ABSTRACT
Context: Control of pain during dental treatment is an essential aspect of pediatric dentistry. Aims: This study was conducted to evaluate and compare the anesthetic efficacy of 4% articaine buccal infiltration with 2% lignocaine inferior alveolar nerve block (IANB) for primary mandibular molar extractions. Settings and Design: The study was a prospective, split-mouth, randomized controlled trial. Methods: Bilateral symmetrical carious primary mandibular molar (n = 92) extractions in 46 healthy children aged 5–10 years were included in this randomized controlled trial. Extraction was performed on one side using 4% of articaine buccal infiltration and on the contralateral side using 2% lignocaine IANB in two subsequent appointments. Pain and behavior were assessed at baseline, during injection and extraction using Wong–Baker Faces Pain Rating Scale, Modified Behavior Pain Scale (MBPS), and Frankl Behavior Rating Scale. Statistical Analysis Used: Values thus obtained were statistically analyzed by one-way analysis of variance test and compared using independent samples test. Results: According to MBPS, the mean value of pain experienced in the form of cry during injection was reported to be more for 2% lignocaine IANB (1.76) as compared to 4% articaine buccal infiltration (1.30), which was statistically significant (P = 0.024). Comparison of behavior depicted showed no statistically significant difference between the groups. Conclusion: Buccal infiltration with 4% articaine can be utilized as an effective alternative to 2% lignocaine IANB for primary mandibular molar extractions.
