The triple helix cutting edge helps in circumferential debris removal and the helical angle at the cutting edges prevents screwing of the file in the canal. Preparation file (PF: #20/0.04) has been subjected to C wire heat treatment (Controlled memory of Ni Ti) which provides the user with a unique advantage to pre-bend the file for easier access to the root canal and elimination of constraints.The three active cutting blades at three radii centering to the canal axis and a variable pitch between each cutting edge helps to eliminate the screwing effect of the file, when in use, which is a major advantage of this file. The asymmetrical cross-section of this file facilitates active removal of debris. Glide Path File (GPF: #14/0.03) has not been heat treated and is ideal for creating a smooth glide path especially in case of narrow and curved canals.The increased flexibility of this file prevents lodgment of the file in the dentinal walls during usage. The file, as the name suggests is used for coronal flare only and it facilitates the safe movement of succeeding files by removing the coronal debris. The Coronal Flare file (CF file: #25/0.09) has been made with T-Wire heat treatment which results in better flexibility and cyclic fatigue resistance as compared to instruments manufactured using the traditional austenite Ni Ti alloy.Let us have a close look at the specific characteristics of each file in this system, which makes it completely unique: The corresponding gutta percha points and paper points (UF1, FF2, FF3) which perfectly complement the files complete the entire kit. Recommended speed is 400 rpm and recommended torque is 1.8 Ncm for CF and GPF while it is 2.5Ncm for PF, UF1, FF1 AND FF2. The GenENDO files are available in a set of 4 files: Coronal flare (CF), Glide Path File (GPF), Preparation file (PF) and Universal Finishing file(UF1) ( Figure 1) or a set of 6 files (Finishing files:FF2 and FF3 in addition to the 4 file set). This unique combination of flexibility and fracture resistance makes these files almost universally acceptable in almost all clinical situations. The rationale behind such extensive exercise lies in the fact that since each file has a specific function to perform and is meant to work in different area of the root canal, their structural designing and properties are meant to be unique in order to optimize the clinical efficacy without causing procedural errors. The utilization of different technologies in fabrication of each of these files, makes them highly unique. The GenENDO files system has been designed keeping the simplicity of use in mind, with dedicated files for coronal flaring, establishing glide path, efficient preparation and shaping of the canal, and smooth cleaning and finishing. These files are unique in design and metallurgy and perfectly represent ‘ a perfect combination of flexibility and strength’. The new GenENDO™ (by Micro Mega, manufactured specially for Coltene India) heat- treated nickel titanium rotary files which are specially designed to give quick and predictable results for endodontic treatments, seem to perfectly match these criteria in totality. The success of this system would perhaps lie on the detailed structural engineering and design of the rotary files, with different heat treatments being given to files, meant for usage in different parts of the root canal. While there can be no ideal files for every root canal, considering the variation in diameter, shape, curvature etc., the smart need of the hour is to design a system, which can cater to almost all canal configuration types. 3, 4However, as the use of these fast cutting Ni Ti Files has progressed across the globe, the instrument related procedural errors such as ledge formation, transportation, perforations etc. Rotary endodontic instruments have brought a paradigm shift in the field of Endodontics. The researchers, across the globe have been working day and night to create the ‘wonder instruments’ which can make the dynamic endodontic procedure simpler and predictable. 2 The dental professionals, in addition to managing routine cases, also have to deal with more complicated cases such as those with very fine and curved canals. 1 With rise in number of patients seeking endodontic therapy, the use of rotary endodontic files has substantially increased as well. Success in endodontic therapy relies on thorough cleaning and shaping of root canal system followed by its complete obturation.
