Background: Whether pain, jaw function and quality of life are correlated with disc positions is controversial, and similar studies evaluating disc positions by magnetic resonance imaging (MRI) are very limited.
Objective: This study evaluated the pain, mandibular function and quality of life of the temporomandibular disorders (TMDs) patients with different disc positions according to MRI, and the relationship among them.
Methods: Three hundred and thirty-five participants were included.
Article Synopsis
- The study explored the connection between TMJ effusion and TMJ pain, as well as its impact on jaw function using both 2D and 3D MRI techniques.
- 121 patients with temporomandibular disorder (TMD) were examined, using MRI for effusion assessment, VAS for pain measurement, and JFLS-8 for jaw function evaluation.
- Findings indicated high agreement between 2D and 3D assessments for TMJ effusion; however, no significant links were found between effusion, pain, or jaw function limitations, while female patients showed a higher risk for TMJ effusion.
Article Synopsis
- The study aimed to examine how different types of disc displacement (DD) in Temporomandibular disorders (TMD) patients relate to the risk and severity of condylar erosion (CE) as seen in MRI and CBCT scans.
- The research involved 353 TMD patients, categorizing their DD and grading CE severity, using logistic regression to analyze data while accounting for variables like age and gender.
- Results showed that anterior displacement without reduction (ADDNR) significantly increased the risk and severity of CE compared to normal displacement, while anterior displacement with reduction (ADDR) was mostly linked to mild CE, particularly affecting females more.
Purpose: To evaluate head and cervical posture in individuals with or without temporomandibular disorders (TMDs) and to assess the correlations between pain, severity of symptoms, and posture.
Methods: A total of 384 patients (129 males and 255 females) was included. The Fonseca Anamnestic Index (FAI) was used to assess the severity and prevalence of TMD and the presence of temporomandibular joint (TMJ) pain.
Article Synopsis
- The study developed a new categorization scheme for temporomandibular disorders (TMDs) based on lateral cephalometric measurements from 501 adult patients.
- The researchers identified twelve principal components that explained over 91% of the variability in TMD profiles and uncovered three distinct subgroups through cluster analysis, focusing on different skeletal malocclusions.
- A decision tree model was created, achieving 85.4% prediction accuracy with eight key morphological indicators, aiming to enhance TMD understanding and treatment management.
Background: Degenerative joint disease (DJD) can be associated with disc displacement (DD) in temporomandibular disorder (TMD) patients. However, the relationship between different types of DDs and DJD remains unclear.
Objectives: To investigate the odds ratios of different types of sagittal and coronal DDs confirmed by magnetic resonance imaging (MRI) and DJD confirmed by cone-beam computed tomography (CBCT) in TMD patients.
Article Synopsis
- The study investigates how craniomaxillofacial features relate to psychological distress in adult orthodontic patients, focusing on a sample of 190 individuals divided by their Kessler psychological distress scores.
- Males with higher psychological distress displayed specific facial characteristics such as increased anterior facial height, altered lip length, and smaller overbite, while no significant differences were found in females.
- The findings suggest that orthodontists should consider the possibility of psychological distress in patients who exhibit certain craniomaxillofacial traits, such as a hyperdivergent facial pattern or open bite.
