Fracture Strength of Endodontically Treated Teeth with Different Access Cavity Designs

5 (1 vote)

The purpose of this study was to compare in vitro the fracture strength of root-filled and restored teeth with traditional endodontic cavity (TEC), conservative endodontic cavity (CEC), or ultraconservative ‘‘ninja’’ endodontic cavity (NEC) access. 

At the conclusion, participants should be able to:

  • Describe the principles of traditional endodontic cavity (TEC), conservative endodontic cavity (CEC) and recent “ninja” endodontic access cavity (NEC).
  • Discuss the influence of different access cavity designs on fracture strength of root-filled and restored teeth.
  • Evaluate the benefits and disadvantages of the new ultraconservative “ninja” endodontic cavity access.
