of bruxism and may guide future preventive and rehabilitative strategies.

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).
NCT07433595
This prospective observational case-control study aims to evaluate the association between perceived stress levels in children and their parents and the presence of clinically diagnosed bruxism in children aged 8-11 years. Children with bruxism and age-matched controls will be recruited from the Department of Pediatric Dentistry. Child perceived stress, parental perceived stress, parenting-related stress, and parental awareness of child stress/anxiety will be assessed using validated questionnaires. Associations between stress-related measures and bruxism status will be analyzed.
NCT07364552
This clinical study is designed to evaluate the effectiveness of patient-specific occlusal splints created using MODJAW, a jaw-tracking device that records 3D mandibular movements. Occlusal splints are commonly used to treat bruxism (teeth grinding) and temporomandibular joint (TMJ) disorders, which can cause jaw pain, headaches, and worn teeth. Traditional splints are made using standard designs that do not consider each patient's unique jaw movements. In this study, 40 participants with mild-to-moderate bruxism or TMJ dysfunction will be randomly assigned to two groups. One group will receive custom splints designed using MODJAW kinematic data, while the other group will receive standard occlusal splints. Participants will use their assigned splint for 8 weeks. The study will measure: Jaw movement patterns using MODJAW TMJ pain levels Patient comfort and satisfaction The main goal is to determine whether MODJAW-based, patient-specific splints provide better jaw function, reduced pain, decreased teeth grinding, and higher patient satisfaction compared to standard splints. Participants will be monitored throughout the study to ensure safety, comfort, and proper splint use. This study is expected to help dentists design more effective, personalized splints in the future and improve treatment outcomes for people with jaw disorders or bruxism.
NCT06153810
The overall objective of the clinical investigation is to evaluate whether the use of the AesyBite Active reduces the bruxism activity.
NCT07241728
This study was designed to investigate the effectiveness of diadynamic current, one of the electrotherapy methods added to rehabilitation in the treatment of bruxism. Individuals over the age of 18 diagnosed with bruxism will be randomly assigned to one of the following groups using the sealed envelope method: rehabilitation program (control group) or rehabilitation program combined with diadynamic current (experimental group). The intervention will consist of an exercise program conducted jointly for the experimental and control groups. Participants will be given a structured exercise program to be performed in person 3 days a week for 6 weeks. In addition to the exercise program, the experimental group will receive diadynamic current treatment at each session. Pain intensity will be assessed using the Visual Analog Scale (VAS), pressure pain threshold with an algometer, muscle strength with a hand-held dynamometer, bite force with a pinch meter, maximal mouth opening with a caliper, and head posture with the craniovertebral angle. Oral habits will be evaluated using the Oral Behavior Checklist, and anxiety levels will be assessed with the State-Trait Anxiety Inventory (STAI).

Participants will: Attend sessions to learn diaphragmatic breathing exercises Practice these exercises daily at home for 4 weeks Complete questionnaires and clinical assessments before and after the program Participation is safe, with minimal risks, such as mild fatigue during exercises. The study will help determine if diaphragmatic breathing is an effective way to manage sleep bruxism
NCT07090551
The study group will be selected from patients who previously presented with various temporomandibular disorder (TMD) complaints to the "Temporomandibular Disorders Clinic" of the Department of Complete and Removable Dentures at the Faculty of Dentistry, Istanbul University. During routine examinations, TMD-DC (Diagnostic Criteria for Temporomandibular Disorders) forms are completed to aid in achieving an accurate diagnosis. Subsequently, patients suspected of having TMD of masticatory muscle origin but without a definitive diagnosis are routinely referred for ultrasonographic (USG) imaging. Patients meeting these criteria will be included in the study. Participants will be divided into two groups. The first group will consist of patients who have already undergone USG imaging during their routine examination, have been definitively diagnosed with masticatory muscle disorders based on clinical and radiographic findings, and have initiated routine occlusal splint therapy in the clinic. The 12-week treatment process of these patients will not be altered in any way. At the final follow-up session after the 12-week routine treatment protocol, the TMD-DC form completed at baseline will be re-administered, and the two forms will be compared to evaluate changes in symptoms and pain levels. Another USG imaging will also be performed at this session. The second group, serving as the control group, will include patients who have previously undergone USG imaging during routine examination and have received a definitive diagnosis of masticatory muscle disorders based on clinical and radiographic evaluations, but have not yet begun treatment. Patients whose turn for treatment begins during the study period will be excluded from this group. At the end of the 12-week period, the TMD-DC form will be re-administered, and a second USG imaging will be performed. This process will not interfere with the patients' position in the treatment queue, and treatment will commence as scheduled. In the second USG session, changes in the thickness and elasticity of the masseter, temporalis, trapezius, sternocleidomastoid, and splenius capitis muscles will be assessed by comparing the two imaging records.
