Unlabelled: The prevalence of temporomandibular disorder (TMD) in patients with (dentofacial deformities) DFD is high, indicating a multifaceted relationship between physical and psychosocial factors.

Objective: To identify clusters of patients with DFD based on variables related to TMD, psychological aspects, somatization, oral habits, and sleep.

Method: Ninety-two patients with DFD were evaluated before orthognathic surgery according to demographic data, facial profile, presence of painful TMD (DC/TMD), psychological aspects, oral habits, comorbidities, substance use, and sleep quality.

Auriculotemporal neuralgia overlapped with chronic orofacial myofascial pain: A case report of a challenging diagnosis.

Aim: Auriculotemporal neuralgia (AN) is a rare condition characterized by severe, stabbing, unilateral pain inadequately described in the literature. Often coexisting with other conditions sharing the same innervation, and this overlap complicates clinical interpretation, leading to diagnostic errors and inappropriate therapeutic choices. The absence of AN in headache and facial pain diagnostic criteria hampers access to crucial information for diagnostic reasoning.

Risk factors for temporomandibular disorders: a systematic review of cohort studies.

Objective: A systematic review was performed to synthesize and identify risk factors involved in TMD onset.

Study Design: Electronic searches were conducted in PubMed, Web of Science, Scopus, Embase, PsyInfo and Lilacs databases, as well as in three gray literature databases (Google Scholar, ProQuest and Open grey). The studies were blindly assessed by two reviewers and selected by a pre-defined eligibility criterion.

Association between obstructive sleep apnea and temporomandibular disorders: A meta-analysis.

Background: Obstructive sleep apnea (OSA) is a very common condition in patients with temporomandibular disorders (TMD). However, there is little evidence of a connection between them.

Objective: The aim of this systematic review and meta-analysis is to assess the association between OSA and TMD in adult population.

Benefits of the combination of digital and analogic tools as a strategy to control possible awake bruxism: A randomised clinical trial.

Background: Awake Bruxism (AB) management includes cognitive and behavioural changes. Digital and analogic tools can be used to remind the individual to control/avoid AB behaviours. However, no study addressed both tools together.

Secondary bruxism: A valid diagnosis or just a coincidental finding of additional masticatory muscle activity? A narrative review of literature.

Introduction: Bruxism is defined as a repetitive masticatory muscle activity that can manifest it upon awakening (awake bruxism-AB) or during sleep (sleep bruxism-SB). Some forms of both, AB and SB can be associated to many other coexistent factors, considered of risk for the initiation and maintenance of the bruxism. Although controversial, the term 'secondary bruxism' has frequently been used to label these cases.

Assessment of awake bruxism and oral mucosa indentation in adolescents.

Background: Oral mucosa indentations can be signs of awake bruxism (AB) in adults, but this association has not yet been verified in adolescents.

Objectives: To evaluate the frequency of AB in adolescents and determine whether there is an association between AB and oral mucosa indentation.

Methods: This study enrolled 66 high school students, mean age of 16.

Catastrophizing and Hypervigilance Influence Subjective Sleep Quality in Painful TMD Patients.

To determine sleep quality and associated factors in a group of patients with painful TMDs. The medical records of 80 patients with arthralgia and/or myofascial pain were reviewed and compared to a healthy control group. Data about sex, age, subjective pain, physical activity, social activity, subjective sleep quality (Pittsburgh Sleep Quality Index [PSQI]), pain vigilance (Pain Vigilance and Awareness Questionnaire [PVAQ]), and pain catastrophizing (Pain Catastrophizing Scale [PCS]) were collected.

Association of sleep quality and psychological aspects with reports of bruxism and TMD in Brazilian dentists during the COVID-19 pandemic.

Background: Dentists are exposed to contamination by SARS-CoV-2 due to dental interventions, leading to a state of alert and potential risk of negative impact in mental health and sleep quality, associated with Temporomandibular Disorder (TMD) and bruxism.

Objective: to evaluate the psychosocial status, sleep quality, symptoms of TMD, and bruxism in Brazilian dentists (DSs) during the COVID-19 pandemic.

Methodology: The sample (n=641 DSs) was divided into three groups (quarantined DSs; DSs in outpatient care; and frontline professionals), which answered an electronic form containing the TMD Pain Screening Questionnaire (Diagnostic Criteria for Temporomandibular Disorders - DC/TMD), the Pittsburgh Sleep Quality Index (PSQI), the Depression, Anxiety and Stress Scale (DASS-21), and the sleep and awake bruxism questionnaire.

Research routes on improved sleep bruxism metrics: Toward a standardised approach.

