This updated Third Edition of General and Oral Pathology for the Dental Hygienist provides the information students need to develop an understanding of basic pathology and recognize the clinical manifestations of oral and systemic disease. In accordance with ADEA Curriculum Guidelines, which stress the recognition of oral disease based on clinical signs and symptoms, the oral pathology section is uniquely organized by distinct clinical/radiographic features of oral lesions to help students evaluate and categorize lesions according to appearance, emphasizing the concept of differential diagnosis. This edition features new "Oral Medicine Considerations" that highlight the relationship between oral and systemic disease, a stunning collection of art work with over 600 images, and a wide range of online resources, such as case studies and practice questions, that reinforce student learning.
