Objective: The goal of this study was to evaluate the efficacy and pain perception status of patients receiving Inferior Alveolar Nerve Block (IANB) for third molar extraction using both closed mouth and open mouth techniques. Place of study: This research was conducted from February 2018 to November 2018 in Nishtar Institute Of Dentistry Multan for ten months. Patients and Methods: in this study, 90 patients were enrolled. For the extraction of the mandibular third molar, three different techniques are used, and for this purpose, patients were given inferior alveolar nerve block. In this study, 30 patients were divided into three groups in which conventional open mouth, Fischer 1,2,3 technique, closed mouth Vazirani Akinosi technique were assigned with group 1, 2, 3, respectively. Patient anxiety, speed of anaesthesia, clinician expertise, and pain perception were measured. Results: The results show that compared to Vazirani-Akinosi and Fischer's 123 techniques, the intra-oral traditional technique is less technique sensitive. In terms of less skill needed as well as pain tolerance by the patient, Former still is the strongest. Conclusion: The traditional open mouth technique is still the most common option among clinicians, and among patients with this classic intra-oral technique, pain sensitivity is also negligible. The technique of indirect and closed mouth needs more qualified experience, but can be used in cases with the minimum opening of the mouth.
