Abstract

The present case series highlights the endodontic management of immature permanent teeth with blunderbuss canals using three different calcium silicate–based materials—Mineral Trioxide Aggregate (MTA), Biodentine, and Bio-C Repair. All three teeth exhibited open apices with periapical pathology and were treated using minimal instrumentation, calcium hydroxide intracanal medicament, and subsequent placement of 4–5 mm apical plugs. Clinical and radiographic evaluation at a six-month follow-up revealed complete periapical healing and evidence of apical barrier formation in all cases. The findings emphasize that calcium silicate–based materials are effective alternatives for one-step apexification, offering predictable sealing ability and favorable biological outcomes. Awareness of their properties and proper case selection are crucial to optimize clinical success in managing teeth with open apices.
