Review
This systematic review aimed to update the management of sleep bruxism (SB) in adults, as diagnosed using polysomnography (PSG) and/or electromyography (EMG). Management methods covered were oral appliance therapy (OAT) with stabilization splints, cognitive-behavioral therapy (CBT), biofeedback therapy (BFT), and pharmacological therapy. A comprehensive search was conducted on MEDLINE, Cochrane Library, and Web of Science up to October 1st, 2021. Reference list searches and hand searches were also performed by an external organization. Two reviewers for each therapy independently performed article selection, data extraction, and risk of bias assessment. The reviewers resolved any disagreements concerning the assortment of the articles by discussion. Finally, 11, 3, 14, and 22 articles were selected for each therapy. The results suggested that OAT tended to reduce the number of SB events, although there was no significant difference compared to other types of splints, that the potential benefits of CBT were not well supported, and that BFT, rabeprazole, clonazepam, clonidine, and botulinum toxin type A injection showed significant reductions in specific SB parameters, although several side effects were reported. It can be concluded that more methodologically rigorous randomized large-sample long-term follow-up clinical trials are needed to clarify the efficacy and safety of management for SB.

Review
Treatment of obstructive sleep apnoea (OSA) in adults is evolving, as new therapies have been explored and introduced in clinical practice, while other approaches have been refined or reconsidered. In this European Respiratory Society (ERS) guideline on non-continuous positive airway pressure (CPAP) therapies for OSA, we present recommendations determined by a systematic review of the literature. It is an update of the 2011 ERS statement on non-CPAP therapies, advanced into a clinical guideline. A multidisciplinary group of experts, including pulmonary, surgical, dentistry and ear-nose-throat specialists, methodologists and patient representatives considered the most relevant clinical questions (for both clinicians and patients) relating to the management of OSA. Eight key clinical questions were generated and a systematic review was conducted to identify published randomised clinical trials that answered these questions. We used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to assess the quality of the evidence and the strength of recommendations. The resulting guideline addresses gastric bypass surgery, custom-made dual-block mandibular advancement devices, hypoglossal nerve stimulation, myofunctional therapy, maxillo-mandibular osteotomy, carbonic anhydrase inhibitors and positional therapy. These recommendations can be used to benchmark quality of care for people with OSA across Europe and to improve outcomes.

Meta-Analysis
BACKGROUND
This systematic review of the literature was to compare the effects of exercise therapy and occlusal splint therapy on pain and mobility in individuals with painful temporomandibular disorders (TMD).
METHODS
PubMed, Embase and the Cochrane Central Register of Controlled Trials were searched for English publications from database root to March 1, 2020. Search terms were [("temporomandibular joint disorders" or "temporomandibular disorders" or "craniomandibular disorders" or "orofacial pain" or "myofascial pain" or "myofascial pain" or "facial pain") AND (exercise or "physical therapy modalities" or physiotherapy or "exercise therapy") AND ("splints" or "occlusal splints" or "stabilization splint" or "occlusal appliance" or "occlusal splint therapy")]. We included randomized controlled trials that evaluated the effects of therapeutic exercise therapy and occlusal splint therapy, and were published in English. Trial quality was assessed with the Physiotherapy Evidence Database scale.
RESULTS
Six studies were included (498 patients: 251 occlusal splint therapy, 247 therapeutic exercise). The results revealed that exercise therapy was not superior to occlusal splint therapy for pain reduction in patients with painful TMD (P=0.08; weighted standardized mean difference -0.29; 95% CI, -0.62 to 0.04). The effectiveness of occlusal splint therapy and exercise therapy was found to be equivalent in the maximum mouth-opening range (P=0.51; weighted standardized mean difference 0.12; 95% CI, -0.24 to 0.48), right laterotrusion (P=0.99; weighted standardized mean difference -0.00; 95% CI, -0.31 to 0.31), left laterotrusion (P=0.32; weighted standardized mean difference 0.16; 95% CI, -0.16 to 0.48), and protrusion (P=0.77; weighted standardized mean difference 0.06; 95% CI, -0.32 to 0.43) for painful TMD patients.
CONCLUSIONS
Given the limitations of the study, the small number of studies included in the sub-analysis for pain relief and the maximum mouth-opening range, and the small overall standardized mean difference for pain relief and mandibular movement observed, no high-quality evidence was found to distinguish the clinical effectiveness between occlusal splint therapy and exercise therapy for painful TMD patients. It appears that more randomized controlled trials comparing the effects of exercise therapy and occlusal splint therapy need to be implemented.

