REcent root canal filling materials and techniques - A review

Obturation is the most important step in the triad of endodontics. Carefully and properly achieved obturation will lead to the formation of “fluid tight seal” which is essential for the success of the endodontic treatment. Over the past decade, the science & practice of root canal therapy has changed dramatically on evidence based protocols to develop highly advanced obturation materials and techniques. Gutta percha with sealer is the most versatile obturating material. But it has very big disadvantage that it does not bond to the root canal dentin. To overcome this drawback, bonded resin materials where developed. Many parelling techniques, materials where developed to improvise the obturation of the root canal. They include heat, injection, vibration, compaction & carrier based system. In this article all the root canal filling materials and techniques available at present are discussed.
