Single-Visit Endodontic Management of a Mandibular Molar with Symptomatic Irreversible Pulpitis

This case demonstrates the successful management of symptomatic irreversible pulpitis in a mandibular first molar through single-visit endodontic therapy. Patient Presentation & Diagnosis: The patient presented with symptoms consistent with symptomatic irreversible pulpitis. The preoperative radiograph revealed a deep distal carious lesion approaching the pulp chamber, with no evidence of periapical pathology. A diagnosis of symptomatic irreversible pulpitis was confirmed, and a single-visit, non-surgical root canal treatment was planned. Treatment Protocol: Following the administration of local anesthesia, the tooth was isolated using a rubber dam to ensure an aseptic operating field. A conservative access cavity was prepared, revealing three canal orifices (mesiobuccal, mesiolingual, distal). Working lengths were determined using an electronic apex locator and confirmed with a radiograph. The canals…
