Conditions

Jet Injection, Local Anasthesia

Brief summary

Pain during administration of local anesthesia remains one of the major concerns in dental practice, often leading to anxiety and treatment avoidance. Conventional syringe infiltration, while effective, is associated with discomfort during needle insertion and injection. This study aimed to evaluate the effectiveness, patient comfort, and clinical applicability of jet injection as a needle-free alternative for maxillary tooth extractions. A total of 80 adult patients were enrolled from the College of Dentistry, University of Baghdad, and Al-Amiriya Specialized Center for Dentistry between December 2024 and March 2025. Jet injection with 2% lidocaine and 1:100,000 epinephrine was delivered buccally and palatally using the Comfort-In system, and patient responses were assessed through a visual analog scale and Likert-based subjective feedback.
