Pulpal-anesthesia of a mandibular first molar with irreversible pulpitis by inferior alveolar nerve block plus buccal infiltration using articaine or lignocaine.

Introduction: This study aims to compare the efficacy of a combination of an inferior alveolar nerve block (IANB) plus buccal infiltration using 4% articaine versus 2% lignocaine in achieving anesthesia of lower first molar teeth with irreversible pulpitis.

Materials And Methods: Seventy adult patients were selected. A random sequence list was employed to administer IANB plus buccal infiltration.
