Bruxism Assessment Section
Sleep and awake bruxism will be evaluated according to the bruxism diagnostic criteria established by the American Academy of Sleep Medicine (AASM) in 2023. Bruxism-related pain will be subjectively assessed using the Visual Analog Scale (VAS). The Visual Analogue Scale (VAS) is a 10-cm used to measure pain intensity, where 0 represents "no pain" and 10 represents the "worst imaginable pain. Patients mark their pain level, which is measured in cm or mm to determine the score.
Time frame: 6 months
Jaw Function Assessment Section
Jaw function will be evaluated using the Jaw Functional Limitation Scale-20 (JFLS-20). The Jaw Functional Limitation Scale-20 (JFLS-20) scores range from 0 to 200 (or 0-10 average per item), with higher scores indicating more severe jaw functional limitation. It measures 20 items across three constructs-mastication, vertical mobility, and verbal/emotional expression-using a 0-10 scale, with 0 meaning "no limitation" and 10 meaning "severe limitation
Time frame: 6 months
Pelvic Floor Assessment Section
Pelvic floor symptoms will be assessed using the Pelvic Floor Distress Inventory-20 (PFDI-20) and the relevant items of the Pelvic Pain Impact Questionnaire. The Pelvic Floor Distress Inventory-20 (PFDI-20) is a questionnaire measuring the severity of pelvic floor dysfunction, with total scores ranging from 0 to 300 (0 = no distress, 300 = maximum distress). It includes three subscales-POPDI-6, UDI-6, and CRADI-8-each scored from 0 to 100, calculated by multiplying the mean of answered items (0-4) by 25
Time frame: 6 months
Anxiety Assessment Section
Anxiety levels will be assessed using the State-Trait Anxiety Inventory (STAI - State Anxiety Scale). The State-Trait Anxiety Inventory (STAI-S) assesses temporary, immediate, or situation-specific anxiety using a 20-item self-report questionnaire with 4-point Likert-type responses. Scores range from 20 to 80, with higher scores indicating higher levels of anxiety. A cutoff of 39-40 is often used for detecting clinically significant symptoms.
