Randomized Controlled Trial Comparative Study
Comparison of ropivacaine and articaine with epinephrine for infiltration anaesthesia in dentistry - a randomized study.
To compare the efficacy, onset time and duration of maxillary infiltration anaesthesia with 0.5% plain ropivacaine or 4% articaine with epinephrine 1 : 100 000 and to determine their possible influence on cardiovascular parameters. ⋯ Ropivacaine (0.5%) achieved effective and long duration of uninflamed pulp and soft tissue anaesthesia. Ropivacaine could be useful for long-lasting operative procedures without the need for a vasoconstrictor.
