ABSTRACT
Objective To compare the the infiltration anesthesia effect of compound articaine and lidocaine in anterior teeth anesthesia.Methods 100 patients with irreversible pulpitis of anterior teeth(137 teeth)were selected.According to the different anesthesia drugs,the patients were divided into two groups.The observation group was given compound articaine anesthesia,and the control group was given lidocaine infiltration anesthesia.The clinical anesthetic effect of the two groups was evaluated.Results The total effective rate of infiltration anesthesia in the observation group was 100.00%,which was significantly higher than 95.38% in the control group(x2=3.654,P0.05).Conclusion The effect of ropivacaine for a compound infiltration effect than lidocaine on anterior teeth infiltration,pain reaction is small,and has higher security.
