Materials for Definitive Root Canal Obturation

This scientific monograph provides a comprehensive and systematic analysis of materials designed for definitive root canal obturation, which is a key prerequisite for achieving a long-term hermetic seal in endodontic therapy. The text is structured around the analysis of core obturation materials and specialized sealers. Core options are thoroughly discussed, focusing on the composition, physical-mechanical characteristics, and biological properties of gutta-percha and Resilon, as well as coated, silver, and titanium cones. The fundamental principles of obturation are defined through Grossman’s requirements, analyzing microleakage and seepage, material adhesion, sealer penetration into dentinal tubules, and the monoblock concept. Key physical properties, such as paste flow, setting time, solubility, and radiopacity, are critically evaluated alongside biological safety and biocompatibility standards.

A significant portion of the monograph is dedicated to the detailed classification and comparative analysis of sealer groups based on their chemical composition. This includes traditional zinc oxide-eugenol, glass ionomer cement, and calcium hydroxide-based sealers. Furthermore, resin-based sealers are extensively analyzed, distinguishing between methacrylate, epoxy, and oil-based resins, followed by an overview of silicone-based sealers. Finally, the work highlights contemporary advancements in the field of bioceramic materials, detailing their general composition, classification, and biological advantages. Special clinical focus is directed toward the MTA group of materials, Biodentine, and bioceramics in the strict sense, presenting their superior biocompatibility, tissue-healing induction, and resistance to degradation. This monograph serves as an authoritative guide for understanding the clinical performance and material science governing predictable endodontic outcomes.
