The needle should be entered at a right angle to themucous surface, injecting as the needle is advanced, and slowlypushed through to the periosteum, which is penetrated, and theneedle advanced a short distance along the bone and well up towardthe root of the tooth; the opening in the needle point should alwaysbe directed toward the bony surface (Figs. 255, 258), the remainderof the solution now slowly injected, the needle withdrawn, and thefinger pressed upon the point of injection for a few seconds. In. Fig. 260.—Position of needle for injection at maxillar^^ tuberosity. (After Fischer.) those parts of the mouth in which the needle cannot be advancedat a right angle it must be done obliquely, but should be made asnearly at right angles as possible. Repeated punctures by the needle are to be avoided when pos-sible, as two or more teeth can be injected by using a long needleand advancing it in such a position that the area of injection canbe made to embrace several teeth (Fig. 256). For injections upon the palatine surface the needle is made toenter more nearly in the axis of the tooth (Figs. 257, 259), insertedback from the gum margin, and advanced to a subperiosteal posi-tion over the root apex. In dealing with the upper molars, insteadof making the injection as above, an injection can be made into theposterior dental canals (regional anesthesia), this injection sufficingfor all three mOlars, as follows: On the lateroposterior surface of the tuber maxillare of the 650 LOCAL ANESTHE
