This book explores how artificial intelligence is reshaping diagnostic and therapeutic paradigms in contemporary dentistry and offers step-by-step guidance through real-life cases. It is divided into two main sections. The first section presents a systematic approach to AI-assisted diagnostic procedures, including anatomical assessment of the jaws, detection of caries and tooth wear, evaluation of oral lesions, and periodontal analysis. It also examines the current limitations and ethical considerations surrounding the deployment of AI in diagnostic contexts. The second section delves into AI-based digital planning tools, covering advanced techniques in tissue segmentation, orthodontic treatment planning, oral surgical simulations, and prosthetic and restorative design. Each chapter integrates theoretical foundations with clinical applications, supported by emerging research and case-based insights. This book serves as a resource for integrating artificial intelligence into dental workflows, offering evidence-based guidance and fostering interdisciplinary dialogue between dental science and computational innovation.
