Reduction of headache intensity and frequency with maxillary stabilization splint therapy in patients with temporomandibular disorders-headache comorbidity: a systematic review and meta-analysis.
This systematic review and meta-analysis aimed to analyze the effectiveness of maxillary stabilization splint (SS) therapy to reduce headache (HA) intensity and HA frequency in patients with temporomandibular disorders (TMD)-HA comorbidity. Randomized controlled trials (RCTs) using full-arch coverage, hard resin, and maxillary SS therapy were included. Electronic databases, including Cochrane Library, MEDLINE through PubMed, Web of Science, and EMBASE, were searched. The risk of bias was analyzed based on Cochrane's handbook. The search yielded 247 references up to January 28, 2020. Nine RCTs were included at a high risk of bias. The comparison groups included other splints, counseling, jaw exercises, medications, neurologic treatment, and occlusal equilibration. Four studies reported a statistically significant reduction in HA intensity, and five studies reported significant improvement in HA frequency from baseline at 2-12 months in patients with TMD-HA comorbidity treated with a full-arch hard maxillary SS. HA frequency in tension-type HA (TTH) comorbid with TMD diagnoses of myofascial pain (MFP) or capsulitis/synovitis improved significantly with SS than that with full-arch maxillary non-occluding splint (NOS) in two studies. Comparison groups receiving hard partial-arch maxillary splint nociceptive trigeminal inhibition (NTI) showed statistically significant improvements in HA intensity in patients with mixed TMD phenotypes of MFP and disc displacement comorbid with "general HA." Comparison groups receiving partial-arch maxillary resilient/soft splint (Relax) showed significant improvements in both HA intensity and frequency in patients with HA concomitant with MFP. The meta-analysis showed no statistically significant difference in the improvement of pain intensity at 2-3 months with comparison of the splints (partial-arch soft [Relax], hard [NTI], and full-arch NOS) or splint use compliance at 6-12 months with comparison of the splints (partial-arch Relax and full-arch NOS) versus the SS groups in patients with various TMD-HA comorbidities. In conclusion, although SS therapy showed a statistically significant decrease in HA intensity and HA frequency when reported, the evidence quality was low due to the high bias risk and small sample size. Therefore, further studies are required.

Meta-Analysis
Temporomandibular joint disorders (TMD) generate pain and difficulties for mouth opening affecting the patients' quality of life. Ozone is an emerging therapy that has been proposed as a potential treatment, due to that, the evidence about its efficacy should be reviewed. Therefore, this work aimed to conduct a comprehensive systematic review to address the efficacy of ozone therapy for the treatment of pain and limited mouth opening in patients with TMD. The design of the included studies was clinical trials and observational studies, whereas, a series of cases, in vivo, and in vitro studies were excluded. The search was performed in PubMed, ClinicalTrials, Web of Science, and Scopus. Gray literature was searched at Google Scholar. Relevant data of all included studies were recorded. The risk of bias (using RoB 2) and the quality (using Grading of Recommendations Assessment, Development, and Evaluation) assessments were carried out. Meta-analyses using random-effects models of pain and maximal mouth opening data were performed. This review included 8 studies with 404 participants suffering limited function and pain related to TMD. At the overall bias of the studies, 25% exhibited some concerns and 75% had high risk; and the quality of the studies was low. The analysis of the included studies suggests that ozone therapy can diminish pain and improve the maximal mouth opening in TMD patients. However, there is no conclusive evidence of ozone therapy as a superior treatment for TMD compared with occlusal splint and pharmacotherapy.

BACKGROUND
Bifid mandibular condyle (BMC) constitutes an extremely rare disorder characterized by a duplication of the head of the mandibular condyle. Its prevalence ranges from 0.31% to 1.82% in the published literature.
OBJECTIVES
The primary objective was to describe the main etiological, clinical and radiological characteristics of patients with BMCs and the existent treatment options. The secondary objective was to simultaneously include the characteristics of two new cases of BMC.
MATERIAL AND METHODS
An electronic search in Pubmed (MEDLINE), Scopus and The Cochrane Library was carried out by two independent reviewers until April 2018. Prospective or retrospective cohort studies, case series and case reports describing clinical and/or radiological characteristics of patients with BMC were included. Registered variables were demographic, etiological factors, diagnostic exam, clinical characteristics and treatment options. The results from the articles selected were organized in a Table along with the characteristics of two new cases of BMC provided by the authors.
RESULTS
From a total of 431 articles found in the initial search, 68 articles were finally included. This systematic review included 216 patients and 270 BMC with an average age of 30.6 (SD=14.7) years and a women:men ratio of 1.4:1. Mediolateral condylar orientation was the most prevalent position (80.1%). Among cases with known etiology, 40.8% of cases had a history of traumatism, while 55.9% did not present any relevant medical background. Half of the symptomatic cases had history of trauma. The most common symptoms were hypomobility (22.7%), arthralgia (18.1%), articular noise (17.2%) and ankylosis (17.6%). Active monitoring and manufacturing an occlusal splint were the most frequent treatment options.
CONCLUSIONS
BMC may have congenital or traumatic etiology. Hypomobility and arthralgia are the most frequent symptoms and treatment options are often conservative.

