This book analyses different types of retrograde filling materials. The major goals of root canal treatment are to clean and shape the root canal system and seal it in 3 dimensions to prevent reinfection of the tooth. Although initial root canal therapy has high degree of success, failures can still occur after treatment.
Recent studies reported failure rates of 14%–16% for initial root canal treatment. Lack of healing is attributed to persistent intraradicular infection residing in previously uninstrumented canals, dentinal tubules, or in the complex irregularities of the root canal system. The extraradicular causes of endodontic failures include periapical actinomycosis, a foreign body reaction caused by extruded endodontic materials, an accumulation of endogenous cholesterol crystals in the apical tissues, and an unresolved cystic lesion.
This book is composed of ten chapters and begins with the need of root-end resection. The succeeding chapters deal with the method and concept of root-end resection, root end preparation to receive the material, ideal requirements of materials to be placed in the resected and prepared root-end. The concluding chapters describe various root-end materials available in the market so far and their properties, focusing on each individual material one by one, their advantages and disadvantages.
This book will prove useful to Endodontists and Researchers in the field of endodontic surgeries & root-end filling materials. Also it would provide the undergraduate and postgraduate students an easy way of reference for covering a broad spectrum of Root-end filling Materials available today, in lucid and simple language.

Excerpt from the Book
AMALGAM
Definition and Introduction: An amalgam is an alloy of a metal that contains mercury as one of its constituents.89 (Fig.5)
Historical perspective of amalgam as a root end material:7,90 It is the most extensively used retro-filling material from past seven decades. One of the first reports of placing amalgam as a root end filling subsequent to resection is attributed to Farrar.

Frequently Asked Questions
What is the core focus of this book?
The work focuses on the principles and practices of surgical endodontics, particularly regarding root-end resection, the preparation of the root-end, and the evaluation of various filling materials used to achieve an apical seal.
Which materials are covered as root-end fillers?
The book covers a broad spectrum of materials, ranging from traditional ones like Amalgam, Silver cones, and Gold foil to modern bioceramic and resin-based materials such as MTA, Biodentine, and the Resilon/Epiphany system.
What is the primary objective of a root-end filling?
The objective is to create a physical and biological seal at the apex of the root to prevent the movement of bacteria and toxins from the canal system into the surrounding periradicular tissues.
What surgical method does the book prioritize for preparation?
The book emphasizes the use of modern microsurgical techniques and ultrasonic instrumentation, which allow for more conservative and precise root-end preparations compared to traditional bur methods.
What is considered the "gold standard" material in this field?
Mineral Trioxide Aggregate (MTA) is widely considered the gold standard due to its excellent sealing ability and favorable biological tissue response.
What are the key evaluation criteria for these materials?
The materials are primarily evaluated based on their sealing ability, cytotoxicity, handling characteristics, and their capacity to promote periradicular tissue regeneration.
How does moisture affect the performance of these materials?
The book highlights that many materials, such as Amalgam and Gallium alloys, are highly sensitive to moisture, whereas materials like MTA are designed to set and perform effectively in the presence of moisture.
What is the significance of the "double seal" concept?
The "double seal" refers to combining the physical seal provided by the filling material with the "biological seal" formed by the subsequent deposition of cementum on the cut root face.
