Evaluation of apical transportation by three rotary systems in extracted teeth with curved canals = Evaluación de la transportación apical con tres sistemas rotatorios en dientes extraídos con conductos curvos /
The aim of this study was to compare the apical transportation in extracted teeth using three different rotary nickel-titanium systems (Mtwo, Hyflex CM, and Typhoon). Sixty extracted first molars were randomly divided into three groups (n=20 in each group) with similar root canal curvatures (25-52 d...
