Measure
All Study Participants
Patients will be randomized to one side of the mouth getting the buffered anesthetic and the other side of the mouth to the non-buffered anesthetic. Non-buffered Anesthetic: non-buffered LA, 2% lidocaine with epinephrine 1:100,000 Buffered Anesthetic: A cartridge of 2% lidocaine with epinephrine 1:100,000 alkalinized at 9:1 ratio with a resulting pH of 7.21 using 8.4% sodium bicarbonate solution per manufacturer. Onset: The test solution will be made by a mixing pen called "Onset"- This mixing pen Onset will deliver 0.18 mL of sodium bicarbonate solution into the anesthetic cartridge.
