Incidence of postoperative pain after single-visit and multiple-visit root canal therapy: A randomized controlled trial.

Background: Short-term complications after root canal therapy (RCT) include mild pain or flare-up. Patients regard these complications as a benchmark for the assessment of clinician's abilities. In this context, the evidence for recommending either one- or two-visit RCT is not consistent.

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.
