Abstract

Background: Administering local anesthesia by injection is still the most common method used in dentistry. However, there is a constant search for ways to avoid the invasive and often painful nature of the injection and find a more comfortable and pleasant means of achieving local anesthesia before dental procedures.
Aim: To evaluate the pain perception among a group of pediatric dental patients after using Jet injection (INJEX).
Materials & Methods: The present study was conducted on 58 teeth in 39 children; 24 boys and 15 girls. The children included in the study were requiring local anesthesia for various dental procedures. Topical anesthetic gel was used, and then anesthesia was administered using the INJEX needleless device. Face pain rating scale (FRS) was used to assess the child’s pain perception during performing different dental procedures.
Results: Statistical analysis revealed no statistically significant difference between pain scores with different treatment procedures. However, comparison between boys and girls revealed that boys showed statistically Significant higher pain score than girls during cavity preparation only. Conclusion: Local anesthesia using INJEX showed low pain perception during different dental procedures.
