    Abstract:
    PURPOSE: The aim of this study was to compare single buccal infiltration of 4% articaine versus routine buccal and palatal injections of 2% lidocaine during bilateral extraction of maxillary primary molars. METHODS: Thirty healthy children aged 6-9 years old requiring bilateral extraction of maxillary primary molars were enrolled into the trial. Randomization was performed in two steps. Routine buccal and palatal infiltrations were administered using 2% lidocaine in the control side. Four percent articaine was used for single buccal infiltration in the intervention side. WBFP scale (Wong-Baker FACES Pain scale) was employed for subjective assessment of pain. For objective evaluation of pain, FLACC scale (Face, Legs, Activity, Cry, Consolability) and physiological parameters of blood pressure and pulse rate were recorded. RESULTS: Analyses did not show any significant differences in blood pressure, pulse rate, and FLACC scale between groups (P value > 0.05). However, statistically lower WBFP scores were observed in articaine group as compared to lidocaine group (P value < 0.05); the difference was less than one unit which is not clinically considerable. CONCLUSION: Single buccal infiltration of 4% articaine can be administered as an alternative for conventional infiltration of 2% lidocaine to avoid fear or uncooperative behavior of the child patient. However, the assessment of palatal tissue anesthesia is quite necessary before the procedure is initiated. In case of failure in achieving palatal anesthesia, a palatal injection should be given.
