A comparison of two anesthesia methods for the surgical removal of maxillary third molars: PSA nerve block technique vs. local infiltration technique
نویسنده
چکیده
OBJECTIVES The purpose of this study was to compare the effect of PSA block injection with infiltration technique regarding local anesthesia for surgical extraction of upper third molar. MATERIAL AND METHODS A prospective, intra individual, single-blind randomized controlled trial was designed to study the severity of pain during injection and after surgical extraction of the bilaterally and symmetrically similar upper third molar in a total of 53 patients, in addition to evaluating the need to repeat the injection and requirement of post operative anti-inflammatory tablets. RESULT Although the average pain score for all studied times in PSA side was lower than the average pain score in infiltration technique, repeated statistical measures demonstrated that no significant pain reduction occurred in the two techniques. CONCLUSION The both tested methods have the same statistic equivalence for the surgical extraction of maxillary third molars. Key words:Surgical extraction, maxillary third molars, PSA block, infiltration.

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 infiltra...

BACKGROUND AND AIM: The effectiveness of buccal or lingual (B/L) infiltration of 4% articaine as supplemental injection for pulp anesthesia of mandibular teeth was confirmed in previous studies. However, this study was aimed to compare the effectiveness of 2% lidocaine as inferior alveolar nerve block (IANB) versus B/L infiltration of 4% articaine for pulp anesthesia, as primary injection in ma...
متن کاملComparison of the efficacy of two anesthetic techniques of mandibular primary first molar: A randomized clinical trial
BACKGROUND The most common technique to anesthetize mandibular primary teeth is inferior alveolar (I.A) nerve block injection which induces a relatively sustained anesthesia and in turn may potentially traumatize soft-tissues. Therefore, the need of having an alternative technique of anesthesia with a shorter term but the same efficacy is reasonable. The aim of this study was a comparison of th...
