Study Purpose The purpose of this observational study is to determine the prevalence of temporomandibular dysfunction (TMD) in individuals diagnosed with Sjögren's syndrome and to examine the relationship between disease activity and TMD. The main question to be answered is: Is TMD more common in individuals with Sjögren's syndrome, and is there a relationship between disease activity and TMD? Method Participants diagnosed with Sjögren's syndrome will be evaluated. The prevalence and severity of TMD will be examined along with mouth opening, head posture, and oral health parameters.

Fonseca Anamnestic Index (FAI)
Assesses the severity of TMD. As the score increases, the TMD severity (none, mild, moderate, severe) worsens. (0-15: None, 20-45: Mild, 50-65: Moderate, 70-100: Severe)
Time frame: Evaluations started immediately after receiving ethics committee approval and will be completed within 6 months, which is the study period.
EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI)
Evaluates disease activity. A high score (5 and above) indicates high disease activity. (The higher the average score, the more severe the symptoms of fatigue, pain, and dryness.)
Time frame: Evaluations started immediately after receiving ethics committee approval and will be completed within 6 months, which is the study period.
Xerostomia Inventory
Measures the severity of dry mouth (xerostomia) symptoms. A higher score indicates more severe xerostomia symptoms.
Time frame: Evaluations started immediately after receiving ethics committee approval and will be completed within 6 months, which is the study period.
Oral Health-Related Quality of Life - UK Scale
Assesses oral health-related quality of life. An increase in score generally indicates a greater deterioration in quality of life (i.e., worse oral health impact).
Time frame: Evaluations started immediately after receiving ethics committee approval and will be completed within 6 months, which is the study period.
Visual Analog Scale (VAS) for Disease Involvement
Numerically evaluates the severity of specific symptoms like dry mouth, dry eyes, facial skin dryness, and lip dryness. As the score approaches 10, the severity of dryness reaches its highest level.
Time frame: Evaluations started immediately after receiving ethics committee approval and will be completed within 6 months, which is the study period.
