Comparative evaluation of anesthetic efficacy of 1.8 mL and 3.6 mL of articaine in irreversible pulpitis of the mandibular molar: A randomized clinical trial.

ABSTRACT:

Objective

The aim of this study was to compare the anesthetic efficacy of two volumes of articaine in conventional inferior alveolar nerve block (IANB) of mandibular molars with irreversible pulpitis, and in cases of anesthetic failure, its complementation with periodontal ligament injection (PDL).

Methods

Ninety patients with irreversible pulpitis in mandibular molars received conventional IANB with 1.8 mL or 3.6 mL of 4% articaine with 1:100,000 epinephrine. In cases of IANB failure, the same volumes were administered in the PDL. Presence of pulpal anesthesia and absence/presence of pain during pulpectomy were evaluated by electric pulp stimulation and verbal analogue scale, respectively. Relative risks (RR) with corresponding 95% confidence intervals (95% CI) were calcula
