Comparative Evaluation of Pulpal Anaesthetic Efficacy of Different Anaesthetic Solutions for Inferior Alveolar Nerve Block in Patients With Symptomatic Irreversible Pulpitis

Pulpal and periapical inflammation and infection can cause tissue pH in the affected region to be lowered which results in less penetration of anesthetic solution in the nerve membrane and hence delays the onset of anesthesia. So, the purpose of this study was to compare the pulpal anesthetic efficacy of lidocaine, articaine, mepivacaine for inferior alveolar nerve block (IANB) in patients with irreversible pulpitis (IP). One hundred and twenty adult patients with IP concerning mandibular molars randomly received IANB with either of the three solutions: 2% lidocaine with epinephrine; 4% articaine with epinephrine; 3% plain mepivacaine. Pain during the endodontic treatment was assessed using a visual analog scale (Heft-Parker VAS). Endodontic treatment was initiated. Success was defined as no or mild pain (pain score≤54mm on Hp VAS) during access preparation and root canal instrumentation. The anesthetic success rates were analyzed with the chi-square test.

Primary outcomes

  1. Anesthetic Success

    Time frame: 15 minutes after the inferior alveolar nerve block

    Pain during the endodontic treatment was assessed using a visual analog scale (Heft-Parker VAS). Success was defined as no or mild pain (pain score≤54mm on Hp VAS) during access preparation and root canal instrumentation.
