This book presents a focused and evidence-based overview of the role of hard tissue lasers in conservative dentistry. It integrates the principles of laser physics with detailed discussions on laser-tissue interactions involving enamel and dentin. Emphasis is placed on biological responses, clinical safety, and the influence of laser use on adhesion and restorative outcomes. The text critically examines commonly used hard tissue laser systems and their applications in caries management, cavity preparation, smear layer modification, and minimally invasive restorative procedures.