BACKGROUND
Currently it has been shown that botulinum toxin is effective for a wide variety of medical conditions, and can be applied for therapeutic purposes as cosmetic. In recent years, there has been a growing trend in the use of this drug substance to control the muscular overactivity of bruxism. The objective of this study was the use of botulinum toxin type A (BTX-A) than traditional methods, by conducting a systematic review of randomized clinical trials (RCTs) published in the health sciences literature.
MATERIAL AND METHODS
An electronic search was made in the databases of the PubMed, Cochrane Library and Scopus data between March and October 2017, ECA, which will analyze the effect of botulinum toxin in the treatment of bruxism. We included studies of bruxist patients older than 18 years where BTX-A tests were performed on the masseter and / or temporal muscles and the control systems were injections of placebo (saline) or the use of traditional methods for the treatment of bruxism. such as occlusal splints, other medications or cognitive-behavioral therapy.
RESULTS
Of the 68 studies identified, 4 RCTs that fit our inclusion criteria were selected. These studies show that BTX-A injections can reduce the frequency of bruxism episodes, decrease pain levels and maximum occlusal force generated by this pathology, offer superior efficacy in the treatment of bruxism compared to control groups who were treated with placebo or with traditional methods for the treatment of bruxism.
CONCLUSION
Infiltrations with BTX-A are a safe and effective treatment for patients with bruxism, so its use is justified in daily clinical practice, especially in patients diagnosed with severe bruxism.

Review
OBJECTIVES
Bruxism is a commonly reported oral parafunctional activity characterised by excessive tooth grinding or clenching outside normal functional activity. The present systematic review aims to examine the available literature to determine the effectiveness of occlusal splints in the treatment of bruxism compared to no treatment and alternative treatment modalities.
DATA
Data extraction was undertaken in conjunction with quality of evidence assessment.
SOURCES
A literature search of the following databases was undertaken: MEDLINE via OVID, Pubmed (Medline), Cochrane Oral Health Group's Trials, The Cochrane Central Register of Controlled Trials and EMBASE.
STUDY SELECTION
Randomised Controlled Trials (RCT) and quasi-RCTs which met the inclusion criteria were selected for analysis. These included studies comparing occlusal splints to no treatment or other interventions.
RESULTS
Twenty-two studies were identified for review with fourteen meeting the inclusion criteria. Only a small number of studies were available in each comparison (one or two for some) all of which had a medium to high risk of bias.
CONCLUSIONS
There is insufficient evidence to determine whether occlusal splint therapy for the treatment of bruxism provides a benefit over no treatment, other oral appliances, TENS, behavioural or pharmacological therapy. Furthermore, there is a lack of studies in each comparison with many suffering from a high risk of bias. There is a need for further research in this area and improvement in trial quality.
CLINICAL SIGNIFICANCE STATEMENT
This systematic review aimed to determine the effectiveness of occlusal splints in the treatment of bruxism. It found there was insufficient evidence to recommend occlusal splint therapy over no treatment or other treatment modalities. This is relevant to dental clinicians who may provide such appliances and cautions them in treatment provision.

Meta-Analysis Review
Obstructive Sleep Apnea (OSA) is often treated with Mandibular Advancement Devices (MADs). It is unclear whether particular design features are superior to others in terms of OSA alleviation. In order to facilitate clinical decision-making, this systematic review summarizes the objective and subjective outcomes of different available MAD designs. Studies comparing different MAD designs in OSA treatment were searched. After screening 1887 titles and abstracts, 20 original RCTs and six cohort studies were included. 14 articles were systematically reviewed in a meta-analysis. The decrease in AHI was significantly different between some of the MAD designs. The clinical relevance of the observed differences was however limited. Monoblock appliances performed more favorable, compared to bilateral thrust (effect size:-0.37; CI:-1.81 to 0.07). Midline traction appliances performed more favorable, compared to other designs. Custom appliances performed more favorable, compared to thermoplastic appliances (effect size:0.86; CI:-0.62 to 2.35). Furthermore, there were no clinically relevant differences between MAD designs in reduction of ESS, compliance, preference, side effects, and cost effectiveness. With respect to the included trials, presently there is not one superior custom MAD design in OSA treatment regarding the effect on AHI reduction, ESS improvement, compliance, preference, side effects, cost effectiveness, and other disease-related outcomes. We confirm custom MAD designs perform superior to thermoplastic MAD designs.

