Trust that by being able to come to you for a tooth extraction or other treatment, the client already trusts you a lot. But at this time, we should also emphasize that we are capable of doing the job well. The language is not necessarily much, it is just to give the guest a “shot in the arm”, such as: “This anesthetic is the best at present; this anesthetic is not painful at all; this needle is very small, basically nothing to feel; this is the most advanced in the world… …” sometimes give the impression of an unintentional sentence or even half a sentence, the guest will get the effect of a strong heart. 1.Distract the attention of dental guests. You can use a piece of the guest’s clothing or a piece of jewelry or a sentence as an entry point to draw his attention away. Never let the guest see your syringe. Repeatedly and repeatedly ask him to open his mouth so that he gets used to your instructions and cooperates. It is worth mentioning that the average guest resents the anesthetic when lying flat. 2, the first thing to do during the opening of the mouth is to apply surface anesthetic cream at the entry point, some directly with bupivacaine, which is also good. Then routine disinfection. 3, the temperature of the anesthetic. Warm water is heated about 50, reaching forty-two degrees when entering the syringe, and reaching more than 37 degrees when entering the body. This will allow the guest to have no discomfort. Otherwise, the cold heartburn of winter will make you a memory of his life. 4, needles try to use disposable dental needle, finer. If you have the conditions, even the syringe also use special. 5, into the needle point. Try to choose the mucosa, less gums. The tissue under the mucosa is loose, and the anesthetic is easy to penetrate. 6, fast stabbing. Once pierced, give 0.1 ml of drug. then slowly advance and give a small amount of drug while advancing (the syringe maintains proper pressure so that the anesthetic is always located in front of the needle). When injecting, be sure to maintain a constant speed and give the drug slowly (the injection rate in the hard palate area, usually 1~2ml per minute, is very slow and slow). Here to show the doctor’s patience, nothing to look at the table, a minute is how long? While injecting to speak some words that can distract the guests, so that they feel relaxed (usually say the accustomed, without thinking should say a lot of appropriate words to). After the injection, you can say something to ease the atmosphere, or even have the nurse rinse his mouth several times, so that the guest can feel that everyone is serving him and get a kind of satisfaction. In short, it should not be ignored.
