Oral Anesthetic. Where Do I Put It

Hello, dental anesthesia, depending on the situation is different, have nerve block anesthesia (inject anesthetic to the nerve trunk, nerve plexus block pain) are infiltrating anesthesia (injected the anesthetic into submucosal periosteum or periodontal membrane, such as blocking nerve endings) with surface anesthesia (wet cotton wet apply with anesthesia drugs, the drug absorption), etc

Nerve block anesthesia and oral injection method and oral injection method. It depends on the situation. For example, the extraoral method of maxillary nerve block anesthesia is to enter the needle from the lower margin of the zygomatic arch, the midpoint of the sigmoid notch, and use a long needle to penetrate deep into the round foramen for deep injection, while the intraoral method of maxillary nerve block anesthesia is to Pierce into the great palatine foramen with a slender needle. (However, this type of external oral deep injection anesthesia method is rarely used now, because of the high risk, about 15% failure rate and deep injection, if not properly sterilized will cause deep infection, causing serious consequences. This type of injection is usually only used during major stomatological surgery.)
