Objective:
To compare the efficacy of different local anesthetics in managing pain during the surgical removal of palatally placed impacted maxillary canines.
Materials And Methods:
A randomized controlled study was conducted on 90 patients requiring surgical removal of palatally impacted maxillary canines. Patients were divided into three groups, each receiving a different local anesthetic: 2% lidocaine with epinephrine (Group A), 4% articaine with epinephrine (Group B), and 0.5% bupivacaine with epinephrine (Group C). Pain levels were assessed intraoperatively and postoperatively using the Visual Analog Scale (VAS).
Results:
Articaine demonstrated superior intraoperative pain control compared to lidocaine and bupivacaine (VAS score: 1.5 ± 0.6 vs. 3.2 ± 0.8 and 2.8 ± 0.7, respectively, P < 0.05). Postoperative pain relief was significantly prolonged in the bupivacaine group (VAS score at 6 hours: 2.1 ± 0.9 vs. 4.5 ± 1.0 for lidocaine and 3.8 ± 0.9 for articaine, P < 0.05). No severe adverse effects were reported in any group.
Conclusion:
Articaine provides superior intraoperative pain control, while bupivacaine offers longer-lasting postoperative analgesia. The choice of anesthetic should depend on the clinical requirements of intraoperative versus postoperative pain management.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
