Comparison of anesthetic efficacy of bupivacaine, lignocaine, articaine, and sterile saline for intrapulpal injections

Abstract

Background: Effective anesthesia in endodontic treatment in cases of pediatric patients is very important to achieve patients' co-operation. Profound anesthesia is required to access the chamber and extirpate the pulp. If patient discomfort is encountered, intrapulpal injection may be used as a supplement for pulpal anesthesia. Aims and Objectives: This study aims to analyze the efficacy of different anesthetic solutions and sterile saline for intrapulpal injections in primary vital teeth with irreversible pulpitits. Materials and Methods: Forty volunteers, patients with irreversible pulpitis whose pain persists after conventional anesthesia during treatment, were selected from Haldia. Patients were divided into four groups to administer intrapulpal solutions (bupivacaine, articaine, and lidocaine) and sterile saline to the respective groups to analyze the efficacy of the solutions in pain relief during pulp extirpation. Results: Positive back pressure was present in case of all anesthetic solution which was administered on the selected patients. Conclusion: On the basis of the results, we can conclude that effectiveness of intrapulpal injection is dependent on back pressure.
