Anesthetic effect of articaine and lidocaine in tooth extraction

The safety and efficiency of 4% articaine compared to 2% lidocaine for tooth extraction is of interest to dentists. Hence, a total of 30 patients requiring premolar tooth extraction for orthodontics reason were randomly divided into 2 groups namely (1) articaine and (2) lidocaine. Parameters such as onset of action, duration of anaesthesia and need to re-anesthetize at the surgical zone are evaluated. Pain evaluation was done with visual analog scale (VAS). Data shows that 4% articaine had a shorter onset of action and longer duration of anaesthesia compared to lidocaine.
