The aim of this study was to determine the fracture incidence of WaveOne Primary reciprocating files and the time required for shaping of curved canals based on the experience of the operator. A total of 109 mesiobuccal canals of permanent molars extracted with an angle of curvature of >25°-45° according to Schneider were randomly assigned to four groups. An experienced operator (endodontist) and an inexperienced operator (student) each shaped one of two groups: one ...

The aim of the study was to evaluate cyclic fatigue resistance of two NiTi instruments and to analyse their surface, fractographic and matrix morphology under ESEM/EDS and optical microscopy. WaveOne Primary and ProTaper Universal F2 brand new instruments were subjected to fatigue testing in an artificial canal with 5.0 mm radius and 60° angle of curvature. Seventy-two instruments were divided into three groups (n = 24), according to the selected kinematics: WaveOne using reciprocation (A); ...
