Description

Comprehensive reference on diagnostic oral pathology in animals with clinical correlates

Veterinary Oral and Maxillofacial Pathology, Second Edition is a comprehensive reference to diagnostic pathology in the oral and maxillofacial region in animals, focusing on information most useful for diagnosis and patient management in clinical practice. The book features high-quality images, including clinical photographs, radiographs and other imaging modalities, gross pathology, histopathology, special stains, immunohistology, ultrastructure, molecular diagnostics, and numerous diagrams. The work focuses on dogs, cats and horses but also offers comparative information for rodent, ruminant, reptile, and exotic patients.

The Second Edition adds new chapters focused on oral medicine of small animals and oral and maxillofacial disease of horses, with expanded and improved images and updates throughout. A companion website presents video clips of narrated scanned slides. This edition features multiple authors who are subject matter specialists in oral medicine, viral disease, dermatopathology, and equine dentistry.

Veterinary Oral and Maxillofacial Pathology covers all aspects of oral pathology, including:

• Odontogenesis and histological features of normal oral tissues, including oral mucosa, tonsils, lips, teeth, incisive papilla and ducts, salivary glands and jaw bones

• Diagnostic utility of differential diagnoses, the considerable ambiguity and morphologic overlap of some oral lesions, and the ever-evolving state of lesion classification

• Taxonomic controversies, with pros and cons of different viewpoints to allow readers to make their own decisions

Veterinary Oral and Maxillofacial Pathology is a one-of-a-kind reference for veterinary pathologists, veterinary dentists, resident trainees, interns, students, and veterinary practitioners.
