ترجمة الملخص

Aim: to compare the shaping ability of Threerotary systems(Protaper Universal, Protaper Nextand F360) and K-file hand instruments in curved root canals of extracted human molarsregarding maintenance the orginal shape of curved canal, preparation time and the safety of instrumentation.Materials and methods:fortyextracted molars with curved canals were chosen. The curvature of root canals was determinedby (Auto-Cad), andthe canal curvatures ranged between(15-40o) and the radii (3-10) mm, then the sample was randomly divided into four groups: n1=n2=n3=n3=10. Group(1): was prepared using (Ni-Ti) K-file hand instruments (Stand), group(2): prepared by Protaper Universal (PTU), group3: prepared by Protaper Next (PTN), whereasgroup (4) prepared by F360. The curvature after preparation, Time preparationand change of working lengthwere evaluated.In addition, the number of fractured files was recorded.Data were collected and statistical analysis was conducted. Results:The fourpreparationsystems(PTU, PTN,F360,Stand)have caused significant change in original canal curvature (P<0.05). The PTU system resulted in more straightening during instrumentation compared to single-file system F360 (P<0.05), On the other hand, there were no significant differences among (PTU, PTN, Stand)systems in straightening of canal curvature (P>0.05). Furthermore, F360 were significantly faster than other systems (PTU, PTN, Stand) duringpreparation of curved canals (P<0,001). However, both systems: PTN and Stand were significantly faster than PTU during preparation of curved canals (P<0,001).During preparation, only one PTU file has fractured, however there was no significant among groups regarding the instrument fructure (P>0.05).in addition, there were not significant differences among groups in regard to change of working length (P>0.05).Conclusion:under the conditions of this study, it can be concluded thatall instruments caused changing in original canal curvature. However,the single-file F360 is safe and proper for curved canal instrumentation. The new generation PTN was faster than old one PTU, but during preparation both instruments caused same straightening in curved root canals.
