Regenerative endodontics is an emerging field that aims to biologically restore the function and vitality of immature, necrotic permanent teeth. Unlike conventional apexification techniques that only resolve periapical pathology, regenerative procedures promote continued root development, thickening of dentinal walls, and revascularization of the pulp space. This book explores the principles, biological basis, protocols, and clinical applications of regenerative endodontics, highlighting its advantages over traditional methods. It also reviews current research, challenges, and future...
