Recent Advances in Obturation System

The success of root canal treatment depends upon proper diagnosis, treatment planning, Knowledge of canal anatomy ,morphology, canal debridement, sterilization of canal and Obturation.Obturation of root canal and to eradicate all portals of entry between the periodontium and root canal are the objectives of root canal filling. The better the seal, the better the prognosis of the tooth.Techniques for obturating root canals include the use of heat or chemically-softened gutta percha, injection techniques, ultrasonics, vibration and carriers. Carrier based materials are available that utilize a core carrier around which obturating material is coated. The introduction of bonded obturating materials (methacrylate resins) has endorsed the clinician to obtain a bonded seal to the root canal dentin in areas reached by the etch/adhesive materials. Besides, a carrier-based system is now available that combines a carrier technique and adhesive technology for bonded obturation.For successful outcomnes, the apppropiate use of the selected materials and techniques, radiographic control using different phases of endodontic therapy and a high degree of clinical expertise are required.
