Comparative Evaluation of Reduction in Pain Perception Using 5% Topical LA vs Freezed Cone as a Preparatory Agent for Intraoral Injection in Children and Effect of VRD as Distraction Technique

Abstract

Aim: To compare freezed cone and 5% lignocaine as a numbing agent before intraoral injection and evaluate the effect of virtual reality distraction (VRD) as a distraction technique in reducing pain perception in children.

Study design: Around 60 children of 6-11 years old undergoing treatment for the extraction or any pulp therapy of primary tooth were selected. Freezed cone and 5% lidocaine were used to decrease the pain during local anesthesia (LA). VRD was used as a distraction method and to analyze the pain perception, Wong-Baker Faces Pain Rating Scale was used.

Materials and methods: Each child was randomly assigned to receive ice as a topical anesthetic or lignocaine 5% as a topical anesthetic agent. The pain perception was evaluated after the injection of 2% lignocaine hydrochloride (HCL). The primary researcher evaluated the pain during injection using the sound, eye, motor (SEM) scale. The pain experienced during injection was evaluated using Wong-Baker Faces Pain Rating Scale.

Results: In the freezed cone group with the VRD technique, maximum responded to the less pain score. On the contrary, many responded to higher pain scores in the freezed cone group without the VRD technique.

Conclusion: It was concluded that the VRD technique can be used for distraction and the frozen ice cone can be an alternative method to reduce the pain perception during LA.
