Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to explore the relationship between the position of the temporomandibular joint (TMJ) disc and key clinical outcomes in patients with temporomandibular disorders (TMD). TMD is a condition that can cause pain, difficulty in jaw movement, and reduced quality of life. The research examines how disc displacement, as seen on MRI scans, correlates with pain levels, jaw function, and overall well-being. By better understanding these connections, the study seeks to provide insights that could improve the diagnosis and management of TMD, enhancing patient care and outcomes. This observational study involves non-invasive clinical and imaging assessments of TMD patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This observational, cross-sectional study investigates the correlation between temporomandibular joint (TMJ) disc position and clinical outcomes in patients diagnosed with temporomandibular disorders (TMD). TMD encompasses conditions causing pain, jaw dysfunction, and diminished quality of life. The study evaluates disc displacement using magnetic resonance imaging (MRI) and measures clinical outcomes such as pain severity (Visual Analog Scale), functional limitations (Helkimo Index), and quality of life (Oral Health Impact Profile-14).

Participants include 100 individuals aged 18-65 with clinically confirmed TMD. Data collection involves clinical evaluations and MRI imaging to classify disc displacement into categories such as normal, with reduction, and without reduction. Statistical analyses, including correlation and regression, identify relationships between disc position and outcomes while accounting for confounding factors.

The findings aim to improve understanding of the pathophysiology of TMD and guide diagnostic and therapeutic strategies for better patient outcomes. The study adheres to ethical guidelines, ensuring informed consent and patient confidentiality.

Normal Disc Position

Participants with an anatomically correct TMJ disc position as observed on MRI.

No interventions assigned to this group

Disc Displacement with Reduction (DDwR)

Participants whose TMJ disc is displaced anteriorly at rest but returns to its normal position during mouth opening.

No interventions assigned to this group

Disc Displacement without Reduction (DDwoR)

Participants whose TMJ disc remains displaced and does not return to its normal position during mouth opening

No interventions assigned to this group