Meta-Analysis
CLINICAL QUESTION
What is the comparative effectiveness of available therapies for chronic pain associated with temporomandibular disorders (TMD)?
CURRENT PRACTICE
TMD are the second most common musculoskeletal chronic pain disorder after low back pain, affecting 6-9% of adults globally. TMD are associated with pain affecting the jaw and associated structures and may present with headaches, earache, clicking, popping, or crackling sounds in the temporomandibular joint, and impaired mandibular function. Current clinical practice guidelines are largely consensus-based and provide inconsistent recommendations.
RECOMMENDATIONS
For patients living with chronic pain (≥3 months) associated with TMD, and compared with placebo or sham procedures, the guideline panel issued: (1) strong recommendations in favour of cognitive behavioural therapy (CBT) with or without biofeedback or relaxation therapy, therapist-assisted mobilisation, manual trigger point therapy, supervised postural exercise, supervised jaw exercise and stretching with or without manual trigger point therapy, and usual care (such as home exercises, stretching, reassurance, and education); (2) conditional recommendations in favour of manipulation, supervised jaw exercise with mobilisation, CBT with non-steroidal anti-inflammatory drugs (NSAIDS), manipulation with postural exercise, and acupuncture; (3) conditional recommendations against reversible occlusal splints (alone or in combination with other interventions), arthrocentesis (alone or in combination with other interventions), cartilage supplement with or without hyaluronic acid injection, low level laser therapy (alone or in combination with other interventions), transcutaneous electrical nerve stimulation, gabapentin, botulinum toxin injection, hyaluronic acid injection, relaxation therapy, trigger point injection, acetaminophen (with or without muscle relaxants or NSAIDS), topical capsaicin, biofeedback, corticosteroid injection (with or without NSAIDS), benzodiazepines, and β blockers; and (4) strong recommendations against irreversible oral splints, discectomy, and NSAIDS with opioids.
HOW THIS GUIDELINE WAS CREATED
An international guideline development panel including patients, clinicians with content expertise, and methodologists produced these recommendations in adherence with standards for trustworthy guidelines using the GRADE approach. The MAGIC Evidence Ecosystem Foundation (MAGIC) provided methodological support. The panel approached the formulation of recommendations from the perspective of patients, rather than a population or health system perspective.
THE EVIDENCE
Recommendations are informed by a linked systematic review and network meta-analysis summarising the current body of evidence for benefits and harms of conservative, pharmacologic, and invasive interventions for chronic pain secondary to TMD.
UNDERSTANDING THE RECOMMENDATION
These recommendations apply to patients living with chronic pain (≥3 months duration) associated with TMD as a group of conditions, and do not apply to the management of acute TMD pain. When considering management options, clinicians and patients should first consider strongly recommended interventions, then those conditionally recommended in favour, then conditionally against. In doing so, shared decision making is essential to ensure patients make choices that reflect their values and preference, availability of interventions, and what they may have already tried. Further research is warranted and may alter recommendations in the future.

Meta-Analysis
OBJECTIVE
This systematic review aimed to assess the efficacy of occlusal splints in the treatment of temporomandibular disorders (TMDs).
MATERIAL AND METHODS
This systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Four databases (Medline Pubmed, Web of Science, Embase and Scopus) were searched, the last search was conducted on April 2020. Randomised controlled trials (RCTs) employing the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) or Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) as diagnostic criteria and including occlusal splint as one of the experimental groups were included in the present study. The data from the included studies were extracted and assessed for risk of bias.
RESULTS
Eleven studies were included. The sample size ranged from 12 to 96 subjects. The male to female ratio was 0 to 25%. The mean length of follow-up was 4 months. Occlusal splint had a positive effect on mandibular movements in all included studies. Seven studies showed a positive effect of occlusal splint on chronic pain reduction and pain intensity, while two others showed improvement of temporomandibular joint clicking sounds and locking of the jaws. Moreover, improvements in mouth opening, depression, and anxiety symptoms, were reported in four studies.
CONCLUSIONS
An occlusal splint can be considered as a non-invasive treatment approach for patients with TMD, especially those with signs and symptoms of restriction of mandibular movement and pain. Moreover, the present findings highlighted an urgent need of a standardised consensus regarding the prognostic evaluation of TMD.