A recent report from the European Sleep Research Society's task force "Beyond AHI" discussed an issue that has been a long-term subject of debate - what are the best metrics for obstructive sleep apnoea (OSA) diagnosis and treatment outcome assessments? In a similar way, sleep bruxism (SB) metrics have also been a recurrent issue for >30 years and there is still uncertainty in dentistry regarding their optimisation and clinical relevance. SB can occur alone or with comorbidities such as OSA, gastroesophageal reflux disorder, insomnia, headache, orofacial pain, periodic limb movement, rapid eye movement behaviour disorder, and sleep epilepsy. Classically, the diagnosis of SB is based on the patient's dental and medical history and clinical manifestations; electromyography is used in research and for complex cases.

Pain complications of oral implants: Is that an issue?

The use of oral implants as a form of replacing missing teeth in partial or total edentulous patients is considered the gold standard in oral rehabilitation. Although considered a history of success in contemporary dentistry, surgical complications may occur, as excessive bleeding, damage to the adjacent teeth and mandibular fractures. Persistent pain and abnormal somatosensory responses after the surgery ordinary healing time are also potential problems and may lead to the development of a condition named posttraumatic trigeminal neuropathic pain (PTNP).

Wake-Up Headache Is Associated With Sleep Bruxism.

Objective: To investigate the relationship between the frequency of sleep bruxism and report of morning headaches, and associations with depression and/or anxiety.

Background: The association between sleep bruxism and headaches in the morning, and between these factors and affective disorders, has been examined in several investigations. Although headache is cited by the International Classification of Sleep Disorders as a symptom associated with sleep bruxism, only a small number of studies have investigated the association between the frequencies of headaches in the morning and bruxism.

The association of self-reported awake bruxism with anxiety, depression, pain threshold at pressure, pain vigilance, and quality of life in patients undergoing orthodontic treatment.

Introduction: This study aimed to evaluate whether the presence of awake bruxism was associated with temporomandibular dysfunction symptoms, pain threshold at pressure, pain vigilance, oral health-related quality of life (OHRQoL), and anxiety and depression symptoms in patients undergoing orthodontic treatment.

Methodology: This observational study followed patients who had started receiving orthodontic treatment for six months. The following variables were measured three times (at baseline, one month, and six months): pressure pain threshold (PPT) in the right and left masseter, anterior temporalis, and temporomandibular joint (TMJ), and right forearm; pain vigilance and awareness questionnaire; and shortened form of the oral health impact profile (OHIP-14).

Influence of skin cold sensation threshold in the occurrence of dental sensitivity during dental bleaching: a placebo controlled clinical trial.

This study verified the occurrence of dental sensitivity in patients submitted to a 35% hydrogen peroxide based product (Whiteness HP Maxx 35% - FGM), skin cold sensation threshold (SCST) and its influence on dental sensitivity. Sixty volunteers were divided into 4 groups (n = 15), according to SCST (low: GI and GIII, and high: GII and IV) and bleaching treatment (hydrogen peroxide: GI and GII, and placebo: GIII and GIV). SCST was determined in the inner forearm for 6 different times using a neurosensory analyzer, the TSA II (Medoc Advanced Medical Systems, Ramat Yishai, Northern District, Israel).

Association between signs and symptoms of bruxism and presence of tori: a systematic review.

Objective: This systematic review aims to answer the question: "Is there an association between any specific signs and symptoms of bruxism and the presence of tori?"

Material And Methods: Observational studies, which evaluated the association between signs and symptoms of bruxism and tori, were selected. Signs and symptoms of bruxism (such as teeth grinding, jaw clenching, abnormal tooth wear, facial muscle hypertrophy, pain, or fatigue) had to be determined by questionnaire or anamnesis and tori within clinical assessment. Search-strategies were developed for five databases, in addition to three gray literature's databases.

Pain from Dental Implant Placement, Inflammatory Pulpitis Pain, and Neuropathic Pain Present Different Somatosensory Profiles.

Aims: To address the two following questions: (1) What kind of somatosensory abnormalities may be characterized in patients receiving dental implants (IMP), in ongoing inflammatory dental pulpitis (IP) patients, and in neuropathic pain (atypical odontalgia [AO]) patients? and (2) What sort of sensory and neural changes may result from dental implant placement surgery and pulpectomy?

Methods: A total of 60 subjects were divided into three groups: the IMP (n = 20), IP (n = 20), and AO groups (n = 20). Quantitative sensory testing (QST) was performed preoperatively (baseline) for all three groups and postoperatively at 1 month and 3 months after dental implant placement or pulpectomy (in the IMP group and IP group, respectively). Statistical analyses were completed with one-way and two-way analysis of variance and z score transformations (α = 5%).
