A Comparative Evaluation Of Pain Perception And Anxiety In Pediatric Patient During Local Anesthesia Administration Using Conventional Syringe, Buzzy System And Computerized Controlled Local Anesthesia Delivery System

Abstract

Background: The administration of local anesthesia in pediatric dentistry can evoke significant pain and anxiety, impacting treatment outcomes and patient cooperation. This study aimed to evaluate and compare the effectiveness of three anesthesia delivery systems— conventional syringe, Buzzy system, and computer-controlled local anesthetic delivery system (CCLADS)—in managing pain perception and anxiety in children.
Methods: A total of 39 pediatric patients were randomly assigned into three equal groups (n=13 each) based on the anesthetic technique used: conventional syringe, Buzzy system, and CCLADS. Pain perception was assessed using the Visual Analog Scale (VAS), while anxiety levels were measured pre- and post-procedure using the Modified Dental Anxiety Scale (MDAS). Physiological responses, including pulse rate and oxygen saturation (SpO₂), were monitored using a pulse oximeter.
Results: The CCLADS group exhibited the lowest VAS scores, indicating significantly reduced pain, followed by the Buzzy system. MDAS scores showed a marked reduction in anxiety post-treatment in the CCLADS group compared to the other two groups. Physiological parameters also reflected better stability in the CCLADS group.

Conclusion: The computer-controlled local anesthetic delivery system proved to be the most effective in minimizing pain and anxiety in pediatric dental patients, followed by the Buzzy system. Conventional syringe administration was associated with the highest discomfort and anxiety, highlighting the importance of adopting child-friendly anesthesia techniques in pediatric dentistry.
