Pain Perception of Needle-free System

"This study was performed among children aged 4-11 years who required dental treatment and were treated at the Department of Pedodontics, Faculty of Dentistry, Gaziosmanpasa University. A total of 70 patients were evaluated in accordance with the exclusion criteria and 56 children (31 girls and 25 boys) were included in this study. Children who needed dental treatment were randomly divided into two groups. All dental injections were administered by the same operator (MB), a pediatric dentist with two years of experience in using the Comfort-In system.~In both groups, the children were asked to rate their pain intensity by choosing the closest statement on the Wong-Baker Pain Scale at three time points: immediately after injection (Pain 1), during treatment (Pain 2), and at the end of the treatment (Pain 3)."