NCT07074964
Introduction: Sleep bruxism is defined as the repetitive activity of the masticatory muscles, characterized by clenching or grinding of the teeth. Studies confirm the association between sleep bruxism and episodes of masticatory muscle activity, with an increase in autonomic sympathetic activity observed during transient periods of sleep. This is associated with nocturnal awakenings, related to increased cardiac, cerebral (cortical arousal), respiratory, and muscular activity. Objectives: The main objectives are "To study the mean power frequency (MPF) of the masticatory muscles measured by surface electromyography (sEMG) in the general population (with and without bruxism according to ICSD-3 and DC/TMD criteria)"; and "to assess the effectiveness of manual therapy applied to structures adjacent to the vagus nerve based on its impact on orofacial pain and symptomatology in patients with bruxism". Material and Methods: A cross-sectional observational study and a randomized controlled experimental study were designed. The first will analyze data collected by sEMG in the masticatory muscles, at rest and during maximum clenching, comparing results between bruxists and non-bruxists. The second will analyze, compared to the control group, data collected on signs (range of motion alteration, presence of sounds), symptomatology (pain, headaches, sensation of blockage, functional limitation) caused by bruxism, sleep quality (Pittsburgh Sleep Quality Index (PSQI)), oral health-related quality of life (OHIP-14), stress and anxiety status (Perceived Stress Scale and GAD-7 (Generalized Anxiety Disorder-7), respectively), and sympathetic-vagal balance (Heart Rate Variability in its frequency and time domains) before and after a manual therapy intervention on structures adjacent to the vagus nerve pathway (head, neck, thorax, diaphragm, abdomen). The collected data will be analyzed using IBM SPSS® version 25.0.0.
NCT07051876
The purpose of this research is to determine whether a clinical trial assessing the impact of physiotherapy and mouthguards on bruxism is feasible. This includes evaluating the feasibility of participant recruitment, implementing the interventions, and collecting data using appropriate techniques. The study will focus on posture angle analysis to assess changes in posture associated with bruxism, and electromyography (EMG) to measure muscular activity. By examining these elements, the study aims to lay the groundwork for a larger clinical trial that could provide conclusive evidence regarding the efficacy of these therapies in treating bruxism. Participants will be recruited from the USJ dental clinics following their consultation. They will be screened for bruxism using a questionnaire and a clinical examination based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). The mouthguard-only group will receive a custom-fitted mouthguard, fabricated by a qualified dentist. Participants will be instructed to wear the mouthguard during sleep for six weeks, to clean it daily, and to store it in a cool, dry place. The mouthguard and physiotherapy group will receive both a custom-fitted mouthguard and physiotherapy. The home physiotherapy program will include posture improvement exercises, relaxation techniques, and muscle therapy targeting the head, neck, and shoulders. Participants will perform the exercises daily at home, record themselves, and submit the videos each day via a social platform (e.g., Microsoft Teams or WhatsApp, depending on patient preference) for a period of six weeks.

