Abstract

Background: Local anesthesia plays a crucial role in minimizing patient discomfort during dental extractions. Lignocaine, a commonly used local anesthetic, is typically buffered with sodium bicarbonate to reduce injection pain. The purpose of this study was to compare the effectiveness of lignocaine buffered with 8.4% sodium bicarbonate in the ratio of 4:1 versus 9:1 versus unbuffered lignocaine during surgical extraction of impacted mandibular molars with a history of Pericoronitis.


Aim and Objectives: This study aims to study the effects of using buffered local anesthesia as opposed to conventional local anesthesia for surgical extraction of impacted mandibular molars. The objectives include measurement of pain experienced by the patient during administration of local anesthesia and during the procedure, and the measurement of onset and duration of action of anesthesia.


Materials and Methods: This is a prospective, split-mouth study. 56 patients requiring bilateral surgical extraction of mandibular third molars were given conventional local anesthesia on one side and the procedure was done, and local anestheisa buffered with 8.4% Sodium Bicarbonate in the ratio 5:1 on the opposite side, after a period of 7 days. The VAS score was recorded after administration of LA and after completion of the procedure, the onset and duration of action of local anesthesia was recorded and compared on both sides.


Results: Results showed that local anethesia buffered with sodium bicarbonate showed was significantly reduced pain at the time of administration and during the procedure. (P< 0.05). the onset and duration of action was also lower for buffered local anesthesia.


Conclusion: Local anesthesia buffered with sodium bicarbonate significantly reduces the pain experienced, and the onset of action of the anesthetic agent. The duration of action is also increased. This data can be safely used to advocate for the use of buffered LA over conventional LA for the extraction of mandibular third molars.
