Aim
The aim of this study was to compare anesthetic latency and efficacy of articaine and lignocaine in surgical extraction of impacted mandibular third molars.
Methods
A prospective randomized double-blind clinical trial was conducted on 20 subjects planned for elective surgical removal of bilateral impacted mandibular third molars with similar difficulty indices. A single operator performed surgery on an extemporaneous basis using 4% articaine or 2% lignocaine as the anesthetic agent and with the same concentration of vasoconstrictor (epinephrine 1:100,000). The parameters considered were latency, duration of anesthetic effect and the need for re-anesthesia for the surgical procedure. A visual analog scale was used to score pain during procedure.
Results
The differences in latency with 4% articaine (66.65 ± 12.3 s) and 2% lignocaine (72.95 ± 9.4 s) and mean duration of anesthetic effect (240.3 ± 29.6 min for 4% articaine and 173.4 ± 18.6 min for 2% lignocaine) were found to be statistically significant and the pain scores obtained were on the higher end for lignocaine but were not statistically significant (2.15 for 4% articaine and 3.75 for 2% lignocaine).
Conclusions
The results suggest that 4% articaine is superior to 2% lignocaine in terms of latency, duration of the anesthesia and pain control in surgical removal of impacted mandibular third molars, although a multicentric study with a larger sample size is essential to validate the findings with statistical correlation.
