Anesthetic in The Mouth. Where To Put It

Hello, oral anesthesia, according to different circumstances, there are nerve block anesthesia (injection of anesthetic into the nerve stem, nerve plexus, block pain conduction), infiltration anesthesia (injection of anesthetic into the submucosal periosteum or periodontal membrane, etc., block nerve endings), and surface anesthesia (wet application of cotton soaked with anesthetic drugs, so that anesthetic drugs can be absorbed)

Nerve block anesthesia also has the method of oral injection and oral injection. It depends on the situation. For example, the external method of maxillary nerve block anesthesia is to enter the needle from the lower margin of the zygomatic arch and the middle of the sigmoid notch, and use a long needle to Pierce the round hole deeply for deep injection, while the internal method of maxillary nerve block anesthesia is to Pierce the large palatal fora with a slender needle. (However, this type of oral deep injection anesthesia method is rarely used now, because the risk is large, about 15% failure rate and deep injection, if improper disinfection will cause deep infection, causing serious consequences. Generally, this injection method is only used in major stomatology surgery)

Infiltration anesthesia is administered in the mouth. Tissue was infiltrated with local anesthetics.
