The WAND (Computer-controlled local anesthesia) system provides anesthesia for children without fear of needles and quality and successful dental treatments can be performed as desired. The tip used in the device is too thin for the child patient to be noticed. In addition, since the handpiece in the form of a colored pencil resembles a magic stick compared to the classical injection form, it prevents the formation of fear in pediatric patients and increases its acceptability. Especially in pediatric patients with high anxiety, it is ensured that it is easy to work and all factors that may cause fear of the child are eliminated. Thus, the foundations of having a healthy mouth and teeth throughout their lives are successfully laid.
