Details and patient eligibility

About

The goal of this clinical trial is to systematically compare the pain scores and anesthesia efficacy of IANB and MNB in the treatment of symptomatic mandibular first and second premolars. This study aims to address gaps in current evidence and clarify whether these anesthesia techniques differ in effectiveness and patient experience during endodontic procedures. The hypotheses include: (i) no difference in pain perception between IANB and MNB, (ii) no difference between first and second premolars with IANB, and (iii) no difference between first and second premolars with MNB.
