Abstract
Aim: This study was carried out with the aim of comparing the efficacy of Transcutaneous electrical nerve stimulation (TENS) and 20% benzocaine gel prior to inferior alveolar nerve block (IANB) injections in alleviating pain in children of 8–12 years of age. Materials and Methods: The sample included fifty children in whom TENS application was done and fifty children in whom benzocaine topical application was done prior to administration of IANB injections for the extraction of mandibular posterior teeth. Pain perception was evaluated using Wong–Bakers Facial Pain Rating Scale in both the groups. ANOVA test was used to evaluate the differences in mean pain scores between the groups. Results: The patients demonstrated significant reduction in pain during IANB when TENS was used with a mean pain score of 3.36 as compared to topical application of local anesthetic agent with a mean pain score of 4.76, indicating higher efficacy of TENS. Conclusion: Application of TENS was more comfortable and significantly reduced pain. TENS is a safe, reliable, and practical alternative to be used in pediatric dentistry.
