Obturation in Endodontics: The Final Stage of Root Canal Treatment #dentist

Obturation in endodontics 🦷 is the final and crucial phase of root canal treatment. It consists of filling and sealing the root canal system in a three-dimensional, airtight manner to prevent bacteria from entering, avoid reinfection, and promote tissue healing. 1. Main Objectives -Hermetic Seal: Seals the canal hermetically from the apical margin to the coronal entrance. -Isolation: Separates the root canal system from the periradicular tissues (the periodontium) and the oral cavity. 2. Materials Used -Gutta-percha: This is the primary material. It comes in the form of calibrated cones that are biocompatible, thermoplastic (moldable with heat), and viscoelastic. -Sealer Cement: Used in conjunction with gutta-percha to fill irregularities in the canal and ensure adhesion. Options include resins, zinc oxide-eugenol, and modern bioceramic cements.
