ABSTRACT:
A method of administering an injectable anesthetic to the palatal tissue covering one of the foramina of the palate with a hypodermic syringe and a specialized instrument. The instrument has a handle with stem ends, the right hand end and left hand stem end each having a compositely angled shank part connected to a ring to be disposed flatwise on the palatal tissue. The ring at each end presents a blunted bottom to the palatal tissue. The ring further has a through slit therein. Firstly the instrument is placed in the patient's mouth with one of the rings in contact with the palatal tissue immediately adjacent to one of the foramina. The ring is firmly pressed against the palatal tissue until the tissue blanches and a pressure anesthesia through ischemia is achieved. Then a hypodermic syringe is placed in the mouth of the patient, and the needle is inserted through and guided by the ring into the very center of the palatal tissue. After that, the instrument is removed by passing the slit in the ring past the inserted needle, and then a liquid anesthetising drug is injected into the palatal tissue.
