Bruxism, Lifestyle, Anxiety, and Sleep Impairment in Dental Students.

The aim of this study was to verify the correlation of self-reported sleep and awake bruxism with demographic characteristics, oral behaviors, anxiety, temporomandibular disorder (TMD) signs and symptoms, sleep quality, and orthodontic treatment history in dental students. A total of 104 students of Dentistry located in Paraná (South Brazilian State) answered the following self-administered questionnaires: Oral Behavior Checklist, State Anxiety Inventory, TMD signs and symptoms questionnaire, and the Pittsburgh Sleep Quality Index. Associations between possible awake bruxism (AB) and sleep bruxism (SB) with sleep quality, anxiety, and TMD were analyzed by Poisson Regression with robust variance.

Phenotyping of somatosensory tinnitus and its associations: An observational cross-sectional study.

Background: Somatosensory tinnitus (ST) is associated with activation of the auditory pathway by trigeminal or cervical afferents.

Objective: This is a cross-sectional observational study that aims to verify the association of ST with TMD, bruxism, migraine and psychosocial aspects.

Methods: This study was conducted at the Tinnitus Outpatient Clinic of the Clinical Hospital Complex of the Federal University of Paraná.

Comparative analysis of temporomandibular joint morphology in degenerative joint disease: A cone-beam CT study in patients with and without arthralgia.

Unlabelled: This cross-sectional study aimed to compare, by using Cone-Beam Computed Tomography (CBCT), temporomandibular joint (TMJ) morphology among patients with degenerative joint disease (DJD) with or without arthralgia, as well as a control group.

Methods: Thirty-one patients and their respective CBCT TMJ exams were assessed. These individuals were selected from an Orofacial Pain Service and classified into three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): group 1 (10 patients with TMJ DJD and arthralgia), group 2 (11 patients with TMJ DJD without pain), and group 3 (the control group, consisting of 10 healthy individuals without any signs or symptoms of TMD).

Telediagnosis as an effective tool for assessment temporomandibular disorders.

Background: The use of communication technologies has allowed a substantial improvement in telediagnosis.

Objectives: To evaluate the feasibility and diagnostic agreement of synchronous teleconsultation compared to physical standard examination for temporomandibular disorders (TMD) and orofacial pain.

Methods: Sixty-one patients (50 women, 11 men) with a mean age of 46.

Childhood and Adolescents Sleep Bruxism Treatment: A Systematic Review.

 Sleep Bruxism (SB) is a common condition in childhood that can cause multiple consequences such as abnormal tooth wear, tensional headaches, masticatory muscle pain, or fatigue. The literature reports some interventions, however the treatment for SB in children is not well-established.  A systematic review was performed to investigate the effectiveness of the treatments described for SB in children and adolescents: pharmacological and psychological treatments; behavioral guidelines; and dental approaches.

Probable awake bruxism - prevalence and associated factors: a cross-sectional study.

Introduction: Bruxism is defined as a repetitive activity of masticatory muscles, characterized by the clenching or grinding of the teeth, which can occur during wakefulness (awake bruxism) or during sleep (sleep bruxism).

Objectives: The objectives of the present study were to determine the prevalence of awake bruxism and its associated factors.

Methods: Sample was composed by 50 participants of both genders, aged between 18 and 60 years, submitted to a clinical examination - to observe the presence of tooth wear, marks on the mucosa, or masseter muscles hypertrophy - and self-applied questionnaires, which evaluated the presence of TMD signs and symptoms, oral behaviors, lifestyles, anxiety level and sleep quality.

Interexaminer reliability for tomographic findings in temporomandibular joint degenerative disease and its agreement with clinical diagnosis: a blinded controlled cross sectional study.

Objectives: The aim of this study was to evaluate the interexaminer reliability for tomographic findings in degenerative temporomandibular joint disease and its agreement with clinical diagnosis.

Methods: Women aged 18 and 60 years were invited to participate in this research. All participants were evaluated by a single experienced examiner according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD).

Audiological Evaluation of Patients With Somatosensory Tinnitus Attributed to Temporomandibular Disorders.

Purpose Tinnitus and temporomandibular disorders have already been associated in the literature, but despite many studies, it is still an intriguing discussion point. This study aimed to evaluate the prevalence of hearing loss among somatosensory tinnitus patients with temporomandibular disorders and to assess the influence of tinnitus on patients' quality of life. Method An otolaryngologist examined 585 patients in order to detect and evaluate the presence of tinnitus.

Prevalence of Temporomandibular Disorders and Anxiety State Levels in Ballet Dancers A Cross-Sectional Study.

This study evaluated the prevalence of temporomandibular disorders (TMDs) in ballet dancers and explored their association with levels of anxiety. Participants were 51 male and female ballet dancers with a mean age of 31.5 ± 12.

Diagnostic validity of CT to assess degenerative temporomandibular joint disease: a systematic review.

Objectives: The aim of this systematic review was to answer the focus question: "In subjects with degenerative joint disease (DJD) of the temporomandibular joint (TMJ), what is the diagnostic validity of CT or cone-beam CT (CBCT) compared with clinical protocols"?

Methods: DJD should be assessed through clinical diagnosis according to RDC/TMD or DC/TMD. Search strategies were specifically developed to the following electronic databases: Cochrane, Latin American And Caribbean Health Sciences (LILACS), PubMed (including Medline), Scopus and Web of Science. Furthermore, partial grey literature search through Google Scholar, OpenGrey and ProQuest was performed.

Deep pain sensitivity is correlated with oral-health-related quality of life but not with prosthetic factors in complete denture wearers.

Low pressure Pain Threshold (PPT) is considered a risk factor for Temporomandibular Disorders (TMD) and is influenced by psychological variables. Objectives To correlate deep pain sensitivity of masticatory muscles with prosthetic factors and Oral-Health-Related Quality of Life (OHRQoL) in completely edentulous subjects. Material and Methods A total of 29 complete denture wearers were recruited.

Somatosensory evaluation in Dysfunctional Syndrome patients.

Many chronic pain patients are refractory to treatment, which leads to the suspicion that somehow they are not fully effective and probably some mechanism of pain generation and/or maintenance is still unknown. The aim of this cross-sectional study was to provide evidence-based data on pain mechanisms in different types of chronic pain conditions. Eighty women, with 18-65 years old, were included, divided into four groups: myofascial pain of the masticatory muscles (n = 20), fibromyalgia (n = 20), chronic daily headache and healthy volunteers (n = 20).
