Questions and Answers

What is the main objective of root canal obturation?

  • To achieve a fluid-tight seal from the coronal orifice to the apical foramen (correct)
  • To prevent release of bacterial elements in the other direction only
  • To prevent leakage of bacterial organisms only
  • To inhibit growth of any surviving bacteria only

    • What are the three main factors that success in endodontic therapy depends on?

  • Disinfection, root canal obturation, and chemo-mechanical preparation
  • Root canal obturation, accurate diagnosis, and complete chemo-mechanical preparation (correct)
  • Chemo-mechanical preparation, coronal seal, and obturation stage
