Brief summary
Myofascial pain is a regional muscle pain condition characterized by hard local areas and tender bands, known for the presence of trigger points in muscle tissue. The treatment is to eliminate the etiologic factor. Regular exercise is recommended to relieve the trigger points. Occlusal splints, considered the gold standard in the treatment of temporomandibular joint disorders, are used to manage and control symptoms. In this study, patients between the ages of 18-45 years who applied to Çukurova University Faculty of Dentistry, Department of Prosthodontics with the complaint of myofascial pain and scored above 40 on the central sensitization scale will be taken as a sample.
Detailed description
Patients scoring 40 and above on the CSI scale will be evaluated according to the Diagnostic Criteria - Diagnostic Criteria for Temporomandibular Disorders (DC-TMD) and four groups will be formed including the control group diagnosed with myofascial pain. Bilateral masseter and temporal muscle thicknesses of all participants will be measured and recorded with a Clarius L7 ( Vancouver, Canada) ultrasound device. The control group will be trained and asked to comply with the training until the study is completed. The participants in the first experimental group will use occlusal splints that are digitally designed by transferring the impressions taken with intraoral scanner (TRIOS5, 3Shape TRIOS A/S, Copenhagen, Denmark) to the exocad design program and printed on three-dimensional printers. Participants in the second experimental group will be given home-based exercise programs prepared by physical therapists. Participants in the third experimental group will use occlusal splints digitally designed by transferring the impressions taken with intraoral scans (TRIOS5, 3Shape TRIOS A/S, Copenhagen, Denmark) to the exocad design program and printed on three-dimensional printers and will be given home-based exercise programs prepared by physical therapists. Muscle thickness measurements will be repeated at week 2, week 4, week 8 of the treatments and pain report forms will be filled out. As of week 8, treatments will be terminated and patients will be called to the clinic for control visits at week 12 and muscle thickness measurements will be repeated and pain report forms will be filled.
Interventions
DEVICEStabilization splint
Measurements will be taken from the patients with intraoral scans, transferred to the design program and a stabilization splint will be digitally designed. The designed splint will be produced from 3D printers.
OTHERMuscle exercises
Muscle exercises prepared by physical therapists will be planned to relieve trigger points in the masticatory muscles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Muscle Thickness | Baseline, 2 weeks, 4 weeks, 8 weeks, 12 weeks | Bilateral masseter and temporal muscle thicknesses of the participants will be measured with an ultrasound device (Clarius L7, Vancouver, Canada) , muscle thickness differences will be evaluated and the time period in which the effectiveness of the treatments will be observed will be determined. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Graded chronic pain scale | Baseline, 4 weeks, 8 weeks, 12 weeks | A questionnaire (Graded Chronic Pain Scale -1 to 10 grades scale index-, will be used to assess changes in the amount and frequency of pain and its impact on daily life. |
