This text shows how developmental and structural microscopic anatomy form the foundation for everything students will need to know for effective study of oral health care. This text makes a connection between concept and clinical application, providing an explanation for the cause-and-effect nature of clinical oral manifestations. Clinically focused content provides essential knowledge of the basics of oral biology with an emphasis on its relationship to clinical practice and a focus on the patient. Full-color art program includes many high-quality illustrations, histographs, micrographs, and clinical photos depicting various stages of development of the oral structures. Clinical Comment and Consider the Patient boxes help you apply information to clinical practice and patient care by describing clinical tips, points of interest, and patient situations. Self-evaluation questions are included at the end of each chapter, helping you review for classroom and national board exams. Key vocabulary is listed at the beginning of each chapter and highlighted in boldface within the text. Suggested readings at the end of each chapter allow you to research classic and new studies. Expert author Daniel Chiego has 40 years of experience in research and education in oral embryology and histology, and has directed the dental and dental hygiene courses of study in these topics at the University of Michigan for more than 15 years. An Evolve companion website provides practice quizzes, vocabulary flashcards, labeling exercises, and links to related websites for further research and study. NEW and UPDATED content on thyroid development and hormones, tooth development, dentin, collagen, and cemental repair incorporates findings from recent studies. UPDATED and EXPANDED art program accurately depicts the anatomy of oral and facial tissues and provides high-quality images to help improve comprehension.
