Abstract
Question: In patients requiring maxillary lateral incisor infiltration is ropivacaine as effective as bupivacaine?
Objective To compare the anaesthetic efficacy of 0.5% ropivacaine with and without 1:200,000 epinephrine and 0.5% bupivacaine with 1:200,000 epinephrine in maxillary lateral incisor infiltrations.
Design Randomised controlled trial in hospital setting.
Intervention Forty subjects received three sets of injections randomly assigned at three separate appointments at least 1 week apart. Topical anaesthesia was used at the injection site.
Outcome measures Subject rated pain of insertion, placement and deposition. Depth and duration of anaesthesia, onset and duration of lip numbness and post injection discomfort.
Results See Table 1
Conclusion The pharmacological action of 0.5% ropivacaine with 1:200,000 epinephrine is equivalent to 0.5% bupivacaine with 1:200,000 epinephrine for maxillary lateral incisor infiltrations.
