Filter by: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).
The aim of the study is to evaluate the complication rate of 2 types of all-ceramic crowns in patients with or without bruxism.
To determine the effectiveness of the Luco Hybrid OSA Appliance in the treatment of sleep bruxism and to aid in the treatment of associated tension/migraine type headaches in adults.
This study aims to evaluate, through a crossover, controlled, double-blind and randomized clinical trial, the efficacy of Phytolacca decandra in association or not with Melissa officinalis in the treatment of children with nocturnal bruxism. Children from 3 to 12 years old with nocturnal bruxism will be randomly allocated into different groups of treatment stage as follows: (1) placebo; (2) Phytolacca decandra; (3) Melissa officinalis; (4) Phytolacca decandra associated with Melissa officinalis. All children will participate to each clinical stage, with a period of 14 days of whashout. Children and the principal investigator will be masked to treatment. The efficacy will be evaluated through parents report about the absence of tooth clenching or grinding by children and electromiography exams. The secondary outcomes that will be evaluated are: trait anxiety and quality of life related to oral health.
Bruxism is a repetitive activity of the masticatory muscles characterized by grinding and/or clenching one's teeth or parafunctional movements of the mandible. The aim of the proposed controlled clinical trial is to evaluate muscle activity, bite force and salivary cortisol in children aged six to eight years with bruxism. The children will be randomly allocated to four groups, each with 19 participants: Group 1 will receive low-level laser therapy at acupuncture points; Group 2 will use an occlusal splint; Group 3 will receive placebo laser therapy; and Group 4 will be the control group without bruxism. Low-level laser (786.94 nm, 0.04 cm2, 70 mW and 20 s per points) will be applied directly on the skin at six acupuncture points on each side. The BTS TMJOINT electromyograph will be used to determine muscle activity and a digital gnathodynamometer will be used to measure bite force. Two saliva collections will be performed in the participant's home at 9 am and prior to going to sleep, with at least one hour of fasting and followed by oral hygiene with water. Evaluations will be performed before as well as one and six months after treatment. The findings will be computed and submitted to statistical analysis. Descriptive statistics will be used first for the determination of point estimates, precision and validation using analysis of variance (ANOVA) for the evaluation of residuals and parametric tests will be used for the determination of pre-treatment conditions. Interval estimates will be used for the variables of interest to determine the prevision of the estimates and perform comparisons. When necessary, transformation methods or non-parametric tests will be used in the data analysis. The chi-square test, Student's t-test and ANOVA will be employed, with the level of significance set at 5% (p < 0.05).
Excessive mechanical forces can cause complications of dental implants and their suprastructures (crowns and bridges), and can possibly be destructive for the bone and soft tissues around the implants. Sleep bruxism (grinding and clenching of the teeth during sleep) is considered as an important source of mechanical forces in the oral environment. Therefore, in this study, the investigators will investigate whether sleep bruxism is associated with implant and peri-implant complications.
Clinical trials of bite splint use and night time tooth grinding have not been performed. Consequently, there are no definitive outcome measures or efficacy standards that can be applied to large clinical trials. The present preliminary trial will determine what objective measures can be used to evaluate efficacy. The outcome variables will fall into four categories: (1) fabrication efficacy, (2) compliance, (3) functional efficacy, and (4) user satisfaction. The immediate goals will: (1) focus on the over-the counter SOVA night guard, (2) conduct tests under controlled clinical conditions using the 'gold standard', the acrylic 'bite splint' or 'orthotic', hereafter called the "Michigan bite splint", to compare the performance and efficacy of the SOVA night guard. Subsequent studies will be able to use the outcome variables identified in this study for broader clinical trials. Specific Aim 1. To compare the SOVA night guard to the custom-acrylic Michigan bite splint in clinical laboratory conditions. Hypothesis: There will be no significant differences between the devices in terms of fabrication efficacy, functional efficacy or user satisfaction. Specific Aim 2. To compare the SOVA night guard to the custom-acrylic Michigan bite splint under ecologically relevant conditions, i.e., the home environment. Hypothesis: There will be no significant differences between the devices in terms of compliance or functional efficacy.
The purpose of this study is to evaluate the effect of Botulinum toxin type A(Meditoxin®) on bruxism using polysomnography and determine which site is most appropriate for injection to obtain maximal effects.
Sleep bruxism (SB) is defined as a "stereotyped movement disorder characterized by grinding or clenching of the teeth during sleep" usually associated with sleep arousal. It might lead to abrasive tooth wear, hypermobility of teeth, tooth hypersensitivity, hypertrophy of the masticatory muscles and pain in the masticatory muscles. Diagnostic procedures include clinical evaluation, ambulatory monitoring sleep laboratory investigations and others. The clinical approach comprises the patient's history, orofacial examination, and tooth wear classification. There is no specific treatment for bruxism. Management of SB comprises psychological, orodental and pharmacological strategies.Orodental therapies, including soft vinyl mouth guards or stabilization bite splints, probably function more like protectors of the orofacial structures rather than actually diminishing bruxism.Drug treatment of sleep bruxism is controversial since different treatment strategies have resulted in suppression or exacerbation of this condition. Based on the current data, central primary efferents are the major drivers of bruxism. Therefore centrally acting agents such as antiepileptic drugs which also affect the sleep structure, might be effective on SB. In a case report of bruxism, anxiety and tremor, the authors suggested that anti-convulsant Gabapentine may be a useful treatment for patients with antidepressant-induced bruxism. However in the absence of definitive evidence, the appropiate treatment of SB is still a matter of debate. The objective of the present study was to compare the treatment efficacy of occlusal stabilization splint and Gabapentine on SB, using polysomnographically determined outcome measures for the quantification of sleep bruxism.
Objective: to evaluate the effects of physiotherapy on the anteroposterior airway size in a group of bruxist children Question: Is a physiotherapeutic technique aiming at changing the head posture, effective to increase the anteroposterior dimensions of the upper airway in bruxist children? Hypothesis: The bruxist children treated with physiotherapy will present higher airway dimensions Design: randomized clinical trial with allocation and blinding of the examiners. Participants: 3 to 6 year old children with complete primary dentition, dental and skeletal class I occlusion. The participants were classified as bruxist according to the minimal criteria of the ICSD for bruxism. The children were randomized in an experimental (n=13) and a control (n=13) group. Intervention: A physiotherapeutic intervention using the Awareness through movement technique was applied to the children of the experimental group once a week, until 10 sessions were completed. Outcome measures: anteroposterior measurements of the nasopharynx, oropharynx and hypopharynx taken in a lateral cephalogram with standardized techniques.
