Abstract
ABSTRACTTopical anesthesia is widely advocated in pediatric dentistry practice to reduce pain and anxiety produced by administration of local anesthesia. Cryoanesthesia to lessen the injection pain has also been reported to be promising. However, sparse literature reports exist regarding clinical efficacy of these agents.Aim: The purpose of this study was to compare the efficacy of the refrigerant (1,1,1,3,3-pentafluoropropane/1,1,1,2-tetrafluo-roethane), benzocaine and ice on the pain perception during intraoral injection using visual analog scale (VAS) and sound, eye, motor (SEM) scale.Study design: In this Spit-mouth design study, a total of 160 patients between the age group of 5 and 8 years were selected and were randomly divided into two equal groups having 80 patients in each group.Results: Ice cone has shown lower mean scores (p < 0.001) as compared to benzocaine and refrigerant whereas no significant difference was observed between refrigerant and benzocaine (p > 0.05) on both the scales.Conclusion: Ice cone had shown significantly higher efficacy as compared to benzocaine and refrigerant.How to cite this article: Lathwal G, Pandit IK, Gugnani N, Gupta M.

Highlights
Local anesthesia is required in any dental practice including pedodontics to alleviate the pain of dental procedures like extractions, pulpotomies, root canal treatments/ pulpectomies, drainage of abscesses and minor oral surgical procedures
The irony of the situation is that local anesthetics which are the most effective drugs for the prevention and management of pain[1] are themselves associated with pain and this pain gets further aggravated due to the fear and anxiety caused by the sight of the needle and has been referred to as needle phobia or blenophobia.[2]
The most widely advocated technique to minimize the pain of local anesthesia is the use of topical anesthetic agent before injection
Summary
Local anesthesia is required in any dental practice including pedodontics to alleviate the pain of dental procedures like extractions, pulpotomies, root canal treatments/ pulpectomies, drainage of abscesses and minor oral surgical procedures. The most widely advocated technique to minimize the pain of local anesthesia is the use of topical anesthetic agent before injection. Benzocaine due to its prolonged effect and acceptable taste is the most popular topical anesthetic agent used in dentistry. Cryoanesthesia is the application of cold to a localized part of the body in order to block the local nerve conduction of painful impulses. It may be induced either by the use of refrigerant sprays or with the use of ice. The focal application of ice before and sometimes after painful procedures has been practiced for thousands of years and was one of the first source of local anesthesia and analgesia
