This chapter is dedicated to the fundamentals of endodontic treatment and dental materials science. It provides a detailed analysis of the complex anatomy of root canal systems, as well as the main approaches to preserving or removing the neurovascular bundle: vital, devital, and biological methods of pulpitis treatment.
A significant part of the section is devoted to materials. We will examine the evolution and properties of temporary and permanent filling materials: from amalgams and classical cements to modern glass ionomers, composites, and adhesive systems. You will study the algorithms for working with them, the rules for applying therapeutic and base liners, as well as the nuances of polymerization.
During practical classes and tests, questions most commonly focus on protocols for mechanical preparation (specifically the Crown-Down technique) and irrigation of root canals. Pay special attention during your preparation to permanent obturation methods (guttapercha, pastes) and make sure to review typical errors and complications in caries treatment and endodontic intervention. This is the foundation required for clinical practice.
This is due to the continuous plastic function of odontoblasts. Throughout life, they deposit secondary dentin on the walls of the tooth cavity, reducing its volume.
What are pluggers used for in the context of working with amalgams?
Pluggers are used for placing and condensing amalgam during retrograde filling, which is performed during a surgical operation—root-end resection.
What is the difference between opening and unroofing the tooth pulp chamber?
Opening (trephination) is the creation of a small point-like opening to connect with the pulp chamber (done with a round bur). Unroofing is the complete removal of the pulp chamber roof with a fissure bur for free access to the canals.
When probing the floor of the cavity, the instrument characteristically "drops" into the pulp chamber, or a drop of blood appears in the created point-like opening.

What is the main difference between vital and devital amputation?
During vital amputation, the radicular pulp remains viable, allowing the roots to form. During devital amputation, devitalizing agents are applied, and the radicular pulp is mummified.
