Comprehensive and up to date, "Dental Hygiene, 3rd Edition" offers complete coverage of today's dental hygiene skills and theories - all based on the Human Needs Model for better hygienist/patient communication. With a strong focus on clinical application, each section closely follows the critical thinking and clinical assessment approach that a hygienist must use in the classroom, clinic, and practice. Clinical competencies at the beginning of each chapter provide a clear, quick overview of exactly what you need to know, and procedure boxes with detailed steps and rationales ensure that you understand the reasoning behind each step in the competencies. In addition, new chapters on caries risk assessment and the oral-systemic health connection keep you up to date with today's major areas of research.