Review
Occurrence of Temporomandibular Disorders among patients undergoing treatment for Obstructive Sleep Apnoea Syndrome (OSAS) using Mandibular Advancement Device (MAD): A Systematic Review conducted according to PRISMA guidelines and the Cochrane handbook for systematic reviews of interventions.
BACKGROUND
Patients undergoing mandibular advancement device (MAD) therapy for obstructive sleep apnea (OSA) may experience changes in jaw position and altered occlusion. This could potentially contribute to the development or exacerbation of TMD symptoms. The literature on the long-term impact of MAD treated for OSA on TMD is scarce. Hence, this review was undertaken to ascertain the occurrence of TMD in MAD users.
METHODS
A comprehensive search protocol was implemented across several online databases using MeSH keywords and Boolean operators. A standardised data extraction form was developed specifically for this review. Two reviewers independently extracted the data. RoB-2 was used to evaluate the methodological quality of the included studies.
RESULTS
A total of 13 clinical studies were selected for this review. Some studies reported a significant reduction in the severity and frequency of TMD symptoms following MAD treatment. However, other studies did not observe significant changes in TMD symptoms or TMJ-related parameters from baseline to follow-up intervals. Temporary increases in TMJ-related pain or symptoms at the beginning of the follow-up period, which later subsided, were reported in some studies. Overall, MAD was not discontinued in any OSA patient due to TMDs.
CONCLUSION
The findings reveal that different outcomes associated with TMD are affected differently by MAD treatment for OSAS. According to a few studies, MAD therapy significantly reduced the severity and frequency of TMD symptoms. Other research, however, found no appreciable modifications in TMD symptoms or TMJ-related indicators. Although the overall results point to no significant effect of MAD treatment on TMD symptoms, the disparity in results between studies highlights the need for additional studies using standardised approaches.

Review
The most common temporomandibular disorders (TMD) signs and symptoms are related to muscle sensitivity through palpation, restricted mouth opening, asymmetric mandibular movements, joint sounds, pain and otologic signs and symptoms. To date, counselling, occlusal splints, exercises, biofeedback and acupuncture are examples of conservative modalities proposed for TMD therapy. The aim of this systematic review was to investigate the effect of these conservative therapies for TMD on otologic signs and symptoms. The authors searched the following electronic databases published up to 1st May 2015: PubMed, LILACS, Scopus, Web of Science and Science Direct with no time or language limitations. Using a two-phase selection process, the authors identified 08 articles and used them to conduct a qualitative analysis. Methodological quality of each article was performed with the aid of 'Quality Assessment of a Cohort Study' and 'Quality Assessment of a Randomized Clinical Trial', developed by the Dutch Cochrane Centre, a centre of the Cochrane Collaboration. This systematic review showed in seven of the eight studies included that a total or partial resolution of otologic complains occurred after counselling, exercise therapies and occlusal splint therapy. Upon the limitations of the studies included in this systematic review, the present outcomes suggested that there is insufficient evidence in favour or against the conservative therapies for TMD on changes in otologic signs and symptoms. Thus, further studies with a higher level of evidence and more representative samples should be conducted to better understand the relationship of TMD therapy changes on otologic complains.

Review
Idiopathic condylar resorption (ICR) is progressive resorption of the condyle of unknown aetiology. There is no consensus on the approaches for diagnostic imaging and management of this disease. The objective of this systematic review was to examine the best practices for imaging and to appraise the success of surgical and non-surgical therapy of ICR. Eleven search engines were queried via explicit literature searches for studies describing ICR, published until 2012. Two authors independently extracted data using predetermined characteristics. Studies that identified patients as having either ICR or progressive condylar resorption and that described the radiographic findings or treatment options were included. Seventeen studies contributing 178 cases met the eligibility criteria. The major radiographic findings, as assessed mostly by two-dimensional imaging, included decreased ramus height, decreased condylar height, altered volume of the condyle, decreased SNB angle and mandibular plane angle, and a retrognathic profile. Treatments included occlusal splints with orthodontic treatment, condylectomy with costochondral graft, and other surgical approaches. This systematic review was limited by the lack of meta-analysis. Nevertheless, we identified the need for future investigations: characterization of findings on three-dimensional imaging and its contribution to treatment planning, outcomes of non-surgical and pharmacological management of ICR, and randomized trials and comparative studies with longer follow-up periods.

