I'll give you a comparison. Look at the local consumption situation. It varies according to the difficulty of teeth. First of all, let's take a film. Within 50, there are more than a dozen pieces of local anesthesia and nerve block anesthesia 100. It's hard to say that there are at least 100 things when tooth extraction is carried out. . Root splitting plus jaw repair is less than 300, probably. This is the whole process. I calculated the details for you according to our side, but it still depends on your own hospital, but it should not be too different, about 500 to 700. Of course, if it is the legendary deep-buried transverse resistance, it is hard to say.
