Investigation of Masseter and Temporalis Muscles Sections in Individuals With Temporomandibular Disorders

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to examine masseter and temporal muscle sections with Ultrasonography in this individuals depending on the origin of Temporomandibular Disorders.

Detailed Description
-----------------
Multidirectional evaluations are needed to examine the symptoms of Temporomandibular Disorders (TMD). Physical examination, questionnaires towards symptoms, and imaging techniques provide objective data on pathology. The chewing muscles should also be evaluated in this way and the approaches to be followed in subsequent processes should be determined. It is known that muscle sections are changed in TMD, which develops due to muscle disorders. However, regardless of the origin of TMD chewing muscles are affected depending on the condition.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Determination of the thickness of the masseter and temporalis muscles sections by Ultrasonography and the changes in the biomechanical properties of the masticatory muscles in individuals with temporomandibular disorders. | US has been described as an accurate and reliable imaging technique to assess the thickness and cross-sectional area of the chewing muscles and to determine changes in the local cross-sectional dimensions of the head and neck muscles in livings. It allows large-scale long-term studies of changes in the thickness of the jaw muscles during the development associated with changes in the biomechanical properties of the masticatory muscles. | Day 1 |
