The renmova1 of all organic matter - namely necrotic tissue, vital tissue, microbes, and their byproducts, is fundamental to most accepted forms of endodontic therapy Mechanical manipulations of the root canal system ultimately strive to clean the system of this organic matter while imparting a form which can be easily obturated. It is this organic substrate which produces the bacterial toxins and proteolytic enzymes which propagate and sustain lesions of endodontic origin. Sucessful resolution of the endodontic lesion requires that the organic substrate be totally eliminated from the root canal system, or that all portals of exit from the root canal system be permanently sealed to prevent egress of the toxins and enzy~es into the attachment apparatus. Accomplishing the total removal of the organic substrate is not an easy task. Many methods have been proposed, many instruments developed, and many chemicals employed to acriomplish the cleansing of the root canal system. The dental literature reports varied results for these proposals. Cleaning and shaping is one method proposed by Schilder to accomplish the removal of all organic matter and the development of a shape conducive to three dimensional hermetic sealing. Cleaning and shaping utilizes hand ... [TRUNCATED]
