Anesthetic efficacy of 4% articaine buccal infiltration in the urgency treatment of mandibular molars with symptomatic irreversible pulpitis: a randomized clinical trial

The aim of this study was to evaluate the anesthetic efficacy 4% articaine by buccal infiltration technique (BI) after inferior alveolar nerve block (IANB) with 2% mepivacaine, both 1:100,000 epinephrine, in urgency treatment mandibular molars symptomatic irreversible pulpitis (SIP). This a prospective study, randomized, blinded, controlled parallel clinical trial experimental design. Thirty patients diagnosed SIP were randomly assigned, and control group (G1) received IANB 1.8 mL mepivacaine while (G2) also supplemental BI articaine. To efficacy, addition lip numbness test, electric pulp testing (EPT) used. Additionally, visual analogue scale verified presence pain. Two-way ANOVA Chi-square tests applied at significance level 5%. There reduction pain perception two techniques (p<0.001), no difference between groups (p=0.479). 26.6% for 40% plus (G2), without significant treatments (p=0.699). did not significantly increase success SIP.
