Aims: The aim of the present in vitro study was to evaluate apical seal in the root canals containing separated instrument (Hand k files, Hyflex CM and Reciprocation Neoendo file) using dye penetration method. Study Design: An In vitro study. Place and Duration of Study: Department of Conservative Dentistry & Endodontics, SGRD Institute of Dental Sciences, Amritsar, Punjab, India between Feb 2022 and Nov 2023. Methodology: In this study 3 different file systems were used for root canal preparation of 90 teeth. The files were intentionally separated (n=20 each) at the apical third and tooth was obturated using lateral condensation method along with 2 control groups (n=5 each) and the analysis of microleakage was done using dye penetration method under stereomicroscope. Results: The highest mean microleakage was observed in Hyflex CM (5.49mm) group followed by Hand K file (3.338 mm) whereas least microleakage was observed in samples containing separated Reciprocation file Neoendo (3.220 mm). Conclusion: Maximum microleakage was observed in Hyflex CM files and least in Reciprocation File Neoendo group.
