Obturation is a critical component of root canal therapy, and must both provide a complete seal for the root canal system and eliminate all avenues of leakage from the oral cavity. Historically, gutta-percha cones have been the standard material of choice for root canal obturation, used together with a sealer/cement. The first gutta-percha carrier-based obturating techniques were developed more than two decades ago. More recently, obturating techniques have been introduced that include resin-based sealers and obturators, syringe-applied heated gutta-percha, and the use of gutta-percha as an outer coating on obturator carriers composed of plastic or metal. It is important to select an obturation technique that offers consistency and is easy to use.
