Article Synopsis
  • The study aimed to evaluate which oral device, an occlusal splint (OS) or a mandibular advancement splint (MAS), provided better sleep quality and comfort for individuals with sleep bruxism (SB) and their relationship with reduced jaw muscle activity (RMMA).
  • Data from 21 subjects indicated that while the OS was slightly more comfortable and resulted in better self-reported sleep quality, the MAS was more effective in significantly reducing RMMA activity.
  • The findings suggest that comfort from the oral device impacts sleep quality in SB patients, but the MAS may be more effective for reducing bruxism-related muscle activity despite having slightly less comfort than the OS.

Dental sleep medicine as a discipline was first described about a quarter of a century ago. Snoring, obstructive sleep apnea, sleep bruxism, xerostomia, hypersalivation, gastroesophageal reflux disease, and orofacial pain were identified as dental sleep-related conditions. This scoping review aimed to: i) identify previously unidentified dental sleep-related conditions; and ii) identify the role of oral healthcare providers in the prevention, assessment, and management of dental sleep-related conditions in adults.

Article Synopsis
  • The study investigates the effects of oral appliances (OAs) on sleep bruxism (SB), focusing on heart rate variability (HRV) as a measure of autonomic nervous system activity during sleep.
  • A retrospective analysis of 21 participants indicates that using OAs significantly reduces rhythmic masticatory muscle activity (RMMA) during sleep but does not change HRV parameters.
  • The findings suggest that while OAs help mitigate the damaging effects of SB, their action does not directly affect the underlying mechanisms of SB.

Study Objectives: To examine the association between multiple measures of socioeconomic status (SES) and objectively measured obstructive sleep apnea (OSA) in a Canadian pediatric population.

Methods: This was a cross-sectional study of 188 children (4-17 years, mean age 9.3 ± 3.

Study Objectives: This study aims to assess whether the nocturnal wear of dentures has an effect on the quality of sleep and oral-health-related quality of life of the edentulous elderly with untreated sleep apnea.

Methods: A single-blind randomized cross-over design with two sequences and two periods was used. Participants (n = 77) were randomly assigned either to sequence 1 (nocturnal wear followed by nocturnal nonwear of the denture for 30-30 days) or sequence 2 (nocturnal nonwear followed by nocturnal wear of denture for 30-30 days).

Mandibular advancement device (MAD) therapy is the most commonly used non-continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA). Although OSA patients prefer MAD over CPAP, on average over one third have minimal or no major reduction in OSA severity with MAD therapy. Improved understanding of responder characteristics (or "phenotypes") to MAD may facilitate more efficient use of limited medical resources and optimize treatment efficacy.

Purpose: The effect of nocturnal wear of denture on sleep quality and integrity is still not well understood. Therefore, this systematic review was conducted to provide evidence on this topic.

Methods: Electronic searches were conducted from 1964 up to September 2015, using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials.

A small maxilla and/or mandible may predispose children to sleep-disordered breathing, which is a continuum of severity from snoring to obstructive sleep apnea. Preliminary studies have suggested that orthodontic treatments, such as orthopedic mandibular advancement or rapid maxillary expansion, may be effective treatments. The aim is to investigate the efficacy of orthopedic mandibular advancement and/or rapid maxillary expansion in the treatment of pediatric obstructive sleep apnea.

Introduction: Obstructive sleep apnea syndrome (OSAS) is a frequent breathing disorder occurring during sleep that is characterized by recurrent hypoxic episodes and sleep fragmentation. It remains unclear whether OSAS leads to structural brain changes, and if so, in which brain regions. Brain region-specific gray and white matter volume (GMV and WMV) changes can be measured with voxel-based morphometry (VBM).

Objective: We aimed to compare rhythmic masticatory muscle activity typical of sleep bruxism and oromandibular myoclonus (OMM) during rapid eye movement (REM) sleep in patients with idiopathic REM sleep behavior disorder (iRBD) and in Parkinson disease (PD) patients with RBD (PD-RBD).

Methods: Sleep polygraphic data were collected from 9 age-matched controls and 28 patients (mean±standard error of the mean, 66.0±1.

Objectives: Sleep bruxism (SB) frequently is associated with other sleep disorders and pain concerns. Our study assesses the efficacy of a mandibular advancement appliance (MAA) for SB management in adolescents reporting snoring and headache (HA).

Methods: Sixteen adolescents (mean age, 14.

Aims: To investigate the hypothesis that the presence of transient morning masticatory muscle pain in young, healthy sleep bruxers (SBr) is associated with sex-related differences in sleep electroencephalographic (EEG) activity.

Methods: Data on morning masticatory muscle pain and sleep variables were obtained from visual analog scales and a second night of polysomnographic recordings. Nineteen normal control (CTRL) subjects were age- and sex-matched to 62 tooth-grinding SBr.

Introduction: Chronic snoring is considered abnormal in a pediatric population. This disorder is often attributed to enlarged tonsils and adenoids, but multiple anatomic obstructions should also be considered. Facial and dental morphometry associations with various sleep-disordered breathing symptoms were investigated at an orthodontic clinic.

Introduction: When both narrow maxilla and moderately enlarged tonsils are present in children with obstructive sleep apnea, the decision of which treatment to do first is unclear. A preliminary randomized study was done to perform a power analysis and determine the number of subjects necessary to have an appropriate response. Thirty-one children, 14 boys, diagnosed with OSA based on clinical symptoms and polysomnography (PSG) findings had presence of both narrow maxillary complex and enlarged tonsils.

Background: Patients with insomnia may present with mild and often unrecognized obstructive sleep apnea (OSA).

Objective: To evaluate both subjective and objective outcomes of patients with complaints of insomnia and mild OSA who receive surgical treatment for OSA versus behavioral treatment with cognitive behavioral therapy for insomnia (CBT-I).

Methods: Prospective study with crossover design of 30 patients with complaints of insomnia and mild OSA.

Study Objective: Rapid maxillary expansion and adenotonsillectomy are proven treatments of obstructive sleep apnea (OSA) in children. Our goal was to investigate whether rapid maxillary expansion should be offered as an alternative to surgery in select patients. In addition, if both therapies are required, the order in which to perform these interventions needs to be determined.

Background: Pre-eclampsia is a leading cause of maternal-fetal morbidity and mortality. Significant overlap exists between the risk factors for pre-eclampsia and sleep-disordered breathing. Nasal continuous positive airway pressure (CPAP) has been proposed as therapy for pre-eclampsia.

Purpose: Sleep bruxism (SB) is associated with temporomandibular pain, headaches, tooth wear, and disruption of the bed partner's sleep. The aim of this report was to compare SB treatments from various experimental studies to guide the selection of a treatment for a large sample size study.

Materials And Methods: After a literature search, randomized controlled studies of 7 pharmacologic treatments and 3 oral devices were included.
