Effects of 2% lidocaine with epinephrine (1:100,000) administered by the various local anesthetic techniques--i.e., infiltration, mandibular block, and intraseptal injection--on pulpal blood flow in dogs were determined using the 15 microns radioisotope-labeled microsphere injection method. The pulpal blood flow decreased significantly with all three techniques; however, the most drastic reduction occurred in the molar teeth with the intraseptal injection. When 2% lidocaine without epinephrine was used in the intraseptal injection, pulpal blood flow increased significantly.
采用15微米放射性同位素标记微球注射法，测定了通过不同局部麻醉技术（即浸润麻醉、下颌阻滞麻醉和牙髓间隔内注射）给予2%利多卡因加肾上腺素（1:100,000）对犬牙髓血流的影响。所有这三种技术均使牙髓血流显著降低；然而，牙髓间隔内注射时，磨牙的血流减少最为显著。当在牙髓间隔内注射中使用不含肾上腺素的2%利多卡因时，牙髓血流显著增加。
