  • Abstract

Abstract
Aim: Evaluate the fracture incidence of Reciproc R25 instruments after clinical use by graduate students.
Methodology: An evaluation was conducted of 2,356 case records of endodontic treatment provided by graduate students over a period of 24 months. Included in the analysis were 1,958 treatments performed using the Reciproc R25 file on premolars and molars, following the manufacturer's instructions. Dental pulp status was not taken into account. The cases of fractures were evaluated and recorded.
Results: There were 12 fractures (0.61%), 4 of which occurred 16 mm from the instrument tip (0.20%) and 8 of which occurred approximately 5 mm from the instrument tip (0.41%). Of this total, 25% occurred in pre-molars and 75% in molars.
Conclusion: There was a low incidence of fractures during instrumentation of root canals with Reciproc R25 files in premolars and molars by graduate students.
