Articaine Infiltration Versus Lidocaine Inferior Alveolar Nerve Block for Primary Mandibular Molars: A Double-blind Randomized Controlled Clinical Trial.

To compare the effectiveness of articaine local infiltration with lidocaine inferior alveolar nerve block (IANB) for restorative treat- ment of primary mandibular molars (PMMs). In this double-blind, parallel-design, randomized, controlled, clinical trial, participants were enrolled according to specified inclusion criteria (four to 10 years of age, need of PMM restorations, Frankel four behavior) and randomly assigned into either an articaine or lidocaine group.
