Comparative Evaluation of Endo Ice® Refrigerant Spray, Endo Frost® Refrigerant Spray and Topical Anesthetic Agent Precaine B® on the Pain Perception in Children Prior to Administration of Local Anaesthesia – An Invivo Study

To compare and evaluate the efficacy of Endo Ice® refrigerant spray, Endo Frost® refrigerant spray and topical anaesthetic agent Precaine B® on the pain perception during local anaesthesia administration in pediatric dental patients.  Material and methods: A total of 87 participants in the age group of 6-12 years were divided into 3 groups randomly with 29 in each group. The cotton applicator sprayed with Endo Ice was held in contact with the buccal mucosa for 10 seconds. Immediately after the removal of the cotton applicator, inferior alveolar nerve block was administered. Similarly, Endo Frost was used on the participants. 0.1 mg of Precaine B was applied over the injection site contacting the buccal mucosa using sterile cotton applicator. FLACC evaluation was done by one trained personnel during the local anaesthesia administration. Following the local anesthesia, the participants were asked to rate their pain experience using VAS.  Results: The mean score of the Endo ice, Endo frost, and Precaine B were 4.3793, 4.4828 and 5.5517 respectively using the FLACC scale. The mean score of the Endo ice, Endo frost, and Precaine B were 4.2069, 4.2069 and 4.931 respectively using the VAS scale. Greater reduction in pain perception were observed in Endo Ice group followed by Endo Frost group and Precaine group. It was not statistically significant (p<0.005).  Conclusion: Endo ice, Endo frost and Precaine B were effective in reducing the pain perception in children, thereby reducing their fear and anxiety. Endo Ice group showed greater reduction in pain perception and higher efficacy than other groups, even though the results were not statististically significant.
