Modified Obturation Strategy Using the Piston Technique With a Calcium Silicate-Based Sealer

A new obturation protocol for immature necrotic mandibular second molars that employs a piston-driven delivery system to place a calcium silicate-based sealer, aiming to improve the seal, reduce procedural errors, and enhance long-term root‑canal success. This technique is relevant for endodontic specialists treating immature teeth.
