Local anesthesia in endodontics - Click here

Effective local anesthesia is critical for pain control during endodontic procedures, particularly in teeth with irreversible pulpitis, where anesthesia is often difficult to achieve.

Commonly used techniques include inferior alveolar nerve block (IANB) for mandibular teeth, supraperiosteal infiltration for maxillary teeth, and supplemental techniques such as intraligamentary, intraosseous, and intrapulpal injections when conventional anesthesia is inadequate.

Anesthetic agents like 2% lidocaine with epinephrine, 4% articaine, and 3% mepivacaine are widely used. Articaine is especially effective for supplemental infiltrations. Factors affecting anesthetic success include inflammation, altered tissue pH, anatomical variations, and patient anxiety.

Proper technique, appropriate anesthetic selection, and use of supplemental anesthesia ensure predictable pain control and patient comfort during endodontic treatment.
