Anesthetic efficacy of Articaine 4% during extraction of the first and second lower molar by using inferior alveolar nerve block and buccal infiltration techniques

Abstract

Purpose: The study was designed to evaluate the anesthetic efficacy of 4% articaine with 1:100000 adrenaline in infiltration and inferior alveolar nerve block (IANB) anesthetic techniques for the pain control during extraction of the mandibular posterior teeth. Materials and Methods: This crossovee clinical trial included 40 patients needing extraction of mandibular molar in both side. Patients received infiltration in the buccal vestibule opposite to the first molar supplemented with lingual infiltration in one side and standard IANB in other side with 4% articaine with 1:100000 adrenaline. For assessment of depth of anesthesia obtained by the two anaesthetic techniques, presence or absence of pain during the extraction were rated using the visual analog scale. Results: forty patients received infiltration anesthesia in one side and IANB in the other side. The success rate of pain-free extraction after buccal infiltration was 72.5%, whereas by using IANB with the same anesthetic it was 82.5%. No statistical differences were detected in the success rates between the two anesthetic techniques (P = 0.65). Conclusions: Buccal Infiltration can be considered a good option during extraction of the mandibular molar and premolar teeth of course, with supplemental lingual anesthesia.
