Covering pathology according to clinical appearance, this text makes it easy to quickly identify and diagnose oral disease presentations. New and improved photos have been added to this edition, along with cutting-edge information on disease etiology and treatment. Coverage of pain, xerostomia, dysgeusia, and halitosis is significantly expanded, and discussions of the molecular basis of cancers reflect the rapid advances in molecular medicine. An updated companion CD-ROM provides excellent preparation for clinical situations and for success on the NBDE.
