Filter by: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.
Occlusal splints are employed in the treatment of sleep bruxism. These appliances decrease sleep-related actions and damages bruxism, like grinding, tooth-wear, headache, and temporomandibular joint disorders. Occlusal splints are produced both in hard and soft forms according to the used material. In this study, it was aimed to evaluate the effect of occlusal splint type on the sleep quality and occlusal force parameters of patients with sleep bruxism.
The aim of the study was to assess and compare the relationship between jaw function, neck disability, sleep quality, fatigue, and headache in patients with myofascial Temporomandibular Disorder (TMD) with Sleep Bruxism (SB) and without (non-SB).
The purpose of this study is to test whether severe masticatory muscle spasms during sleep (e.g. teeth clenching and grinding, known as "bruxism" in technical jargon) demonstrably decrease after application of botulinum toxin type A (Xeomin®). Xeomin® has so far been used to relieve spasms of other muscles and is an approved drug in Switzerland. This study is now intended to test the suitability of this drug for relaxation of the masseter muscle.
The aim of the study is to evaluate the efficacy of sleep hygiene measures for the possible improvement of sleep bruxism in children through a randomized controlled clinical study of children under 8 years of age with probable sleep bruxism. In randomization both groups will receive information about bruxism, and the test group will receive instructions of sleep hygiene, limited use of screens and a relaxation audio. The occurrence of sleep bruxism will be assessed through a diary to be completed by the child's responsible party. A randomized, stratified sample of approximately 16 children will be included in the study. One group will be composed of 8 children with probable sleep bruxism who will receive the sleep hygiene intervention, and another group of children who will only receive instructions on sleep bruxism, with causes and consequences. Participants will be followed-up for 30 days. Parents will respond to a questionnaire about socioeconomic, demographic (child's age and gender), as well as parafunctional habits such as nail biting, biting objects, pacifier sucking, finger / thumb sucking and bottle feeding, child's sleep characteristics, screen habits, parental smoking, problems breathing, parental profession and also on psychological issues. Sleep habits will also be answered in this questionnaire, and parents will also answer the Strengths and Difficulties Questionnaire. The children over 6 years old will respond a Child Stress Scale and the Child of stressing sources in child; children less than 6 years will have the questionnaire responded by parents. The children will undergo a clinical examination to assess dental wear, according to the BEWE (Basic Erosive Wear Examination Index). The study evaluations consist of baseline, 1, 7, 15 and 30 days.
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
Hypotonia, particularly of the masticatory and oropharyngeal muscles, is one of the main characteristics of Down syndrome, resulting in impaired speech, chewing and swallowing. Moreover, the complete or partial obstruction of the airways during sleep may occur due to hypotonia of the tongue, leading to snoring and sleep disorders, such as obstructive apnea and sleep bruxism. Objectives: Analyze salivary levels of dopamine and cortisol and muscle activity before and after treatment with low-level laser therapy administered to acupoints in children with Down syndrome. Methods: A randomized, controlled, clinical trial will be conducted. Individuals four to 17 years of age with a diagnosis of Down syndrome and possible sleep bruxism will be screened at the Integrated Health Clinic of Nove de Julho University. We will evaluate orofacial dysfunction (NOT-S questionnaire), facial sensitivity, activity of the masticatory and trapezius muscles (electromyography), head posture as well as salivary cortisol and dopamine. After the evaluations, the participants will be randomized into two groups: Grupo 1 - treatment with low-level laser therapy at a wavelength of 808 nm; Group 2 - sham treatment (simulated laser therapy). Treatment will be conducted twice per week for a total of 12 sessions. The data will be tabulated and treated using GraphPad Prism version 7.0. The Kolmogorov-Smirnov test will be used to determine the normality of the data. Variables that fit the Gaussian curve will be expressed as mean and standard deviation. The t-test will be used for comparisons between the groups, with the significance level set to 5% (p <0.05).
The purpose of this study is to investigate the effects of mandibular occlusal stabilization splint (OSS) and modified farrar splint on sleep bruxism and respiratory indices and the effects of occlusal splints on the airway volume through imaging.
This cross-sectional study will evaluate the association between sociodemographic, occupational, clinical conditions, psychological (sense of coherence), sleep quality variables and SB diagnosed by PSG, the gold standard exam with audio-visual resources obtained at Pelotas Sleep Institute.
Background. Bruxism is an involuntary, non-functional activity of the masticatory system, and is frequently seen in childhood. Bruxism has many aetiologies, like malocclusion, psychological factors, allergies and gastrointestinal disorders. Aim. To investigate the relationship between Enterobius vermicularis infection and bruxism in children.
