n=28 Participants
Subjects will receive an injection of non-buffered 2% lidocaine with 1:100,000 epinephrine on one occasion; they will be randomized to this group. After a minimum of one week, subjects will receive the alternate solution. Buffered Lidocaine: Investigator will prepare 1:10 dilution of sodium bicarbonate to 2% lidocaine with 1:100,000 epinephrine on one occasion. 8.4% Sodium Bicarbonate will be used.

OTHER_PRE_SPECIFIED outcome

Timeframe: During local anesthesia administration

Faces, Legs, Arms, Crying Consolability (FLACC) Behavioral Pain Scale. This scale helps clinicians assess patients' pain based on behavioral observations. Range: 0 - 2 per category (higher number indicates more observed agitation/potential pain). A score is given in each of the five categories (Faces, Legs, Arms, Crying, Consolability). The sum of these scores provides the Assessment of Behavioral Score (range: 0 - 10) with higher scores indicating higher levels of pain.
