Long-acting local anaesthetics in oral surgery. Clinical evaluation of bupivacaine and etidocaine for mandibular nerve block.

2 long-acting local anaesthetics, bupivacaine and etidocaine, have been compared to lidocaine with regard to effect during surgical removal of impacted mandibular third molars and effect upon the immediate postoperative pain. It can be concluded from this study that both bupivacaine and etidocaine as well as lidocaine were highly effective and without significant difference with regard to pain blocking during surgery. Both long-acting solutions were significantly superior to lidocaine in providing an extended duration of postoperative pain control. Comparing the 2 long-acting solutions, patients in the bupivacaine group had a significantly longer pain-free period than patients in the etidocaine group.
