AIMS: To develop a new approach to provide insights into contributing factors to the etiology and pathogenesis of temporomandibular disorders (TMDs) through discrimination of the salivary metabolomic profiling of patients with TMDs of muscular origin (ie, local myalgia) and healthy individuals. METHODS: Saliva samples from 19 patients with TMDs of muscular origin (ie, local myalgia) and 39 healthy controls were collected and identified by nuclear magnetic resonance (NMR) spectroscopy...

AIMS: To document National Dental Practice-Based Research Network (PBRN) practitioner treatment recommendations for patients with painful temporomandibular disorders (TMDs) and to identify practitioner/practice- and patient-related factors contributing to treatment recommendations made at the initial clinical visit. METHODS: This prospective single-sample cohort study formed groups based on treatment recommendations made by 185 dental practitioners who treated 1,901 patients with painful TMDs...

PURPOSE: To evaluate the prevalence of chronic widespread pain (CWP) and fibromyalgia syndrome (FMS) in TMD patients and the prevalence of TMDs in patients with FMS. METHOD: A systematic search was performed in electronic databases. Studies published in English examining the prevalence of comorbid TMDs and CWP/FMS were included. The Newcastle-Ottawa Scale was used to assess study quality, and meta-analyses using defined diagnostic criteria were conducted to generate pooled prevalence estimates...

AIMS: To assess changes in temporomandibular disorder (TMD) pain and multiple biobehavioral variables relevant to TMDs in response to an external stressor. METHODS: Self-reported data using online DC/TMD questionnaires were collected from volunteer dentistry graduate students. Data collection was performed on two occasions: during a non-exam period of the semester and during the subsequent exam period. Changes in the proportion of students with pain, differences in pain grade, and severity of biobehavioral status were measured and compared over the two periods...

AIMS: To describe the development of the Physical Symptom Scale-8 (PSS-8) and to examine its psychometric properties and use in temporomandibular disorder (TMD)-related assessment and research. METHODS: An online survey comprising demographic variables, the DC/TMD pain screener (TPS), Short-Form Fonseca Anamnestic Index (SFAI), PSS-8, PHQ-15, and Depression, Anxiety, and Stress Scale-21 (DASS-21) was administered to young adults attending a technical college. The PSS-8 adopted the Somatic Symptom Scale-8 (SSS-8) items but maintained the 3-point response scale and 4-week time frame of the PHQ-15...

AIMS: To measure brain activity in patients with bruxism and temporomandibular disorder (TMD)-related pain in comparison to controls using functional magnetic resonance imaging (fMRI) and to investigate whether modulations in jaw clenching led to different pain reports and/or changes in neural activity in motor and pain processing areas within and between both groups. METHODS: A total of 40 participants (21 patients with bruxism and TMD-related pain and 19 healthy controls) performed a tooth-clenching task while lying inside a 3T MRI scanner...

AIMS: To assess differences in biopsychosocial factors between participants with masticatory myofascial pain with referral (MFPwR), with myalgia without referral (Mw/oR), and community controls without TMDs. METHODS: Study participants were diagnosed with MFPwR (n = 196), Mw/oR (n = 299), or as a non-TMD community control (n = 87) by two calibrated examiners at each of three study sites. Pain chronicity, pain on palpation of masticatory muscle sites, and pressure pain thresholds (PPT) at 12 masticatory muscle, 2 trigeminal, and 2 nontrigeminal control sites were recorded...

AIMS: To identify the range of patient-reported outcome measures (PROMs) used in TMD studies, summarize the available evidence for their psychometric properties, and provide guidance for the selection of such measures. METHODS: A comprehensive search was conducted to retrieve articles published between 2009 and 2018 containing a patient-reported measure of the effects of TMDs. Three databases were searched: MEDLINE, Embase, and Web of Science. RESULTS: A total of 517 articles containing at least one PROM were included in the review, and 57 additional studies were also located describing the psychometric properties of some tools in a TMD population...

AIMS: To examine the effect of manual therapy applied to the cervical joint for reducing pain and improving mouth opening and jaw function in people with TMDs. METHODS: A systematic review of randomized controlled trials was performed. Participants were adults diagnosed with TMDs. The experimental intervention was manual therapy applied to the cervical joint compared to no intervention/placebo. Outcome data relating to orofacial pain intensity, pressure pain threshold (PPT), maximum mouth opening, and jaw function were extracted and combined in meta-analyses...

AIMS: To systematically review the literature assessing associations between TMDs and primary headaches. METHODS: Using validated clinical criteria, studies on TMDs and primary headaches published up to January 10, 2023 were identified using six electronic databases. This review adhered to the PRISMA 2020 guidelines and 27-item checklist and is registered on PROSPERO (CRD42021256391). Risk of bias was evaluated using the National Institutes of Health Quality Assessment Toolkits for Observational Cohort and Cross-Sectional Studies...

AIMS: To describe how some management practices in the field of orofacial musculoskeletal disorders (also described as temporomandibular disorders [TMDs]) are based on concepts about occlusal relationships, condyle positions, or functional guidance; for some patients, these procedures may be producing successful outcomes in terms of symptom reduction, but in many cases, they can be examples of unnecessary overtreatment. METHODS: The authors discuss the negative consequences of this type of overtreatment for both doctors and patients, as well as the impact on the dental profession itself...

This position statement was developed by an ad hoc committee of the American Academy of Oral and Maxillofacial Radiology and the American Academy of Orofacial Pain. The committee reviewed the pertinent literature and drafted recommendations for imaging. This joint statement provides evidence-based recommendations and clinical guidance for applying appropriate diagnostic imaging to evaluate the temporomandibular joint (TMJ). This manuscript guides the design of TMJ imaging examinations, addresses in-office CBCT imaging, and provides timely evidence-based recommendations to evaluate the TMJ bony components, also addressing the use of MRI and other modalities to evaluate TMJ involvement in different pathologic conditions...

Aims: To systematically review the qualitative evidence related to experiences of patients with temporomandibular disorders (TMD) and to explore their journeys within health care services. Methods: A systematic search of the following databases was conducted: MEDLINE, Embase, PsycINFO, Web of Science, CINAHL Complete, and the Cochrane database. Thematic synthesis was used to analyze and synthesize the data from qualitative studies that explored the journeys of TMD patients within health care services.
