Primary outcome measure(s)
Anxiety scale 1 - Modified Dental Anxiety Scale (MDAS) — 5 minutes before operation/during operation (immediately after the most painful procedure)/immediately after operation 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.
Pain scale - Visual Analog Scale (VAS) — 5 minutes before operation/during operation (immediately after the most painful procedure)/immediately after operation 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.