Ecological momentary assessment (EMA) interventions via mobile devices can be implemented to monitor an individual's negative health behaviors in real-time, increase awareness, and assist patients in overting those behaviors. In recent years, EMA interventions have been used to improve patients' awareness of specific oral behaviors, such as tooth clenching or awake bruxism, which can produce excessive forces on the muscles of mastication and lead to or exacerbate symptoms of temporomandibular disorders (TMD). Yet, whether EMA interventions are effective in reducing oral behaviors and masticatory muscle activity in the short- and long-term, or whether they are more effective than patient education remains unclear. In this randomized clinical trial, we aim to test the effects of a 1-week EMA intervention combined with structured information on masticatory muscle activity and determine whether a combined approach including an EMA intervention and structured information is more effective in reducing masticatory muscle activity than structured information alone. Our study will have a significant impact on orofacial pain clinical research as it will provide clinically relevant measures which could inform multimodal approaches for the management of painful TMD.

NCT06937333
Bruxism is defined as a repetitive jaw muscle activity characterized by clenching and grinding teeth caused by mandibular movement. Sleep bruxism is frequently seen and can affect the quality of life of individuals. Since bruxism is characterized by clenching teeth, it can cause pain. However, the relationship between bruxism and pain has not been sufficiently studied in the literature. The relationship between the temporamandibular joint and the cervical region is known. However, the relationship between bruxism and cervical mobility is not clear. Since there may be temporamandibular joint problems in bruxism, it can affect joint movement. The sleep quality of individuals may decrease and this may lead to problems in functionality. However, when the literature is examined, the relationship between bruxism and functional independence in children has not been explained. Therefore, the aim of the study was to compare the pain, range of motion, sleep quality and functional independence of children with bruxism and healthy controls.
NCT06450782
Bruxism is a repetitive jaw muscle activity that occurs during sleep or while awake, characterized by teeth clenching or grinding. Bruxism affects millions of people worldwide and is considered one of the most harmful activities for the stomatognathic system due to its morphological, pathophysiological, psychosocial features and clinical consequences. Repetitive teeth clenching and grinding movements can cause spasms, stiffness, pain, and activity changes in the chewing muscles. Since bruxism is a disorder that depends on many variables, there is no single, specific treatment and multidisciplinary approaches are often required. Most treatment strategies are conservative and symptomatic, aiming to prevent the consequences of the disorder. The main purpose of physiotherapy techniques is to reduce the negative effects of bruxism on the chewing system. Physiotherapy techniques include exercises, manual therapy, electrotherapy, acupuncture, and posture awareness. It is not clear in the literature which physiotherapy techniques are effective in the management of bruxism; Therefore, more controlled studies need to be conducted. When studies in the literature are examined, no studies have been found that objectively investigate the effectiveness of relaxation techniques alone in people with muscle pain and increased muscle stiffness due to teeth clenching problems. Within the scope of this project, it is planned to investigate the effectiveness of the myofascial release technique (MRT) and post-isometric relaxation technique (PİRT) using the grastone tool.
NCT06914388
This study aim to evaluate the effects of a 6-week self-management program on pain, muscle stiffness, and temporomandibular joint (TMJ) functions in sedentary individuals aged 18-40 with bruxism. Thirty-five individuals will be evaluated. Bruxism will be assessed using the Bruxism Assessment Questionnaire, while temporomandibular joint dysfunction (TMJD) will be evaluated using the Helkimo Clinical Dysfunction Index and the Fonseca Questionnaire. Masseter muscle pain threshold will be measured with a digital algometer, muscle stiffness with a Shore Durometer, mandibular depression range of motion with a bicondylar caliper, and TMJ proprioception with TMJ position sense. Assessments will be conducted pre-intervention and at the end of the fourth week.

