Morphological Changes of Apical Foramen in Curved Root Canals after use of Different Heat Treated NiTi Rotary Files. A Scanning Electron Microscopic Study
Tahira HamidDj College of Dental Science and Research, Modinagar, Ghaziabad, IndiaObjective: The aim of the present study was to evaluate the effect of heat treated NiTi files Trunatomy and XP endo shaper on the apical foramen deformation and enlargement in curved root canals using area, circularity and feret’s diameter ratio.
Materials and methods: 60 Mesiobuccal roots of maxillary and mandibular molars with vertucci type II root canal were selected. The teeth were decoronated using carborundum disc and the root length of 13mm were standardized using a digital caliper. The Preoperative scanning electron microscope was done and samples were divided into 4 groups. Stainless steel (SS), Protaper universal (PTU), XP Endoshaper (XPS)and Trunatomy (TRN) group. After instrumentation the post operative scanning electron microscope images were taken. Area, circularity and ferret’s diameter was calculated before and after instrumentation using image j software.
Results: The area after instrumentation increases in all groups but the SS and PTU shows statistically significant difference as compared to TRN and XPS.The circularity tends towards 0 in case of SS and PTU and canals became ellipticals after instrumentation. However, TRN and XPS shows no difference. There is no significant difference is ferret’s diameter before and after instrumentation.
Conclusion: Foramina enlargement occurs regardless the type of file system used. The Hand stainless steel files and PTU result in significant foramina deformation when instrumented up to apical foramina. However, TRN and XPS promote minor alteration at the foramina which are not statistically significant. (EEJ-2024-01-20)
