With an emphasis on recognizing periodontal problems and suggesting appropriate treatment, Periodontology for the Dental Hygienist, 4th Edition, covers the essential information that dental hygienists need to provide effective client care. Full-color illustrations and a focus on evidence-based research help you understand and apply the latest in periodontal therapy, from initial patient evaluation to patient education. This edition includes updates on issues such as the links between oral and systemic health, dental implants, and the use of lasers. Written by Dorothy Perry, Phyllis Beemsterboer, and Gwen Essex, all experienced dental hygienists and clinical instructors, this reference also prepares you for success in classroom tests and on the National Board Dental Hygiene Examination (NBDHE).