Meta-Analysis
The best treatment modality for the management of painful temporomandibular disorders of muscular origin (M-TMD) with predictable outcomes based on solid evidence is still not well defined. Thus, the aim of this network meta-analysis (NMA) was to identify the best treatment for adult patients with M-TMD. An electronic search was undertaken from the inception of each database to August 2018, to identify randomized clinical trials (RCTs), which are comparing two or more of the following treatment modalities in patients with M-TMD: counseling therapy; occlusal appliances; manual therapy; laser therapy; dry needling; intramuscular injection of local anesthesia (LA) or botulinum toxin-A (BTX-A); muscle relaxants; hypnosis/relaxation therapy; oxidative ozone therapy; and placebo or no treatment. Primary outcome variables were the reduction of pain and mechanical sensitivity. The secondary outcome was the maximal mouth opening (MMO). The quality of evidence was rated according to Cochrane's tool for assessing risk of bias. Standardized mean difference was used to analyze via frequentist network meta-analysis (NMA), using STATA software. 52 RCTs were included in this NMA. At the most follow up moments, manual therapy, counseling therapy, occlusal splints therapy, and needling using BTX-A or LA as well as dry needling significantly decreased post-treatment pain intensity in M-TMDs, when compared to placebo. At short term (≤5 months), the four highest-ranked treatments for post-treatment pain reduction were manual therapy (83.5%, low quality evidence), ozone therapy (75.7%, very low quality evidence),counseling therapy (71.2%, moderate quality), and occlusal appliances (71.7%,moderate quality evidence). When intermediate term (≥6 months)was considered, BTX-A (85.8%, very low quality evidence) , counseling therapy(80%, low quality evidence), occlusal appliances (62.8%, low quality evidence) and hypnosis (50.6%, very low quality evidence) were the four highest-ranked treatments. This NMA reveals that manual therapy can be considered the most effective treatment for M-TMD, followed by counseling treatment, intramuscular injection of LA, and occlusal appliances . However, considering the limitations of the studies included, and the scarce of strong evidence, the present findings should be interpreted cautiously.

Clinical Oral Investigations Dec 2023To systematically review studies on various occlusal splint materials and describe their mechanical and chemical properties. (Review)
Review
OBJECTIVE
To systematically review studies on various occlusal splint materials and describe their mechanical and chemical properties.
METHODS
MEDLINE (PubMed), Scopus, and Web of Science searches were conducted for in vitro studies focusing on occlusal splint materials. Two reviewers performed an assessment of the identified studies and data abstraction independently, and this was complimented by an additional hand search. The articles were limited to those in the English language that were published between January 1, 2012, and December 1, 2022.
RESULTS
The initial search yielded 405 search results of which 274 were selected for full-text review following abstract evaluation. 250 articles that did not meet the inclusion criteria were excluded, and the remaining 25 articles (with 1 article identified from the reference lists of included articles) providing mechanical and chemical values were used in this review. Poly methyl methacrylate (PMMA) -based occlusal splint materials showed the highest values in terms of hardness, wear resistance, flexural strength, flexural modulus, e-modulus, and fracture toughness. The material group with the highest water sorption and water solubility was 3D printed (PR) splint materials. In addition, the lowest degree of double bond conversion was also observed in this group of materials.
CONCLUSIONS
The outcome of this review suggests that mechanically and chemically acceptable properties can be attained with PMMA-based occlusal splint materials using both conventional and digital production methods. PR splint materials should not be considered as the primary choice for long-term treatments due to their low mechanical and chemical properties.
CLINICAL RELEVANCE
This review provides clinical recommendations for selecting the appropriate material and fabrication method for occlusal splints while taking the patients' needs and the materials´ mechanical and chemical properties into account.
