Deformation and fracture incidence of Reciproc instruments: a clinical evaluation.

submitted by: gplotino
Aim To investigate the incidence of fracture and deformation observed on Reciproc instruments after clinical use. Methodology A total of 1696 Reciproc NiTi instruments that were discarded after normal clinical usage over 30 months were collected, 1580 instruments were R25 (93%), 76 were R40 (5%) and 40 were R50 (2%). The treatments included 3780 root canal preparation, 3023 primary treatments and 757 retreatments. Root canal preparation was standardized and followed the manufacturer's...
