Comparative evaluation of anesthetic efficacy of inferior alveolar nerve block and inferior alveolar nerve block plus buccal or lingual infiltration using articaine in mandibular molars with irreversible pulpitis: a preliminary prospective randomized single-blind clinical trial.

Objectives: This study was designed as a prospective randomized single-blind clinical trial to compare the anesthetic efficacy of inferior alveolar nerve block (IANB), IANB plus buccal infiltration, and IANB plus lingual infiltration of 4% articaine with 1:100,000 epinephrine in mandibular molars with irreversible pulpitis.

Method And Materials: Sixty healthy volunteers who had a first or second mandibular molar diagnosed with irreversible pulpitis participated in the present study. This study was composed of three arms for the first molar and three arms for the second molar.
