Comparing Two Distraction Techniques with Illumination Caps for Assessing Dental Anxiety in Pediatric Patients during Single-visit Pulpectomies Based on the Perfusion Index Parameter

based tools such as specialized caps and laser light, as well as audiovisual distraction (AVD) techniques, has been explored for their calming effects on patients during dental and medical interventions. 3eripheral perfusion index (PI) is a noninvasive measurement with the ratio of pulsatile and nonpulsatile photoplethysmography signals obtained from pulse oximetry.This noninvasive and easily applicable technique can be used before or after anesthesia to obtain information about the fluid status and vascular tone of the patients.
