Oral surgical procedures are usually accompanied by severe and long lasting pain that intensify after the intervention and lasting several hours. Surgical practice had need for long-acting local anesthetics first applied since 1957. to provide indolence during and after the intervention that have proved to be effective for the suppresion for both intraoperative and postoperative pain. This paper is an overview of characteristics of long acting local anesthetics used in oral surgery, as well as our experience in their implementation.
Ropivacaine and bupivacaine has equal onset of effects and length of action, quality of anesthesia is higher than the bupivacaine, causes less motor block and has a less CVS and CNS toxicity then bupivacaine. We conclude that in case of need for the long acting local anesthetic, priority should be given to ropivacaine over etidocaine and bupivacaine.

Key words: local anestetic, ropivacaine, bupivacaine
