Clinical Trial Summary

The purpose of this study is to determine the effect of buffered lidocaine (a numbing solution) on the ability to numb patients with toothaches. Buffered anesthetic (numbing) solutions have shown promise in some medical and dental research. Patients presenting with toothaches will be given either a buffered numbing solution or a nonbuffered numbing solution. Neither the patient nor the operator will know which solution they will receive. Root canal treatment will be performed on the tooth and the ability of the buffered versus non-buffered numbing solutions will be compared.

Outcome

Type Measure Description Time frame Safety issue
Primary Percent of Patients With Successful Anesthesia (% of Patients Able to Have Treatment Without Additional Anesthesia) pain at time of treatment (after buffered versus nonbuffered numbing solution) average of 15 minutes after injection
Primary Effect of Buffered Lidocaine on the Success of the Inferior Alveolar Nerve Block in Patients With Symptomatic Irreversible Pulpitis. 100 patients diagnosed with symptomatic irreversible pulpitis of a mandibular posterior tooth randomly received a conventional inferior alveolar nerve block (IAN) block using either 2.8 ml of 4% lidocaine with 1:100,000 epinephrine or 2.8 ml of 4% lidocaine with 1:100,000 epinephrine buffered with sodium bicarbonate in a double-blind manner. For the buffered solution, each cartridge was buffered with 8.4% sodium bicarbonate to produce a final concentration of 0.18 mEq/mL of sodium bicarbonate. Fifteen minutes after administration of the IAN block, profound lip numbness was confirmed and endodontic access was initiated. Success was determined as no or mild pain on access or instrumentation of the root canal. Higher numbers on the VAS are indicative of more pain and less success and the VAS scale ranged from 0 to 170 mm. approximately 15 minutes after injection
