    Three-dimensional finite element analysis of shaping curved root canals with the ProTaper and HeroShaper systems
    (SPRINGER HEIDELBERG, 2015) MUTLU MİTİL, BİLÇEN; Mutlu, Bilcen; Kurt, Mustafa; Ekici, Bulent; Atakok, Gurcan
    In this study, we simulated the shaping of a curved root canal with the ProTaper and HeroShaper file systems using three-dimensional finite element modeling. A total of seven of the Ni-Ti rotary instruments were employed to investigate the influence of cutting geometry. A workflow was developed using the mechanical design and analysis software I-DEAS 11 and the LS-DYNA finite element package. The three-dimensional tooth model was constructed from a micro-computed tomography dental scan and a simulated canal. It was found that stresses concentrated towards the outer aspect of curvature in the apical portion of the canal when the ProTaper file system was employed. For the HeroShaper files, the stresses concentrated in the middle portion of the tooth model. Our simulated root canal procedure enables the efficacy of rotary NiTi instruments to be evaluated in a patient-specific setting. This may aid the dentist in choosing the optimal tool set and provides data for improving tool design.

    Preference Based on Reasons of Vocational and Technical Secondary Schools in Turkey
    (ELSEVIER SCIENCE BV, 2014-08) ATAKÖK, GÜRCAN; Atakok, Gurcan; Kam, Menderes; Kurt, Mustafa; Laborda, JG
    It is considered that choosing a career is one of the most important decisions in human life. Because of many reasons such as family, environment, school etc. Industry and technical occupation high school to be preferred by students' educational system is very important to adoption of developments in the world, catch up with information society and develop its international competitiveness. The education system must train qualified manpower in order to decrease unemployment and increase social welfare. Policy of educational system is important at this stage. Industry technical occupation high schools educate qualified manpower and various non-formal education institutions continuously give the employers the skills needed by sector. A survey was done among the 503 students of 10th classes in industry and technical high school in Uskudar, Istanbul, Turkey. The data was collected with survey method. It is understood that the students of educated in industry technical high school choose their school according to their own wishes abilities and gender. They also think they couldn't get enough points for university entrance exam. In addition industry technical occupation high schools give them a chance to find a job easily. It is the shortest way for job opportunities and they bring off in their life. (C) 2014 The Authors. Published by Elsevier Ltd.
