Abstract


Objective: To evaluate the anesthetic efficacy and the need for additional intraligamentary anesthesia in patients with advanced chronic periodontitis after anesthesic block for inferior alveolar nerve, lingual and buccal using two different anesthesics.
Method: We selected 30 patients with advanced chronic periodontitis and with indication for extraction of at least two lower teeth, one on each side of the mandible. 60 anesthesic blocks performed in two sessions with one week between sessions: 30 blocks of articaine 4% with epinephrine 1:100,000 and 30 blocks of lidocaine 2% with epinephrine 1:100,000. The pain was measured using a faces analogue scale in which patients rated the pain felt in scores ranging from 0 (no pain) to 5 (hard pain) and, scores higher than 2 in moment post anesthesia, indicated the need for intraligamentary supplementary anesthesia. The statistical test of Mann-Whitney was used to compare the anesthetic efficacy and the need for additional anesthesia and the results were considered statistically significant when p < 0.05.
Results: When comparing the success of the two anesthetic solutions, there was a significant statistically difference (p = 0.0337), as well as the need additional anesthesic technique (intraligamentary anesthesia), where only 16.7% of patients anesthetized with articaine needed to supplement anesthesia. With lidocaine that percentage increased to 46.7%, showing the superiority of articaine 4% with epinephrine 1:100,000.
Conclusion: The articaine 4% with epinephrine 1:100,000 was better than the lidocaine 2% with epinephrine 1:100,000 in both item anesthetic success as in need of additional intraligamentary anesthesia.
