After administering a questionnaire to collect demographic data (including gender, age, education level, and frequency of dental visits) and MDAS scores, patients with an MDAS score of 10 or higher, indicating moderate to high dental anxiety, will be randomly allocated into three groups (n = 25 per group). Standard restorative treatment will be performed on the selected patients under music therapy.
A single carpule of local anesthetic without vasoconstrictor will be administered to each patient using a disposable dental syringe. Following anesthesia, caries removal and cavity preparation will be performed. The restorative procedure will then commence. All procedures will be performed by the same clinician following a standardized protocol. Selective enamel etching will be performed with phosphoric acid for 30 seconds, followed by rinsing and gentle drying. Universal dental adhesive will be applied and polymerized according to the manufacturer's instructions. Subsequently, the prepared cavities will be restored with a resin composite, which will be light-cured for 20 seconds using an LED curing unit. Upon completion of finishing and polishing, the total duration of the restorative procedure will be recorded. Only one restoration will be performed for each patient. Assessment of Physiological and Salivary Biomarkers In this study, systolic and diastolic blood pressure (SBP and DBP), oxygen saturation (SpO₂), heart rate (HR), salivary cortisol levels, salivary alpha-amylase (sAA) levels, and MDAS scores will be measured twice-once initially and once after the restorative procedure. Blood pressure will be recorded using a manual sphygmomanometer on the patients' right arms at heart level, and results will be expressed in mmHg. HR and SpO₂ will be measured with a finger-type portable pulse oximeter placed on the right index finger. Unstimulated saliva samples will be collected from each participant just before and immediately after the procedure. Patients will be instructed to expectorate into sterile disposable tubes, ensuring the samples are free of blood contamination. To control for circadian fluctuations in cortisol and sAA levels, all samples will be collected between 9:00 and 12:00 a.m. The collected samples will be immediately stored at -80 °C until analysis. A blinded researcher will perform all biochemical analyses after the completion of patient treatments. Samples will be thawed and centrifuged at 3,000 × g for 10 minutes. Cortisol concentrations will be determined using an enzyme-linked immunosorbent assay (ELISA) kit, while salivary alpha-amylase activity will be quantified with a colorimetric enzymatic assay. Absorbance values will be measured at a wavelength of 450 nm, and the results will be expressed in nanograms per milliliter (ng/ml) for cortisol and units for alpha-amylase.

RECRUITINGSystolic Blood Pressure (SBP)
Systolic blood pressure will be measured in a seated position using an automated sphygmomanometer. (Unit of Measure: mmHg)
Time frame: at baseline and immediately after the restorative treatment
Diastolic Blood Pressure (DBP)
Diastolic blood pressure will be measured in a seated position using an automated sphygmomanometer. (Unit of Measure: mmHg)
Time frame: at baseline and immediately after the restorative treatment
Oxygen Saturation (SpO₂)
Peripheral oxygen saturation will be assessed non-invasively using a finger pulse oximeter.
Time frame: at baseline and immediately after the restorative treatment
Heart Rate (HR)
Heart rate will be measured concurrently with blood pressure using an automated sphygmomanometer. (Unit of Measure: beats per minute (bpm))
Time frame: at baseline and immediately after the restorative treatment
Salivary Cortisol Levels
Salivary cortisol concentrations will be analyzed using an ELISA kit according to the manufacturer's protocol. (Unit of Measure: ng/mL)
Time frame: at baseline and immediately after the restorative treatment
Salivary Alpha-Amylase (sAA) Levels
Salivary alpha-amylase concentrations will be analyzed using an ELISA kit according to the manufacturer's protocol. (Unit of Measure: ng/mL)
Time frame: At baseline and immediately after the restorative treatment
Modified Dental Anxiety Scale (MDAS) Score
Anxiety levels will be assessed using the validated Modified Dental Anxiety Scale questionnaire. A 5-item anxiety scale; each item is rated 1-5 (Likert). The total score ranges from 5 to 25. Higher scores indicate greater dental anxiety (worse outcome). The outcome will be reported as change from baseline (Δ).
