Surface Defects and Crystalline Structural Changes of Used Reciproc and Reciproc Blue Rotary Nickel-Titanium Files (Vitro Study)
Ahmed Mohamed Hamza;
Abstract
The aim of the study was to evaluate surface defects and crystalline structural changes in reciproc and reciproc blue rotary nickel-titanium files after use.
Sixty lower first molars were collected, Proximal radiographic views were taken to mesiobuccal and mesiolingual canals exhibiting a curvature, average between (25o - 35o). The method was done according to Schneider method by using Image J software.
The each tooth the mesiobuccal canal is done by reciproc file but the mesiolingual by reciproc blue file. EDTA used during the mechanical preparation. After each file the canal was irrigated by 5.25% NAOCL.
A total number of 22 files were used, 20 experimental files and 2 controlled files (one from each system for X-Ray diffraction assessment). Then each group was subdivided into 2 subgroups.
Group I: 60 MB canals were prepared using 10 Reciproc files.
Group II: 60 ML canals were prepared using 10 Reciproc blue files.
Classification of each group into two subgroups A & B:
