Abstract

Aim: The aim was to assess the impact of needleless injection (comfort in jet) on pain perception and its influence on the nearby oral mucosa and soft tissue, in comparison to the traditional needle injection technique during local anesthesia administration in children undergoing dental extraction.
Methodology: A total of 60 children aged 6 to 8 undergo dental extraction for at least one tooth. These children were randomly divided into two equal groups: intervention (needleless injection) or control group (needle injection). The primary outcome was to assess the self- perception of pain during injection. While secondary outcomes were assessing the child behavior using modified venham picture test scale, anesthesia onset and duration, anesthesia action, and effectiveness of anesthesia (pain during extraction) by using the face pain scale reversed.
Results: Face pain scale revised were similar, despite the potential soft tissue reactions from needleless injection. Post-extraction anxiety levels were comparable, but children showed higher acceptance rates and shorter anesthesia durations and a faster onset with needleless injection. However, needleless injection led to higher anxiety levels during extraction differing significantly between the groups.
Conclusion: This study highlights the potential benefits and considerations associated with needleless injection in pediatric dental settings. While needleless injection showed advantages such as higher acceptance rates and quicker onset of anesthesia, it also presented challenges including soft tissue changes and increased anxiety levels. The findings underscore the need for further research and careful consideration of needleless injection techniques in pediatric dentistry.
