The purpose of this study was to compare and evaluate the shaping ability of the three different Ni-Ti file systems used by undergraduate students.Fifty undergraduate students prepared 150 simulated curved root canals in resin blocks with three Ni-Ti file systems -ProFile � (PF), Manual ProTaper � (MPT), Rotary ProTaper � (RPT). Every student prepared 3 simulated root canals with each system respectively. After root canal preparation, the Ni-Ti files were evaluated for distortion or breakage. Assessments were made according to the presence of various types of canal aberrations. The pre-and post-instrumented canal images were attained and superimposed. The instrumented root canal width were measured and calculated for the net transportation (deviation) and the centering ratio.Under the condition of this study, both ProTaper � systems allowed significantly more removal of root canal wall than the ProFile � system. In the important other aspects such as the centering ratio, there was no significant differences between the systems. Novice dental students were able to prepare curved root canals with any kinds of Ni-Ti file systems with little aberration and great conservation of tooth structure. Students want to learn effective methods and at the same time simple rotary procedures. The rotary ProTaper � systems were one of the most compatible to these students from the point of view of cutting ability. The ProFile � system was also compatible in safe and gentle shaping.

This study was done to evaluate transportation of the apical foramen after 0.5 ㎜ overinstrumentation by ProFile, ProTaper and K 3 in simulated resin root canal. Sixty simulated resin root canal with a curvature of J and S-shape were divided into two groups. Each group consisted of three subgroups with 10 blocks according to the instruments used: ProFile . Simulated resin root canal was prepared by ProFile, ProTaper and K 3 with 300 rpm by the crown-down preparation technique. Pre-and post-instrumentation apical foramen images were overlapped and recorded with Image-analyzing microscope 100X (Camcope, Sometech Inc, Korea). The amounts of difference in width and dimension on overlapped images were measured after reference points were determined by Image Analysis program (Image-Pro � Express, Media Cybernetic, USA). Data were analyzed using Kruskal-Wallis and Mann-Whitney U-test.The results suggest that ProFile showed significantly less canal transportation and maintained original apical foramen shape better than K 3 and ProTaper.

“…NiTi-alloy has the advantages of super elasticity and the shape memory effect (6). Various brands of NiTi system have been introduced to the market, having a slightly different design for its cross-sectional shape, helical angle, and "radial lands" compared to each other (7). The most commonly used materials are Stainless steel and the Nickel-Titaniu m alloy.…”

Aim: A im of this study is to evaluate the lateral forces on the instrument in the apical 3rd of curved canal with two Nickel Titaniu m rotary systems. Methodol ogy: One brand of instrument RaCe no 25 was scanned with micro computed tomography to produce a real-size, 3-d imensional (3-D) model and was compared with Anexas (designed by authors). The stresses on the instrument during simu lated shaping of the root canals were analyzed numerically by using a 3 D fin ite element (FE) package, taking into account the nonlinear mechanical behavior of the NiTi material. Results: Anexas shows lowest values for force generation in the apical 3rd of canal as compared to RaCe wh ich shows higher values. Conclusion: With FE simulation of root canal shaping by two files, it was observed that different instrument designs would experience unequal amount of force generation in canal, as well as reaction torque from the root canal wall.
