Özet
Background Central sensitization (CS) in patients with fibromyalgia (FM) having temporomandibular dysfunctions (TMD) symptoms may be related to psychosomatic features such as psychological state, sleep quality, pain and jaw muscle thickness. Objective To examine the relationship between CS, psychosomatic features and masticatory muscle thickness in FM patients having TMD symptoms. Materials and methods Forty women with FM having TMD symptoms were included. Central Sensitization Inventory (CSI) for CS, Depression Anxiety Stress Scale-21 (DASS-21) for psychological status, Jenkins Sleep Scale (JSS) for sleep quality, Visual Analog Scale (VAS) for body pain intensity related to FM and pain intensity related to temporomandibular joint (TMJ), Fonseca Anamnestic Index (FAI) for TMD severity, Fibromyalgia Impact Questionnaire (FIQ) for health status were assessed. The thicknesses of masticatory muscles were measured using ultrasonography. Results There were positive medium correlations between CSI scores and DASS-21-Depression (r = 0.690), DASS-21-Stress (r = 0.683), FAI (r = 0.706) and FIQ (r = 0.774) scores ( P < 0.05). There were positive weak correlations between CSI scores and DASS-21-Anxiety (r = 0.581), JSS (r = 0.544), VASbody pain-activity (r = 0.429), VASTMJ pain-rest (r = 0.333) and VASTMJ pain-activity scores (r = 0.396) ( P < 0.05). There were negative weak correlations between CSI scores and masseter (r = −0.314), and temporalis muscle thickness (r = −0.506) ( P < 0.05). Conclusion FM patients with TMD had high CS. It was found that increased CS negatively affected psychological state, sleep, and disease severity. It was seen to decrease the thickness of masticatory muscles. It was showed that CS should be taken into consideration for understanding and management of FM patients with TMD within the framework of a holistic and multimodal approach.
