The Efficacy of Buccal Infiltration of 4 Articaine and PSA Injection of 2 Lidocaine on Anesthesia of Maxillary Second Molars

摘要

Introduction:During the early mixed dentition period, the location of the deciduous maxillary second molar results in ineffectiveness of the infiltration technique in this area. In such cases, administration of posterior superior alveolar (PSA) nerve block is recommended; however, such a technique has some complications. The present study was undertaken to compare the effects of buccal infiltration of 4% Articaine and PSA technique with 2% Lidocaine on the success of anesthesia of maxillary deciduous second molars in 6 to 9-year old children.
