Intraligamentary vs Inferior Alveolar Nerve Block for Pulpitis: A Randomized Clinical Trial

This multicenter randomized trial compares the clinical effectiveness of intraligamentary injection versus inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis in mandibular molars. The goal is to determine which technique provides better pain control during endodontic treatment.

Symptomatic irreversible pulpitis in mandibular molars presents a clinical challenge due to the difficulty in achieving profound anesthesia. This prospective, randomized, controlled clinical trial evaluates two anesthetic techniques-intraligamentary injection (ILA) versus inferior alveolar nerve block (IANB)-to compare their efficacy in eliminating pain during endodontic access. Patients will be enrolled from multiple dental centers following standardized inclusion and exclusion criteria. Pain will be assessed using validated scales. Statistical analysis will be conducted to determine significant differences in anesthetic success between groups.
