The sixth edition of this popular text reflects an increased emphasis on nutrition, school-based dental health clinics (SBHC), and health promotion. It focuses primarily on the clinical application of primary preventive dentistry procedures to control plaque diseases. The user-friendly format features learning objectives, self-evaluation questions, an extensive list of updated references for each chapter; and now, a comprehensive website that permits students to take a “mock examination” at the end of each chapter, giving them a means of self-evaluation at their level of attainment.
