Prevalence of Temporomandibular Disorders in Patients With Fibromyalgia Syndrome

Study Overview
=================
Brief Summary
-----------------
One Hundred Fifty woman patients diagnosed with fibromyalgia according to the American College of Rheumatology 2010 diagnostic criteria and 150 healthy woman volunteers will be included.Demographic data (age, gender, height, weight, marital status, education level) and duration of fibromyalgia diagnosis will be recorded. Patients will be evaluated according to the Diagnostic Criteria for Temporomandibular Disorders: Assessment Instruments (DCTMD: AI ). Patients will be evaluated by Diagnostic Criteria for Temporomandibular Disorders: Temporomandibular Disorders (TMD) Pain Screener, Symptom questionnaire, Clinical Examination Form from Assessment Instruments Axis I. Pain Drawing, Graded Chronic Pain (version 2), Jaw Functional Limitation Scale-8 (JFLS-8), Patient Health Questionnaire (PHQ-4), Oral Behaviors Checklist will be applied within the scope of Axis II.

Detailed Description
-----------------
In our study, the investigators aim to compare the frequency of temporomandibular disorders between healthy female participants and female patients diagnosed with fibromyalgia. Our study will consists of 300 female participants aged between 18 and 65 years who applied to the physical therapy and rehabilitation outpatient clinic between May 2021 and August 2021. This case-control study will conducted according to the Declaration of Helsinki. Participants gave written voluntary consent and enrolled in this case-control study. One Hundred Fifty woman patients diagnosed with fibromyalgia according to the American College of Rheumatology 2010 diagnostic criteria and 150 healthy woman volunteers will be included. Patients with temporomandibular region surgery, congenital teporomandibular joint pathologies, and previous temporomandibular region trauma were will be excluded from the study. Because fibromyalgia is a disease that mostly affects women, the investigators designed our study so that all participants were women. In addition, demographic data (age, gender, height, weight, marital status, education level) and duration of fibromyalgia diagnosis will be recorded. Patients will be evaluated according to the Diagnostic Criteria for Temporomandibular Disorders: Assessment Instruments ( DCTMD: AI ). Patients will be evaluated by Diagnostic Criteria for Temporomandibular Disorders: TMD Pain Screener, Symptom questionnaire, Clinical Examination Form from Assessment Instruments Axis I. Pain Drawing, Graded Chronic Pain (version 2), Jaw Functional Limitation Scale-8 (JFLS-8), Patient Health Questionnaire (PHQ-4),Oral Behaviors Checklist will be applied within the scope of Axis II.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| DCTMD: AI Axis I Pain Screener | TMD Pain Screener which is a simple, reliable, and valid self-report instrument used to assess for the presence of any pain-related TMD, with sensitivity and specificity ≥ 0.95 which is recommended for all patients in any clinical setting. A positive screen is followed by further evaluation to arrive at the specific TMD pain-related diagnoses. | 0 DAY | 
| DCTMD: AI Axis I Symptom questionnaire | Symptom questionnaire which assess pain characteristics as well as history of jaw noise, jaw locking, and headache. | 0 DAY | 
| DCTMD: AI Axis I Clinical Examination Form | Clinical Examination Form- The clinical examination includes provocation tests for TMJ arthralgia of pain with any jaw movement (ie, opening, lateral, and protrusive) and TMJ palpation. For myalgia, the tests include pain with opening jaw movements and palpation of the temporalis and masseter muscles. | 0 DAY | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| DCTMD: AI Axis II-Pain Drawing | Pain Drawing-pain drawing of the head, jaw, and body, and it allows the patient to report the location of all pain complaints | 0 DAY | 
| DCTMD: AI Axis II-Graded Chronic Pain (version 2) | Graded Chronic Pain (version 2) is a short, reliable, and valid instrument that assesses pain intensity and pain-related disability.10 The two GCPS subscales are: Characteristic Pain Intensity (CPI), which reliably measures pain intensity, with ≥ 50/100 considered high intensity, and the pain-disability rating, which is based on number of days that pain interferes with activity and on extent of interference with social, work, or usual daily activities | 0 DAY | 
| DCTMD: AI Axis II-Jaw Functional Limitation Scale-8 (JFLS-8) | Jaw Functional Limitation Scale-8 (JFLS-8) which assesses global limitations across mastication, jaw mobility, and verbal and emotional expression | 0 DAY | 
| DCTMD: AI Axis II-Patient Health Questionnaire (PHQ-4) | Patient Health Questionnaire (PHQ-4) is a short, reliable, and valid screening instrument for detecting psychological distress due to anxiety and/or depression in patients in any clinical setting.A cutoff of > 6, suggesting moderate psychological stress, should be interpreted as warranting observation, while a cutoff of > 9, suggesting severe psychological distress, should be interpreted as warranting either further assessment or referral | 0 DAY | 
| DCTMD: AI Axis II- Oral Behaviors Checklist (OBC) | Oral Behaviors Checklist (OBC), which assesses the frequency of oral parafunctional behaviors. | 0 DAY |
