ABSTRACT

Background and Aim: The inferior alveolar nerve block is the most frequently used injection technique for achieving local anesthesia for mandibular restorative and surgical procedures of the posterior region. Infiltration anesthesia for the posterior region of the mandible has been routinely avoided because of its questionable effectiveness related to the dense cortical bone of the mandible. This study compares the effectiveness of inferior alveolar nerve block and infiltration in the extraction of posterior mandibular teeth. Material and Methods: In this prospective study, 100 patients with age range between 18-75 years, who came to the Tertiary care Institute for extraction of mandibular molars and premolars were included. Total of 100 patients were divided into two groups. Group 1 included 50 patients and for each tooth, two injections were administered, whereas Group 2 included 50 patients and were given Inferior Alveolar Nerve Block and Long Buccal nerve Infiltration. Results: In our present study, we found 78% patients was pain free and 22% was feeling pain during tooth extraction in patients who were given infiltration, whereas patients in which Inferior alveolar nerve block was given, 88% patients was pain free and 12% were feeling pain during tooth extraction. Conclusion: Infiltration can be used as an alternative approach to inferior alveolar nerve block during the extraction of Mandibular posterior teeth.
