Comparison Of Root Canal Transportation And Centering Ability Prepared With Two Single Files Rotary Systems Using Cone Beam Computed Tomography Scanning (Ex Vivo Study), Asmaa El-Hady, Mervat Fawzy, Hager El Naby
Comparison Of Root Canal Transportation And Centering Ability Prepared With Two Single Files Rotary Systems Using Cone Beam Computed Tomography Scanning (Ex Vivo Study), Asmaa El-Hady, Mervat Fawzy, Hager El Naby
Al-Azhar Journal of Dentistry
Purpose: The purpose of this study was to compare and evaluate canal transportation and centering ability of 2 single nickel-titanium rotary instruments, one manufactured by twisting (Twisted File) and the other by grinding (OneShape) using Cone- Beam Computed Tomography scanning (CBCTs).Materials and Methods: Forty mesiobuccalcanals of mandibular molars with an angle of curvature ranging from 25° to 35° and radius <15 mm were divided according to the instrument used in canal preparation into 2 groups (20 samples each): Group I: instrumented with Twisted File (TF) and Group II: instrumented with OneShape (OS). Each group was subdivided into subgroups (SG) A and B according to the technique of root canal preparation (single or modified). Canals were scanned using an i-CAT CBCT scanner before and after preparation to evaluate the change in the angle and radius of root canal curvature as well asthe amount of canal transportation and centering ratio at 1, 3, and 8 mm from the apex.The significance level was set at P≤0.05. Results: At 1mm level, TF instruments used with modified technique produced a statistically significant less canal transportation compared to OS instruments (P ≤ 0.05). While at 8mm level, OS instruments used with single file technique produced a statistically significant less canal transportation andmore centered canal preparation compared to TF instruments (P ≤ 0.05). Conclusions: TF and OS single files systems used in continuous clockwise rotation are capable of preparing root canals with moderate and sever curvature, with minimal apical transportation. Cervical pre-flaring of the canal has an impact on canal shaping where it enhances the performance of Twisted File instruments. Twisted files with 0.08 tapers could be used for apical preparation without creating severe aberrations.

Surgical Templates For Dental Implant Positioning;Current Knowledge And Clinical Perspectives, Mohammed Kola, Altaf Shah, Hesham Khalil, Nehad Harby, Ahmed Rabah, Seham Sabra, Deepti Raghav
Al-Azhar Journal of Dentistry
Dental implants have been used in a variety of different forms for many years.Since the mid‑20th century, there has been an increase in interest in the implant process for the replacement of missing teeth. Branemark was one of the initial pioneers who applied scientifically based research techniques to develop an endosseous implant that forms an immobile connection with bone. The need for a dental implant to completelyaddress multiple physical and biological factors imposes tremendous constraints on the surgical and handling protocol. Metallic dental implants have been successfully used for decades, but they have serious shortcomings related to their bony union …
