SUCCESSFUL REMOVAL OF A CAST POST AND CORE USING LITTLE GIANT POST PULLER AND SURGICAL OPERATING MICROSCOPE

Abstract

The long, cast post and core in the root canal of a maxillary anterior tooth can be efficiently removed using the Little Giant Post Puller, and by accurately cutting both the post core and the mesio-distal tooth under a surgical operating microscope. If the thickness of the residual tooth, which is the fulcrum for the legs of the Little Giant Post Puller, is at least 1.5 mm, the cast post and core can be removed without breaking the tooth root. With this method, such cores can be removed in a safe and minimally invasive manner, without cutting the dentin around the post. This method is effective for the retreatment of all such root canals, particularly those with an X-ray transmission image at the apex.
