Efficacy and Pain Perception of a Comfort-in™ for Palatal Anesthesia in Pediatric Dental Patients: A Randomized Controlled Trial
Year: 2026
Type: article
Abstract: Background: Needle phobia is frequently observed in children, contributing to heightened dental anxiety, uncooperative behavior, and care avoidance. The sight or sensation of traditional anesthesia needles can provoke intense emotional responses, complicating pediatric pain management. This study assesses the Comfort-in™ needle-free jet injector as an alternative, aiming to enhance anesthetic delivery, patient comfort, and cooperation during pediatric dental procedures. Aim: To assess the effectiveness of the Comfort-in™ system in minimizing pain during local anesthesia (LA) administration in pediatric dental procedures. Materials and methods: either a conventional needle syringe (group I) or the Comfort-in™ jet injector (group II). Pulse rate, behavior, pain, and local anesthetic effectiveness were evaluated. Results: = 0.000 and 0.000, respectively); with a lower pulse rate seen with the jet injector group, suggesting that the child had lower anxiety with the jet injector group. Similar results were seen with other parameters such as time required, LA efficacy, Wong-Baker FACES pain rating scale, and modified behavior rating scale by Taddio et al. Conclusion: Considering the limitations of the present study, the Comfort-in™ system demonstrated effectiveness as a needle-free alternative for minimizing pain and anxiety in pediatric patients, while also significantly reducing the time required for LA administration.
