Abstract
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.
Highlights
Surgical extraction of impacted teeth can be either uneventful and uncomplicated, or difficult, with considerable postoperative pain. [1] Maxillary third molars are frequently amenable to removal surgically under local anesthesia [2] .Fear of a dental injection and postoperative pain can prevent patients from seeking dental care and often this fear is related to the feeling of needle penetration and pain during the injection [3]
The average pain score for all studied times in posterior superior alveolar (PSA) side, was lower than the average pain score in infiltration technique, repeated-measures analysis of variance (ANOVA) demonstrated no significant difference in pain reduction between the two techniques (P > 0.05, Table 1, Fig. 2)
The pain control is an important factor for reducing the fear and anxiety associated with dental procedures [12] for that the choice of local anesthetic techniques may influence the amount of discomfort produced during intraoral injection in order to propose an easy and safe method to anesthetize the dentition and surrounding hard and soft tissues during management of surgical extraction [13]

[1] Maxillary third molars are frequently amenable to removal surgically under local anesthesia [2] .Fear of a dental injection and postoperative pain can prevent patients from seeking dental care and often this fear is related to the feeling of needle penetration and pain during the injection [3]. The majority of the recently published articles evaluate the anesthetic efficacy of the PSA nerve block and maxillary infiltrations either in inflamed pulps or in the normal tooth extraction [6,7,8]. To the knowledge of the author, there is no published data evaluated and compared in terms of the severity of pain during injection and after the surgical extraction of upper third molar, and the need to repeat the injection and requirement of antiinflammatory tablets
