Abstract

Background: The purpose of this study was to compare the pain perception and anesthetic efficacy of 2% lignocaine with 1:200,000 epinephrine, buffered lignocaine, and 4% articaine with 1:200,000 epinephrine for the inferior alveolar nerve block.
Methods: This was a double-blind crossover study involving 48 children aged 5?10 years, who received three inferior alveolar nerve block injections in three appointments scheduled one week apart from the next. Pain on injection was assessed using the Wong-Baker Faces pain scale and the sound eye motor scale (SEM). Efficacy of anesthesia was assessed by subjective (tingling or numbness of the lip, tongue, and corner of mouth) and objective signs (pain on probing).
Results: Pain perception on injection assessed with Wong-Baker scale was significantly different between buffered lignocaine and lignocaine (P < 0.001) and between buffered lignocaine and articaine (P = 0.041). The onset of anesthesia was lowest for buffered lignocaine, with a statistically significant difference between buffered lignocaine and lignocaine (P < 0.001). Moreover, the efficacy of local analgesia assessed using objective signs was significantly different between buffered lignocaine and lignocaine (P < 0.001) and between lignocaine and articaine.
Conclusion: Buffered lignocaine was the least painful and the most efficacious anesthetic agent during the inferior alveolar nerve block injection in 5?10-year-old patients.
