Background: The extraction of teeth is based on the choice of local anaesthesia which has three main clinical considerations i.e. anesthetic potency, latency and duration of the anesthetic affect. The present study was conducted to compare the two anaesthesia methods for the surgical removal of maxillary third molars. Material and methods: The present study was conducted to evaluate the efficacy of PSA nerve block technique and infiltration technique for extraction of maxillary 3rd molar. In our study total sample size was 40 who underwent a surgical removal of symmetrically bilaterally impacted upper third molars age ranged between 18 and 30 years. Each of the 40 patients was scheduled to undergo bilaterally and symmetrically identical upper third molar surgical extraction. In each patient, the choice of which anesthetic techniques were going to be administered, the PSA block technique and on the contra lateral side the infiltration technique was done. The palatal injection was combined to both techniques. Preoperative pain assessed by a professional operator who was different from the surgeon who performed the surgery. Each record was repeated three times on every case: during the injection, at the end of operation and after 15 minutes from the end of operation by using visual analogue scale. The data was analysed using SPSS version 22 (SPSS Inc. Chicago, Illinois, USA). The pain VAS scores were analyzed by analysis of variance (ANOVA) for repeated measures. Results: Patients with weak pain intensity during injection was more with PSA(60%). Patients with no pain at the end of operation was more with PSA(80%). Patients with no pain after 15 minutes of the procedure was more with PSA(90%). Conclusion: Our study concluded that PSA was better than infiltration.
Key words: PSA, infiltration, palatal.
