An in vitro comparison of root canal transportation by reciproc file with and without glide path.

Objective: The aim of ideal canal preparation is to prevent iatrogenic aberrations such as transportation. The aim of this study was to evaluate the root canal transportation by Reciproc file with and without glide path.

Materials And Methods: Thirty acrylic-resin blocks with a curvature of 60° and size#10 (2% taper) were assigned into two groups (n= 15).

Comparing the Fracture Rate of Hero 642, FlexMaster and Mtwo in the Simulated Canals.

Introduction: File fracture is one of the main procedural mishaps in endodontic treatment. The aim of this in vitro study was to compare the fracture rate of three NiTi rotary systems; Hero 642, Mtwo and FlexMaster in artificial canals.

Methods And Materials: In this study, bovine long bone was used.

Comparison of two canal preparation techniques using mtwo rotary instruments.

Introduction: Root canal preparation is an important process in endodontic therapy. Nickel-titanium (NiTi) rotary file system can be used in single length technique (simultaneous technique) without early coronal enlargement, as well as in crown-down method. The purpose of this in vitro study was to compare single length with crown-down methods' shaping ability using Mtwo NiTi files.