Meta-Analysis
Purpose Temporomandibular disorders (TMDs) are frequent stomatological disorders. However, their treatment is controversial. Therefore, we compared the efficacy of combination therapy (splint therapy along with physiotherapy, manual therapy, and counseling) with physiotherapy, manual therapy, and counseling alone. The extent of mouth opening and pain perception were the outcomes.Study selection Systematic searches for English publications were performed using four major literature databases (Cochrane Library, EMBASE, PubMed, and Web of Science). We included randomized controlled trials. We calculated mean differences with 95% confidence interval (CI) for pain perception and maximum mouth opening (MMO) for the two groups. The Hartung-Knapp adjustment was used for cases comprising at least five studies.Results Six articles were included in the pain perception category, and four were reviewed for MMO at baseline. Four articles assessed pain perception, and two assessed MMO at 1 month. Five articles were analyzed upon comparing pain perception at baseline and 1-month follow-up. The mean difference was -2.54 [95% CI: -3.38; to -1.70] in the intervention group and -2.33 [95% CI: -4.06; to -0.61] in the control group. Two articles were analyzed upon comparing MMO at baseline and 1-month follow-up. The mean difference in the intervention group was 3.69 [95% CI: -0.34; 7.72], whereas that in the control group was 3.62 [95% CI: -3.43; 10.67].Conclusions Both therapies can be used in the management of myogenic TMD. Due to the marginal differences between the baseline and 1-month values, our results could not confirm the efficacy of combination therapy.

Meta-Analysis Review
The aim of this systematic review and network meta-analysis was to comprehensively evaluate and compare the effectiveness of diverse therapies for disc displacement (DD) of the temporomandibular joint (TMJ). An electronic search of PubMed, Embase, the Cochrane Library, the China Academic Journals full-text database (CNKI), and Wanfang databases was performed to identify relevant studies available up to 31 July 2021. Study selection, data extraction, and quality assessment were performed for all included studies, while the outcomes of interest contained post-therapeutic maximum mouth opening and pain intensity. Interventions consisted of arthrocentesis, injections with diverse drugs, occlusal splints, or a combination of two to three of the above. Controls were regarded as oral analgesics, self-exercise, massage, or health instruction. Twenty-six studies appeared to meet the inclusion criteria and were subjected to further examination. Our data of the entire network showed that the most invasive therapies performed better than non-invasive therapies, while arthrocentesis + platelet-rich plasma injection and platelet-rich plasma injection in Grade I performed well in both mouth opening improvement and pain alleviation. Platelet-rich plasma injection is probably the best treatment overall for patients with DD owing to its anti-inflammatory, analgesic, and lubricating effects.

Review
The review focuses on the last decade of research regarding the use of various oral appliances (OAs) in the management of sleep bruxism (SB) in adults. Sixteen (n = 16) papers of 641 identified citations involving 398 participants were included in the review. Of them, seven were randomised controlled trials (RCTs), seven were uncontrolled before-after studies and two were crossover trials. Analysis of the included articles revealed a high variability of study designs and findings. Generally, the risk of bias was low-to-unclear for RCTs and high for crossover studies, whilst the before-after studies exhibited several structural limitations. Nine studies used polysomnography/polygraphy/electromyography for SB diagnosis, whilst others were based on history taking and clinical examination. Most of them featured small samples and were short term. Of the studies using objective SB evaluations, eight showed positive results for almost every type of OA in reducing SB activity, with a higher decrease for devices that are designed to provide a certain extent of mandibular advancement. Among the studies using a subjective SB evaluation, one demonstrated a significant reduction in SB activity, and additional two showed a myorelaxant effect of OA in SB patients. Although many positive studies support the efficiency of OA treatment for SB, accepted evidence is insufficient to support its role in the long-term reduction of SB activity. Further studies with larger samples and sufficient treatment periods are needed to obtain more acknowledgements for clinical application.

Review
Stabilization splint is the treatment of choice for pain control in temporomandibular disorder (TMD) patients, even though its mechanism of action is still unknown. The aim of this systematic review is to provide a critical overview of the effectiveness of stabilization splint therapy on the basis of currently available literature data. The available Medline database was searched and 24 studies published since the 1995s have been consequently included in this review. The selection criteria were randomized controlled trials and clinical trials comparing splint therapy to either no treatment or another active treatment (physiotherapy, relaxation and drugs). Studies were grouped according to treatment type. Based on the currently best evidence available, it appears that stabilization splint has similar efficacy in controlling TMD symptoms as other active treatments (physiotherapy, relaxation and drugs). Stabilization splint therapy may be beneficial in reducing pain at rest and on palpation when compared with non-occluding splint. During a short period, education was slightly more effective than occlusal splint in treating spontaneous muscle pain. These two treatments did not have significantly different effects on pain-free mouth opening and pain during chewing. This review has shown evidence that most TMD patients are helped by incorporation of a stabilization splint. There is not enough data on the long-term efficacy and effectiveness of this widely used therapeutic tool. In the future, there is a need for well-conducted randomized controlled trials paying attention to adequate sample size, blind outcome assessment, duration of follow up, and using standardized methods for measuring treatment outcomes.
