Referred Pain Manifestation and Its Impact on Patients With Temporomandibular Disorder.

Objective: To investigate whether a higher number of sites eliciting referred pain upon palpation is associated with greater impairment in biopsychosocial aspects in TMD patients and identify variables that predict increased referred pain.

Methods: This cross-sectional study analyzed data from 77 women with myalgia, assessing the number of sites eliciting referred pain upon palpation in relation to clinical (duration, frequency, intensity, painful body sites, pain-related disability), psychological (stress, anxiety, depression, catastrophizing, sleep quality), and psychophysical variables (mechanical and pressure pain thresholds, temporal summation and conditioned pain modulation).

Results: Spearman's correlation revealed a significant correlation between the number of sites eliciting referred pain upon palpation in the orofacial region and both pain intensity and frequency (p < 0.

Interplay of Psychosocial, Clinical and Modulation Mechanisms in Chronic TMD-Related Disability.

Background: Temporomandibular disorder (TMD) is a multifactorial condition characterised by pain and functional impairment in the orofacial region. Although psychosocial and psychophysical factors significantly influence chronic pain, their combined impact on functional disability remains poorly understood.

Objectives: To investigate the influence of clinical, psychosocial and psychophysical variables on functional disability related to chronic pain in muscular TMD, utilising principal component analysis (PCA) and logistic regression.

Do Objective Sleep Metrics and Psychosocial Profiles Differ in the Presence of Possible Awake Bruxism in Patients With Obstructive Sleep Apnea? A Preliminary Polysomnographic Study.

Objective: Poor sleep quality and psychosocial impairment are reported to be important aetiological factors for the presence of awake bruxism (AB) although with its absence of certainty. Therefore, this preliminary study aimed to investigate the relation between polysomnography (PSG) objective sleep metrics and psychosocial factors in the presence of possible AB in obstructive sleep apnoea (OSA) individuals.

Methods: A cross-sectional study was conducted with 38 OSA individuals (47.

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.

Central sensitization inventory is associated with psychological functioning but not with psychophysical assessment of pain amplification.

Background: The central sensitization inventory (CSI) is a questionnaire that has been widely used as a tool for assessing symptoms associated with sensitization. However, its ability to identify individuals with this phenomenon has recently been questioned. The aim of this study was to assess the correlation of CSI with psychosocial and psychophysical factors in patients with painful TMD diagnosed according to diagnostic criteria for temporomandibular disorders (DC/TMD) and asymptomatic controls, as well as to determine the influence of these variables on the CSI scores variations.

Somatosensory alterations after single-unit dental implant immediate loading: A 1-year follow-up study.

Objective: This cohort study aimed to assess the incidence of somatosensory alterations after implant surgery using standardized quantitative and qualitative sensory testing.

Methods: 33 participants with single-tooth loss, undergoing immediate implant loading were included. Quantitative Sensory Testing (QST) and Qualitative Sensory Testing (QualST) were conducted at eight time points over a year (baseline to 1 year).

Influence of psychometric and sleep quality features on painful mechanical sensitivity and pain modulation in patients with temporomandibular disorders.

Unlabelled: Investigating the collective impact of psychometric properties and sleep quality on pain sensitivity in temporomandibular disorder (TMD) patients could improve clinical management strategies.

Objective: Assessing whether combined psychometric properties and sleep quality impact painful mechanical sensitivity and pain modulation in TMD patients.

Materials And Methods: A cross-sectional study using secondary data analysis of 77 TMD patients and 101 controls.

Assessment of temporomandibular joint bone changes associated with anterior disc displacement: An MRI cross-sectional study.

Objective: This cross-sectional study aimed to evaluate the presence of bone changes on magnetic resonance imaging (MRI) scans of patients with temporomandibular joint (TMJ) anterior disc displacement (ADD) with reduction (ADDWR) and without reduction (ADDWoR).

Methods: TMJ-MRI scans were screened for the presence of ADD. 285 scans presented ADD, being further divided into ADDWR (n = 188) and ADDWoR (n = 97).

Correlation between the presence of the median perforating canal in adults with sex, age and skeletal facial patterns: A cross-sectional study.

Introduction: The aim of the present study was to evaluate the presence of the median perforating canal (MPC) and its morphometric measurements in Cone Beam CT (CBCT) scans of adult patients, correlating the findings with sex, age and skeletal facial patterns.

Material And Methods: 717 CBCT scans were selected from a Brazilian population and the presence of the MPC was recorded. MPC diameter was measured in three points: lingual, medial and buccal.

Cone-beam computed tomographic study of the persistent foramen tympanicum according to age, sex, and skeletal patterns.

This cross-sectional study evaluated the influence of prevalence, laterality and diameter of persistent foramen tympanicum (PFT) in cone beam computed tomographic (CBCT) scans of adult patients with different sagittal skeletal patterns, sex and age. CBCT of 510 patients were assessed for the presence of PFT. Skeletal pattern, age and sex of the affected patients were recorded, as well as laterality and diameter of PFT.
