Introduction: Mandibular third molar is the tooth that suffers from uneruption most frequently. A third molar that is impacted can eventually result in acute pain, an infection, tumours, cysts, caries, periodontal disease, and the loss of nearby teeth. For the third molar extraction, local anaesthesia is used. In this study, surgical extraction of bilaterally impacted mandibular third molars was tested using 2% lidocaine with 1:80,000 or 1:200,000 adrenaline
