Abstract
An endodontic post comprises a combined endodontic post and tip of filling material such as thermoplastic material in a single unit. Obuturating systems are provided by an endodontic carrier and attached filling material. The post and obturator include a protrusion or depression on the tip section of the device for better attachment of the filling material to the device. Alternatively the post and obuturator are fabricated of a tube having a tunnel extending therethrough into which filling material is injected. The filling material extends out of the apical section of the post and obturator to form a filler cone.
