NCT04055116

Brief Summary

Local anesthetic buffered with sodium bicarbonate has been suggested to reduce pain, discomfort and onset time of local anesthesia on injection into tissue, compared to non-buffered solutions. Buffered local anesthesia has been used in medicine, however intraoral injections with buffered solutions are less common in dentistry. Most research has focused on adult perception of pain on administration of buffered local anesthetic. There have been few studies and inconclusive evidence to show that buffered lidocaine reduces the perception of pain on administration in children. The purpose of this interventional study is to assess pain reduction and onset time on injection of buffered 2% lidocaine with 1:100,000 epinephrine in children.

Outcome Measures

Primary Outcomes (1)

  • Patient Reported Pain Perception

    Wong-Baker FACES Pain Rating Scale responses after buffered and non-buffered lidocaine. Range: 0 - No Hurt to 10 - Hurts Worst (higher numbers indicate higher levels of pain). There are no sub-scores.

    Within 1 minute of anesthetic administration

Secondary Outcomes (1)

  • Onset of Soft Tissue Anesthesia

    Time of injection to 4 minutes post-injection (tested in 15 second intervals).

Other Outcomes (1)

  • Provider Reported Pain Perception

    During local anesthesia administration

Study Arms (2)

Unbuffered Lidocaine, then Buffered Lidocaine

EXPERIMENTAL

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.

Drug: Buffered Lidocaine

Buffered Lidocaine, then Unbuffered Lidocaine

EXPERIMENTAL

Investigator will prepare 1:10 dilution of sodium bicarbonate to 2% lidocaine with 1:100,000 epinephrine on one occasion.Subjects will receive an injection of this 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. We will use 8.4% Sodium Bicarbonate manufactured by Hospira, Inc. Lake Forest, IL

Drug: Buffered Lidocaine

Interventions

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.