Sleep disordered breathing is a common and serious health problem. According to epidemiological data, it may affect about 20% of adult population. The majority is not aware of the disease. The most common sleep disorder is obstructive sleep apnea (OSA). The essence of OSA are the episodes of airway obstruction repeated many times during sleep, as a result of which the level of partial oxygen in the blood decreases. Apnea episodes end up waking from sleep, causing sleep fragmentation, deep sleep and REM deficiency. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. Comorbid Insomnia and Sleep Apnea (COMISA) is a highly prevalent and debilitating disorder that causes additional disturbances in sleep, daytime functioning, and quality of life for patients, and is a significant diagnostic and therapeutic problem for clinicians. Although the presence of COMISA was first noticed by Christian Guilleminault and his colleagues in 1973, it received very little research attention for almost three decades. There is still lack ofclinical trials concerning this topic. An additional problem in apnea patients is the increased incidence of bruxism. Bruxism is associated with increased masticatory muscle activity during sleep, which may be phased or tonic. It is estimated that the incidence of bruxism in the adult population is 13%. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, damage to the periodontium and oral mucosa, muscle pain in the stomatognathic system, headaches and damage to prosthetic restorations. However, the symptoms of bruxism can go unnoticed for a long time, leaving patients often unaware of the problem. The aim of this project is: 1. to determine the prevalence of sleep bruxism in COMISA, OSA and insomnia, 2. to examine of arousals (type, frequency) in COMISA, OSA and insomnia, 3. to investigate the relationship between arousals and blood pressure values and variability, arrhythmias, sinus rhythm variability, vascular endothelial dysfunction, cardiovascular risk in COMISA, OSA and insomnia.
NCT06894472
This study examines the effect of electromyography biofeedback on masticatory muscles hyperactivity on patients with bruxism.

Each eligible patient will be randomly into one of two groups: Group A: The digital splint group, digital splint will be constructed to each patient. Group B: The conventional splint group, conventional splint will be constructed to each patient. * For both groups, thorough clinical examination, scaling and root-planning will be done. Patient will receive a motivational oral hygiene program with detailed explanation regarding the study process and outcome expectations. * A precise history and clinical examination will be done by (F.M) under supervision of Dr S.G. The digital splint construction method: * First, complete arch intraoral digital scans of the maxillary and mandibular arches will be performed using the intra oral scanner following the scanning protocol recommended by the manufacturer. * For inter maxillary relation recording using optical jaw tracking device, step-by-step procedure for tracking and recording the maxillomandibular relationship and mandibular motion by using an optical jaw tracking system will be illustrated to the patient. * The occlusal device will be designed using a CAD software program. * The occlusal device will be printed using a 3D printer * The occlusal device will be finished and polished manually. The conventional splint construction method: * The first step is making an impression using a quick-setting addition polyvinyl siloxane impression material. A stone model will be obtained after pouring the impression using extra-hard dental stone. * In the second visit a face bow transfer and a centric relation record will be utilized to mount the casts on a semi adjustable articulator. * For centric relation recording, a jig will be made with an incisal plateau from modeling plastic impression compound and the jig will be inserted between the central incisors. To measure centric relation as precisely as possible (by avoiding translational movement in the temporomandibular joint), * The jig will be adjusted with a scalpel to create a distance of no more than 2 mm between the maxillary and mandibular arches. Then the relation will be recorded using a fast-setting polyvinyl siloxane occlusal registration material. The occlusal registrations will be trimmed to the buccal cusp tips to be transferred accurately to the articulator without interference. * After mounting of the centric relation the protrusive record will be taken and the horizontal condylar angle will be adjusted accordingly. * The device will be fabricated from clear prosthetic resin. Production followed a standardized protocol with a minimum inter maxillary thickness of 1.5 mm and a buccal extension to 1 mm below the survey line. * The device will be finished and occlusion will be adjusted on the articulator. outcomes assessment: 1. Occlusal force distribution will be measured using osslusosense. 2. Cost effectiveness will be assessed using the following equation(CE ratio = C/E).
NCT06583044
Clinical students in the Faculty of Dentistry were diagnosed with bruxism according to the bruxism assessment consensus 2018. A total of 128 students with (64) and without (64) bruxism, were asked 33 questions about their knowledge and self-awareness about bruxism.
