THE ORGANS OF SPECIAL SENSE WITH DENTAL ANESTHESIA 603 Repeated punctures by the needle are to be avoided when possible,as two or more teeth can be injected by using a long needle andadvancing it in such a position that the area of injection can be madeto embrace several teeth (Fig. 251). For injections upon the palatine surface the needle is made to entermore nearly in the axis of the tooth (Figs. 252, 254), inserted backfrom the gum margin, and advanced to a subperiosteal position overthe root apex. In dealing with the upper molars, instead of makingthe injection as above, an injection can be made into the posterior pala-tine canal (regional anesthesia), this injection sufficing for all threemolars, as follows: On the lateroposterior surface of the tuber maxillare of the superiormaxilla are seen a varying number of foramina, the openings of the
