Comparison of ropivacaine and articaine with epinephrine for infiltration anaesthesia in dentistry – a randomized study
International Endodontic Journal, 04/15/2011
Krzeminski TF et al. – Ropivacaine (0.5%) achieved effective and long duration of uninflamed pulp and soft tissue anaesthesia. The mean onset time was significantly shorter for ropivacaine (2.22 min) when compared with articaine (4.08 min). The duration of action and soft tissue anaesthesia were also significantly longer for ropivacaine (79.2 and 264 min) when compared with articaine (63.7 and 195.2 min, respectively). Ropivacaine caused significant increases in blood pressure and heart rate.
