This book comprises a brief review of commonly encountered endodontic emergencies. this book will be of great help to dental practicetioners and dental students in dealing with various endodontic emergencies. henceforth this is a practical guide to deal with difficult situations encountered during clinical practice. last but not the least we should focus on prevention of these kind of endodontic emergencies.

Regenerative endodontic procedures can be defined as biologically based procedures designed to create and deliver tissues to replace diseased, missed and traumatized pulp-dentin complex.Presently two concepts are seen in regenerative endodontics to treat non-vital teeth- one is the active persuit of pulp-dentin regeneration to implant or regrow pulp (tissue engineering technique) and the other in which new living tissue is expected to form from tissue present in the teeth itself, allowing continued root development (Revascularization).
