Evaluate Buffering Local Anesthetic in Inflamed Teeth

Overview

This randomized, double-blinded, split-mouth clinical trial evaluates the effect of buffering local anesthetic with sodium bicarbonate in pediatric dental extractions. Twenty children aged 6 to 10 years with two infected primary molars on opposite sides of the maxilla participated. Each child received standard anesthetic on one side and buffered anesthetic on the other. Pain levels and onset time were measured to assess anesthetic efficacy.

This randomized, controlled, double-blinded, split-mouth clinical trial aims to evaluate the efficacy of buffering local anesthetic solution with sodium bicarbonate in the extraction of infected and inflamed primary molars in children. Infected tissues tend to have a lower PH , which can limit the effectiveness of local anesthetics by reducing the proportion of the active, non-ionized drug form. buffering with sodium bicarbonate improve anesthetic performance by raising the pH of the solution, enhancing its diffusion and clinical effectiveness. The study included 20 healthy children aged 6 to 10 years, each with two infected or inflamed primary molars located on opposite sides of the maxilla. A split-mouth design was employed, where each child received a standard local anesthetic solution - lidocaine 2% with epinephrine 1:80,000 - on one side, and a buffered solution (alkalinized with sodium bicarbonate) on the contralateral side. To assess anesthetic efficacy, three parameters were measured: pulse rate (as a physiologic indicator of pain), the Sound-Eye-Motor (SEM) scale (for behavioral response), and the Wong-Baker Faces Pain Rating Scale (for subjective pain reporting). Onset time of anesthesia was also recorded. The study aims to determine whether buffering lidocaine with sodium bicarbonate improves pain control and onset time during pediatric dental extractions in inflamed and infected tissues.
