## Overview

Neoendo Flex Files #20/4/21mm are heat-treated, triangular cross-section rotary endodontic files engineered for superior flexibility and cutting efficiency. Operating at 350 RPM and 1.5 Ncm torque, these files resist flute deformation under stress, ensuring faster, cleaner root canal treatments. Packaged in sets of six, they offer a cost-effective solution for professional dental use.

## Description

Neoendo flex files are one of the latest rotary endodontic files used in root canal treatment (endodontic therapy). These new endodontic rotary files were manufactured keeping in mind the limitations of conventional shape memory rotary files in endodontics. Neoendo Flex Files undergo a specialized heat treatment process to give them unique flexibility characteristics. Shape memory nickel titanium rotary endodontic files have the limitation of reduced cutting efficiency due to heat treatment in addition to opening of the flutes when stress levels are encountered in the canal. This results in prolonged treatment time and apical extrusion of debris. Neoendo Flex Files however, utilize proprietary heat treatment methods which dos not result in the flutes opening as a result of stress. Advanced surface treatment methods are employed which results in the characteristic golden colour of the file. This surface treatment results in a far superior cutting efficiency of the files.
