Alzahrani F, et al. - Researchers compared the anesthetic effectiveness for pain and behavior during treatment with mandibular infiltration using 4% articaine (BI) vs inferior dental nerve clock (IDNB) using 2% lidocaine for extraction or pulp therapy in mandibular primary molars. This study included children aged 5–9 years old randomly assigned into two groups viz, BI supplemented by buccal intrapapillary infiltration with 4% articaine and IDNB with 2% lidocaine supplemented with long buccal infiltration. Equivalent success rates were noted for both the anesthetic techniques during treatment.
