Comparing the pH Change of Local Anesthetic Solutions The buffered samples were prepared to a 9:1 ratio (local anesthetic to sodium bicarbonate) using the Onpharma mixing system and by hand mixing.

An anesthetic buffered to physiologic pH has less sting. 3. Neutral pH anesthetics cross the nerve membrane much quicker than acidified LA. 4.

Conversely, dental anesthetics (lidocaine, novcaine, etc.) function best in slightly basic environments.

The authors of this paper recommend that all dental local anesthetic injections using articaine Buffered lidocaine has been recently recommended for local anesthesia, as there is less pain on injection of the buffered solution. Reduced pain on injection of lidocaine and epinephrine buffered to a neutral pH was confirmed in 20 subjects (P less than .01).
