Introduction: A curved, tortuous canal comes with a challenge of avoiding instrument fracture. Considering the mild diameter of the instrument tip which is expected to cut a substance as hard as dentine. It is remarkable that few instruments are broken. This study was undertaken to evaluate the efficacy of two ultrasonic system Endo Success and StartX in retrieval of fractured instrument from root canals.

Material and Methods: 40 extracted permanent Mandibular First molar which was randomly assigned as 2 groups corresponding to the StartX and Endo Success which was used during the treatment to evaluate their efficacy in removing separated instrument.

Results: Mean time required for removing file fragments was more in StartX system (51.25 ±

7.85 minutes) than Endo Success system (33.80 ± 5.80 minutes). Statistically, significant difference was present in time mandatory for removing file fragments between StartX system and Endo Success system. Most probably result in higher success rate and at the same time minimalize the quantity of dentin forfeited in Endo Success system.

Conclusion: Better visualization combined with a conservative approach selectively removing tooth structure. Tough situations in which exact tip design of Endo Success system permits access to limited work areas offer chances that are not possible with StartX system.
