Walking dental hygiene students step-by-step through the “how to”—not just the “what” and “why”—of using periodontal and root instruments, this Enhanced 8th Edition of Jill Gehrig’s definitive resource features new chapters, new online technique videos, updated coverage of the latest evidence-based techniques and equipment, and an expanded array of online teaching and learning resources.Designed to make it easy for students to learn instrumentation, this practical book first takes students through basic skills—patient positioning, intraoral finger rests, and basic instrumentation—then covers advanced techniques, including assessment of periodontal patients and instrumentation of the root branches of multirooted teeth, root concavities, and furcation areas.

PSYCHOLOGICAL TESTING: PRINCIPLES, APPLICATIONS, AND ISSUES, Ninth Edition explains the fundamentals of psychological testing, their important applications, and the controversies that emerge from those applications in clinical, education, industrial, and legal settings. Kaplan and Saccuzzo's engaging and thorough text demonstrates how psychological tests are constructed and used, both in a professional setting and in everyday lives. Part I focuses on the core concepts that affect the evaluation of all tests. Part II discusses the major types of psychological tests, while Part III looks at present-day issues affecting testing such as stereotype threat, bias, laws, and ethics. A multitude of test profiles and sample items illustrate how psychological testing is used and reported. Real-life case studies demonstrate the uses and misuses of psychological testing, while "Technical Example" boxes help you understand complex statistical concepts.

More than a traditional study guide, the Student Workbook--written by Katherine Nicolai of Rockhurst University--truly helps students understand the connections between abstract measurement concepts and the development, evaluation, selection, and use of psychological tests in the real world. The Student Workbook contains interesting hands-on exercises and assignments, including case studies to critique, test profiles to interpret, and studies on the psychometric properties of tests to evaluate. Of course, the Student Workbook also contains traditional features such as chapter outlines and practice multiple-choice quizzes. Best of all, the workbook is presented in a three-ring binder in which students can keep other course notes and handouts. Students will discover that the Student Workbook will help them organize their study of Kaplan and Saccuzzo's text and excel on course exams, assignments, and projects!
