The success rate of fractured instrument retrieval varies because it is dependent mainly on several factors, including the visibility of the fractured instrument, the length of the fractured instrument in relation to the curvature of the canal, and the techniques applied to each case. This review aims to update the present status on the removal of fractured instruments to identify factors and variables that could affect the success of fractured instrument retrieval based on preparation and instrument retrieval techniques. On the other hand, future directions of fractured instrument retrieval should focus on managing non‐visible fractured instruments since the removal of those instruments is deemed unpredictable with the current techniques. In contrast, the removal of visible fractured instruments is considered predictable now. Another possible direction is that there might be no more instrument fractures due to possible significant changes in the root canal preparation technique, which may dispense with rotary instruments.
