Comparison of Efficacy of 0.5% Levobupivacaine and 2% Lignocaine as Local anesthetic in Extraction of Mandibular Molars.

Abstract

Introduction: Managing pain efficaciously is of utmost importance during and after dental extractions. Achieving good anesthesia ensures not only patient’s comfort but also facilitate smoother surgical procedure and instils positive attitude in patients. 2% Lignocaine with adrenaline (1:80000) is commonly and widely used as anesthetic agent in dental procedures. 0.5% Levobupivacaine has nowadays emerged as good alternative to lignocaine for its prolonged anesthetic effect.

Objectives: To compare efficacy of 0.5% levobupivacaine and 2% lignocaine with adrenaline (1:80000) used for extraction of mandibular molars in terms of Onset of action, Duration of anesthesia and Intraoperative pain control.

Methods: 30 patients requiring extraction of mandibular molars were chosen for study. Participants were randomly allocated into two groups. Group A received 2% Lignocaine with adrenaline (1:80000) as anesthetic agent while Group B received 0.5% Levobupivacaine as anesthetic agent. Parameters assessed were onset and duration of Local anesthetic, intraoperative pain.

Results: Onset of action was significantly faster with lidocaine with adrenaline while levobupivacaine showed longer duration of action and lesser intraoperative pain.

Conclusions: Levobupivacaine 0.5% is effective alternative to lidocaine with adrenaline offering prolonged anesthesia and good intraoperative pain control.
