NiTi instrumentation looking for the third dimension

 

  • Nickel-titanium (NiTi) endodontic instruments: research findings and their clinical implications
  • 2D and 3D evaluation of NiTi instruments shaping ability  
  • Eccentrical preparation: different ways to touch as much root canal walls as possible
  • Apical finishing: the success is in 3D only 



Abstract

Mechanical instrumentation represents a crucial step in the control of intracanal microbial infection for successful root canal treatment. The anatomy of the root canal is often oval, while the tools and techniques today are designed to work ideally in circular ducts. Consequently some changes in operational techniques and/or endodontic instruments must be carried out during the shaping of the endodontic system.

Characteristics of new heat-treated files as flexibility, fracture resistance and lack of super elasticity allow adequate anatomically driven preparations even for highly curved canals. 2D and 3D evaluation of prepared root canals are needed to evaluate the shaping ability of endodontic files made by conventional or heat-treated NiTi. 

The challenges to reach the third dimension of root canal systems involve the search to touch as much root canal walls as possible and the correct selection of the final apical diameter. For these reasons, NiTi endodontic instruments eccentrically used and different dimensions of optional files for apical finishing are required to optimize the procedures of endodontic treatment.
