Needle Bevel Type Affects Pain Perception in Children During Dental Anesthesia

Posted: September 2, 2025
A randomized controlled clinical trial examined the impact of needle bevel type on pain perception in children during inferior alveolar nerve block anesthesia. Sixty-six children aged 5-7 received injections with different needle bevels. The study found that the double scalpel blade bevel needle resulted in significantly lower pain scores compared to the conventional bevel needle. Objective and subjective pain assessments showed a clear advantage for the double scalpel blade bevel needle. Despite similar mechanical deformation, the double scalpel blade bevel needle demonstrated less injection pain during the procedure. This research highlights the importance of needle design in reducing pain perception during dental anesthesia in pediatric patients.
