The Clinical Effects of Myofascial Trigger Points in Disc Replacement With Reduction

Study Overview
=================
Brief Summary
-----------------
This is a prospective, and controlled trial. 60 participants with myofascial trigger points and disc displacement with reduction and 60 participants with disc displacement with reduction will be included in the study. These two groups will be compared for clinical findings, pain severity and limitation of the temporomadibular function.

Detailed Description
-----------------
This is a prospective, and controlled trial. 60 participants with myofascial trigger points and disc displacement with reduction and 60 participants with disc displacement with reduction will be included in the study. The participants' ages will be between 18-65 years of both genders. These two groups will be compared for clinical findings with DC/TMD Axis I- Symptom Questionnaire, pain levels in the last 1 month with DC/TMD Axis II-Graded Chronic Pain Scale, and limitation of the temporomadibular function with DC/TMD Axis II-Jaw Functional Limitation Scale-8.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| mouth opening distance | Maximal opening of mouth is described as the greatest distance between incisal edge of maxillary central incisor to the incisal edge of mandibular central incisor, when the mouth is opened as wide as possible painlessly or as the inter incisal distance plus the overbite. | 1 day | 
| bruxism | bruxism is a stereotyped movement disorder characterized by grinding or clenching of the teeth | 1 day | 
| limitation of the movement of the temporomandibular joint | limitation of the movement of the temporomandibular joint | 1 day | 
| temporomandibular joint noises | noises of the temporomandibular joint | 1 day | 
| locking of the temporomandibular joint | locking of the temporomandibular joint | 1 day | 
| Graded Chronic pain Scale v.2.0 | Version 2 of the GCPS includes, in addition to the 3 items for pain intensity and 4 items for function, one item for number of days of pain. | 1 day | 
| Jaw Functional Limitation Scale-8 | The JFLS was initially developed as an 8-item global scale for overall functional limitation of the masticatory system; based on the resultant items and supporting psychometric data, the instrument was re-developed in order to expand measured constructs to also include masticatory limitation, vertical mobility limitation, and verbal and non-verbal communication limitation. | 1 day |
