Pain Perception During Administration Of Inferior Alveolar Nerve Block In Pediatric Patients: A Comparison Between Insulin Syringe And Conventional Syringe

Abstract

Background:

Pain during local anesthetic administration is a major concern in pediatric dentistry and is a key factor contributing to dental anxiety and uncooperative behavior in children. Conventional syringes, although effective, may increase discomfort and negatively affect the overall treatment experience.

Aim:

To compare pain perception during inferior alveolar nerve block (IANB) administration using a conventional dental syringe and an insulin syringe in pediatric patients.

Materials and Methods:

This study included 40 children aged 9–12 years who were visiting the dentist for the first time. The participants were divided into two groups: Group I received IANB using a conventional syringe, while Group II received anesthesia using an insulin syringe technique. Pain perception was assessed using the Wong-Baker Faces Pain Rating Scale and Visual Analog Scale (VAS). The collected data were statistically analyzed using mean and standard deviation.

Results & Discussion:

The insulin syringe group showed significantly lower pain scores (2.4 ± 1.5) compared to the conventional syringe group (7.7 ± 1.9). The reduced pain perception may be attributed to the smaller needle gauge and controlled delivery of anesthetic solution, resulting in decreased tissue trauma and improved patient comfort. These findings are consistent with previous studies supporting the use of finer needles in pediatric patients.

Conclusion:

Within the limitations of the study, insulin syringes were found to significantly reduce pain perception during local anesthetic administration compared to conventional syringes. Their use can improve patient comfort, cooperation, and overall dental experience, making them a viable alternative in pediatric dental practice
