Endodontic Materials

Objectives and Goals

  • To understand the rationale for the various uses of calcium hydroxide based on its physicochemical properties.
  • To know how the physical makeup of MTA affects its handling characteristics.
  • By understanding the properties of nickel-titanium to make better use of the instruments fabricated from the alloy.
  • Know how to employ bonded resin based obturation materials through an understanding of their strengths and limitations.
