Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Anxiety scale 1 - Modified Dental Anxiety Scale (MDAS)	The Modified Dental Anxiety Scale (MDAS) consists of 4 questions each with a 5 category rating scale, ranging from 'not anxious' to 'extremely anxious', hence, the total score varies from 4 to 20, with higher obtained scores describing more elevated levels of dental anxiety. MDAS is recorded before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure)/immediately after operation
Primary	Pain scale - Visual Analog Scale (VAS)	The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain." VAS is recorded before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure)/immediately after operation
Secondary	Anxiety scale 2 - State-Trait Anxiety Inventory for State Anxiety (STAI-S)	The STAI-S evaluates the subjective feelings of tension, worry, nervousness, apprehension, and autonomic nervous system activation. This self-completed inventory consisted of 20 items on a four-point Likert scale running from one (i.e., not at all) to four (i.e., very much). Hence, the total score varies from 20 to 80, with higher obtained scores describing more elevated levels of anxiety. STAI-S is recorded before and after operation,	5 minutes before operation/ immediately after operation
Secondary	Vital sign 1 - systolic blood pressure (SBP)	systolic blood pressure (SBP) is measured using a manual sphygmomanometer, before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure, and every 10min after)/immediately after operation
Secondary	Vital sign 2 - diastolic blood pressure (DBP)	diastolic blood pressure (DBP) is measured using a manual sphygmomanometer, before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure, and every 10min after)/immediately after operation
Secondary	Vital sign 3 - heart rate (HR)	Heart rate (HR)is measured as pulse rate using an oximeter, before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure, and every 10min after)/immediately after operation
Secondary	Vital sign 4 - oxygen saturation (SpO2)	oxygen saturation (SpO2)is measured using an oximeter, before, during and after operation.	5 minutes before operation/during operation (immediately after the most painful procedure, and every 10min after)/immediately after operation
