A comparative study on pain perception in children, after application of pre-cooled and plain topical anesthetic gel during needle insertion for local anesthetic administration- In-vivo trial

Abstract

Aim: Comparison of efficacy of Pre-cooled and plain 5% lidocaine topical gel on pain perception during needle insertion during LA administration in children. Methods: Thirty children requiring bilateral infiltration anaesthesia of the age 6-10 years were selected for this split mouth study. Each injection site was randomly allotted to the control and intervention groups. Pulse rate, blood pressure was evaluated before; during and after LA infiltration and pain perception was evaluated using Won bakers scale. Data was statistically analysed using independent t-test and Man Whitney-U test (p-value <0.05). Results: The results obtained with intervention group, during LA administration was statistically significant with respect to pulse rate, diastolic blood pressure and pain perception (p-value=0.001). Conclusion: Pain experienced after application of pre-cooled topical anesthetic gel before LA infiltration is less compared to plain topical gel.
