These are common concerns of parents and friends who want to take their children to the dentist but are worried about the pain and suffering of their children during the dental visit. In fact, these are also the concerns of our pediatricians, we hope that through the anesthesia of the teeth after dental treatment to reduce the treatment of the teeth to bring the children’s upset, but also hope that the anesthesia itself does not increase the children’s pain, and to reduce the fear of injections to children. Therefore, today we introduce to you a new minimally invasive painless local anesthesia technology (STA system). STA oral painless local anesthesia technology is currently the most advanced computer-controlled local anesthesia technology. STA system uses a computer-controlled anesthetic drug delivery system to slowly, uniformly, lower than the patient’s pain threshold of the injection speed injection, so that the patient in a relaxed and painless state to complete the anesthesia process. In the traditional manual injection, even for experienced doctors, children will still have slight discomfort during the injection due to the high transmission pressure of the needle and the uneven flow rate of the hand-pushed anesthetic injection. In addition, the needle handle of STA system is a small light blue plastic stick as shown in the picture below, the needle is easy to hide, and it is not easy to cause children’s fear, and most of the children tend to cooperate with the anesthesia treatment more happily.
