Abstract
Aim: Articaine, bupivacaine, lignocaine are amide type of local anesthetic agents, which are of almost equal potency. However, lidocaine is considered the gold standard and is the most widely used anesthetic agent because of its potency, safety, and efficiency. Articaine is fast acting and bupivacaine is long lasting local anaesthesia. The aim of this clinical study was to evaluate and compare the clinical anesthetic efficacy of 4% articaine and 0.5% bupivacaine and 2% lignocaine in therapeutic orthodontic extractions.
Materials and Methods: A 150 healthy patients, requiring Maxillary premolars extraction for orthodontic reasons were included. Patients were categorized into three groups (4% articaine and 0.5% bupivacaine, 2% lignocaine) in a crossover manner. Subjective and objective observations recorded that include age, gender, and pain score using visual analog scale. At the first appointment, both upper premolars were extracted on one or two sides of the jaws. Each patient was evaluated using a visual analogue scale.
Results: The results showed that 0.5% Bupivacaine had significantly faster onset of action and lower visual analogue scores when compared with articaine and lignocaine. However, the duration of analgesia and need of first rescue analgesic medication was longer in the bupivacaine group.
Conclusion: Within the limitations of study we found that Bupivacaine has the best anaesthetic effect with low pain scores followed by Articaine and followed by Lignocaine. Bupivacaine is an alternative local anaesthetic drug for performing therapeutic orthodontic extractions.
