Disinfection of Root Canal Systems

Description

Root canal shaping serves two main purposes in canal disinfection: direct mechanistic elimination of intracanal tissue and pathogens and providing optimal space for irrigant and medicament delivery. The process of root canal preparation should be considered a main driver of clinical success in endodontics. Mechanical canal preparation does not create contact with the full radicular surface and therefore all mechanical preparation is incomplete. Mechanical instrumentation, alone or in combination with an inert flushing solution such as saline, is effective in significantly reducing bacterial load. Two basic concepts govern a numerical approach to root canal shaping procedures: working length (WL) and apical size, recently also described as working width (WW). This chapter discusses the potential negative effects of shaping on disinfection and clinical data to support specific shaping paradigms.
