Variations in the root canal’s anatomy play an important role on endodontic therapy success, primarily in teeth with pulp necrosis. Traditionally, the preparation of root canals was performed with the use of stainless steel hand files; but over the years, new flexible instruments were introduced to prevent or minimize iatrogenic errors in shaping the root canal system. In most of recent publica...

This study compared the cyclic fatigue resistance of OneShape (OS) instrument which used continuous rotation with WaveOne (WO) instrument which used reciprocating motion. OS size 25, 0.06 taper and WO primary size 25, 0.08 taper were used in simulated canals with 45°, 60°, and 90° angles of curvature until fracture. The number of cycles to fracture (NCF) was recorded to evaluate cyclic fatigue ...

Evaluar la influencia del operador sobre el transporte apical y centrado de instrumentación endodóntica utilizando WaveOne Gold en canales radiculares simulados resina acrílica. Se asignaron 32 acrílica a dos grupos (n = 16). El grupo 1 conformado por estudiantes inexpertos 2 especialistas área endodoncia. Estos se instrumentaron hasta un tamaño 25/07 con lima Primary Gold. Para evaluar u...
