Modified Piston Technique with Calcium Silicate Sealer for Immature Necrotic Mandibular Molar

This obturation strategy employs a piston-driven delivery of a calcium silicate–based sealer into the root canal of an immature necrotic mandibular second molar, enhancing seal integrity and promoting periapical healing. The technique is indicated for immature teeth with necrotic pulps where conventional obturation is challenging. It offers improved apical sealing and biocompatibility, benefiting endodontic restorative practice.
