Newly revised and updated, Fundamentals of Periodontal Instrumentation and Advanced Root Instrumentation, Ninth Edition is an instructional guide to periodontal instrumentation that takes students from the basic skills -- patient positioning, intraoral finger rests, and basic instrumentation -- all the way to advanced techniques -- assessment of periodontal patients and instrumentation of the root branches of multirooted teeth, root concavities, and furcation areas. The overarching instructional goal of the text is to simplify the teaching and learning process for both educators and students. The Ninth Edition retains the many features that have positioned it as a market-leading text on periodontal instrumentation and adds new features and a content organization designed to enhance student outcomes.
