Buffered Anesthetic Solution in the Treatment of Mandibular Primary Molars

In a prospective, randomized clinical trial, triple-blind, split-mouth study, 40 children aged between 7 to 10 with bilateral mandibular primary molars were diagnosed with pulpitis. The test agent was 2% lidocaine with 1:80.000 epinephrine buffered with sodium bicarbonate 8.4% at a ratio of 1/10, as opposed to the control agent, which was non- buffered 2% lidocaine with 1:80,000 epinephrine. The pain will be assessed during inferior alveolar nerve block injection (IANB) and the effectiveness of anesthesia using the subjective Wong-Baker visual analog scale, the objective sound, eye, and motor (SEM) scale, and the physiological pain scale (pulse rate) using a pulse oximeter. The investigator has confirmed the onset of anesthesia after lip tongue-numbing by probing the gingiva until there is no pain. Endo-ice has been used to assess the onset of pulp anesthesia.
