Randomized Controlled Trial Comparative StudyA prospective randomized double-blind study to assess the latency and efficacy of twin-mix and 2% lignocaine with 1:200,000 epinephrine in surgical removal of impacted mandibular third molars: a pilot study.
A prospective randomized double-blind study was conducted to assess the latency and duration of pterygomandibular nerve block with a mixture of 1.8 ml 2% lignocaine with 1:200,000 epinephrine and 1 ml of 4 mg dexamethasone and its impact on postoperative sequelae of surgical extraction of impacted mandibular third molars. ⋯ The addition of dexamethasone to lignocaine and its administration as an intra-space injection significantly shortens the latency and prolongs the duration of the soft tissue anesthesia, with improved quality of life in the postoperative period after surgical extraction of mandibular third molars.
