الملخص EN

Background &Objective: Rotary files have several advantages, easy for general practitioners, reducing the time for treatment and achieving Schilder rules in root canal preparation.

Many files has been manufactured till now.

The aim of this study was to compare two rotary systems; one is of reciprocating type and the other is protaper in apical transfer after preparation.

Materials & Methods: The sample was 30 extracted teeth with straight root canal identified after apical radiography cleaned and kept in Thymole for 48 hours.

Access cavity was achieved and all teeth were put in autopolymerized resin, 15 teeth were prepared by protaper and 15 with reciproc.

With digital dental x-ray and by the use of Adobe Photoshop CS5, the apical transfer was measured .spss 16 edition was used to analyze the results.

Results: There is on difference in apical transfer (Zipping) in both groups ( p< 0.05) Conclusion: Within the limitation of this study: There was no difference in the apical transformation between protaper and reciproc files.
