Colors, Can They Reduce the Dental Anxiety

The investigator's aim in this study was to evaluate the preoperative anxiety and pain felt during the operation due to exposure to green, red, and blue light. For this purpose, the participants will wear colored glasses before the operation. The investigator will evaluate the patient's anxiety change and the pain she/he feels during the procedure.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in the Anxiety Score	Patients complete the State-Trait Anxiety Inventory (STAI) while seated in the dental unit. Ten minutes after the glasses are worn, patients fill out the anxiety scale again. Changes in the scores are the primary outcome of the study. The scale range is 20-40. A lower score means better results.	1 minute after the participant sits the dental unit and 10 minutes after

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Intraoperative Pain Score	Measuring the pain felt by the patient after the operation with the help of the visual analog scale. The range of Scala is 0-10. A lower score means better results.	1 minutes after the surgery
Change in the salivary cortisol level	Measuring the salivary cortisol level one minute after the patient sits in the dental unit and after ten minutes. Changes in the levels are the secondary outcome of the study.	1 minute after the participant sits the dental unit and 10 minutes after
Change in the oxygen saturation	Saturation measurement is done from the fingertip using a pulse oximeter one minute after the patient sits in the dental unit and after ten minutes. Changes in the scores are the secondary outcome of the study. The average value is above %90.	1 minute after the participant sits the dental unit and 10 minutes after
Change in the pulsation	Pulsation was measured from the fingertip by a pulse oximeter one minute after the patient sat in the dental unit and after ten minutes. Changes in the scores are the secondary outcome of the study. The average value is between 65 and 75.	1 minute after the participant sits the dental unit and 10 minutes after
Change in the salivary alfa-amilase level	Measuring the salivary alfa-amylase level one minute after the patient sits in the dental unit and after ten minutes. Changes in the levels are the secondary outcome of the study.	1 minute after the participant sits the dental unit and 10 minutes after
